A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.
Stink-flirting among ring-tailed lemurs come at a cost, but may also influence females in choosing a mate.
When seeking a cure for a disease, early detection is often the key. The same is true for eliminating invasive species. Identifying their presence in a lake before they are abundant is vital. A recent University of Illinois study successfully used environmental DNA to detect invasive clams in California and Nevada lakes. Researchers believe this tool can help identify pests before they become a problem.
An increasingly catholic diet among European shags at one of Scotland's best-studied breeding colonies has been linked to long-term climate change and may have important implications for Scotland's seabirds.
Leipzig. Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. In addition, forest managers do not have to decide on the provision of solely one function, such as wood production or nature conservation: several services provided by forest ecosystems can be improved at the same time. These are the results of two studies led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in Ecology Letters.
Using wide-ranging eDNA analysis combined with traditional collection survey methods, Japanese researchers have identified the breeding site of critically endangered fish species Acheilognathus typus in the mainstream of Omono River in Akita Prefecture, Japan. The findings were published on November 14 in the online edition of The Science of Nature - Naturwissenschaften.
New technique provides deeper look at microbial communities by assessing their biomass.
Scientists working in the vanguard of new genetic technologies have issued a cautionary call to ensure that possible applications in conservation will only affect local populations. In an article publishing Nov. 16 in the open-access journal PLOS Biology, Neil Gemmell from the University of Otago, New Zealand, and Kevin Esvelt of MIT examine the possible consequences of the accidental spread of existing self-propagating gene drive systems.
A new review article presents evidence that argues for a more nuanced approach to the design of global-change experiments -- one that acknowledges and purposefully incorporates the variability inherent in nature.
The hypothesis assumes that an entirely new gene is produced from the non-stop frame on the antisense strand of a GC-rich gene after gene duplication, followed by the accumulation of base substitutions to produce a mature novel GC-rich gene.
