Systematics of the Genus Rhagovelia Mayr (Heteroptera: Veliidae) in the Western Hemisphere (Exclusive of the angustipes Complex)
Molecular systematics and adaptive radiation of Hawaii's endemic Damselfly genus Megalagrion (Odonata: Coenagrionidae).
TLDR
Relations among 56 individuals from 20 of the 23 described species using maximum likelihood and Bayesian phylogenetic analysis of mitochondrial and nuclear DNA sequence data are examined to propose a general model for the development of endemic damselfly species on Hawaiian Islands and document five potential cases of hybridization.
Marine Resource Management in the Hawaiian Archipelago: The Traditional Hawaiian System in Relation to the Western Approach
Over a period of many centuries the Polynesians who inhabited Hawai‘i developed a carefully regulated and sustainable “ahupua‘a” management system that integrated watershed, freshwater and nearshore…
Global diversity of true bugs (Heteroptera; Insecta) in freshwater
TLDR
Aquatic Heteroptera are notable for utilizing an exceptionally broad range of habitats, from marine and intertidal to arctic and high alpine, across a global altitudinal range of 0–4,700 m.
An annotated checklist of the plant bugs of Colorado (Heteroptera: Miridae)
Islands under islands: The phylogeography and evolution of Halocaridina rubra Holthuis, 1963 (Crustacean: Decapoda: Atyidae) in the Hawaiian archipelago
TLDR
A survey of 573 individuals collected from 34 sites on the islands of Hawai’i, Maui, and Oahu revealed 13 distinct genetic groups belonging to eight divergent lineages of Halocaridina, with no individuals being exchanged between them.
Molecular phylogenetic analysis of the dragonfly genera Libellula, Ladona, and Plathemis (Odonata: Libellulidae) based on mitochondrial cytochrome oxidase I and 16S rRNA sequence data.
TLDR
The paraphyly of Libellula is rejected and the outgroup status of Orthemis ferruginea and Pachydiplax longipennis is accepted, largely consistent with morphologically based subgeneric classifications.
Hawaiian Damselflies: A Field Identification Guide
Evaluating the Effects of Introduced Rainbow Trout (Oncorhynchus Mykiss) on Native Stream Insects on Kauai Island, Hawaii; Contribution No. 2001-012 to the Hawaii Biological Survey, Bishop Museum
TLDR
The results demonstrate that the threats posed by conspicuous introduced species such as trout should not be assumed a priori on the basis of postulated negative interactions, because this may divert limited resources from programs aimed at control of other, potentially more destructive introduced taxa such as inconspicuous poeciliid fishes.
