Humans found to prey on approximately one-third of all vertebrate species
An international team of ecologists, life scientists, conservationists and biologists has found that humans prey on approximately one-third of all vertebrate species in existence. In their study, reported in the journal Communications Biology, the gr.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Stem carbohydrate richness in two cycad species
Terrestrial plants have developed strategies to cope with suboptimal conditions. Storage of nonstructural resources is one of those strategies. Nonstructural carbohydrates (NSCs) of plants are primarily sugars and starch, and have been studied extens.....»»
Pathogenic system found on Providencia rustigianii has virulence gene akin to Salmonella"s

Microbiome studies in humans and zoo animals pave the way for new drug development
Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health......»»
DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
Aquaculture could harm animal welfare or protect it, depending on what species the farms raise
The global aquaculture industry has tripled in size since the year 2000, with producers raising a mind-boggling diversity of species, from seaweeds and clams to carp, salmon and cuttlefish. Many of these creatures are undomesticated and lead complex.....»»
Humans have near-equal numbers of male and female babies, unlike many other animals—a new genetic study looks for clues
We know that boys and girls are produced in much the same frequency. But how—and why—is this 1:1 ratio achieved?.....»»

From Northern Germany to Italy in five days: Tiny transmitters provide insights into precise migration routes of bats
Some bat species are among the world champions of seasonal migration in the animal kingdom. Leisler's bat, for example, which weighs between 12 and 22 grams, flies from central or Eastern Europe to the Mediterranean every late summer—and back in sp.....»»
Global study shows causes for the dominance of woody plants in drylands
Precipitation, temperature, and grazing have the greatest influence on whether woody or herbaceous species grow in dryland areas. This has been shown by a large global study that includes Potsdam researchers......»»
