Potential of pest regulation by insectivorous birds in Mediterranean woody crops.

PLoS ONE, 2017
Regulation of agricultural pests managing their natural enemies represents an alternative to chemical pesticides. We assessed the potential of insectivorous birds as pest regulators in woody crops located in central Spain.

Blood lead levels in Bald Eagles (Haliaeetus leucocephalus) in Southeast Alaska by gender and capture location. [PDF]

, 2014
Research into the effects of lead on bald eagles has demonstrated that lead levels are higher in bald eagles than other birds at lower trophic levels (Burger and Gochfield 2009).

Using life-history traits to explain bird population responses to changing weather variability [PDF]

, 2011
Bird population dynamics are expected to change in response to increased weather variability, an expression of climate change. The extent to which species are sensitive to effects of weather on survival and reproduction depends on their life-history ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Phenotypic constraints at the top of the world: an Arctic songbird faces the cumulative cost of maintaining a winter-like phenotype during breeding

Frontiers in Ecology and Evolution
Among birds, several body composition traits typically decrease in size or mass during breeding likely as a result of competing demands during this critical life history stage. However, a recent outdoor captive study in an Arctic-breeding cold-specialist

Scientific Opinion on the safety and efficacy of Natugrain® TS (endo‐1, 4‐beta‐xylanase and endo‐1, 4‐beta‐glucanase) as a feed additive for chickens reared for laying, turkeys for breeding purposes, turkeys reared for breeding, other minor avian species (other than ducks) and ornamental birds

EFSA Journal, 2011
The safety of the product was previously established in chickens and turkeys for fattening, and for laying hens. In the view of the Panel the conclusions apply to those reared for laying/breeding and for breeding hens.

The sub-annual breeding cycle of a tropical seabird.

PLoS ONE, 2014
Breeding periodicity allows organisms to synchronise breeding attempts with the most favourable ecological conditions under which to raise offspring. For most animal species, ecological conditions vary seasonally and usually impose an annual breeding ...

Urbanization and Human Population Favor Species Richness of Alien Birds

Diversity, 2020
Human activities like urbanization and agriculture affect spatial biodiversity patterns. The presence and activities of humans richly benefit alien species, but native species usually decline in human-impacted areas.

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, EarlyView.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

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 ...
