ABSTRACT We analyse the concept of carrying capacity (CC), from populations to biosphere, and offer a definition suitable for any level. For communities ecosystems, CC evokes density‐dependence assumptions analogous those population dynamics. At biosphere level, human is uncertain dynamic, leading apprehensive rather than practical conclusions. The term widely used among ecological disciplines but remains vague elusive. propose following definition: ‘the limit growth or development each all...
The state of scientific knowledge about the vaquita, Phocoena sinus , is presented, a critically endangered endemic species Upper Gulf California, Mexico. Several bibliographic repositories were explored, selecting Web Science because it considers Citation Index as selection criterion. A bibliometric and analysis literature was carried out. network associations built based on co-occurrence sets keywords, which reflect relevance research topics discussed. Two stand out: population...
Abstract In recent years, more than 130 extinctions have been estimated to occurred in the marine realm. Here we review this body of evidence and show that figure may actually be overestimated by as much 50%. We argue previous estimates not fully taken into account critical uncertainties such naturally variable geographical distributions, misinterpreted documentary evidence. However, current indicates some sharks, rays reef‐associated species, although necessarily geographically restricted,...
ABSTRACT The world's smallest porpoise—the vaquita ( Phocoena sinus )—is on the brink of extinction. Endemic to upper Gulf California, it has dwindled fewer than 19 individuals in 2023. primary source mortality is drowning gillnets set for totoaba (a giant croaker fish). Our review past 50 years efforts simultaneously attain conservation goals and economic social fisheries concludes that they have consistently failed meet lowest expectations any stakeholders. time therefore come recognise...
The state of Campeche, Mexico, harbors one the largest green turtle (Chelonia mydas) rookeries Wider Caribbean Region. Since 1970s, harvesting this population was common practice, but it has since ceased, and is rebounding as a consequence. In rookery, during past 37 years (1984-2020), positive relationship between annual number nesting females hatchlings they produce revealed long-term signal that we postulate could be related to environmental factors. To investigate more deeply, adopt...
Abstract Ecosystems that change through time impose new scientific challenges for fisheries management advice. We present a case study to illustrate our view on how face such challenges. The Pink Shrimp fishery in the Southern Gulf of Mexico has collapsed. Annual yields were about 24,000 metric tons during mid-1950s early 1970s; currently, they are 1,200 tons. Overfishing was assumed as main cause, but single-species models failed provide advice necessary recovery. An inverse relationship...
The Galapagos Marine Reserve is one of the largest marine protected areas in world, hosting a high species diversity and endemism supporting economically important artisanal fisheries for local people tourists. To ensure proper management conservation an ecosystem necessary to determine species' contributions functions organization. We characterized structure functioning southeastern Archipelago shelf by building mass balanced Ecopath model representing period 2001–2004. considered 72...
Antecedentes y Objetivos: La restauración ecológica se ha centrado en los componentes físicos vegetales de ecosistemas, dejado lado a la fauna silvestre sus interacciones. Chelonia mydas es un macroherbívoro peligro extinción que anida playas México Cuba, e influye vegetación costera con aportaciones materia orgánica. Los objetivos este estudio fueron analizar su recuperación poblacional, índice del verdor duna, así como cantidad orgánica estimada nidadas antes después implementación una...
All species of sawfish are listed by the International Union for Conservation Nature (IUCN) as endangered or critically endangered. In fact, smalltooth Pristis pectinata, and largetooth pristis, have been declared to be regionally locally extinct from US Atlantic coast Gulf California, Mexico, respectively, likely due overfishing. However, here we dispute these claims illustrating how lack existence a given within region can misconstrued evidence extinction.
Marine finfish landings in Cuba have decreased during the last 30 years. However, Cuba's most productive fishing region, certain species, including rays, herrings, and snappers, increased over past decade. Despite these anomalies, no comprehensive analysis of interactions between multispecies landing dynamics, environmental factors, effort has been carried out. This study estimates dynamics 1981 2017 on southeastern coast Cuba. Dynamic factor analyses (DFA) were performed to...
Abstract The relationship between body size and risk of extinction has been the focus much recent attention; however, it only stated for a few groups inhabiting restricted areas. Based on IUCN list other public records, we suggest that vulnerability is trend among all vertebrates, especially tetrapods. In case fish, our results show may be subordinate to another factor named concealment. Other plausible explanations about this difference could human preference large terrestrial vertebrates...
We evaluated the fish community structure in three mangrove systems from la Paz bay, southwestern gulf of California, mexico, during two annual cycles separated by 30 yrs (1980-1981 and 2009-2010). The system have suffered different degrees anthropogenic impact that range relatively pristine (Balandra) to minor impacts development (Zacatecas), highly modified (Enfermeria). A robust comparison between periods was attained field sampling identification fishes using a museum collection. Species...
In the present study we developed a trophic model (ECOPATH with ECOSIM), to describe structure and functioning of Bahía Magdalena estuarine ecosystem. The model, constituted by 24 functional groups, indicates that one third total ecosystem biomass is produced secondary tertiary levels. magnitude flows in system transfer efficiency among levels, are similar those observed other tropical systems around world. A large proportion directed maintenance web structure. value connectance index (CI)...
