This was presumed to reflect activation of the pituitary-adrenal axis. Previous studies when only one hormone was assayed or when one hormone was used as a standard for total hormone concentration may require reevaluation in the light of our data. 展开 ...
Resource acquisition during juvenile stages can have long-term implications through an animal’s life [1]. In holometabolous insects, in which larvae often share resources, larval density can be a key factor influencing access to nutrients needed for larval growth and development [2]. Larval dens...
knowledge that will emerge from these studies will help overcome the current lack of information on male and female cells and animal models. It will also serve as a first step in embracing diversity in sex chromosome complement and sex hormone levels, in line with the emerging recognition that ...
Plots with good ecological substrates will be used as bird diversity enhancement areas, while the opposite will be focused on the space for human activities. We also will pay attention to the transition of levels, and reasonably reserve some plots for harmonious coexistence between humans and birds...

The gastrointestinal tract is adapted for long periods of quiescence punctuated by rapid metabolic upregulation for digestion and assimilation of large meals (sometimes, > 100% of body mass49). During digestion, pythons exhibit a tenfold increase in metabolic rate above resting levels; organ ...
Margay (Leopardus wiedii) in the southernmost Atlantic Forest: Density and activity patterns under different levels of anthropogenic disturbance This is the first multi-area study on patterns of density and activity of the margay in the Brazilian Atlantic Forest. We concluded that the margay is......
