“…In spite of the heterogeneous distribution of abundance and richness of Pseudoscorpiones among the different habitats, individual analyzes have not shown significant temporal variation in the distribution of these arachnids over the different seasonal periods. This is a different situation from that observed for other arthropod groups in the same region (Castilho et al, 2005;Battirola et al, 2007;2009;Battirola, Marques, Brescovit, Rosado-Neto, & Anjos, 2010;Marques et al, 2011). Although the Pseudoscorpiones constitute a very diverse group (Harvey, 2013) only 18 species were sampled, showing low species richness for this study area.…”

“…Mahnert & Adis, 2002), the knowledge about ecological and taxonomical diversity of pseudoscorpions is under explored, as well as their relationship with the different habitats. The Pseudoscorpiones are arachnids that can occupy a variety of terrestrial habitats, mainly edaphic and cave environments (Murienne, Harvey, & Giribet, 2008), and can colonize the forest canopy Adis, Mahnert, De Morais, & Rodrigues, 1988;Battirola, Adis, Marques, & Silva, 2007;Mahnert, 2009;Marques, Adis, Battirola, Santos, & Castilho, 2011), or live associated with the nests of social insects, birds and mammals (Mahnert & Adis, 2002). Estimates show that the order Pseudoscorpiones has 3 533 species worldwide (Harvey, 2013), although earlier projections had already estimated that the number was close to 5 000 species (Adis & Harvey, 2000;Adis, 2002).…”

Pseudoscorpions embrace a diverse group of arachnids with approximately 3 500 species that occur in various habitats, such as soil, leaf litter, caves and canopies. This study aimed at evaluating the relationship between the pseudoscorpion assemblages in soil, termite nests, tree trunks and canopies, as well as the temporal distribution as to the abundance and richness of species in these habitats. For this purpose different sampling techniques were applied in an integrated manner in distinct habitats of a seasonally flooded monodominant forest in the Northern Pantanal of Mato Grosso, Brazil. Data regarding the abundance and richness of assemblage species were organized by means of the Non-Metric Multidimensional Scaling (NMDS). A total of 2 068 Pseudoscorpiones distributed in seven families and 18 species were captured. Chernetidae (8 spp.) and Withiidae (5 spp.) predominated, while Atemnidae, Cheiridiidae, Geogarypidae, Lechytiidae and Olpiidae were present with only one species each. Terrestrial fauna was more abundant (1 035 ind.; 50.0 % of the total catch) with three families and 10 species. In the arboreal fauna (712 ind.; 34.4 %), four families and 13 species were found. Termite mounds (321 ind.; 15.6 %) corresponded to the habitat with the least number of individuals, however, five families and nine species were identified, including Parachernes sp. 2, Geogarypus sp. and Olpiolum sp., not found in other analyzed habitats in this forest. The analyses did not show any temporal variation as to abundance or richness of Pseudoscorpiones in each evaluated habitat; however, the analysis showed that the edaphic environment (soil + termite nests), tree trunks and tree canopies are distinct habitats in relation to the composition of the assemblage. The occurrence of typical terricolous (e.g. Parawithius sp., Withiidae gen. sp. and Parachernes sp.) and other arboricolous (e.g. Cheiridium sp., Americhernes sp. and Lustrochernes sp.) species highlights the vertical stratification of the assemblage present in this floodplain forest in the Pantanal of Mato Grosso.

ABSTRACT. Food used by two sympatric species of Moenkhausia (Characiformes, Characidae), in a stream of centerwestern Brazil. This study evaluated the seasonality in the diet of Moenkhausia dichroura (Kner, 1858) and M. sanctaefilomenae (Steindachner, 1907), sympatric species of the Cancela stream, state of Mato Grosso, Brazil. Regardless of the seasonal period, allochthonous food source predominated in the diet of both species (>50% of all items consumed) and among these terrestrial insects were the dominant resource. However, aquatic insects were important in the diet of M. dichroura as well. Hymenoptera (Formicidae) was the dominant item to both species, thus they were characterized as terrestrial insectivorous. The restricted diet of these species is confirmed by the trophic niche breadth, whose values were in general low: Ba=0.26 to M. dichroura in both periods and Ba=0.41 and 0.38 in the dry and rainy period, respectively, to M. sanctaefilomenae. The feeding overlap was high in the rainy period (O jk =0.75) and intermediate in the dry period (O jk =0.41), showing that the food partitioning between species was larger in this period. KEYWORDS. Diet, Moenkhausia dichroura, M. sanctaefilomenae, coexistence.RESUMO. Esse estudo avaliou sazonalmente a dieta de Moenkhausia dichroura (Kner, 1858) e M. sanctaefilomenae (Steindachner, 1907), coletadas em simpatria no riacho Cancela, Mato Grosso, Brasil. Independente do período hidrológico, alimentos de origem alóctone predominaram na dieta de ambas as espécies (>50% do total de itens consumidos), sendo insetos terrestres o recurso principal, embora, para M. dichroura insetos aquáticos tenham contribuído na dieta também. Hymenoptera (Formicidae) foi o alimento mais consumido, sendo ambas as espécies caracterizadas como insetívoras terrestres. A dieta restrita dessas espécies é confirmada pelos baixos valores de amplitude de nicho trófico: Ba=0,26 para M. dichroura em ambos os períodos e Ba=0,41 no período de seca e 0,38 no período de chuva, para M. sanctaefilomenae. A sobreposição alimentar foi elevada no período de chuva (O jk =0,75) e apresentou valor intermediário no período de seca (O jk =0,41), evidenciando maior partilha do alimento entre as espécies neste período.

“…Interception traps had not been previously used for a comprehensive estimate of invertebrates inhabiting the tree crown. The methodology used to estimate the whole invertebrate community in tree crowns (extrapolation of interception trap volume to the entire crown volume) might underestimate invertebrate richness and abundance by some orders of magnitude in light of other studies (e.g., Battirola et al 2007). This method may also overestimate insect abundance since it captures a small volume of invertebrates moving in the tree crown.…”

A field experiment links forest structure and biodiversity: epiphytes enhance canopy invertebrates in Chilean forests

et al. 2012

Abstract. Epiphytes represent a conspicuous component of the canopy of old-growth forests, reaching biomass values of up to 44 t/ha. Forest epiphytes host a rich invertebrate community; however, the contribution of epiphytes to the richness and abundance of canopy invertebrates is still quite unknown, and has not been experimentally assessed in old-growth forests. We studied the contribution of epiphyte loads to invertebrate species composition and abundance in the crown of large old individual trees of Eucryphia cordifolia (Cunoniaceae) in old-growth forests from southern Chile. We accessed the canopy using arborist techniques and contrasted the invertebrate species richness and biomass inhabiting four large canopy trees (25-30 m high, 1.2 m DBH), two of them with intact epiphytes and two trees from which epiphytes were manually removed. For over a year (April, 2006 to May, 2007 we made monthly collections of invertebrates from each tree's crown using flight-interception and eclector traps (the latter designed to capture walking invertebrates from trunks and limbs). Once every season we collected samples of epiphytes and their soil to quantify invertebrates using Berlese funnels. We found significantly greater invertebrate species richness and abundance in the control trees' crowns (with epiphytes) compared to the trees from which epiphytes were removed. Predators (such as spiders and centipedes) were disproportionately more abundant on trees with epiphytes, and an entire functional group (detritivores), associated with arboreal soils under the epiphytes, was absent in the trees from which epiphytes were removed. Invertebrate abundances were lower in winter and higher in summer for trees with epiphytes, while for trees without epiphytes invertebrate numbers fluctuated markedly, but with no seasonal pattern. We show that large old trees are an important structural component in forests, supporting additional structure represented by the epiphyte load, which, in turn, sustains a rich community of invertebrates with functional groups not otherwise present in the forest canopy. Our findings strongly recommend that forest managers retain large old trees with their epiphytes in order to sustain biodiversity and important ecosystem processes.
