Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Relative Mass of Brain- and Intestinal Tissue in Juvenile Brown Trout: No Long-Term Effects of Compensatory Growth; with Additional Notes on Emerging Sex-Differences

Fishes, 2018
This study investigated whether compensatory growth causes long-term effects in relative brain- or intestine size in a wild, predominantly anadromous, population of brown trout (Salmo trutta).

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Inferring phylogenetic structure and ancient hybridization within Salmonidae using next-generation sequencing

Frontiers in Marine Science, 2015
Phylogenetic studies focusing on Salmonidae have thus far revealed significant drawbacks to elucidate some of the interspecific relationships within the family, due to limited number of markers, conflicting phylogenetic signals and hybridization events ...

Whole‐Genome Sequencing and Resequencing of Hucho bleekeri Provides Insights into Genetic Mechanisms of Environmental Adaptation

Integrative Zoology, EarlyView.
A high‐quality chromosome‐level reference genome was constructed for Hucho bleekeri. Population structure and environmental adaptation of Hucho species were revealed by whole‐genome resequencing. ABSTRACT Salmonidae represents an important family in the study of genome evolution following genome duplication.

Movements and dispersal of brown trout (Salmo trutta Linnaeus, 1758) in Mediterranean streams: influence of habitat and biotic factors [PDF]

PeerJ, 2018
Dispersal is a critical determinant of animal distribution and population dynamics, and is essential information for management planning. We studied the movement patterns and the influence of habitat and biotic factors on Mediterranean brown trout (Salmo
