Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

Role of urea and methylamines in buoyancy of elasmobranchs [PDF]
The possible role of urea and trimethylamine oxide (TMAO) in providing positive buoyancy has been examined for elasmobranch fishes. TMAO has a considerably lower density than an equimolar solution of urea, and solutions of both TMAO and urea are ...

MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...

ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Application of laser photogrammetry on C. carcharias in natural environment
Most morphometric methods of investigation used on large marine organisms are intrusive, as they involve the capture or the killing of the animal.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Integrating migratory connectivity data into the conservation of Australian sharks and rays
Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.
