Abstract Coral bleaching is a stress response of corals induced by variety factors, but these events have become more frequent and intense in to recent climate‐change‐related temperature anomalies. We tested the hypothesis that coral reefs affected are currently heavily infested boring sponges, which playing significant role destruction their physical structure. Seventeen cover entire distributional range along Mexican Pacific coast were studied between 2005/2006, later 2009/2010. Most...
SUMMARY Species richness (S) and frequency of invasion (IF) by boring sponges on living colonies Pocillopora spp. from National Park Isla Isabel(México, East Pacific Ocean) are presented. Twelve species belonging to the genera Aka, Cliona, Pione, Thoosa Spheciospongia were found, 56% coral invaded sponges, with Cliona vermifera Hancock 1867 being most abundant (30%). Carbonate dissolution rate sediment production quantified for C. flavifodinaRützler 1974. Both exhibited similar rates...
Abstract The importance of a long‐term ecological perspective is well documented, yet data are not widely available. This paper represents the first quantitative description sublittoral sponge assemblages over long temporal scales (6 years) along coast East Pacific Ocean (Mazatlan Bay), with goal describing their levels intra‐ and inter‐annual variability, relationship to changing environmental conditions. It was possible detect an apparent short‐term pattern (intra‐annual), highly diverse...
Abstract Recent studies suggest a future increase in sponge bioerosion as an outcome of coral reef decline around the world. However, factors that shape boring assemblages reefs are not currently well understood.

Abstract The use of two types coral transplants on rock boulders was evaluated as a low‐cost alternative for rehabilitation live coverage in localities whose reef structure has been reduced considerably. Transplant success between recently broken fragments (BCF) and healed (HCF) compared assuming that initial fragmentation accelerates the attachment corals by regeneration stimulation. Two sets both were started during dry rainy seasons to contrast effect environmental stability transplant...
Two alpha growth form species of boring sponges, Cliona pocillopora sp. nov. and mucronata are described from coral reefs in the Mexican Pacific Ocean. is a light brown sponge containing tylostyles that measure 146×5 μm. Tylostyles generally curved have globular or mucronated head, sometimes placed at some distance proximal end. In addition, straight, short thick tylostrongyles centrotylote oxea occasionally appear. reported for first time eastern It red to red-orange with two types...
Three new species of coral reef boring sponges were found in remote reefs from Revillagigedo Island, an archipelago that is 386 km the continent. Cliona medinae sp. nov. a sponge with orange-yellow papillae characterized by short almost straight spirasters. tropicalis nov., yellow papillate spicule complement similar to included viridis complex. However, differs rest mainly its external morphology and differences size shape spicules. Thoosa purpurea purple colour, spicular formed tylostyles,...
Abstract Sponges are an important component of coral reef communities. The present study is the first devoted exclusively to sponges from Eastern Tropical Pacific (ETP). Eighty-seven species were found, with assemblages dominated by very small cryptic patches and boring such as Cliona vermifera ; most common in ETP reefs. We compared sponge patterns reefs, Caribbean reefs (CR) West (WPR), all have that few dominate assemblages. However, they massive or large sun exposed CR WPR, encrusting...
Sponge assemblages were examined simultaneously in 2 shallow habitats (consolidated rocks and boulder tops) May November 2002 Mazatlán Bay. Important differences found between the habitats, despite them being only 40–50 m apart. Total (35) exclusive (25) species richness higher on boulders than consolidated (22 12, respectively), 10 occurred both simultaneously. Non-metric multidimensional scaling (nMDS) combination with analysis cluster revealed a disjunct pattern distribution of sponges...
This paper focuses on Aka species boring coral of the East Pacific Ocean and Caribbean Sea (Mexico). The new cryptica sp. nov. is described from Mexican reefs, which constitutes first time that a genus reported Ocean. lives cryptically Pocillopora .

Marine and terrestrial ecosystems are declining globally due to environmental degradation poorly planned resource use. Traditionally, local government agencies have been responsible of the management natural reserves preserve biodiversity. Nonetheless, much these approaches failed, suggesting development more integrative strategies. In order discuss importance a holistic approach in conservation initiatives, coastal underwater landscape value biological/environmental indicators coral reef...
Abstract Reef encrusting calcifiers (non-scleractinian species) constitute assemblages that participate in the carbon cycle at coral reefs. Despite their apparent secondary role building reef framework, they contribute to consolidation binding sediments and inducing larval recruitment from other epilithic invertebrates. The contribution of on accretion was examined by assessment rate carbonate deposition four different simulated microhabitats using calcification units (CAUs) during 12 months...
Abstract Sponges are one of the principal agents bioerosion and sediment production in coral reefs. They generate small carbonate chips that can be found sediments, we investigated whether these could provide a means for assessment applicable to reef monitoring. We tested this hypothesis on samples from 12 Mexican reefs distributed along Pacific coast, where boring sponges were particularly abundant, quantified amount superficial three grain‐size fractions: fine (<44 μm), medium (44–210...

Immediately after earthquake, rapid response effort was coordinated by members Tsunami Paleoseismology Laboratory, Universidad Nacional Autónoma de México. Despite challenges posed Coronavirus disease 2019 (COVID-19) pandemic crisis, postearthquake...
Abstract Coral reefs are highly diverse and productive ecosystems, certain oceanographic processes, such as El Niño, have resulted in severe coral bleaching mortality of reef‐building corals to the global decline area covered by reefs. Here, we report response both green red filamentous coralline algae from central Mexican Pacific coast 2015–16 Niño event. Sea surface temperature (SST) was recorded between june 2012 December 2018. Additionally, SST, DHW Oceanic Index (ONI) provided NOAA for...
Abstract Boring sponges are an important component of bioeroder assemblages in tropical coral reefs. They considered as a potential threat for reef health, and the increase dead corals is expected to promote their abundance. The relationship between availability substrata development boring sponge was evaluated during El Niño 2015–16 at five reefs from Zihuatanejo, Guerrero, Mexico. Environment substrate quality were assessed. Overall, environment conditions remained normal relation previous...

Road construction produce abrupt changes in landscape topography, microclimate, vegetation cover and levels of traffic noise. Moreover, road networks negatively affect vertebrate abundance, population gene flow, animal behavior individual survival. Between July 2010 January 2011, we conducted 10 surveys animals killed on a Michoacán, Mexico. We recorded total 314 which included: 15 species reptiles, 13 mammals, 9 birds, 1 amphibian. Mammals were the most impacted accounting for 65% kills...
Abstract Eastern Pacific reefs are mostly made up of interlocking coral branches Pocillopora , which easily broken by physical forces associated with heavy swells and winds. In this study we investigated the potential these fragments to enable propagation boring sponges. For this, quantified frequency occurrence diversity sponges in corals recently trapped among live colonies, later tested hypothesis that colonize new corals. Nearly 80% colonies had their branches, 69% contained (11...
Abstract Zooxanthellae are dinoflagellate algae belonging to the family Symbiodiniaceae that provide energy and oxygenation corals, allowing them develop a high calcification rate. Additionally, some species of these algal symbionts seem be related coral resistance particular environmental conditions, such responses have potential cope with climate change phenomena. In this study, we examined role symbiont diversity in corals thermal stress along four reefs from Mexican Pacific after “El...
