The past processes that have shaped geographic patterns of genetic diversity may be difficult to infer from current patterns. However, in species with sex differences in dispersal, differing phylogeographic patterns between mitochondrial (mt) and nuclear (nu) DNA may provide contrasting insights into past events. Forest elephants (Loxodonta cyclotis) were impacted by climate and habitat change during the Pleistocene, which likely shaped phylogeographic patterns in mitochondrial (mt) DNA that have persisted due to limited female dispersal.

A study was conducted to understand trends in the conservation of the locally adapted critically endangered radish landrace ‘Newar ’ (Raphanus jaunpurensis sp. nova.), conventionally grown in certain saline areas of Jaunpur city, Uttar Pradesh for use in salads, and for other traditional household uses, as well as the sale of fresh roots and seeds. An exploratory research design was adopted to collect data from 40 respondents, including 5 key informants.

In the midst of Earth’s sixth mass extinction event, non-native species are a driving factor in many imperiled species’ declines. One of the most widespread and destructive alien invasive species in the world, wild pigs (Sus scrofa) threaten native species through predation, habitat destruction, competition, and disease transmission. We show that wild pigs co-occur with up to 87.2% of imperiled species in the contiguous U.S. identified as susceptible to their direct impacts, and we project increases in both the number of species at risk and the geographic extent of risks by 2025.
