Juvenile-hormone-mediated plasticity of aggregation behaviour and olfactory processing in adult desert locusts [Elektronisk resurs]

, 2001
In desert locusts Schistocerca gregaria, aggregation behaviour is elicited by aggregation pheromones. In this study, we show that the behavioural response to the major and most potent adult aggregation pheromone component, phenylacetonitrile, is age- and

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Cortisol concentrations in hair are biomarkers of health status and seasonal change, but not urbanisation, in wolves

Wildlife Biology, EarlyView.
Wolves have reclaimed much of their former range in Europe, including areas with a high human footprint, yet the physiological impacts of human‐associated stressors remain poorly understood. We first examined methodological factors affecting hair cortisol concentrations (HCC) in wolves by using a ‘shave/re‐shave' design to assess hair growth rate and ...

Juvenile hormone role on metabolic switch during immune-response

, 2019
The role of Juvenile hormone during immune response was investigated in Drosophila melanogaster larvae. The levels of Juvenile hormone were measured directly by mass spectrometry and indirectly by monitoring Krüppel Homologue expression. Neither of those

Seasonal variation in faecal glucocorticoid metabolite concentrations of two dominant southern African murids (Lemniscomys rosalia and Mastomys coucha) across variously transformed landscapes

Wildlife Biology, EarlyView.
Global landscape transformations are a result of a growing human population and the subsequent increased use of natural habitats. Local species extinctions across various transformed landscapes emphasise the importance of monitoring wildlife responses to anthropogenic activities.

Juvenile hormone activity in Dysdercus cingulatus Fabr by juvenile hormone esterase inhibitor, OTFP

, 2007
901-906Application of juvenile hormone esterase inhibitor 3-octylthio-1,1,1- trifluropropan-2-one (OTFP) to 5th instar nymphs and virgin females of D. cingulatus revealed the profound role played by juvenile hormone esterase (JHE) in metamorphosis and ...

Assessing the Influence of Interference Competition on Ecologically Similar Species Threatened by Habitat Loss 评估干扰性竞争对受栖息地丧失威胁的生态相似物种的影响

Wildlife Letters, EarlyView.
We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

Life history attributes influencing metabolic variation in an estuarine fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Considering that energy availability and oxygen transport potential are limited in supplying metabolic requirements, all animals face trade‐offs between competing metabolic demands.
