Hyphomycetes AcuĂĄticos en Chile: estudio en el Estero de Limache; un afluente del RĂo Aconcagua
Mediante toma de muestras seriadas efectuadas en el transcurso de un año, se estudia la presencia de Hyphomycetes acuĂĄticos aplicando la tĂ©cnica de filtrado de las aguas segĂșn el mĂ©todo de lqbal y Webster (1973).Se contabilizaron los conidios de hongos acuĂĄticos y algunos terrestres, junto a las diatomeas retenidas en los filtros, analizando cualitativa y cuantitativamente los resultados con algunas variables del medio ambiente tales como: OxĂgeno disuelto, Nitratos, Amonios, Temperatura, Pluviosidad y efectos estacionales.Se detectaron formas conidiales correspondientes a 13 gĂ©neros y 20 especies de Hyphomycetes acuĂĄticos. Las especies dominantes fueron: Alatospora acuminata lngold, Flagellospora penicillioides lngold, Tetracladium marchalianum de Wild, Trisc      ophorus monosporus lngold y Triscelophorus sp. C
MASTREE+ : time-series of plant reproductive effort from six continents
Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series data from across the globe and makes these data freely available to the community. MASTREE+ includes 73,828 georeferenced observations of annual reproduction (e.g. seed and fruit counts) in perennial plant populations worldwide. These observations consist of 5971 population-level time-series from 974 species in 66 countries. The mean and median time-series length is 12.4 and 10 years respectively, and the data set includes 1122 series that extend over at least two decades (â„20 years of observations). For a subset of well-studied species, MASTREE+ includes extensive replication of time-series across geographical and climatic gradients. Here we describe the open-access data set, available as a.csv file, and we introduce an associated web-based app for data exploration. MASTREE+ will provide the basis for improved understanding of the response of long-lived plant reproduction to environmental change. Additionally, MASTREE+ will enable investigation of the ecology and evolution of reproductive strategies in perennial plants, and the role of plant reproduction as a driver of ecosystem dynamics
