Breeding trouble: Meta-analysis identifies fishy issues with captive stocks

Tue, 13 Mar 18 00:13:30 -0700

A meta-analysis has found patterns that may be jeopardising the long-term success of worldwide animal breeding programs, which increasingly act as an insurance against extinction in conservation, and for food security. Captive-born animals had, on average, almost half the odds of reproductive success compared to their wild-born counterparts in captivity; in aquaculture, the effects were particularly pronounced. The Sydney-based scientists were surprised by how universal the patterns were across the animal kingdom.

Pterosaurs went out with a bang, not a whimper

Fossils of six new species of pterosaurs -- giant flying reptiles that flew over the heads of the dinosaurs -- have been discovered by a research team led by the Milner Centre for Evolution at the University of Bath, revealing that this lineage was killed off in its prime. An analysis of the fossils, publishing March 13 in the open-access journal PLOS Biology shows that, contrary to previous studies, there was still remarkable diversity among pterosaurs up to the point of their extinction.

Climate change risk for half of plant and animal species in biodiversity hotspots
Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2
