Genetic Associations of Functional Longevity With Sexual Precocity and Growth Traits in Nellore Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Functional longevity (FL) is a complex trait that integrates many attributes directly contributing to the successful retention and productivity of a cow within the herd. Consequently, improving FL in beef cattle increases herd profitability. This study aimed to estimate the genetic associations between two alternative FL definitions and traits

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Conversion Practices in Eating Disorder Treatment: A Lived Experience Narrative

Journal of Psychiatric and Mental Health Nursing, EarlyView.
ABSTRACT Background and Aim Conversion practices (sometimes referred to as ‘conversion therapy’) refer to interventions that aim to change a person's sexual orientation or gender identity. While these are often associated with faith‐based settings, they can also occur in secular healthcare contexts.
