Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebratesNARA Subscribed
The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O. gorbuscha for ecosystems outside the native range are largely unknown. To investigate the impact on the de...
Integrated landscape approaches that engage diverse stakeholder groups in landscape governance are increasingly promoted to address linked social–ecological challenges in tropical landscapes. Recent research suggests that a transdisciplinary approach to landscape management can help identify common research needs, enhance knowledge co-production, guide evidence-based policy development, and harmonize cross-sectorial integratio...
Runs of homozygosity in killer whale genomes provide a global record of demographic historiesNARA Subscribed
Runs of homozygosity (ROH) occur when offspring inherit haplotypes that are identical by descent from each parent. Length distributions of ROH are informative about population history; specifically, the probability of inbreeding mediated by mating system and/or population demography. Here, we investigated whether variation in killer whale ( Orcinus orca ) demographic history is reflected in genome‐wide heterozygosity and ROH l...

Understanding the gastrointestinal physiology and responses to feeding in air‐breathing Anabantiform fishesNARA Subscribed
The Mekong Delta is host to a large number of freshwater species, including a unique group of facultative air‐breathing Anabantiforms. Of these, the striped snakehead ( Channa striata ), the climbing perch ( Anabas testudineus ), the giant gourami ( Osphronemus goramy ) and the snakeskin gourami ( Trichogaster pectoralis ) are major contributors to aquaculture production in Vietnam. The gastrointestinal responses to feeding in...
Reconstruction of the demographic and evolutionary history of populations assuming a consensus tree‐like relationship can mask more complex scenarios, which are prevalent in nature. An emerging genomic toolset, which has been most comprehensively harnessed in the reconstruction of human evolutionary history, enables molecular ecologists to elucidate complex population histories. Killer whales have limited extrinsic barriers to...
Fishes in a changing world: learning from the past to promote sustainability of fish populationsNARA Subscribed
Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, energy and goods are compromising fish populations through a variety of mechanisms, including overfishing, habitat degradation and declines in water quality. The important challenges raised by these issues ha...
Large‐scale migrations of brown bears in Eurasia and to North America during the Late PleistoceneNARA Subscribed
Aim Climatic changes during the Late Pleistocene had major impacts on populations of plant and animal species. Brown bears and other large mammals are likely to have experienced analogous ecological pressures and phylogeographical processes. Here, we address several unresolved issues regarding the Late Pleistocene demography of brown bears: (1) the putative locations of refugia; (2) the direction of migrations across Eurasia a...
Modelling the migratory behaviour of salmonids in relation to environmental and physiological parameters using telemetry dataNARA Subscribed
Advances in the field of telemetry techniques during the last few decades have greatly expanded our knowledge on migratory behaviour and provided the opportunity to obtain practically useful data for the conservation and management of salmonid populations. However, applying this information to the development of much needed population‐based migration models has been limited. Furthermore, this research has generally been restri...
