Night flight facilitates late breeding catch-up in a long-distance migratory seabird

Scientific Reports
Long-distance migrants must optimise their timing of breeding to capitalise on resources at both breeding and over-wintering sites. In species with protracted breeding seasons, departing earlier on migration might be advantageous, but is constrained by ...

Benefits of testing in both bio-secure and production environments in genomic selection breeding programs for commercial broiler chicken

Genetics Selection Evolution, 2018
Background A breeding program for commercial broiler chicken that is carried out under strict biosecure conditions can show reduced genetic gain due to genotype by environment interactions (G × E) between bio-secure (B) and commercial production (C ...

The disperser dilemma in cooperatively breeding birds

Journal of Evolutionary Biology, 2023
Abstract In most cooperatively breeding birds, individuals do not breed with their natal group members. In order to breed, they have either to disperse into another group or wait for an opposite-sex individual to join their group. In most of these species, females disperse more than males.

Aspects of the ecology of the black-headed gull (larus ridibundus) with comparative data on the common gull (L. canus) [PDF]

, 1987
Between 1982 and 1984, 893 Black-headed and 117 Common Gulls were trapped outside the breeding season in northeast England, and individually marked with wingtags or colour-rings.

The importance of analysis method for breeding bird survey population trend estimates

, 2009
Population trends from the Breeding Bird Survey are widely used to focus conservation efforts on species thought to be in decline and to test preliminary hypotheses regarding the causes of these declines. A number of statistical methods have been used to

A Dual‐Memory Ferroelectric Transistor Emulating Synaptic Metaplasticity for High‐Speed Reservoir Computing

Advanced Electronic Materials, EarlyView.
A CMOS‐compatible ferroelectric transistor harnesses the interplay between stable gate polarization memory and volatile non‐quasi‐static channel charge dynamics to emulate how biological synapses regulate their own plasticity. This brain‐inspired dual‐memory mechanism, realized in a single device, enables a physical reservoir computer that solves ...

Experimental evidence for density dependent reproduction in a cooperatively breeding passerine [PDF]

, 2009
Temporal variation in survival, fecundity, and dispersal rates is associated with density-dependent and density-independent processes. Stable natural populations are expected to be regulated by density-dependent factors.

Untangling the positive association of phylogenetic, functional, and taxonomic diversity with alien bird species richness

Ecosphere, 2020
Understanding the ecological mechanisms behind biological invasions remains a major focus of conservation biology and ecosystem management. Several hypotheses highlight that different facets of native biodiversity affect the establishment and spread of ...

Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with
