Metabolic cost of osmoregulation in a hypertonic environment in the invasive African clawed frog Xenopus laevis
(Company of Biologists Ltd., 2016)
Studies of aquatic invertebrates reveal that salinity affects feeding and growth rates, reproduction, survival, and diversity. Little is known, however, about how salinity impacts the energy budget of vertebrates and ...
Evaporative water loss and dehydration during the night in hummingbirds
(2007)
Nectar-feeding birds oscillate between avoiding overhydration when they are feeding and preventing dehydration during fasts. Here, we examined how resting rates of total evaporative water loss (TEWL) and metabolic water ...
Improving the tolerance of vicia fabaagainst environmental salinity resulted from the irrigation with sea water by using k2 so4 and (nh4)2so4 as chemical osmoregulators.
(Universidad Nacional de Colombia, Facultad de Ciencias, Departamento de Biología, 2012)
Vicia faba L. was cultivated with irrigation with 5, 10, 15 and 20% (v:v) sea water. The plants were divided to three groups. The first was irrigated without treatments while the second was treated with 5 mM KNO3 and the ...
Early life experience drives short term acclimation of metabolic and osmoregulatory traits in the leaf eared mouse
(The Company of Biologists Ltd., 2017)
We studied the putative effect of early life experience on the physiological flexibility of metabolic and osmoregulatory traits in the leaf-eared mouse, Phyllotis darwini, an altricial rodent inhabiting seasonal Mediterranean ...
Effect of salinity acclimation on osmoregulation, oxidative stress, and metabolic enzymes in the invasive Xenopus laevis
(Wiley, 2020)
Aquatic animals often display physiological adjustments to improve their biological performance and hydrosaline balance in saline environments. In addition to energetic costs associated with osmoregulation, oxidative stress, ...
Terrestrial birds in coastal environments: metabolic rate and oxidative status varies with the use of marine resources
(Springer, 2018)
Life in saline environments represents a major physiological challenge for birds, particularly for passerines that lack nasal salt glands and hence are forced to live in environments that do not contain salty resources. ...
The interplay between ambient temperature and salt intake affects oxidative status and immune responses in a ubiquitous Neotropical passerine, the rufous-collared sparrow
(Elsevier Inc., 2019)
© 2019 Elsevier Inc.Physiological traits associated with maintenance, growth, and reproduction demand a large amount of energy and thus directly influence an animal's energy budget, which is also regulated by environmental ...
Osmoregulatory capacity and the ability to use marine food sources in two coastal songbirds (Cinclodes: Furnariidae) along a latitudinal gradient
(2006)
Cinclodes nigrofumosus and C. oustaleti are two closely related songbirds that inhabit the northern Chilean coast during the austral fall and winter.This stretch spans a dramatic north to south latitudinal gradient in ...
Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes: Furnariidae)
(2006)
1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...
Isolation Driven Divergence in Osmoregulation in Galaxias maculatus (Jenyns, 1848) (Actinopterygii: Osmeriformes)
(Public Library Science, 2016)
Background
Marine species have colonized extreme environments during evolution such as freshwater habitats. The amphidromous teleost fish, Galaxias maculatus is found mainly migrating between estuaries and rivers, but ...
