The capelin, Mallotus villosus (Osmeriformes, Osmeridae), is an ecological and commercial key component of the sub-arctic ichthyofauna. Here, we provide the first cytogenetic information on the species based on both conventional karyotyping and ...

Utilizing Environmental DNA Metabarcoding to Assess Fish-Based Food Resources in Key Foraging Areas of the Black Stork. [PDF]
This study employed environmental DNA (eDNA) to assess fish‐based food resources in key foraging areas of the Black Stork (Ciconia nigra)—Zhanghe Canyon and Qixi River National Wetland Parks in Henan, China. Results show that the main prey in these habitats are fish from the orders Siluriformes, Cypriniformes, and Perciformes, with no significant ...

Morphological covariates of the ontogenetic shift from nauplii to copepodite prey in larval fish. [PDF]
Abstract Larval fish are active planktonic predators, with many species feeding initially on copepod nauplii and gradually shifting their selection to copepodites. This study evaluated whether it is possible to develop a general widely applicable empirical model to describe the transition from feeding on copepod nauplii to copepodites in relation to ...

The content of trace elements in the Pacific capelin Mallotus catervarius (Pisces: Osmeridae) from the coastal waters of the southwestern part of Sakhalin Island [PDF]
The content of Fe, As, Cu, Mn, Cr, Ni, Pb, Hg and Cd in the muscles and gonads of the Pacific capelin sampled in 2020 in the coastal waters of the southwestern part of Sakhalin Island was estimated.

The Windy City Rookery: Movement and Activity Patterns of Black-Crowned Night Herons (<i>Nycticorax nycticorax</i>) in a Human-Dominated Landscape. [PDF]
Black‐crowned night herons (BCNH) are a cryptic, widely distributed colonial wading bird. Despite showing regional declines in North America, this species has successfully adapted to colonize urban areas. In this study, our team used GPS/GSM transmitters to explore the space use, habitat use, and diel activity patterns of BCNH breeding at the largest ...

Evaluating ecosystem caps on fishery yield in the context of climate stress and predation. [PDF]
Abstract Ecosystem‐based fisheries management strives to account for species interactions and ecosystem processes in natural resource management and conservation. In this context, ecosystem‐wide caps on total fishery catches have been proposed as one tool to manage multispecies fisheries with an ecosystem approach.

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding. [PDF]
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...
