Invasive species sound off about impending ecosystem changes      (via sciencedaily.com)     Original source 

Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing the hard-to-see physical and biological changes occurring in an ecosystem as they are beginning.

'Itinerant breeding' in East Coast shorebird species      (via sciencedaily.com)     Original source 

A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'

Lemur's lament: When one vulnerable species stalks another      (via sciencedaily.com)     Original source 

What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future      (via sciencedaily.com)     Original source 

The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.

Marine microbial populations: Potential sensors of the global change in the ocean      (via sciencedaily.com)     Original source 

Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.

East coast mussel shells are becoming more porous in warming waters      (via sciencedaily.com)     Original source 

Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.
