The Phylogeny Of Paralabrax (Perciformes: Serranidae) And Allied Taxa Inferred From Partial 16s And 12s Mitochondrial Ribosomal Dna Sequences, Daniel Pondella, Matthew Craig, Jens Frank Sep 2003

The Phylogeny Of Paralabrax (Perciformes: Serranidae) And Allied Taxa Inferred From Partial 16s And 12s Mitochondrial Ribosomal Dna Sequences, Daniel Pondella, Matthew Craig, Jens Frank

Daniel Pondella

Partial sequences of 16S and 12S mitochondrial ribosomal DNA were used to examine the phylogenetic relationships of the primarily eastern Pacific genus Paralabrax (Perciformes: Serranidae) and allied taxa. Paralabrax is considered a basal serranine, which is itself considered the basal subfamily in the Serranidae. Multiple serranines reported closely related to Paralabrax from the genera Serranus, Hypoplectrus, Cratinus, and Centropristis were used as outgroups. Species from the remaining two subfamilies, Epinephilinae and Anthiinae, of the Serranidae were also used in the analyses. The tree of the Serranidae was rooted with the families Polyprionidae and Priacanthidae. Paralabrax, the Serranidae, and the Serraninae …

Lack Of Widespread Organochlorine Pesticide Contamination In South American Resident Passerines, Given Harper, A. P. Capparella, J. A. Klemens, J. A. Frick Mar 2003

Lack Of Widespread Organochlorine Pesticide Contamination In South American Resident Passerines, Given Harper, A. P. Capparella, J. A. Klemens, J. A. Frick

Given Harper

Recent studies have documented the existence of organochlorine (OC) pesticides and metabolites— notably p,p'-DDE, dieldrin and heptachlor epoxide—in the nglg range in many species of Neotropical migrant passerines that breed in the Nearctic region and winter in the Neotropics (e.g., Kannan 1991; Harper et al. 1996; Klemens et al. 2000; Bartuszevige et al. 2002). This is despite the banning and/or restricted use of OC pesticides in the United States and Canada in the 1970s and the observed decline in DDT residues in migratory songbirds seen in the 1970s (Johnston 1974). Apparently, these relatively short-lived birds are still being exposed to …
