Many bird leave for the winter, migrating south to warmer climes. Those that stay avoid the hazards of migration and maintain a year-round territory. Ever wonder how birds stay warm in the winter?
The mallard has hybridised with more than 40 species in the wild, and an additional 20 species in captivity, [13] though fertile hybrids typically have two Anas parents. [14] Mallards and their domestic conspecifics are fully interfertile; many wild mallard populations in North America contain significant amounts of domestic mallard DNA. [15] [16]
Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
Winter is upon the North Texas and Southwestern Oklahoma region and the conditions of this season present challenges to our region’s wild animals. 'Move, change or die': How these animals adapt ...
In the winter, when many of these birds are migrating, farmers are now flooding their fields in order to provide temporary wetlands for birds to rest and feed before continuing their journey. [146] Rice is a major crop produced along this flyway, and flooded rice paddies have shown to be important areas for at least 169 different bird species ...
Diapause in insects is a dynamic process consisting of several distinct phases. While diapause varies considerably from one taxon of insects to another, these phases can be characterized by particular sets of metabolic processes and responsiveness of the insect to certain environmental stimuli. [6]
Plants have evolved numerous strategies to deal with cold air, frozen soil, and in the coldest of conditions, lack of water through the winter. Brr! Here are 4 ways plants, trees survive frigid ...
