Increased NPY mRNA would be consistent with increased appetite in fasted birds, and increased AGRP, an antagonist to α MSH for MC4R, would be consistent with reduced metabolic rate in fasted chicks.
Standing burned trees and shrubs were used as natural perches by frugivorous birds and increased seed arrival into recently burned communities.
The abstract of the article Wild Birds and Increased Transmission of Highly Pathogenic Avian Influenza (H5N1) among Poultry, Thailand (Juthatip Keawcharoen et al).
Mulberry leaves, owing to their high carotene content, can form a valuable source of vitamin A for the health of poultry birds and increased egg production.
Exponentiation of the coefficient for the continuous variables represents the increase in the risk of Campylobacter as the median flock size increased by 1,000 birds, and the increase in risk for each additional house on the farm (see discussion).
The richness of both birds and bats increased with an increase in the proportion of native plants, bird species richness increased with increasing volume of understorey vegetation, and increasing large tree density led to increased bat activity.
The predicted effect of immunity (or cross-immunity) is a decline in the proportion of susceptible birds and an increase in the proportion of recovered and resistant birds as LPAI viruses spread in the population during fall migration.
The circulation of avian H2 strains in domestic birds and pigs increase the risk of human exposure to these viruses and reintroduction of the viruses to the human population.
By their presence and obstinacy, birdwatchers affect the attractiveness of the breeding, migration or roosting sites for birds, flush birds, and otherwise increase the pressure on birds and their habitats (e.g., luring birds out of their hideouts and stressing them by playing their calls or exposing birds and their nests to predators).
Greater vertical complexity found in fennel communities, which increased visitation by frugivorous birds and likely increased native seed dispersal, may have been responsible for the increase in native species richness in the untreated areas.
