The effect of radiation on seedling growth and physiology in four species of Prosopis L. (Mimosaceae)
(Academic Press Ltd - Elsevier Science Ltd, 2000-11)
Domestication of wild plants needs efforts focused particularly on the development of the theoretical basis of plant responses to environmental conditions. The objective of this study was to assess the effect of radiation ...
Reproducibility in the response of soil bacterial community-level physiological profiles from a land use intensification gradient
(Elsevier Science, 2004-05)
This work assessed soil bacterial diversity through community-level physiological profiles (CLPP) over three consecutive years, at sites representing a gradient of land use intensification. The relationship between CLPP ...
Does land use change alter water and nutrient dynamics of phreatophytic trees in the Central Monte desert?
(John Wiley & Sons Inc, 2016-07)
In the woodlands of the Central Monte desert (Argentina), phreatophyte vegetation is exposed to different levels of disturbance. Livestock and settlement activity produce mainly nutrient inputs and partial vegetation ...
Interaction between hydrogen sulfide and hormones in plant physiological responses
(Springer, 2019-01)
The gasotransmitter, hydrogen sulfide (H 2 S) is involved in plant growth and development, and stress responses. Plant hormones influence the levels of endogenous H 2 S and H 2 S may affect the biosynthesis, transport, and ...
Long-term starvation and posterior feeding effects on biochemical and physiological responses of midgut gland of Cherax quadricarinatus juveniles (Parastacidae)
(Public Library of Science, 2016-03)
We investigated the effect of long-term starvation and posterior feeding on energetic reserves, oxidative stress, digestive enzymes, and histology of C. quadricarinatus midgut gland. The crayfish (6.27 g) were randomly ...
Differential antipredatory responses in the tuco-tuco (Ctenomys talarum) in relation to endogenous and exogenous changes in glucocorticoids
(Springer, 2019-11)
Glucocorticoids participate in the behavioral and physiological responses generated under stressful circumstances coming from different sources—physical and/or psychological. In mammals, the increases of these hormones are ...
Effects of the heavy metals Cu2+, Ni2+, Pb2+ and Zn2+ on some physiological parameters of the lichen Usnea amblyoclada to air pollutants
(Academic Press Inc Elsevier Science, 2007-12)
The effect of Cu2+, Ni2+, Pb2+, and Zn2+ on some physiological parameters of the lichen Usnea amblyoclada and the selective uptake of Cu2+ and Pb2+ was assessed. Fresh thalli were soaked in single or mixed metallic solutions. ...
Sedative and physiologic effects of tiletamine–zolazepam following buccal administration in cats
(Elsevier, 2019-02)
Objectives: The aim of this study was to describe the sedative and some physiological effects of tiletamine?zolazepam following buccal administration (BA) in cats. Methods: Seven healthy spayed European Shorthair cats ...
Ecotourism effects on health and immunity of Magellanic penguins at two reproductive colonies with disparate touristic regimes and population trends
(Oxford University Press, 2018-11)
Negative effects of ecotourism on wildlife are rising worldwide. Conservation physiology can play a major role in protecting wildlife by providing early alerts on changes in the status of individuals exposed to tourist ...
Behavioural and respiratory response of the shallow-water hermit crab Pagurus cuanensis to hydrostatic pressure and temperature
(Elsevier Science, 2010-04)
The evolutionary history of the Anomura has long been controversially discussed. One aspect that has received little attention is the dissimilarity in physiological tolerances of the related families Paguridae and Lithodidae ...
