New Research Shows Healthy Agriculture Means Healthier Birds – Honing our understanding of healthy agricultural schemes that promote healthy farmland birds.

How cutting your food waste can help the climate - BBC Future – Over the past few years, I have started composting and reduced my food waste by eating food – never forgetting what I have in the refrigerator. Keeping a mental inventory of fresh fruits and veggies…freezing anything that I might not use before it goes bad….has been key. I enjoy frozen bananas in smoothies more than the unfrozen! This time at home (social distancing) gives me an opportunity for another round of reducing food waste….although it’s harder now since I’ve done all the easy actions.

'Grand Challenge' review stresses global impact of microplastics -- ScienceDaily  - Where major research and discovery are needed re microplastics impact on the environment and health. Recognizing that all plastic is not the same and new tools will be needed.

Can Destroying Senescent Cells Treat Age-Related Disease? | The Scientist Magazine® - Lots of trials going on…this may be a way to extended years of healthy life (not elongate life).

This 'Blood-Red' Snow Is Taking Over Parts of Antarctica | Smart News | Smithsonian Magazine – I remember seeing snow that was the color of watermelon in Colorado…it’s algae Chlamydomonas nivalis, which is the most common type of snow algae around the world. It hasn’t been as common in Antarctica until this year.

Spotted Zebras, Yellow Cardinals, and Three-Antlered Deer: What Causes these Animal Oddities? • The National Wildlife Federation Blog – Some uncommon forms of animals we all recognize.

What Makes a Venus Flytrap Snap | The Scientist Magazine® - It’s complicated…and nuanced so that the plant only invests in digestion efforts when there is food!

Just a Tiny Fraction of America’s Plastic Can Actually Be Recycled, Report Finds - Yale E360 – We can’t send it to China any more…so it’s all on us to clean up our own mess. Unless and until we can get recycling working well…it’s important for all of us to reduce our use of plastics as much as possible. It’s hard to do.

States with highest rates of melanoma due to ultraviolet radiation identified: Several landlocked states among those with highest rates -- ScienceDaily – It’s not all about being out in the sun either. The prevalence was higher in younger females due to tanning bed usage by teen girls in the late 1990s contributing.

Interactive Infographic: How Salt Transforms Coastal Forests | The Scientist Magazine® - We noticed this process as we’ve visited Blackwater National Wildlife Refuge over the years. There are some areas that used to be marsh with some trees that are now open water.

Top 25 birds of the week: March 2020 - Wild Bird Revolution – No birding festivals in our future near term….but still enjoying pictures taken by others.

Why your internet habits are not as clean as you think - BBC Future – A good compilation of studies about energy consumption for various aspects of our online activities….maybe we can skew toward the lower energy use ones more frequently. Some of the energy, we pay for in terms of our electricity use….others are embedded in products or services we use where the energy usage is not something we see directly.

Coronavirus: How hand sanitizers protect against infections – Compound Interest – Some timely chemistry.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

Researchers Find Cell-Free Mitochondria Floating in Human Blood | The Scientist Magazine® - Surprise! Now to figure out their function….

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!

NOAA Research’ top 5 stories from 2019 – Catching up on some reading…the stories featured were the most popular on their site in 2019.

Capturing CO2 from trucks and reducing their emissions by 90% -- ScienceDaily – Research applicable to making transportation friendlier to the environment…retrofitting of existing trucks.

Rising Temperatures Are Stressing the U.S. Corn Belt - Yale E360 – It’s not just rising temperatures…it’s the shift in rainfall causing hydrologic stress during the summer months. Maybe the ‘corn belt’ could shift northward?

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

These infrared images show just how alive butterflies’ wings are – Surprise! Butterfly wings have living cells not just membranes and scales! The living cells can sense heat and the butterfly responds behaviorally.

 Flame retardants and pesticides overtake heavy metals as biggest contributors to IQ loss - ScienceDaily – There are a lot of things that are toxic in our environment these days…and children are the ones that are hurt the most…and the hurt lasts their lifetime. This study looked specifically at lead, mercury, poly-bromated diphenyl ethers (PDBE…flame retardants) and organophosphate pesticides.

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

Unusual Urban Bobcat Spotted in Washington, D.C. | Smart News | Smithsonian Magazine – Wow! There is more open area where I live (between Washington DC and Baltimore)…maybe there is a bobcat around here too.

Low doses of radiation used in medical imaging lead to mutations in cell cultures -- ScienceDaily - Discovery that radiation creates breaks that allow in foreign DNA must be confirmed in animal studies. Maybe this is just a pathway to learning more about how cells cope with natural amounts of DNA damage….or maybe we need to look again at the risk/benefit of some routine diagnostic testing.

Stunning Chronophotos of Powerful Osprey in Mid-Hunt – Very dramatic!

Surprising Beauty Found in Bacterial Cultures – The video is less than a minute…worth watching.

Top 25 Wild Bird Photographs of the Week: #Feeding – National Geographic Society Newsroom – They all must eat. I kept track of what they were eating in the pictures: snail, insect or other small invertebrate, frog, rodent, fish, lizard, algae, carrion, nectar, skink, or seeds.

Walnuts may be good for the gut and help promote heart health -- ScienceDaily – I like walnuts….now just to eat them more consistently!

HEADING TO THE FOREST: Bringing Joy, Accomplishment & Hope to Children | Children & Nature Network – Forest days for kindergarteners and nature kids from preschool to high school…backyard to back country. More examples of how education in nature is happening. This was part 2…the earlier article can be found here.

America's most widely consumed oil causes genetic changes in the brain: Soybean oil linked to metabolic and neurological changes in mice -- ScienceDaily – Start reading labels….there is soybean oil is in a lot of processed foods like mayonnaise and salad dressings….the list goes on and on. Evidently other soy products (edamame, soymilk, tofu, etc.) don’t cause the same changes observed with soy oil.

Blue Jay: A New Look at a Common Feeder Bird – Our feeder is not accessible to blue jays….but we see them at our birdbath frequently….and hear their calls in the forest and our yard trees.

Macro Photography Shows Stunning Details of Carnivorous Plants – Some botanical pictures to finish out the gleanings for this week.

Top 25 Wild Bird Photographs of the Week: January 2020 – Starting out with wild and wonderful birds this week.

Infographic: How does nature influence human health? – Most people intuitively know that nature has a positive impact…but now there is more and more research to quantify that impact.

The Plastics Pipeline: A Surge of New Production Is on the Way - Yale E360 – Just when I really want manufacturers to find ways to package products in something other than plastic….the industry has plans to ramp up production of plastic. Consumers can still make a difference with our purchases (or lack of purchase). I’m slowly but surely reducing the items I buy that come in plastic….always looking for alternatives.

New aqueous lithium-ion battery improves safety without sacrificing performance: Non-flammable, cost-efficient, and effective battery -- ScienceDaily – Hurray for all the battery research going on right now….hopefully there will be more and better options near term. It would certainly boost the speed we can transition away from fossil fuels.

Pylos Tomb Artifacts Suggest Trade Links - Archaeology Magazine – Amber from the Baltics, imported carnelian, pendant depicting an Egyptian goddess….the Greek site might have been a stop on a trade route.

Happy New Year from Amundsen-Scott South Pole Station – Kelly Brunt posted this on January 3rd….and I just got around to looking at it. She was one of our hosts at NASA for my HoLLIE class and then the keynote for our graduation. It was good to read about her recent activities!

Super Resilient Protein Structures Preserved a Chunk of Brain for 2,600 Years – Wow – what an amazing and surprising find! And there is has been some research to figure out how it managed to be preserved.

Towards Ecophilia: Being hopeful in spite of it all -I enjoyed the pictures and activity descriptions about children in nature.

How US sewage plants can remove medications from waste-water – Using granular activated carbon and ozonation….more than 95% of certain antidepressants and antibiotics can be removed. This is important to help reduce the development of antibiotic resistant bacteria and maybe other environmental harms as well. But it can be expensive.

The oldest person in the world turns 117 – I liked the last paragraph of the story the best: Last year, when Tanaka received her record for the world’s oldest person, she was asked about the happiest moment in her long life. Her reply was simple: “Now.” Wouldn’t it be great if we all could feel like that no matter how old we are!

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

A little prairie can rescue honey bees from famine on the farm -- ScienceDaily – Food crops can provide good food for honey bees…but maybe not for the whole season.

Agar Art Contest 2019: See this year’s winners – Art made with live bacteria.

Infrared Reveals Egyptian Mummies' Hidden Tattoos | Smart News | Smithsonian – 7 mummies – 3,000 years old. All the mummies with tattoos at the site were women.

Gabapentin: A Risky Answer to the Opioid Epidemic - The Atlantic Gabapentin has become the 10th most-commonly-prescribed medication in the US. It is viewed as a safer alternative to opioids for chronic pain….but it is problematic in combination with other sedating medication and it doesn’t work as well as hoped….particularly for back pain. It appears that looking for a quick fix for chronic pain is – again – not working as advertised.

Photography In The National Parks: My Favorite Spots For Great Photos – From Arches, Bryce Canyon, Big Bend, Acadia, and Padre Island.

Scientists Don't Know Why Freshwater Mussels Are Dying Across North America | Smart News | Smithsonian – It’s not just in one place….and may have multiple causes. But this just highlights that some mussel species that have already gone extinct…and our rivers are very different than their ‘natural’ state.

Scientists Use Agricultural Waste to Develop New Road Deicer - Yale E360 – Grape skins and other agricultural wastes rather than sodium chloride.

Poor Potato Crops Could Lead to a North American French Fry Shortage | Smart News | Smithsonian – Not a good year for potatoes in the US and Canada evidently. I wonder if prices will go up.

Hydration may affect cognitive function in some older adults -- ScienceDaily – Evidently overhydration has an impact on cognitive function as well…so it is important for older people to understand symptoms of both and actively manage their hydration.

Could Migraine Pain Relief Be Found In The Color Green? : Shots - Health News : NPR – Interesting research. Do green glasses help as much as the green LED light?

How everyday products are supercharging landfill gas, and what that means -- ScienceDaily – Some basic research that could be applied to getting more energy from our landfills.

U.S. States Have Eliminated Thousands of Environmental Protection Jobs Since 2008 - Yale E360 – “Neither EPA nor states have the funding they need to meet their responsibilities under the Clean Air Act, Clean Water Act, and other laws that protect the public’s health and our environment from dangerous pollution.” Not good.

How hacking the human heart could replace pill popping - BBC Future – Pacemakers are primitive compared to the devices that are being worked on now. The future implants will adjust to the situation…reading and writing to the nervous system to treat such things as diabetes, bladder control and chronic pain (and heart issues). Maybe they will address the root cause of some chronic diseases rather than just the symptoms.

Colouring Europe at Work: download our industrial heritage colouring book | Europeana Blog – Learn some history while your color.

IBM Changes the Energy Storage Game With Cobalt-Free Battery – Lots of research in the battery arena these days. This one caught my eye since I spent some of my career working for IBM. Maybe these will be part of the next-gen technology for batteries.

Tiny shells reveal waters off California are acidifying twice as fast as the global ocean -- ScienceDaily – Looking at shells of foraminifera in sediments provides a vertical record of ocean acidity.

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live.

50 Fish, 50 States: Small Stream Wonders – Cool Green Science – Lots of small fish! When we are in the streams with high school students, we often find small fish but since they aren’t what we are looking for – we simply put them back without identification. Maybe I should look for a simple small fish ID to take a long and start to photograph them too.

A Giant Treehouse 'Like A Castle' Is Destroyed By Fire In Tennessee: NPR – My sister and I visited this giant treehouse in 2012 when we were in that area of Tennessee. Sad that it’s gone.

Scientists study impact of sediments and nutrients from Conowingo Dam on Chesapeake Bay -- ScienceDaily – Close to home. The base of Conowingo Dam is where we go to view Bald Eagles. There is a lot of concern now about the sediment build up in the reservoir --- state governments and the utility are working to determine best options for prolonging the energy generation capacity of the dam and improving water quality into the bay.

Big Box Stores Leading the Shift to Renewable Energy - News | Planetizen – Wal-Mart and Target are all in….what about other big box stores? What about owners of shopping centers? Lots of stores are in leased spaces.

Five Architectural Firms Retained to Redesign National Mall Tidal Basin – Another ‘close to home’ in this set of gleanings. This one is in the District of Columbia. Think of the Jefferson Memorial and the cherry blossoms. Flooding has increased over the time we have living in this area (now over 35 years). Hope they can develop a good design and get the funding to implement it.

Manta Ray Populations Have Complex Social Structures | The Scientist Magazine® - A study of the reef mantas as they aggregate around the reefs of the eastern Indonesian archipelago Raja Ampat. The study showed two distinct groupings: one dominated by older females and the other a mix of sexes and ages.
