The garganey (Spatula querquedula) is a small dabbling duck.It breeds in much of Europe and across the Palearctic, but is strictly migratory, with the entire population moving to Africa, India (in particular Santragachi), Bangladesh (in the natural reservoirs of Sylhet district) and Australasia during the winter of the Northern hemisphere, [2] where large flocks can occur.
[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...
They are found in all temperate and tropical oceans, usually at depths of several hundred meters. [3] There are about 32 species in as many as 9 genera, although some authorities recognise fewer genera than Fishbase does. Members of the family are generally small, with some ranging up to 40 cm, but most no more than 15 cm.
Available Earth System Models suggest that ongoing ocean bio-geochemical changes could trigger reductions in ocean NPP between 3% and 10% of current values depending on the emissions scenario. [ 10 ] In 2020 researchers reported that measurements over the last two decades of primary production in the Arctic Ocean show an increase of nearly 60% ...
The kids all think they will hate the planetarium, but after watching the star show, they want to go back again after the field trip. Not only do they go back, but they all also start volunteering to work at the planetarium. This turns out to be because the director, Dr. Adams, is using a brainwashing device on them. While doing so, he ...
The Great Pacific Garbage Patch (also Pacific trash vortex and North Pacific Garbage Patch [9]) is a garbage patch, a gyre of marine debris particles, in the central North Pacific Ocean. It is located roughly from 135°W to 155°W and 35°N to 42°N . [ 10 ]
[2] [3] Marine microorganisms have been variously estimated to make up about 70%, [4] or about 90%, [5] [6] of the biomass in the ocean. Taken together they form the marine microbiome. Over billions of years this microbiome has evolved many life styles and adaptations and come to participate in the global cycling of almost all chemical elements ...
The Habakkuk Commentary or Pesher Habakkuk, labelled 1QpHab (Cave 1, Qumran, pesher, Habakkuk), was among the original seven Dead Sea Scrolls discovered in 1947 and published in 1951. Due to its early discovery and rapid publication, as well as its relatively pristine preservation, 1QpHab is one of the most frequently researched and analyzed ...
