“…These three species together constituted 68.4% of all individuals collected during two seasons. According BRagagnolo et al (2007), the abundance of Munequita sp. and Neosadocus maximus is not affected by quality of habitat nor fragment size of the forest in which they live.…”

“…There are no published data on this subject for Holcobunus nigripalpis. However, according BRagagnolo et al (2007) high dominance of a few Eupnoi species in a community can be associated with environments affected by high levels of human disturbance. The remaining species showed abundance more evenly distributed between the two seasons, with a small overall increase in summer.…”

“…The diversity of POP is closer to that of semi deciduous Atlantic Forest areas, like Serra do Japi (6.11). According to BRagagnolo et al (2007), communities of harvestmen are strongly affected by habitat fragmentation. In POP, the exploitation of wood for charcoal production within 50 years (the current vegetation is secondary) is probably the cause of low diversity.…”

“…II. Comparison among alfa diversity in several quantitatively inventoried localities of Atlantic Rain Forest and one Amazonian (E.N.S*, Effective Number of Species; sources: BRagagnolo et al, 2007 andBonaldo, 2006) Relation between abundance and richness with environmental parameters. Temperature and humidity are environmental factors that most influence the occurrence and habitat use by harvestmen (cuRtiS & Machado, 2007).…”

“…The standardization of sampling in harvestmen inventories began with Pinto-da-Rocha (1999). Sampling methodologies were best developed and used in subsequent work (BRagagnolo & Pintoda-Rocha, 2003;BReScovit et al, 2004;BRagagnolo et al, 2007). Finally, the work of Pinto-da- Rocha et al (2005) provides a detailed overview of the biological and geomorphological processes that formed the Atlantic rainforest itself, leading to the current spatial distribution of harvestmen within this biome.…”

Diversity of harvestmen (Arachnida, Opiliones) in Parque daABSTRACT. The environment most diverse in harvestmen species is the Atlantic Forest of São Paulo. However, there remains a lack of studies regarding their communities in certain regions. Among these regions is one south of the Paranapiacaba mountain range in the state of São Paulo, the Parque da Onça Parda (POP). Through nocturnal collections and pitfall traps, the region's harvestmen community has been studied. The observed richness of this site included 27 species, with dominance of three species: Holcobunus nigripalpis Roewer, 1910, Neosadocus maximus (Giltay, 1928 and Munequita sp., accounting for 68.4% of harvestmen abundance. This makes the diversity of POP more similar to the semideciduous Atlantic Forest communities of the interior than to those of the Coastal Atlantic Forest that contains the park. Its geographic location places it within the Southern São Paulo State (SSP) area of endemism, along with the Parque Turístico do Alto Ribeira (PETAR), with which it shares up to 12% similarity regarding harvestmen fauna. Richness and abundance of harvestmen were positively related to temperature and humidity. The period of animal activity (as measured by abundance and richness) varied throughout the night, being highest in the early hours during both studied seasons (summer and winter). KEYWORDS. Daddy longlegs, Alpha diversity, Atlantic Rain Forest.RESUMO. O ambiente mais diverso em opiliões é a Mata Atlântica paulista, no entanto ainda há carência de estudos sobre suas comunidades em determinadas regiões; uma delas é o sul da Serra do Paranapiacaba no estado de São Paulo, onde está o Parque da Onça Parda (POP). Através de coleta noturna e montagem de armadilhas de queda, estudou-se a comunidade de opiliões da região. A riqueza do parque é de 27 espécies, porém a dominância de três espécies (Holcobunus nigripalpis Roewer, 1910; Neosadocus maximus (Giltay, 1928) e Munequita sp., que perfazem 68,4% da abundância total de opiliões), torna a diversidade do POP mais semelhante com a região de Mata Atlântica Semidecídua do interior do que com as da Mata Atlântica Costeira, onde o parque está inserido. Sua localização geográfica o coloca dentro da área de endemismo do Sul de São Paulo (SSP), juntamente com o Parque Turístico do Alto Ribeira (PETAR) e Intervales, com quem possui uma semelhança na fauna de opiliões de 12%. Os opiliões responderam aos parâmetros ambientais, com abundância e riqueza positivamente relacionadas à umidade e temperatura. Por fim, o período de atividade desses animais (medida pela distribuição da abundância e da riqueza) parece ser bastante distinto ao longo da noite, sendo maiores nas primeiras horas, nas duas épocas do ano (verão e inverno).

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.
