Many pathways have been proposed to explain how exploitation can lead to extinction. One of these proposed but understudied multispecies pathways is opportunistic exploitation, which occurs when a highly valuable but rare species is encountered and targeted during exploitation of a less valuable, but ...

Many species today are in danger of extinction (灭绝) andthanks to zoos they have a chance of survival. Opponents of zoos say that they are cruel. First of all they argue zoos cannot recreate the environment in which animals live and because of this animals are bored and depressed. ...
It is now widely believed that at least some species of dinosaurs had a metabolic rate high enough for them to be endotherms (animals that maintain a relatively consistent body temperature by generating heat internally). Nevertheless, climatic explanations for the K-T extinction are not really ...
Molecular phylogenies contain information about the tempo and mode of species diversification through time. Because extinction leaves a characteristic sign... DL Rabosky - 《Evolution》 被引量: 864发表: 2010年 The evolutionary enigma of sex. Sexual reproduction entails a number of costs, and yet ...
This is unsurprising given the ability of signal sequences to be utilized across species and the benefit to using SHuffle is tied to cytoplasmic expression. We did not measure activity in the supernatant to see if the enzyme was secreted outside the cells. Although commonly used C41(DE3) did...
The current rate of extinction of species is over 1,000 times faster than during the pre-human era5. According to the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species (www.iucnredlist.org, date accessed: Jun 2016), over 20% of the 59,033 listed ...
Domestication involves adapting animals to the human-controlled environment. Genetic changes occurring during the domestication process may manifest themselves in phenotypes that render domesticated animals maladaptive for life in the wild. Domesticated
Work in this species has documented an energetic cost in the form of reduced energy intake as a result of male sexually coercive beha- viour (Magurran & Seghers 1994a), but nothing is known about whether females can adjust their physiology to minimize locomotory costs stemmin...
Exploitation of natural resources often causes habitat fragmentation, limiting species distribution and increas- ing the risk of extinction. The lack of spatial continuity in populations can have severe consequences, such as increased inbreeding (Ledig, 1992) and reduced effective population size (Gilpin...
