The Lafken Mapu Lahual Coastal Marine Protected Area of Multiple Uses (Lafken Mapu Lahual), Osorno coast, southern Chile, is one of the first protected areas created in Chile during 2006, but only in 2019 its Management Plan was presented. This study provides information on its marine mammal species to be used in future biodiversity monitoring plans. The sighted mammals were recorded and counted through 18 navigation tracks and one observation point in the 2014-2015 austral breeding season. Five species were recorded systematically (one whale species, two dolphin species, one marine otter species and a one sea lion species). Two of them (Lontra felina and Balaenoptera musculus) are classified by the IUCN in the conservation category corresponding to Endangered. Laken Mapu Lahual is an important area for the species of whales that use it for their migratory route to the south of Chile.

A comprehensive research study of Cabeza de Toro and Punta Cana’s fishing and tourism industries reveal viability of economic solutions between the hospitality industry, fishermen, and the government to reduce practices harmful to the coastal marine ecosystem.  Recent research studies of Punta Cana and Cabeza de Toro’s coastal marine ecosystem demonstrate diminishing coral coverage and reduced fish populations.  Causes for the decline of the coastal marine ecosystem include overfishing, illegal fishing of species conducive to coral health, and the destruction of mangrove sanctuaries.  By methods of survey and in-person interview, researchers gathered data on over 20% of Cabeza de Toro’s fisherman population with the intent of further developing a co-management plan for the recently established marine protected area.  Data collection included qualitative and quantitative research into income and livelihoods of Cabeza de Toro fishermen, fishing practices, interest in alternative work opportunities, and strength of social responsibility and environmental beliefs.  Findings demonstrate that viable economic applications exist in forging partnerships between fishermen, the tourism and hospitality industries, and the local

The Cayos Cochinos, a set of two small islands (Cayo Menor and Cayo Mayor) and thirteen coral cays located off the north coast of Honduras, are picturesque in their postcard beauty. A Google search brings up descriptions of the islands as "diamonds in the rough," "a divers' and snorkelers' paradise," "the most stunning scenery ever to behold," "a private paradise." The archipelago's beauty is undeniable, yet the costs of "protecting" its natural attractions are high, especially to the Afro-indigenous Garifuna who have relied on the area's resources since their arrival in the early 1800s. This article addresses the challenges to Garifuna culture and traditions-particularly the practice of fishing-created by the establishment of the Cayos Cochinos Marine Protected Area (CCMPA), and the promotion of ecotourism as a replacement livelihood strategy through the 2004-2009 CCMPA management plan.

AbstractRecent widespread shallow coral reef loss has led to calls for more holistic approaches to coral reef management, requiring inclusion of all ecosystems interacting with coral reefs in management plans. Yet almost all current reef management is biased towards shallow reefs, and overlooks that many reef species can also be found on mesophotic coral ecosystems (MCEs; reefs 30 −150 m). This study presents the first detailed quantitative characterisation of MCEs off Cozumel, in the Mexican Caribbean and provides insights into their general state. We investigate whether MCEs within the marine park have similar ecological communities to mesophotic reefs outside protection, despite widely recognised shallow reef impacts outside the protected area. Results show some taxon specific differences in MCE benthic communities between sites within the protected area and areas outside; although overall communities are similar. Regardless of protection and location, and in contrast to shallow reefs, all observed Cozumel MCEs were continuous reefs dominated by calcareous macroalgae, sponges, octocorals, and black corals. Hard corals were present on MCEs, but at low abundance. We found that 42.5 % of fish species recorded on Cozumel could be found on both shallow reefs and MCEs, including many commercially-important fish species. This suggest that MCEs may play a role in supporting fish populations. However, regardless of protection status and depth we found that large-body fishes (>500 mm) were nearly absent at all studied sites. MCEs should be incorporated into the existing shallow-reef focused management plan in Cozumel, with well informed and implemented fisheries and harvesting regulations.

The Katalalixar National Reserve (KNR) lies in an isolated marine protected area of Magellan Sub-Antarctic channels, which represent an important area for marine biodiversity and macroalgal conservation. The present study is the first report of the species Lessonia spicata, “huiro negro”, in the Magellan Sub-Antarctic channels. This finding has implications for macroalgal biogeography and conservation concerns in the Chilean coast. In the ecological assessments of the KNR in 2018 we found populations of L. spicata, specifically on rocky shores of Torpedo Island and Castillo Channel. The morphological identification and molecular phylogeny based on nuclear (ITS1) sequences revealed that these populations of Lessonia are within the lineage of L. spicata of central Chile. This report increases the species richness of kelps for the Magellan Sub-Antarctic Channels from two to three confirmed species (L. flavicans, L. searlesiana and L. spicata), and it also extends the southern distribution range of L. spicata. This species has high harvest demand and is moving towards southern Chile; thus, these populations should be considered as essential for macroalgal conservation in high latitudes of South America.

This research is part of the LTER (Long-Term Ecological Research) project, a network of terrestrial, freshwater, transitional water and marine sites, on which ecological research is conducted on a multi-decade scale. LTER studies ecosystems, their dynamics and evolution, the relationships between biodiversity and ecological functionality, water quality, productivity, the role of resource availability, the effects of pollution and climate change. The research focuses on the study of the variability of zooplankton groups in the Portofino marine protected area, in Punta Faro. The samplings were carried out in the years 2018–2019, and the results were compared with the values of the years 2003–2005, interesting from a meteorological climatic and biological point of view. The plankton community of the Punta Faro system was analyzed by means of a modeling approach to obtain information on the functionality and health status of the system and to verify whether this has undergone any alterations in the last decade. The analyses carried out show a clear difference between the three-year period 2003–2005 and the two-year period 2018–2019, highlighting how environmental changes, such as the increase in temperature, have led to higher costs of system functioning in the last two years. The mesozooplankton community has changed both in terms of abundance of organisms and in terms of organization and functionality.
