“…Reductions could be more intense independently of taxonomic group in specialist species [34], therefore the conservation status of specialist species is likely to be modified under future scenarios. Projections of future habitat suitability have been tested in groups as diverse as ants [45] or ticks [23], and ecological niche models (ENMs), including climatic models [43], have proved to be efficient for making decisions regarding conservation priorities [32,54]. Such models are commonly used to assess impacts of future climatic warming, comparing distributions under current environmental variables with conditions under future projections for these same environmental variables [47].…”

One common approach to assigning conservation priorities during the current biodiversity crisis is to identify and direct efforts to high profile, vulnerable taxa, and important biodiversity areas. We addressed the first issue by assessing the comparison between conservation status and habitat suitability under differing climate change scenarios for sixteen species of five amphibian families (Pelobatidae, Bufonidae, Alytidae, Hylidae and Ranidae) distributed on both sides of the Gibraltar Strait, with the aim of verify whether potentially sensible species under climatic change scenarios are or not considered at risk presently in the IUCN current categories. We have addressed this with an environmental niche modelling algorithm (MaxEnt) and projecting the outputs in four future climatic change scenarios. Our results demonstrate that climatic niches of some species may currently match their conservation category, with Pelobates varaldii having the narrowest distribution and being the more endangered species, but not all responses to predicted climatic change scenarios are related to conservation status. Some suggest notable changes in potential climatic habitats, with both substantial increase (7 species) and decrease (5 species) represented. Threatened species such as P. varaldii could be climatically favored whereas currently more abundant species could maintain, increase, or reduce their habitat distribution. These results have implications for current conservation strategies, and suggest that this approach deserves consideration as part of any species or habitat conservation strategy in the future.

“…Taxonomic keys available in the literature were used for taxonomical determination botanical species. Two samples of leaves and strobiles were taken from each WS tree (Martínez 1992, Villers Ruíz et al 2006, Ramos-Dorantes et al 2017. Samples were housed in the National Herbarium (MEXU).…”

Background: In La Malinche National Park (LMNP), Pinus species are exploited mainly because they are a non-woody source of products such as ocote (resinous wood chips) and wood. Questions/Objective: Which Pinus species are subjected to wood-stripping (WS) in the LMNP? What are their dendrometric characteristics? Do WS trees present traumatic resin ducts associated with the ocoteo practice? Does the number of trees subjected to WS increase with altitude? Study site and dates: La Malinche National Park; Tlaxcala, México, 2017-2018. Methods: Random stratified sampling was done in a total of 33 plots in three different altitudes to quantify the number of damaged and undamaged trees and the total height and diameter per tree in each plot. Increment borers were obtained to estimate tree age, samples were taken for taxonomic determination, and tissue samples to evaluate mechanical damage. Results: Pine species subjected to wood-stripping (ocoteo) were P. leiophylla, P. montezumae, P. pseudostrobus, and P. teocote, with P. montezumae being the most affected in high and mid altitudes. WS trees were those with the greatest diameter and with the largest number of traumatic resin ducts. The species having the highest number of traumatic resin ducts was P. teocote. Conclusions: WS intensity in the LMNP is greater in the mid and low altitudes and in trees of greater diameter, height, and age. The species most affected by WS is P. montezumae and all WS individuals have a significantly higher number of traumatic resin ducts.

“…Las variables climáticas usadas fueron previamente seleccionadas con el coeficiente de correlación de Spearman (r < 0.8) (Dormann et al, 2013) (Tabla 2). La validez del modelo fue evaluado acorde a las curvas de respuesta (análisis de omisión/comisión) y sensibilidad Curva Operada por el Receptor (ROC)-Área Bajo la Curva (AUC) (Elith et al, 2006;Aguirre & Duivenvoorden, 2010) y pruebas Jackknife para medir el efecto de cada variable en el modelo (Hijmans et al, 2005;Ramos-Dorantes et al, 2017).…”

Las quinas o cascarillas (Cinchona L.: Rubiaceae) representan uno de los recursos vegetales emblemáticos de la flora peruana, debido a su uso como agente antimalárico y a la riqueza de especies ocurrentes en nuestro territorio andino. De las 23 especies reportadas en el mundo, Cinchona officinalis L. es una especie que es confundida con C. capuli L. Andersson, C. lancifolia Mutis y C. macrocalyx Pav. ex DC. por su similitud morfológica. El hábitat donde se encuentran estas especies corresponde a bosques montanos principalmente; y la mayoría está amenazada por el crecimiento urbano y la deforestación. Por esas razones, los objetivos del estudio fueron: esclarecer sus límites taxonómicos, corroborar la existencia de C. officinalis en el Perú, estimar su estado actual de conservación y analizar su hábitat potencial. Los resultados brindaron precisiones de los caracteres diagnósticos existentes en la literatura, a fin de distinguir a Cinchona officinalis de C. capuli, C. lancifolia y C. macrocalyx. La revisión de las exsicatas depositadas en herbarios y evaluaciones de campo, ha permitido confirmar su presencia en el Perú, específicamente en la región de Piura. Los 23 reportes de presencia, obtenidos hasta la actualidad, permitieron determinar la extensión de ocurrencia (EOO = 11 166.6 km 2) y el área de ocupación (AAO = 72 km 2), siendo ambos valores menores a 20 000 km 2 de EOO y 500 km 2 de AOO. Observaciones de campo evidenciaron que la quema y el crecimiento urbano fueron amenazas latentes para su hábitat. De este modo, se plantea que el estado actual de C. officinalis es En Peligro (EN) según los criterios de la IUCN (2012, Versión 3.1; 2017, Versión 13). Adicionalmente, su hábitat parece estar confinado a la parte alta de Piura y algunas pequeñas áreas limítrofes de Cajamarca según el algoritmo de Maxent (AUC = 997); y ello reflejaría el inicio de la ejecución de futuros planes de manejo sostenible y conservación.
