Ancestral variation guides future environmental adaptations      (via sciencedaily.com) 

The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.

Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows      (via sciencedaily.com) 

Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.

Ancient mint plants may lead to new medicines/products      (via sciencedaily.com) 

The mint family of herbs, which includes sage, rosemary, basil, and even woody plants like teak, offers an invigorating jolt to our senses of smell and taste. Researchers have found that these plants have diversified their specialized natural characteristics through the evolution of their chemistry, which could lead to potential future applications that range from medicine to pesticide production.

What crocodile DNA reveals about the Ice Age      (via sciencedaily.com) 

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Can elephants save the planet?      (via sciencedaily.com) 

Researchers report that elephants play a key role in creating forests which store more atmospheric carbon and maintaining the biodiversity of forests in Africa. If the already critically endangered elephants become extinct, rainforest of central and west Africa, the second largest rainforest on earth, would lose between six and nine percent of their ability to capture atmospheric carbon, amplifying planetary warming.

New discovery: Endangered Amami rabbit disperses seeds for non-photosynthetic plant      (via sciencedaily.com) 

Seed dispersal is an essential process for the evolution and ecology of terrestrial plants, making discoveries of uncommon seed dispersal agents particularly interesting. Scientists now reveal that the Amami rabbit (Pentalagus furnessi) is a major seed dispersal agent for the non-photosynthetic plant Balanophora yuwanensis. To the best of our knowledge, this is the first known instance of rabbits serving as seed dispersal agents in Asia.

Mixture of crops provide ecological benefits for agricultural landscapes      (via sciencedaily.com) 

There are often too few flowering plants in agricultural landscapes, which is one reason for the decline of pollinating insects. Researchers ave now investigated how a mixture of crops of faba beans (broad beans) and wheat affects the number of pollinating insects. They found that areas of mixed crops compared with areas of single crops are visited equally often by foraging bees.

Collision risk and habitat loss: Wind turbines in forests impair threatened bat species      (via sciencedaily.com) 

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

Low-impact human recreation changes wildlife behavior      (via sciencedaily.com) 

Even without hunting rifles, humans appear to have a strong negative influence on the movement of wildlife. A study of Glacier National Park hiking trails during and after a COVID-19 closure adds evidence to the theory that humans can create a 'landscape of fear' like other apex predators, changing how species use an area simply with their presence. Researchers found that when human hikers were present, 16 out of 22 mammal species, including predators and prey alike, changed where and when they accessed areas. Some completely abandoned places they previously used, others used them less frequently, and some shifted to more nocturnal activities to avoid humans.

New modelling shows how interrupted flows in Australia's Murray River endanger frogs      (via sciencedaily.com) 

Flooding in Australia's Murray-Darling Basin is creating ideal breeding conditions for many native species that have evolved to take advantage of temporary flood conditions. Scientists have now developed virtual models of the Murray River to reveal a crucial link between natural flooding and the extinction risk of endangered southern bell frogs (Litoria raniformis; also known as growling grass frogs). Southern bell frogs are one of Australia's 100 Priority Threatened Species. This endangered frog breeds during spring and summer when water levels increase in their wetlands. However, the natural flooding patterns in Australia's largest river system have been negatively impacted by expansive river regulation that in some years, sees up to 60% of river water extracted for human use.
