Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

Entomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

Entomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Polymorphism of BGN gene (g.77807325 G>C) and its association with fatty acid and carcass characteristics of Indonesian meat lamb

Journal of the Indonesian Tropical Animal Agriculture
Fatty acid content and carcass characteristics are two meat quality traits consumers choose to ob tain healthy and high-quality lamb. Genetic improvement of fatty acid content and carcass characteris tics in sheep is important to increase the public ...

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

Ibis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.

Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.
