Floristic Diversity and Dynamics of Isla Rasa, Gulf of California – a Globally Important Seabird Island
Isla Rasa, a small (0.68 km) but globally important seabird island in the Gulf of California, has a fl ora of only 14 vascular plant species found in three vegetation zones. Signifi cant physical alteration of the island’s surface and the introduction of non-native rodents, eradicated in 1995, add restoration ecology to the remarkable biology of the island. Over a century of botanical collectio...
متن کاملDeep-water polychaetes (Annelida) from the southeastern Gulf of California, Mexico.
Polychaetes inhabiting deep-sea soft bottoms from the southeastern Gulf of California were collected during four oceanographic cruises during 2000 and 2001. Sampling of benthic organisms was performed with a benthic sledge to collect epifauna and a Karling dredge for epifauna and infauna, in a depth range from 732 to 2 250 m. A list of the polychaetes that were collected and their distribution ...
متن کاملFree-living marine polychaetes (Annelida) inhabiting hard-bottom substrates in Trinidad and Tobago, West Indies.
As part of a larger comparative study, marine polychaete hard-bottom assemblages were surveyed using artificial substrate units (ASUs) deployed at four sites off the islands of Trinidad and Tobago. The polychaete fauna was represented by 19 families comprising 89 species. The syllid Exogone dispar was the most abundant polychaete followed closely by the serpulid Pseudovermilia occidentalis. At ...
متن کاملSubtype variation among bacterial endosymbionts of tubeworms (Annelida: Siboglinidae) from the Gulf of California.
Symbiosis involving chemoautotrophic bacteria allows vestimentiferan tubeworms to thrive in sulfidic marine environments. This study examined genetic variation among endosymbionts associated with three vestimentiferan species from the Gulf of California. Small subunit (16S) rRNA sequences identified two evolutionary lineages of -Proteobacteria in these worms. Phylotype-II bacteria associated wi...
متن کاملA morphometric analysis of Eunice Cuvier (Annelida, Polychaeta) species
Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E. fucata, E. insularis, E. cf. ornata, E. rubra, and Eunice sp. was ...
