Description of the karyotypes of Stejneger's beaked whale (Mesoplodon stejnegeri) and Hubbs’ beaked whale (M. carlhubbsi)

Genetics and Molecular Biology, 2017
The genus Mesoplodon (Cetacea: Odontoceti: Ziphiidae) is one of the few cetacean genera with the karyotype 2n = 42. The 2n = 42 karyotype of M. europaeus and M.

Challenges of Monitoring Endangered Bryde's Whales During a Period of Rapid Environmental Change

Animal Conservation, EarlyView.
Estimating population size is challenging for rare and elusive species that occur at low densities and are difficult to detect during sampling. We estimated the abundance of a Nationally critical whale species—Aotearoa New Zealand Bryde's whales—using a custom‐formulated POPAN model which incorporated transience to account for their complex residency ...

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Multi‐event modeling of Hector's dolphin (Cephalorhynchus hectori) fecundity using four decades of monitoring: Implications for current management of bycatch

Conservation Science and Practice, EarlyView.
Updated estimate of fecundity for Hector's dolphin is lower and more precise than prior estimation. This latest estimate suggests a lower capacity for population growth than previously thought and a reduced resilience to anthropogenic threats. Abstract Prediction of future population trajectories is vital in the management of threatened species but ...

Beyond area: Evaluating Australia's contribution to Aichi Target 11 and implications for 30 × 30

Conservation Science and Practice, EarlyView.
Australia has expanded its land‐based protected areas significantly between 2010 and 2022, increasing overall coverage from 12.1% to 22.3% and improving the protection of intact landscapes. However, progress on key biodiversity metrics—such as threatened species coverage and bioregional representation—has been limited, with many species and regions ...

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Repatterning of mammalian backbone regionalization in cetaceans

Nature Communications
Cetacean reinvasion of the aquatic realm is an iconic ecological transition that led to drastic modifications of the mammalian body plan, especially in the axial skeleton. Relative to the vertebral column of other mammals that is subdivided into numerous

Revisiting Indonesia’s governance and conservation of cetaceans

iScience
Summary: Over the past few decades, Indonesia’s marine conservation governance has been criticized. This article analyzes the overlaps and gaps in domestic law and policy regimes for cetaceans or marine mammal management and examines issues of ...
