Resumen en inglés

The Endangered Antillean manatee Trichechus manatus manatus is one of the most threatened aquatic mammal species in Mexico and the wider Caribbean region. The decline of this subspecies is mainly a result of historical exploitation and the impact of current coastal development. The conservation strategies adopted for the Antillean manatee include habitat protection, reduction of the most severe threats, and the rescue of stranded, orphaned or injured individuals and their management in captivity. This latter strategy has produced positive outcomes in some countries but has been the subject of controversy in others, including Mexico. We analyse the benefits and challenges associated with the management of captive manatees in Mexico, and the consequences of a lack of government policy and strategy for the post-rehabilitation release of individuals. We describe the evolution of this controversy from 1997-2017 in Mexico, analyse the consequences and implications for the conservation of the species, and propose an integrated management strategy that could address the issues raised. Although this strategy has been developed in the context of Mexico, it is applicable to management of this species across the Caribbean region.

Resumen en inglés

Although many large mammals currently face significant threats that could lead to their extinction, resources for conservation are often scarce, resulting in the need to develop efficient plans to prioritize conservation actions. We combined several methods in spatial ecology to identify the distribution of the endangered Baird's tapir across its range from southern Mexico to northern Colombia. Twenty-eight habitat patches covering 23% of the study area were identified, harboring potentially 62% or more of the total population for this flagship species. Roughly half of the total area is under some form of protection, while most of the remaining habitat (~70%) occurs in indigenous/local communities. The network with maximum connectivity created from these patches contains at least one complete break (in Mexico between Selva El Ocote and Selva Lacandona) even when considering the most generous dispersal scenario. The connectivity analysis also highlighted a probable break at the Panama Canal and high habitat fragmentation in Honduras. In light of these findings, we recommend the following actions to facilitate the conservation of Baird's tapir: 1) protect existing habitat by strengthening enforcement in areas already under protection, 2) work with indigenous territories to preserve and enforce their land rights, and help local communities maintain traditional practices; 3) re-establish connections between habitat patches that will allow for connectivity across the species' distribution; 4) conduct additional noninvasive surveys in patches with little or no species data; and 5) collect more telemetry and genetic data on the species to estimate home range size, dispersal capabilities, and meta-population structure.

Resumen en español

Entre las estrategias para mitigar la pérdida de especies, específicamente del jaguar (Panthera onca), se encuentran las Áreas Regionales para la Conservación del Jaguar. La mayoría de los trabajos para la conservación de la especie se realizan desde la perspectiva ecológica, siendo escasos aquellos referidos a la sociedad y su relación con el ambiente. El objetivo de este trabajo es analizar la perspectiva que sobre el jaguar tienen los habitantes de dos comunidades insertas en áreas para su conservación en Nayarit, México. Se realizaron 58 entrevistas semiestructuradas a actores clave. Los resultados indican que los principales problemas respecto a la convivencia con el jaguar son la desinformación que se tiene sobre la especie, la escala de valores de las comunidades y la prevalencia de la cultura del consumo, lo que representa uno de los principales obstáculos para su conservación. Se identificó una inclinación estética positiva hacia el jaguar, siendo este resultado un posible punto de partida para la implementación de estrategias de educación ambiental. Con los resultados obtenidos se busca contribuir al entendimiento de las posturas de las comunidades con la finalidad de incrementar las probabilidades de éxito de estrategias de conservación.

Resumen en inglés

Strategies to mitigate the loss of species, specifically the jaguar (Panthera onca), include Regional Areas for Jaguar Conservation. Most of the work to conserve this species is undertaken from an ecological perspective, and few are related to society and its relation with the environment. The purpose of this article was to analyze the perspectives of the inhabitants of two communities regarding jaguars in areas for its conservation in Nayarit, Mexico. Fifty-eight semi-structured interviews were conducted with key actors. The results indicate that the main problems regarding coexistence with jaguars are lack of information about the species, the scale of values of communities, and the prevalence of a consumer culture, which constitutes one of the main obstacles to its conservation. A positive aesthetic inclination towards the jaguar was identified, which could serve as a possible starting point for the implementation of environmental education strategies. The results contribute to the understanding of the point of view of the communities in order to increase the chances of success of conservation strategies.

Resumen en inglés

Species distribution models (SDMs) are statistical tools used to develop continuous predictions of species occurrence. ‘Integrated SDMs’ (ISDMs) are an elaboration of this approach with potential advantages that allow for the dual use of opportunistically collected presence-only data and site-occupancy data from planned surveys. These models also account for survey bias and imperfect detection through the use of a hierarchical modelling framework that separately estimates the species–environment response and detection process. This is particularly helpful for conservation applications and predictions for rare species, where data are often limited and prediction errors may have significant management consequences. Despite this potential importance, ISDMs remain largely untested under a variety of scenarios. We performed an exploration of key modelling decisions and assumptions on an ISDM using the endangered Baird’s tapir (Tapirus bairdii) as a test species. We found that site area had the strongest effect on the magnitude of population estimates and underlying intensity surface and was driven by estimates of model intercepts. Selecting a site area that accounted for the individual movements of the species within an average home range led to population estimates that coincided with expert estimates. ISDMs that do not account for the individual movements of species will likely lead to less accurate estimates of species intensity (number of individuals per unit area) and thus overall population estimates.

This bias could be severe and highly detrimental to conservation actions if uninformed ISDMs are used to estimate global populations of threatened and data-deficient species, particularly those that lack natural history and movement information. However, the ISDM was consistently the most accurate model compared to other approaches, which demonstrates the importance of this new modelling framework and the ability to combine opportunistic data with systematic survey data. Thus, we recommend researchers use ISDMs with conservative movement information when estimating population sizes of rare and data-deficient species. ISDMs could be improved by using a similar parameterization to spatial capture–recapture models that explicitly incorporate animal movement as a model parameter, which would further remove the need for spatial subsampling prior to implementation.

Resumen en español

Se realizó un muestreo intensivo y sistematizado de la araneo fauna del bosque mesófilo de montaña (BMM) en la Reserva de la Biosfera El Triunfo, Chiapas, México, para analizar su composición, riqueza de especies, abundancia y proporción de especies no descritas, y para comparar estos resultados con los encontrados en otros BMMs. Se muestrearon diez parcelas en dos temporadas (secas y lluvias) empleando diferentes técnicas de muestreo sobre dos estratos (suelo y sotobosque). Se colectó un total de 7,432 especímenes, correspondientes a 28 familias, 78 géneros y 111 morfoespecies. Se encontró una alta proporción de especies no descritas (58.6%). Para 11 especies descritas originalmente con un solo sexo, se encontró el otro sexo. Cinco especies y un género fueron nuevos registros para la araneofauna mexicana. El estrato del sotobosque presentó la mayor riqueza de especies y el mayor número de individuos respecto al estrato del suelo, y hubo un alto recambio de especies, con solo 17% del total de especies compartidas entre estratos.

La araneofauna de El Triunfo muestra similitudes con otros BMMs (especialmente con uno de la misma cordillera) respecto a la identidad de las familias más ricas en especies y dominantes, así como en la composición de familias y géneros, la presencia y relevancia (en abundancia o riqueza) de familias que no son comunes en los hábitats tropicales de tierras bajas (Linyphiidae y Theridiosomatidae), y en la elevada proporción de especies no descritas. Sin embargo, se observó un alto recambio de especies entre sitios (solo 16% de especies compartidas), aún a distancias relativamente cortas, lo que parece ligado a proporciones relativamente altas de especies endémicas. Nuestros resultados sugieren que la alta abundancia de Theridiosomathidae y Linyphiidae, junto con la alta riqueza de especies de esta última familia, podrían ser empleadas como indicadores de conservación para los BMMs de México. El alto número de especies no descritas en los BMM analizados, y sus relativamente altos niveles de endemicidad, soportan la hipótesis de que los BMMs podrían ser considerados como posibles hotspot para el orden Araneae.

Resumen en inglés

We carried out an intensive and systematized sampling of the spider fauna of the tropical mountain cloud forest (TMCF) in El Triunfo Biosphere Reserve, Chiapas, Mexico, in order to analyze their composition, species richness, abundance, and proportion of undescribed species, and to compare these results with those found in other TMCFs. We sampled ten plots in two seasons (dry and rainy) using different sampling techniques on two strata (ground and understory). A total of 7,432 specimens were collected corresponding to 28 families, 78 genera and 111 morphospecies. A high proportion of total species (58.6%) were undescribed species. For 11 species originally described from a single sex, we found the other sex. Five species and one genus were new records for the Mexican spider fauna. Understory stratum had higher numbers of species and individuals than ground stratum, and there was a high species turnover, with only 17% of the total species shared between strata.

The spider fauna of El Triunfo shows similarities with other TMCFs (especially that on the same mountain range) concerning the identities of dominant and species-rich families, family and genera composition, the presence and relevance (in abundance or richness) of families that are uncommon in lowland tropical habitats (Linyphiidae and Theridiosomatidae), and in the high proportion of undescribed species. However, there is a high species turnover among sites (only 16% species shared), even at relatively short distances, that seems derived in part from the relative high proportions of endemic species. Our results suggest that high abundance of Theridiosomatidae and Linyphiidae, together with high species richness of this last family, could be used as conservation indicators for the Mexican TMCFs. The high numbers of undescribed species in the analyzed TMCFs, and their relatively high endemicity levels, support that TMCFs could be regarded as hotspots for the order Araneae.

Resumen en español

Las áreas naturales protegidas (ANP), por medio de su gestión, pueden funcionar como territorios que faciliten la capacidad de adaptación (CA) de sus habitantes. En este estudio se evaluó la influencia de un programa gubernamental ambiental (Procodes) sobre la CA de grupos comunitarios en un ANP. Para ello, se realizó una revisión documental del programa (2008-2016) y una encuesta de percepción en 2016 que comprende dimensiones social y ecológica. Acorde a los resultados, el fortalecimiento de la CA se relaciona con la legitimidad de los mecanismos de participación, la asignación de subsidios y el horizonte de planificación de proyectos productivos.

Resumen en inglés

Protected areas (PA), through management, can be territories that facilitate the strengthening of inhabitants’ adaptive capacity (AC). This work evaluated the influence of a governmental environmental program (Procodes) on the AC of community groups into PA. To this end, a documentary review (2008-2016) and a perception survey in 2016 were conducted that included ecological and social dimensions. According to the results, the strengthening of AC is related with legitimacy of participation mechanisms, the assignation of subsidies and the planning horizon of productive projects.
