ABSTRACT
Background: This database gathers 10,721 specimens, belonging to 2,578 species from the Chilean vascular flora (angiosperms, gymnosperms and pteridophytes) deposited in the Herbarium of the Pontificia Universidad Católica de Valparaíso (PUCV) in Chile. The PUCV botanical collection was started by the renowned botanist Otto Zöllner and represents a major natural historical legacy for central Chile, with decades of information represented through preserved specimens. This collection is currently deposited in the Curauma campus of the PUCV. This digitisation effort is part of the PUCV's endeavour to mobilise its biological collections and make them freely available through GBIF, encouraging national and international researchers to generate new knowledge, based on this invaluable heritage, which is a silent witness of the vast plant diversity that once existed in Chile and that is now vanishing due to anthropogenic drivers. New information: The database provides occurrence records from 10,721 specimens of vascular flora held in the PUCV Herbarium, representing 2,578 species, 914 genera and 177 families. Each record includes data on taxonomy, geographic distribution, elevation and collection information (e.g. date of collection, legitimavit and determinavit of specimens, general observations). The database serves as a repository containing records from past decades on the diversity and distribution of plant species, mainly from the Chilean Mediterranean biodiversity hotspot.
ABSTRACT
Bees are a diverse group of insects that have tremendous importance as pollinators. In recent decades, there has been a global decline in bee populations because of land-use change, intensive agriculture, and climate change. Unfortunately, our knowledge of native bees' ecology is rather scarce, and such knowledge gaps are also a major threat to its conservation. In this sense, biological collections are a priceless natural history legacy and an information source for new research and decision making. Chile has a remarkable bee diversity, with 464 species currently known from Chile and a high incidence of endemism and a variety of habitats (including the Mediterranean biodiversity hotspot). The largest wild bee collection in Chile is held at the Pontificia Universidad Católica de Valparaíso (comprising a century of data). This collection has been recently included in GBIF. Here we present a database with 36,010 records, including information on sociality and ecology (including information on floral visitation range, the resource collected, and nesting substrates) for 160 out of the 167 bee species included (36% of the Chilean bee diversity, including 49 genera and five families). All records have the taxonomy resolved, and 83% of them have geographic coordinates, covering a latitudinal range between 18° S and 53° S from the continental and insular territories. This data set is released for noncommercial use only.
