is research work is a pioneer study related to the Harpacticoida Copepod species of the phytal environment of Antarctica, contributing to the knowledge of the biodiversity of copepods, associated to the macroalgae of Admiralty Bay, especially those of the Harpacticoida Order. Samples of the four genus types of Harpacticoida Copepod were found in a macroalgae (Himantothallus grandifolius) especially in its appressoria, collected in the melt water area of Admiralty Bay, King George Island… Expand

A new pelagic Alteutha (Copepoda: Harpacticoida) from Potter Cove, King George Island, Antarctica—description, ecology and information on its year round distribution
A new harpacticoid copepod species was found during a year round plankton survey in a shallow Antarctic bay and morphological characters such as shape and setation of the maxilliped and the almost complete fusion of the baseoendopod and the exopod of the fifth leg in the female are described for the first time for this genus. Expand
A new Stygonitocrella Petkovski (Copepoda: Harpacticoida) from a cave in Northern Mexico with comments on the taxonomy of the genus
It is suggested that the influence of marine transgressions in Northern Mexico was related to the origin of the new species as part of a group of troglobitic forms originated from marine interstitial ancestors that colonized the freshwater caves. Expand
Growth and Production of the Seaweed, Himantothallus grandifolius, at King George Island
Converting length to biomass showed that the plants increased their biomass by approximately 22% during this period, but this increase was almost negated by loss of frond material, due to constant erosion at the frond tips which are colonized by bacteria which promote erosion. Expand
The influence of canopy algae on vertical patterns of distribution of low-shore assemblages on rocky coasts in the northwest Mediterranean
It is shown that Cystoseira can be considered a habitat-forming species, responsible for the maintenance of two distinct low-shore assemblages, and its importance should be taken into account by policies aiming to preserve biodiversity on rocky shores. Expand
The Effects of Canopy Shadings on Algal Recruitment and Growth in a Giant Kelp Forest
The results indicate that the relatively low levels of both physical and biological disturbance in Stillwater Cove allow the establishment of a few perennial algal species that inhibit their own recruitment, as well as invasion of other species, by shading, compared with nearby kelp forests subjected to greater and more frequent disturbance. Expand
Kelp forest ecosystems: biodiversity, stability, resilience and future
The conditions in which kelp forests develop globally and where, why and at what rate they become deforested are reviewed and overfishing appears to be the greatest manageable threat to kelp forest ecosystems over the 2025 time horizon. Expand
The kelp fauna of northeast Britain. II. Multivariate classification: Turbidity as an ecological factor
Detailed faunal data relating to a sublittoral survey of kelp holdfasts in northeast Britain are presented and a primary correlation between the local composition of the holdfast fauna and turbidity is indicated. Expand
Marine diversity: the paradigms in patterns of species richness examined*
Assessment is urgently needed of the spatial scales and dynamics of species richness from point samples to assemblages, habitats and landscapes, especially in coastal areas and in the tropics, where the threats to biodiversity are greatest. Expand
The kelp fauna of northeast Britain. I. Introduction and the physical environment
A study of the sublittoral kelp fauna in northeast Britain is described and the degree of holdfast branching is shown to be independent of age and to influence significantly (along with water movement external to the holdfast) the degreeof holdfast silting. Expand
Animal species diversity driven by habitat heterogeneity/diversity: the importance of keystone structures
It is shown that ecological effects of habitat heterogeneity may vary considerably between species groups depending on whether structural attributes are perceived as heterogeneity or fragmentation, and possible effects may also vary relative to the structural variable measured. Expand
