Demographic estimation methods for plants with dormancy
M. Kery, K.B. Gregg
2004, Animal Biodiversity and Conservation (27) 129-131
Demographic studies in plants appear simple because unlike animals, plants do not run away. Plant individuals can be marked with, e.g., plastic tags, but often the coordinates of an individual may be sufficient to identify it. Vascular plants in temperate latitudes have a pronounced seasonal life–cycle, so most plant demographers...

Designation of the type species of Musaraneus Pomel, 1848 (Mammalia: Soricomorpha: Soricidae)
N. Woodman
2004, Proceedings of the Biological Society of Washington (117) 266-270
The genus name Musaraneus often is attributed to Brisson (1762), however, most of Brisson's names are unavailable. Pomel (1848) subsequently made the name Musaraneus available, but did not designate a type species. The 18 species that Pomel listed under Musaraneus currently are distributed among five modern genera, two...

Coping with unobservable and mis-classified states in capture-recapture studies
W. L. Kendall
2004, Animal Biodiversity and Conservation (27) 97-107
Multistate mark-recapture methods provide an excellent conceptual framework for considering estimation in studies of marked animals. Traditional methods include the assumptions that (1) each state an animal occupies is observable, and (2) state is assigned correctly at each point in time. Failure of either of these assumptions can...
