Photo-identification of juvenile hawksbills using facial scales
(2010)The ability to identify individuals within a population is a key issue for most behavioral, ecological and conservation studies. Most sea turtle mark-recapture studies use external flipper tags (metal or plastic) previously ... -
Phylogenetic analyses of novel squamate adenovirus sequences in wild-caught Anolis lizards
(2013)Adenovirus infection has emerged as a serious threat to the health of captive snakes and lizards (i.e., squamates), but we know relatively little about this virus' range of possible hosts, pathogenicity, modes of transmission, ... -
Phylogenetic analysis of ecological and morphological diversification in Hispaniolan trunk‐ground anoles (Anolis cybotes group)
(2003)Anolis lizards in the Greater Antilles partition the structural microhabitats available at a given site into four to six distinct categories. Most microhabitat specialists, or ecomorphs, have evolved only once on each ... -
Phylogenetic relationships of the order insectivora based on complete 12S rRNA sequences from mitochondria
(1999)Despite numerous studies, there is no single accepted hypothesis of eutherian ordinal relationships. Among the least understood mammalian orders is the group Insectivora. Currently, molecular and morphological data are in ... -
Phylogenetics of Leptocereus (Cactaceae) on Hispaniola: clarifying species limits in the L. weingartianus complex and a new species from the Sierra de Bahoruco
(2021)The Antillean genus Leptocereus represents an in-situ radiation among the Greater and Lesser Antilles of 19 currently recognized species. Extensive fieldwork carried out in the Dominican Republic over recent years has ... -
Phylogeographic structure within the fiddler crabs Leptuca thayeri and Uca maracoani (Brachyura, Ocypodidae) along the tropical West Atlantic
