Breeding decisions and output are correlated with both temperature and rainfall in an arid-region passerine, the sociable weaver [PDF]

Royal Society Open Science, 2017
Animal reproductive cycles are commonly triggered by environmental cues of favourable breeding conditions. In arid environments, rainfall may be the most conspicuous cue, but the effects on reproduction of the high inter- and intra-annual variation in ...

Identification of cassava germplasms resistant to two-spotted spider mite in China: From greenhouse large-scale screening to field validation

Frontiers in Plant Science, 2022
IntroductionUtilization of resistant germplasm is considered as an effective, economical and eco-friendly strategy for cassava pest management. Tetranychus urticae, known as the two-spotted spider mite (TSSM), is a devastating pest in Asian cassava ...

Seasonal Pattern of Advertisement Calling and Physiology in Prolonged Breeding Anurans, Japanese Tree Frog (Dryophytes japonicus)

Animals, 2023
The calling behavior of anurans should be studied in detail as it greatly influences their physiology and immunity, particularly in prolonged breeding species. The effect can be further complicated by the emergence timing in the breeding season.

Shortening day length as a previously unrecognized selective pressure for early breeding in a bird with long parental care [PDF]

, 2014
Several different selective pressures have been suggested to explain an intense competition for early return to breeding grounds in birds. In this study we hypothesized that shortening day length during summer months may constitute additional ...

Seasonal expressions of VEGF and its receptors VEGFR1 and VEGFR2 in the prostate of the wild ground squirrels (Spermophilus dauricus)

European Journal of Histochemistry, 2021
As a vital male accessory reproductive gonad, the prostate requires vascular endothelial growth factors for promoting its growth and development. In this study, we investigated the localizations and expressions of vascular endothelial growth factor (VEGF)

Supplementary feeding increases nestling feather corticosterone early in the breeding season in house sparrows [PDF]

, 2017
Several studies on birds have proposed that a lack of invertebrate prey in urbanized areas could be the main cause for generally lower levels of breeding success compared to rural habitats.

Perturbations in growth trajectory due to early diet affect age-related deterioration in performance [PDF]

, 2015
Fluctuations in early developmental conditions can cause changes in growth trajectories that subsequently affect the adult phenotype. Here, we investigated whether compensatory growth has long-term consequences for patterns of senescence.

A bioenergetics model for estimating prey consumption by an Adélie penguin population in East Antarctica [PDF]

, 2015
Quantifying prey consumption by top predators is a crucial component of ecosystem-based management in the Southern Ocean. In this study, we developed a bioenergetics model to estimate prey consumption by a top predator, the Adélie penguin Pygoscelis ...

Integrative Analysis Provides Insights into Genes Encoding LEA_5 Domain-Containing Proteins in Tigernut (Cyperus esculentus L.)

Plants
LEA_5 domain-containing proteins constitute a small family of late embryogenesis-abundant proteins that are essential for seed desiccation tolerance and dormancy.
