Winterkill lakes often have a characteristic fish community, presumably composed of species able to survive winter hypoxia. Our research on a small winterkill lake in northern Wisconsin indicates that fishes common in winterkill lakes have behavioral adaptations for tolerating or avoiding winter hypoxia...
Prairie dogs have many adaptations like sharp claws to help it dig their burrows. They have sharp hearing so they can hear if a predator is coming. Prairie Dogs have whiskers that they use for balance so when they walk they won't fall over. The thick, dense coats of a sloth help keep...
and die, but variable individuals interrelated to each other and able to maximize their lifetime reproductive success by an adaptive behavior. Behavioral adaptations of these individuals can be to some degree predicted by the Darwinian theory ofnatural selection, while the close analysis of the habita...
The giant squid, which can get as big as 70 feet long when most squids top out a 12 inches, is attached to many myths. In truth, giantsquid adaptationsarose to allow it to survive and thrive in the deep ocean where light is very limited. Giant Squid Size The giant squid size could ...
At what depths or times of day they feed on marine snow-associated materials is unclear. The extreme transparency of leptocephali and use of shape-change behaviors or expandable chromatophores along with their gut swellings or external appendages may be adaptations for reducing predation rates ...
In a climate-change context, the survival of macrofauna is related to their adaptation potential, including genetic variation and phenotypic/behavioral plasticity (O'Connor et al., 2012). Behavioral adaptations of macrofauna to the sandy beach habitat have been subjected to a large amount of ...
These fish have special adaptations, such as sharp eyes and a powerful tongue, to help them get a tasty dinner almost every time. Some animals use their speed to catch prey. For example, cheetahs can run 70 miles per hour (113 km/h), which is faster than any of the animals they ...
even in taxa without an assembled genome. The large mutational target hypothesis also predicts a greater birth rate of neurogenic genes in species that have evolved new complex behavioral adaptations such as gene family expansions of neuronally-expressed protocadherins and C2H2 zinc-finger transcription...
Declining Arctic sea ice is increasing polar bear land use. Polar bears on land are thought to minimize activity to conserve energy. Here, we measure the daily energy expenditure (DEE), diet, behavior, movement, and body composition changes of 20 differe
Although behavio- ral sensitization is not tantamount to craving, it is often thought to induce compensatory homeostatic or incen- tive-motivational adaptations which, in turn, could incu- bate craving or "pathological wanting" that may be rekindled by stress or drug cues during prolonged absti...
