Climate change will result in some areas becoming warmer and others cooler, and will amplify the magnitude of year-to-year thermal variation in many areas. How will such changes affect animals that rely on ambient thermal heterogeneity to behaviourally regulate their body temperatures? To explore this question, we raised 43 captive-born tiger snakes Notechis scutatus in enclosures that provided...

The rapid expansion of oil and natural gas development across the Northern Great Plains has contributed to habitat fragmentation, which may facilitate brood parasitism of ground-nesting grassland songbird nests by brown-headed cowbirds (Molothrus ater), an obligate brood parasite, through the introduction of perches and anthropogenic edges. We tested this hypothesis by measuring brown-headed co...

Five new species of the feather mite genus Passeroptes (Acariformes: Dermationidae) are recorded from birds of the order Passeriformes in China: P. lioparis sp. nov. from Chrysotus chrysotis (Blyth) (Paradoxornithidae); P. motacillae sp. nov. from Motacilla cinerea Tunstall (Motacillidae); P. cyanodermae sp. nov. from Cyanoderma ruficeps Blyth (Timaliidae); P. periparus sp. nov. from Periparus ...

A total of 16 genera and 68 species of Chalcididae of Vietnam are taxonomically treated. Thirteen new species are described; the remaining 55 species are keyed, redescribed or provided with a diagnosis. Among these 37 species and eleven genera are recorded for the first time from Vietnam. The thirteen new species are: Antrocephalus neogalleriae Narendran & van Achterberg, sp. n.; Brachymeria ne...

ABSTRACT: One of the biggest challenges in intercropping two or more crops is to maintain their productivity as that sole counterparts. In order obtain sustainable systems a semi-arid environment, this study evaluated agro-economic advantage and sustainability intercropped carrot cowpea, optimizing green manuring spatial arrangements. Experiments were conducted period from July October 2017 201...

In mammals, episodic memory and spatial cognition involve context-specific recruitment of unique ensembles in the hippocampal formation (HF). Despite their capacity for sophisticated spatial (e.g., for migration) and episodic-like (e.g., for food-caching) memory, the mechanisms underlying contextual representation in birds is not well understood. Here we demonstrate environment-specific Egr1 ex...

Measurements of the self-diffusion coefficient in supercooled ~ater to 300 MPa are reported. Translational diffusion in liquid water at 243 K is enhanced by 60% when the pressure is increased from 0. 1 to 150 MPa, and rotational diffusion is enhanced by almost 250% between 0. 1 and 250 MPa. These striking anomalies are interpreted in terms of the proximity of a conjectured line of spinodal-like...
