Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Biology of the amphipod Gammarus pulex L. in water-bodies of the Leningrad district, and its piscicultural importance [Translation from: Trudy Vsesoyuznogo Gidrobiologicheskogo Obshchestva 7 99-122, 1956] [PDF]

, 1977
Observations and laboratory experiments are summarised that examine the widely discussed issue of what Gammarus pulex feeds on. On the basis of the observations of the authors and data from the literature it can be noted that G.

Between the Sheets: CH3SO3H Molecules Intercalating B2O3 Layers

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The intercalation compound B6O9·CH3SO3H can be seen as the stabilization of a new B2O3 modification by methanesulfonic acid. The structure elucidation was performed by X‐ray diffraction and solid‐state NMR measurements. The reaction of boric acid and methanesulfonic acid yielded single crystals of B6O9·CH3SO3H (monoclinic, I2/a, Z = 8, a = 873.19(3), b

Věřit znamená vidět. Biologie jako ideologie

Sociální studia, 2016
Text objasňuje mechanismy používané k legitimizaci genderových rozdílů skrze biologii, stejně jako epistemologický omyl sociálních a biologických věd s ohledem na současný výzkum o genderových rozdílech. Četné příklady ukazují skryté nerovnosti, jež jsou

Critical evaluation of three cryo‐EM structures of particulate methane monooxygenase by quantum refinement

Acta Crystallographica Section D, EarlyView.
We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.

Réductionnisme, holisme et émergentisme [PDF]

, 2014
National audienceL’objectif principal de ce chapitre est de distinguer entre deux formes de réductionnisme possibles en Biologie, de sorte à mieux comprendre les enjeux du débat contemporain à ce sujet. En effet, une attitude réductionniste au sein de la
