Abstract Aim We evaluated whether patterns of species diversity (α, β and γ) rocky shore assemblages followed latitudinal gradients (i.e. LDGs) along the South American coasts, tested hypotheses related to potential processes sustaining or disrupting expected LDG pattern at various spatial scales. Location Coasts America. Taxon Macroalgae sessile/slow‐moving macrofauna on intertidal shores. Methods changes in composition across 143 sites. The degree replacement loss different scales regions...
The infraclass Euthyneura (Mollusca, Heterobranchia) exhibits significant diversity in morphology, size, life habits, and color. Several species are important for research evolution, ecology, chemistry, pharmacology. Despite Colombia’s expansive Pacific Caribbean coasts, which host ecosystems such as rocky shores coral reefs, key habitats sea slugs hares, the biodiversity of remains largely understudied. This study aims to expand inventory intertidal shallow subtidal reef environments...
Transplantation of coral fragments is a common procedure for the restoration degraded reefs. In Tropical Eastern Pacific (TEP), branching Pocillopora damicornis main reef-builder, and it frequently propagates through natural fragmentation; therefore candidate efforts in this region. To evaluate usefulness P. reef TEP, three lengths were used: small (1–2 cm), medium (4 cm) large (7 cm). Fragments these sizes attached on back-reef, flat crest La Azufrada (Gorgona Island, Colombian Pacific)....
Acquiring marine biodiversity data is difficult, costly, and time-consuming, making it challenging to understand the distribution abundance of life in ocean. Historically, approaches sampling over large geographic scales have advocated for equivalent effort across multiple sites minimize comparative bias. When cannot be equalized, techniques such as rarefaction been applied biases by reverting diversity estimates numbers samples or individuals. This often results oversampling wasted...
Regular sea-urchins are one of the main bioeroding organisms affecting coral reefs around world. The abundance, distribution and bioerosion rate sea-urchin Centrostephanus coronatus, were determined in different reef zones Playa Blanca fringing (Gorgona Island, Colombian pacific coast) during 1997 1998. erosion rates calcinating gut content to eliminate all organic components preserve inorganic portion calcium carbonate. C. coronatus showed highest densities towards central (plain-crest...
Organisms found on rocky shores must endure harsh environmental conditions during tidal changes but scientific studies tropical are scarce, particularly in Colombian shores. Here we describe the spatial distribution of macroinvertebrates associated to intertidal ecosystems Gorgona Island, Colombia (Tropical Eastern Pacific). Sampling was carried out four localities around Island: La Ventana and Camaronera (sampled October 2010) Mancora El Muelle March 2011). Two methodologies were used:...

The composition of marine macroinvertebrates in two localities (Isla Palma and Los Negritos) Malaga Bay was studied. This bay is located the Pacific coast Colombia recently declared National Natural Park. rapid ecological assessment revealed a total 128 species belonging to 64 families 11 classes (including threatened species). most common groups were: Gastropoda (27%), Polychaeta (26%), Malacostraca (16%) Pelecypoda (13%). Even though sites are relatively near, being apart only by 6 km,...
The environmental protection of tropical marine and coastal areas faces different challenges due to the diversity aspects related these areas, which include natural, social economical issues. Despite challenges, efforts for are urgent nowadays because dramatical increase human threats like habitat destruction population growth. Malaga Bay (MB) is a tectonic estuarine system located in Panama Bight (central region Colombian Pacific coast), its origin shows important characteristics few sites...
The increasing activity in morphological studies has provided new tools to analyses the shape quantitatively, these quantitative measurements allow researcher examine variation and perform analysis differences among species shapes, where geometric morphometrics rendered great results last years. This study was focused on assessing morphometric between populations of Lottia mesoleuca family Lottidae, an abundant group gastropods rocky ecosystems Bahía Málaga Isla Gorgona (Colombian Pacific)....
The form, condition, and survival of coral reefs depends on the balance between construction destruction. Natural processes such as bioerosion can cause this to lean towards destruction, threatening these ecosystems. Polychaetes sipunculids are members boring community; however, knowledge their identity role in bioerosive process capacity remove calcium carbonate (CaCO 3 ) Eastern Tropical Pacific (ETP) is scarce. To tackle problem, 5 experimental units Pocillopora spp. branches were...
Abstract Constancy or scale variance of species–area and abundance–area relationships has rarely been considered within relatively small spatial domains a local assemblage. Patterns species/abundance–area were experimentally investigated in stone‐associated molluscan community on subtropical boulder shore. In order to systematically examine the effects variation habitat area while maintaining other characteristics constant through time, naturally occurring stones selected divided into...
The production and accumulation of carbonate reef framework is the positive component development. main organisms participating in this process are corals crustose coralline algae (CCA) because their combined calcareous skeletons construct help to consolidate frameworks. We assessed contribution (i.e. gross production) CCA calcium (CaCO 3 ) budget 2 largest most developed reefs Gorgona Island (Pacific coast Colombia). On each zone (back [BR], flat [RP], front [RF], slope [RS]) these reefs,...

Standardized methods for effectively and rapidly monitoring changes in the biodiversity of marine ecosystems are critical to assess status trends ways that comparable between locations over time. In intertidal subtidal habitats, estimates fractional cover abundance organisms typically obtained with traditional quadrat-based methods, collection photoquadrat imagery is a standard practice. However, visual analysis quadrats, either field or from photographs, can be very time-consuming....
