Sylvilagus Parentum
The Suriname tapeti (''Sylvilagus parentum'') or Suriname lowland forest cottontail is a South American species of cottontail rabbit described in 2017. It is known from the lowlands of western Suriname, and was described from specimens collected by Dutch scientists in the 1980s. Its size is relatively large for a South American cottontail rabbit. The rabbit is likely already threatened due to environmental degradation in the region, and its discovery could boost conservation efforts in the area. It was discovered by Portland State University Portland State University (PSU) is a public research university in Portland, Oregon. It was founded in 1946 as a post-secondary educational institution for World War II veterans. It evolved into a four-year college over the following two decades ... Professor Luis Ruedas.

Cottontail Rabbit
Cottontail rabbits are the leporid species in the genus ''Sylvilagus'', found in the Americas. Most ''Sylvilagus'' species have stub tails with white undersides that show when they retreat, giving them their characteristic name. However, this feature is not present in all cottontails nor is it unique to the genus. The genus is widely distributed across North America, Central America and northern and central South America, though most species are confined to some particular regions. Most species live in nests called forms, and all have altricial young. An adult female averages three litters per year, which can occur in any season; occurrence, and litter size depend on several factors including time of the year, weather, and location. The average litter size is four but can range from as few as two to as many as eight, most of whom do not go on to survive to adulthood. Cottontail rabbits show a greater resistance to myxomatosis than European rabbits. Evolution Cottontails ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environmental Degradation
Environmental degradation is the deterioration of the environment (biophysical), environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. Environmental concerns can be defined as the negative effects of any human activity on the environment. The biological as well as the physical features of the environment are included. Some of the primary environmental challenges that are causing great worry are air pollution, water pollution, natural environment pollution, rubbish pollution, and so o Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change, high-level PaneI on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 2017
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with ...
