TL;DR: Interordinal comparisons of least squares regressions of log-transformed BMR and mass suggest that the Insectivora have a significantly steeper slope to their allometric relationship than do most other orders, while the non-insectivore orders are statistically homogeneous with respect to slope.

TL;DR: Changes in the adherence, opsonization, phagocytosis, nitroblue tetrazolium reduction and antibody-dependent cell cytotoxicity of peritoneal macrophages were observed with aging in BALB/C mice.

TL;DR: A competition for binding sites on the gill between Ca and other divalent or trivalent metallic ions influences their uptake and toxicity to fish.

TL;DR: The activity peak of liver lipase-esterases suggests active lipid metabolism in mid-summer only and the histological structure of liver followed the glycogen dynamics, which suggested haemopoetic tissue with structures like thyroid follicles enclosed in spring.

TL;DR: While freshwater turtles are often reputed to overwinter buried in mud, which is an anoxic microenvironment, this behaviour seems unlikely for southern Trionyx and Sternotherus, although it may be possible for northern Chrysemys.

TL;DR: The fractional protein synthesis rate (FSR) of tissue (liver, digestive tract, muscle and whole fish) proteins was measured in rainbow trout acclimated to 9 and 18 degrees C after a pulse injection of [U-14C] L-leucine.

TL;DR: Under natural conditions song may be an important stimulus to ovarian development on both the wintering and breeding grounds in White-crowned Sparrows exposed to various photoperiods and to tape-recorded male song.

TL;DR: Cooling curves of dead little brown bats were used to generate values of conductance and insulation under a variety of conditions, and small wooden cavities provided 28% more total insulation to solitary bats than did a large cavity.

TL;DR: The relative gonadal index, RGI, was found to be more appropriate than the gonosomatic index for all three species and was tested using ovaries of three ecologically distinct fish species.

TL;DR: It is concluded that alterations in both plasma volume and osmolarity, which may occur during hypohydration, play a major role in the alteration in thermoregulatory responses during hyphydration.

TL;DR: The majority of measured variables attained a stable level within 3 hr, exceptions being pH and lactate, however, it is argued that even after 24 hr post-operation the fish were in a “stressed” condition.

TL;DR: Blood from capture-stressed striped marlin cannot be fully saturated with oxygen in the presence of lactic acid because of a substantial Root effect, and the O2 transport properties of the blood are discussed in relation to oxygen demand and capture stress.

TL;DR: It is concluded that juvenile alligators are unable to survive chronic exposure to hyperosmotic salinities.

TL;DR: A higher rate of metabolism in both the mother and her offspring may synergistically permit aHigher rate of conversion of maternal food into offspring tissue and the potential ecological significance and organismic consequences of interspecific differences in metabolic rate are briefly discussed.

TL;DR: Blood chemistry changes caused by food-stress was measured in fledgling herring gulls and significant decreases were found in the concentrations of 14 of the 26 free amino acids studied.

TL;DR: The osmolality and concentrations of Na, K, Cl and the hormones arginine vasotocin (AVT), prolactin, aldosterone and corticosterone were measured in plasma as functions of time in relation to oviposition, changing NaCl content of the diet, and feeding-inanition.

TL;DR: The Bedouin goats are capable of maintaining during 3 days of dehydration a level of consumption which is well above their maintenance requirements while the Saanen goats consumed only the amount of feed which is needed to satisfy their Maintenance requirements.

TL;DR: The role brown fat, and the effects of impairments in its function, are described in relation to thermoregulation and the control of energy balance and body composition.

TL;DR: Both species produced two types of pellets,one nitrogen-rich intended for caecotrophy, and one nitrogen-poor delivered as faecal pellets, and both produced labelled bacteria infused into the proximal colon of guinea-pigs transported in the furrow into the caecum.

TL;DR: Resting oxygen consumption corrected for body size, increased in young marsupials (Bennett's Wallaby) with body weights of 50-400 g, which corresponded to a rapid increase in growth rate and identification of active brown adipose tissue.

TL;DR: This review is concerned with how bird embryos breathe, mainly the domestic fowl, and the ontogeny and mechanism of gaseous exchange can in general terms be applied to most birds.

TL;DR: It seems that SW adaptation of rainbow trout modifies Na intestinal absorption principally in its posterior part and in relation with the Na+, K+-ATPase activity.

TL;DR: Oxygen consumption as well as heart rate increased with rising temperature, but these values for 10°C-acclimated fish were higher in comparison with those for 25°C -ac Climated fish.

TL;DR: Palaemon elegans behaves as a strong oxyregulator under hyperoxic and hypoxic conditions and exhibits periods of cardiac arrest and cessation of ventilatory activity, the duration of which increased as the ambient oxygen tension increased.

TL;DR: A relationship was found between flying activity and organ weight, blood volume and hematocrit and no significant differences were found in the O2 carrying capacity of hemoglobin in these birds.

TL;DR: Electrophysiological and ultrastructural analysis of rat hippocampal slices incubated in the chamber showed that its two compartments allows performance of reliable paired comparison studies in a highly efficient manner.

TL;DR: Glyoxylic acid-induced fluorescence in whole-brain preparations of the central nervous system of the freshwater pond snail, Lymnaea stagnalis, was used to map the distribution of serotonin-and dopamine-containing neurons.

TL;DR: A fishmeal-based reference diet, a soybean-yeast-based methionine (MET)-deficient diet and two MET-supplemented diets were fed to groups of yearling sea-bass, reared in sea-water at 21 +/- 1 degrees C as mentioned in this paper.
