Advancing marine conservation
Three new species of pygmy seahorse are described from Indonesia: Hippocampus pontohi and H. severnsi from Bunaken Island, off Sulawesi, and H. satomiae from Derawan Island, off Kalimantan. They are considered to be closely related to each other and to Hippocampus colemani. All three species are morphologically distinguished from the larger species of seahorses by …

Community and resource user support has often been declared as essential to achieving globally agreed targets for marine protection. Given that Indigenous Peoples in Canada have resource use rights, we engaged two Indigenous communities in British Columbia for their views on marine planning and protected areas. We developed a three-phased approach for executing our research: …
The four axes of excellence in scholarship are discovery,integration, application, and teaching (Boyer 1990).Yet the predominant currency of recognition, prestige,and mobility in science is publication in top-tier acade-mic journals (Bedeian 1996). For both faculty and stu-dents, this creates a significant barrier to engagement incommunity-based scholarship. As competition for lim-ited science positions increases pressure to publish, …
The intensity of marine activities in the exclusive economic zone (EEZ) of British Columbia, Canada, was quantified. Humans use the ocean for a multitude of purposes, many of which have a direct impact on marine life and habitat. Yet such uses are seldom assessed in an integrated fashion. Using a GIS approach, spatial information for …
The long-snouted seahorse (Hippocampus guttulatus) (Cuvier, 1829), was used to validate the predictive accuracy of three progressively realistic models for estimating the realized annual fecundity of asynchronous, indeterminate, multiple spawners. Underwater surveys and catch data were used to estimate the duration of the reproductive season, female spawning frequency, male brooding frequency, and batch fecundity. The …
A 2-year experimental seining programme and underwater visual censuses were undertaken to quantify the direct effects of active demersal fishing on the population structure and relative abundance of two sympatric seahorse species of conservation concern: the European long-snouted seahorse, Hippocampus guttulatus Cuvier 1829 and the short-snouted seahorse, Hippocampus hippocampus L. The influence of habitat preference on population-level …
During the past six years, 15 new seahorse species (Syngnathidae: Hippocampus) have been described on the basis of morphological characters. This approach is known to be problematic, and most species names in Hippocampus are now considered to be synonyms. Genetic methods have great potential to resolve the confused taxonomy of the genus, but none have …
Benthic status of 28 near-shore, artisanal, coral reef fishing grounds in the central Philippines was assessed (2000–2002) together with surveys of the seahorse, Hippocampus comes. Our measures of benthic quality and seahorse densities reveal some of the most degraded coral reefs in the world. Abiotic structure dominated the fishing grounds: 69% of the benthos comprised …
This study examined how habitat associations changed with ontogeny in the Tiger tail seahorse Hippocampus comes Cantor, 1850, over four reef zones in a coral reef ecosystem. Hippocampus comes showed ontogenetic differences in their use of habitat at the scale of reef zones (macrohabitat) and holdfasts (microhabitat). Across reef zones, juvenile size classes (25–105 mm …
