For example, increased abundance of herbivores such as deer decrease plant diversity and species richness, [36] while other large mammalian herbivores like bison control dominant species which allows other species to flourish. [37] Plant-herbivore interactions can also operate so that plant communities mediate herbivore communities. [38]
Asparagus fern—This may apply to one of several species of the monocot genus Asparagus, which are flowering plants. Sweetfern—A flowering shrub of the genus Comptonia. Air fern—A group of animals called hydrozoans that are distantly related to jellyfish and corals. They are harvested, dried, dyed green, and then sold as a plant that can ...
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds. Adult females of many species have mouthparts adapted to pierce the skin of a host and feed on blood of a wide range of vertebrate hosts, and some invertebrates, primarily other arthropods. Some species only produce eggs ...
Catfish (or catfishes; order Siluriformes / s ɪ ˈ lj ʊər ɪ f ɔːr m iː z / or Nematognathi) are a diverse group of ray-finned fish.Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to ...
Species go extinct constantly as environments change, as organisms compete for environmental niches, and as genetic mutation leads to the rise of new species from older ones. At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction , [ 9 ] often comprising an accumulation of smaller extinction events over ...
An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3] Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
The proposed origin of tetrapods among elpistostegalian fish was called into question by a discovery made in the Holy Cross Mountains of Poland. In January 2010, a group of paleontologists (including Ahlberg) published on a series of trackways from the Eifelian stage of the Middle Devonian, about 12 million years older than Tiktaalik .
