AIM: Most studies of avian insular adaptations have focused on oceanic islands, which may not allow characters that are insular adaptations to be teased apart from those that benefit dispersal and colonization. Using birds on continental is...
Low persistence of a monocarpic invasive plant in historical sites biases our perception of its actual distribution [0.03%]
一年生入侵植物在历史遗迹中的低持续性偏误了我们对其实际分布的认识
Jan Pergl,Petr Pyšek,Irena Perglová et al.
Jan Pergl et al.
AIM: As accurate and up-to-date distribution data for plant species are rarely available, cumulative records over long periods of time are frequently used for mapping distributions, without taking into account that species do not persist in...
Phylogeographic patterns of genetic diversity in eastern Mediterranean water frogs have been determined by geological processes and climate change in the Late Cenozoic [0.03%]
晚中新世地质过程和气候变化决定了东地中海水蛙的遗传多样性谱系地理模式
Ciğdem Akın,C Can Bilgin,Peter Beerli et al.
Ciğdem Akın et al.
AIM: Our aims were to assess the phylogeographic patterns of genetic diversity in eastern Mediterranean water frogs and to estimate divergence times using different geological scenarios. We related divergence times to past geological events...

Humans and their ancestors are unique in being a fire-making species, but 'natural' (i.e. independent of humans) fires have an ancient, geological history on Earth. Natural fires have influenced biological evolution and global biogeochemica...

AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area fl...
Phylogeography of the dark kangaroo mouse, Microdipodops megacephalus: cryptic lineages and dispersal routes in North America's Great Basin [0.03%]

AIM: The rodent genus Microdipodops (kangaroo mice) includes two sand-obligate endemics of the Great Basin Desert: M. megacephalus and M. pallidus. The dark kangaroo mouse, M. megacephalus, is distributed throughout the Great Basin and our ...
Geographical and climatic limits of needle types of one- and two-needled pinyon pines [0.03%]
单针和二针松树雪帕ино的地理和气候限制

AIM: The geographical extent and climatic tolerances of one- and two-needled pinyon pines (Pinus subsect. Cembroides) are the focus of questions in taxonomy, palaeoclimatology and modelling of future distributions. The identification of the...
Phylogeography of the pallid kangaroo mouse, Microdipodops pallidus: a sand-obligate endemic of the Great Basin, western North America [0.03%]
大盆地草原鼠的谱系地理学：北美西部沙地特有物种
John C Hafner,Nathan S Upham,Emily Reddington et al.
John C Hafner et al.
AIM: Kangaroo mice, genus Microdipodops Merriam, are endemic to the Great Basin and include two species: M. pallidus Merriam and M. megacephalus Merriam. The pallid kangaroo mouse, M. pallidus, is a sand-obligate desert rodent. Our principa...
