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.

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress

Advanced Science, EarlyView.
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

Studies on aspects of the ecology of some hole nesting birds [PDF]

, 1994
The breeding success of four species of small, hole-nesting woodland birds, die Blue, Great and Coal Tits and Pied Flycatcher utilising nestboxes was examined. Three study areas in County Durham were selected, Hamsterley Forest (largely a plantation) and

Penguins and purse-seiners : competition or co-existence? [PDF]

, 1985
Bibliography: leaves 110-124.The relationships between the pelagic purse-seine fishery and Jackass penguins (Spheniscus demersus) were investigated at Saldanha Bay, on the south-western coast of South Africa, between December 1982 and August 1983.

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 ...

StackingNet: Collective Inference Across Independent AI Foundation Models

Advanced Science, EarlyView.
ABSTRACT Artificial intelligence (AI) built on large foundation models has transformed language understanding, computer vision, and reasoning, yet these systems remain isolated and cannot readily share their capabilities. Coordinating the complementary strengths of independently developed, black‐box foundation models is essential for trustworthy ...

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 ...

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

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 ...
