The role of connectivity in the interplay between climate change and the spread of alien fish in a large Mediterranean river
Dams exacerbate the consequences of climate change on river fish: A potential response of river fish to environmental changes is to colonise new habitats. Dams restrict the habitats of fish, but do not necessarily prevent the spread of invasive species, as Johannes Radinger and his team found.
Pragmatic animal welfare is independent of feelings
In this Letter to Science the researchers argue that effective application of animal welfare in conservation is also possible if it is based on objective and measurable parameters of animal welfare – without relying on concepts such as consciousness, sentience or pain.
Knowledge gaps and management priorities for recreational fisheries in the developing world
A survey with fisheries experts to gather information on recreational fisheries in developing countries shows that recreational fishing is socially important and is expected to grow in most countries. Recreational fisheries were described as mainly consumption oriented. Most often, tourists use marine waters, whereas resident recreational fishers use fresh waters.
The sterlet sturgeon genome sequence and the mechanisms of segmental rediploidization
Researchers have succeeded in sequencing the sturgeon genome, delivering a missing piece of the puzzle essential to understanding the ancestry of vertebrates. The genetic material of the sterlet has undergone very little change over the past 300 million years or more.
