A meta-analysis of nearly 300 studies of soil biodiversity in Amazonian forests found that the abundance, biomass, richness and diversity of soil fauna and microbes were reduced following deforestation.
A new Duke University-led study finds that the loss of marsh-edge salt grasses and mangroves due to disturbances such as heavy oiling from the 2010 Deepwater Horizon oil spill doubles the rate of shoreline erosion in hard-hit marshes.
Determining how one species becomes distinct from another has been a subject of fascination dating back to Charles Darwin. New research led by Carnegie's Matthew Evans and published in Nature Communications elucidates the mechanism that keeps maize distinct from its ancient ancestor grass, teosinte.
Preventing the introduction of the mosquitofish and removing its population are the most effective actions to control the dispersal of this exotic fish in ponds and lakes, according to a study published in the journal Science of the Total Environment.
Crabs from a single species rely on different camouflage techniques depending on what habitat they live in, new research shows.
From the urban jungle -- even the leafier parts of suburbia -- we often have a tough time naming the last plant we saw. Even if we just ate part of it. This is a symptom of 'plant blindness,' a term coined two decades ago by researchers who showed that people are perilously disconnected from the plant kingdom. This has progressed to the point where we hardly recognize the plants that feed us every day.
Using paper stickers to collect pathogens on surfaces where antisepsis is required, such as in food processing plants, is easier, and less expensive than swabbing, yet similarly sensitive. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Photosynthesis makes our atmosphere oxygen-rich and forms the bedrock of our food supply. But under changing or stressful environmental conditions, the photosynthetic process can become unbalanced, resulting in an excess of highly reactive oxygen molecules that could cause cellular damage if they aren't neutralized. New work explores how the photosynthetic algae Chlamydomonas shields itself from this potential danger.
A team of researchers from Tokyo University of Science, Meiji University, and Tokyo University of Agriculture and Technology, led by Professor Takayuki Arazoe, has recently established a series of novel strategies to increase the efficiency of targeted gene disruption and new gene 'introduction' using the CRISPR/Cas9 system in the rice blast fungus Pyricularia (Magnaporthe) oryzae.
Fish on coral reefs manage to thrive in isolated areas where there are very low levels of nutrients for them to use. How? The answer may lie in the tiny fish that live in the gaps in the coral structure.
