Vagrancy in paradise: documentation of the chevron butterflyfish Chaetodon trifascialis in Kaneohe Bay, Oahu, Hawaiian islands
نویسنده
چکیده
The chevron butterflyfish Chaetodon trifascialis is an obligate corallivore found on Indo-Pacific coral reefs. The typical northern extent of the distributional range of the chevron butterflyfish overlaps with the occurrence of one of its preferred corals Acropora cytherea on reefs of French Frigate Shoals in the Northwestern Hawaiian Islands. Here I document the occurrence of a single C. trifascialis in Kaneohe Bay, Oahu outside its typical range and discuss the role of biogeographic vagrants as potential colonizers that provide direct evidence of inter-island larval connectivity in the Central Pacific Ocean.

Anomalous Growth and Reproductive Patterns in Populations of Chaetodon miliaris ( Pisces , Chaetodontidae ) from Kaneohe Bay , Oahu , Hawaiian Islands
Specimens of Chaetodon miliaris collected in Kaneohe Bay, Oahu, during a 15-month study appeared to be reproductively inactive and were smaller than were those from other Hawaiian study areas. Additionally, they lacked calanoid copepods in their diet, the main food consumed elsewhere. It is suggested that the absence of this food in their diet resulted in a dietary deficiency leading to poor gr...

Concern over the health of coral reef communities has greatly intensified in recent years, particularly with regard to the complex dynamics of global change. The synoptic spatial and temporal monitoring capabilities of remote sensing provide a valuable avenue for evaluating the impacts of local, regional and global change on this important natural resource. Hyperspectral imagery acquired over t...
متن کاملInfluence of dietary specialization and resource availability on geographical variation in abundance of butterflyfish
Empirical evidence indicates that both niche breadth and resource availability are key drivers of a species' local abundance patterns. However, most studies have considered the influence of either niche breath or resource availability in isolation, while it is the interactive effects that are likely to influence local abundance. We examined geographic variation in the feeding ecology and distri...
متن کاملGenetic and morphological characterization of a coral Species of Concern, Montipora dilatata, in Kaneohe Bay, Oahu, Hawaii
Executive Summary Montipora dilatata (a stony coral endemic to Hawaii) is one of the rarest corals known; only a few colonies have ever been found despite extensive surveys. The taxonomic status of M. dilatata is unclear, in part because coral species boundaries in general are poorly understood. In order to examine evolutionary relationships in Montipora, a suite of molecular markers (mitochond...
متن کاملReproductive System Symbiotic Bacteria Are Conserved between Two Distinct Populations of Euprymna scolopes from Oahu, Hawaii
Female Hawaiian bobtail squid, Euprymna scolopes, harbor a symbiotic bacterial community in a reproductive organ, the accessory nidamental gland (ANG). This community is known to be stable over several generations of wild-caught bobtail squid but has, to date, been examined for only one population in Maunalua Bay, Oahu, HI. This study assessed the ANG and corresponding egg jelly coat (JC) bacte...
