Each spiderling was presented simultaneously with one individual of each prey species in a randomized design.
The relative poor performance of the DFA may be attributed to the use of fewer individual of each species.
Nested census designs guarantee only that one individual each of a given number of species is within the sampled area, but we are almost always concerned with the loss or protection of more than one individual of each species.
Of 19 intestines of domestic cats (Felis s. catus) and five of European wildcats (Felis s. silvestris) analyzed by segmental sedimentation and counting technique (SSCT), infection by E. multilocularis was observed for one individual of each species, resulting in a prevalence estimated at 5%, (CI95%: 1 26) in domestic cats and at 20% (CI95%: 1 72) in wildcats.
These models, which assume identical life history and movement properties for each individual of each species, produce collective properties of communities, such as abundance distributions, range distributions, spatial variation in abundance, species area curves, and spatial variation in species composition, that match many empirical patterns.
But this time, they analyzed large amounts of nuclear DNA sequences from one individual of each of the three existing elephant groups (Asian elephants, African forest elephants, and Africa savanna elephants), and from two elephant species that recently became extinct (a mammoth and a mastodon).
With regards to number three, it also seems exceedingly unlikely that each and every individual of each and every ET society forever lacks interest in communication and/or exploration.
A single individual of each of three additional species (Picoides pubescens, Passer domesticus, and Columba livia) was found in a moribund state.
A root damage treatment simulating gopher herbivory was applied to one individual of each pair with a 7.5 cm diameter bore Dutch Mud Soil Auger.
Briefly, the next generation matrix contains the numbers of individuals that are infected by one infected individual of each type-at-birth during the time it is infectious.
