After a two-and-a-half-year expedition through the world's most biodiverse protected area, the Identidad Madidi explorers have concluded their epic quest of completing a massive biological survey of Madidi National Park, uncovering more than 120 potentially new species of plants, butterflies and vertebrates in the process, according to WCS (Wildlife Conservation Society).
Researchers at the University of New Hampshire have found that changes in the seascape may impact the behavior of fish and could be leaving them less options for refuge and more vulnerable to predators.
A group of researchers has published the first study to determine the prevalence of twin births and chimerism in a large population of PRE horses, and the results suggest that chimerism is not especially connected to infertility.
In November 2017 -- under a biodiversity monitoring and assessment activity supported by the US Agency for International Development -- scientists and conservationists of the Leibniz Institute for Zoo and Wildlife Research and WWF-Vietnam captured photographs of one of the rarest and most threatened mammal species of Southeast Asia, the large-antlered muntjac, in Quang Nam province, central Vietnam.
During embryonic development genetic cascades control gene activity and cell differentiation. In a new publication of the journal PNAS, the team of Ulrich Technau of the Department of Molecular Evolution and Development at the University of Vienna reported that besides the genetic program, also mechanical cues can contribute to the regulation of gene expression during development. Comparisons with other animals suggests that this regulatory principle is ancient.
Corals growing in high-latitude reefs in Western Australia can regulate their internal chemistry to promote growth under cooler temperatures, according to new research at the ARC Centre of Excellence for Coral Reef Studies at The University of Western Australia. The study, published today in Proceedings of the Royal Society B, suggests that ocean warming may not necessarily promote faster rates of calcification in reefs where temperatures are currently cooler (lower than 18C).
The many threats facing bumblebees can be tested using a 'virtual safe space' created by scientists at the University of Exeter.
A new study of how ligaments restrict joint movement suggests that pterosaurs and 'four-winged' dinosaurs couldn't have flown in the same way that bats do.
One of the consequences of globalization is the introduction of invasive species. Giant hammerhead flatworms, or land planarians, up to 40 cm (over 1 foot) in length, are reported from France and overseas French territories by an international team led by Jean-Lou Justine of ISYEB (Muséum National d'Histoire Naturelle, Paris, France). This is the first study of this invasion, reported in an article to be published in the open-access journal PeerJ.
Using museum specimens and fossil records, researchers have produced a comprehensive (and unprecedented) range history of coyotes that can help reveal the ecology of predation as well as evolution through hybridization.
