Propagule pressure plays an important role in species invasions (Groom, 2006). Charles Darwin was the first to study specific factors related to invasions of non-native species. In his research he identified that few members of the same genus were present in habitats containing naturalized non-indigenous species (Colautti et al., 2006).
The Ozark big-eared bat (Corynorhinus townsendii ingens) is an endangered species found only in a small number of caves in Arkansas, Oklahoma and Missouri, the southern central United States.
A 2016 study by Kumar et al. [13] chemically analyzed these secretions, concluding that they may be required in chemosensory mediated communication [14] and mate choice. Similarly, in the less aggressive herb-field mouse, males are observed to groom females for longer durations and even allow females to not reciprocate. [ 15 ]

Commission Directive 2006-28-EC of 6 March 2006 amending, for the purposes of their adaptation to technical progress, Council Directive 72-245-EEC of 20 June 1972 relating to the radio interference (electromagnetic compatibility) of vehicles and Council Directive 70-156-EEC on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers ...
Ex situ research (or off-site research) is also popular among researchers looking to answer questions that are difficult to test in the field. For example, efforts to sequence the genome of the gray mouse lemur will help researchers understand which genetic traits set primates apart from other mammals and will ultimately help understand what ...
The CDC excluded male victims from the fact sheet summary, noting only that "1.3 million women were raped during the year preceding the survey" without mentioning the similar finding for men. [44] [45]
