The model makes it possible to quantify some of the adaptive mechanisms for survival in semiarid habitats by comparing H. viridiflavus with anurans (H. tuberilinguis and Rana pipiens) of less stressful habitats. To minimize heat gain and maximize heat loss from the frog, the following points ...
It remains unclear which adaptations allowedR.amurensisto colonise the vast territory of its range, including parts of the extreme North. Since there are data indicating thatR.amurensiscan overwinter not only underwater but also on land, for a long time it was mistakenly assumed that this specie...
Discover frog habitats, what frogs need in order to survive, and the special adaptations that they have to meet their needs for survival in the environments they call home. What is a Frog Habitat? If you have ever been to a beach near the ocean, you probably saw a variety of sea ...
These descendants continued to evolve specialized adaptations for life underground over time, including elongated hind limbs for digging and reinforced skulls for protection against collapsing tunnels. Appearance and Behavior The ornate burrowing frog lies in Australia and is a member of the genus Opis...
Together with their brightly colored skin, this bad taste is one of their best survival adaptations. What eats the mantella frog? Small mammals, snakes and birds are the primary predators of Mantella frogs. These predators sometimes eat the frogs despite their aposematic colors warning them of ...
for moving prey, but others utilize echolocation primarily for orientation rather than for prey capture. Others feed on nectar and pollen, where they pollinate night-flowering plants that have structural adaptations designed to attract the bats. Yet other whispering bats have what is in essence ‘...
bluegill, they develop a shape that improves their swimming speed: shallow tails and deep tail muscles. These distinct responses to each type of predator represent adaptations to each predator's foraging strategy. Beetles are sit-and-wait predators, while fish can chase their prey for short ...
We tested for physiological and behavioural adaptations to cold climates in R. temporaria.No evidence of freeze protection was found in subalpine and alpin... G Ludwig,U Sinsch,B Pelster - 《Journal of Thermal Biology》 被引量: 2发表: 2015年 Culture techniques of Rana temporaria chensinensis...
Well-known toxin delivery systems range from macroscopic structures (like snake fangs or insect stingers) down to cellular adaptations (nematocysts in cnidarians). The molecular delivery system identified here represents an extension down the biological scale, and show that toxin delivery can be ...
Transcriptional silence is required for progression of the meiotic cycle. However, in cases of high asynapsis, spermatocytes can present errors in MSUC, inactivating genes crucial for meiosis and for the survival of spermatids, as well as initiating apoptosis54. Although a checkpoint in pachytene ...
