Temporal shifts in a Xylaria assemblage (Ascomycota, Xylariaceae) resulting from management activities in a protected cloud forest

Background and Aims: Tropical montane cloud forest (TMCF) is one of the most threatened ecosystems worldwide. Natural protected areas (NPAs) have been established to prevent further loss of these forests in Mexico. To assess whether management activities temporally impact the biodiversity of NPAs, t...

description Background and Aims: Tropical montane cloud forest (TMCF) is one of the most threatened ecosystems worldwide. Natural protected areas (NPAs) have been established to prevent further loss of these forests in Mexico. To assess whether management activities temporally impact the biodiversity of NPAs, the use of indicator groups, such as some groups of macromycetes, has been proposed. The aim of this study was to assess the temporal shifts over the last 36 years in the alpha, beta, and gamma diversity of a Xylaria assemblage in a NPA of TMCF as a result of anthropogenic management activities.Methods: Collections were performed in a 31 ha NPA of TMCF in Xalapa, Veracruz, Mexico, during three 10 year and one six year sampling periods (1980-2016), taking into account specimens deposited in the herbarium XAL and collections performed by the authors, mainly in the two latter periods. Species number and abundance, compositional similarity, species turnover, and gamma diversity of assemblages were determined and compared among the sampling periods.Key results: Of 3480 individuals belonging to 30 Xylaria species, the most abundant species were X. scruposa, X. anisopleura, X. berteroi, X. cubensis, X. feejeensis, X. albocinctoides, and X. arbuscula. The inventory completeness was 99.9%. Species richness varied from six (1990-1999) to 28 species (2010-2016). Jaccard index separated two assemblage clusters. Gamma diversity was more influenced by beta diversity than alpha diversity.Conclusions: Xylaria assemblages are a useful bioindicator group and monitoring them over time may provide information about the impacts of management on TMCF ecosystems. Temporal dynamics of these assemblages partly depend on the historically implemented management in the NPA of TMCF. Effective conservation outcomes for TMCF will only be achieved if current management strategies are maintained and integrated into the long-term management framework of NPAs containing TMCF.

Antecedentes y Objetivos: El bosque mesófilo de montaña (BMM) es uno de los ecosistemas más amenazados mundialmente. Las áreas naturales protegidas (ANP) han sido establecidas para prevenir la pérdida de estos bosques en México. Para evaluar el impacto temporal de las actividades de manejo de las ANP sobre la biodiversidad, se ha propuesto utilizar bioindicadores, como algunos grupos de macromicetos. El objetivo de este estudio fue evaluar los cambios temporales, durante los últimos 36 años, en la diversidad alfa, beta y gama de un ensamblaje de Xylaria en un ANP de BMM como un resultado de las actividades de manejo antropogénico.Métodos: Las recolectas fueron realizadas en un ANP de 31 ha de BMM en Xalapa, Veracruz, México, durante tres periodos de muestreo de 10 años y uno de seis (1980-2016), considerando ejemplares depositados en el herbario XAL y recolecciones realizadas por los autores principalmente en los últimos dos períodos. La riqueza, abundancia, similitud, recambio y la diversidad gama de los ensambles fue determinada y comparada entre periodos de muestreo.Resultados clave: De 3480 individuos pertenecientes a 30 especies de Xylaria, las más abundantes fueron X. scruposa, X. anisopleura, X. berteroi, X. cubensis, X. feejeensis, X. albocinctoides y X. arbuscula. La integración del inventario fue de 99.9%. La riqueza varió de seis (1990-1999) a 28 especies (2010-2016). El índice de Jaccard separó dos agrupaciones. La diversidad gama estuvo más influenciada por la diversidad beta que por la alfa.Conclusiones: Los ensamblajes de Xylaria son bioindicadores útiles y su monitoreo temporal puede proveer información del impacto del manejo del BMM. La dinámica temporal de estos ensamblajes depende parcialmente del manejo implementado históricamente en el ANP de BMM. La conservación eficiente del BMM dependerá del mantenimiento de las estrategias de manejo actuales y su integración a un plan de manejo a largo plazo del ANP que contiene BMM.
