Can DNA barcodes of stream macroinvertebrates improve descriptions of community structure and water quality?
TLDR
It is concluded that DNA barcodes of stream macroinvertebrates will improve descriptions of community structure and water quality for both ecological and bioassessment purposes and reveal a pollution-tolerance gap.
Integration of DNA barcoding into an ongoing inventory of complex tropical biodiversity
TLDR
Adding DNA barcoding to the inventory of the caterpillars, their food plants and parasitoids in northwestern Costa Rica has substantially improved the quality and depth of the inventory, and greatly multiplied the number of situations requiring further taxonomic work for resolution.
Nuclear genomes distinguish cryptic species suggested by their DNA barcodes and ecology
TLDR
It is shown that a widespread neotropical skipper butterfly known as Udranomia kikkawai (Weeks) comprises three different species in Costa Rica, and their complete nuclear genomes totaling 15 million aligned positions reveal significant differences consistent with their 0.00065-Mbp mitochondrial barcodes and their ecological diversification.
Minimalist revision and description of 403 new species in 11 subfamilies of Costa Rican braconid parasitoid wasps, including host records for 219 species
TLDR
Three new genera are described: Michener (Proteropinae), Bioalfa ( Rogadinae) and Hermosomastax (Rogadinaes) and a consensus sequence of the COI barcodes possessed by each species is employed to diagnose the species, and this approach is justified in the introduction.
Two new species of Erythromelana Townsend, 1919 (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica
TLDR
Two new species in the genus Erythromelana Townsend, 1919 from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica are described, reared from wild-caughtcaterpillars of Eois spp.
Nine new species of Uramya Robineau-Desvoidy (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica, with a key to their identification
TLDR
Nine new species in the genus Uramya Robineau-Desvoidy are described from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica from an ongoing inventory of wild-caught caterpillars spanning a variety of families.
A new species of Phosocephala Townsend, 1908 (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica
TLDR
A new species of Phosocephala Townsend is described and a previously unknown male is described from Area de Conservación Guanacaste, northwestern Costa Rica, using morphology, life history, molecular data, and photographic documentation.
Five new species of Vibrissina Rondani (Diptera: Tachinidae) from Area de Conservación Guanacaste in Northwestern Costa Rica
TLDR
Five new species in the genus Vibrissina Rondani are described from Area de Conservación Guanacaste (ACG) and all species were reared from wild-caught sawfly larvae.
Lytopylus Förster (Hymenoptera, Braconidae, Agathidinae) species from Costa Rica, with an emphasis on specimens reared from caterpillars in Area de Conservación Guanacaste
Abstract Twelve species of Costa Rican Lytopylus are treated; these include all species reared from Lepidoptera caterpillars in Area de Conservación Guanacaste, Costa Rica, over 32 years of
Random walk modeling of adult Leuctra ferruginea (stonefly) dispersal
TLDR
In an attempt to predict the likelihood of overland dispersal by adult EPT within Philadelphia, PA, USA, a one year field study was conducted at the Schuylkill Center for Environmental Education to obtain data on local EPT taxa and dispersal behavior.
