Record of aquatic invertebrates associated with the bromeliads Aechmea ornata (Baker) and Aechmea recurvata (Klotzsch) L. B. Sm in two Atlantic Rainforest fragments of south Brazil

Abstract: Bromeliads are numerous both in diversity and abundance in the Atlantic Rainforest, one of the most threatened biomes on Earth. They are also an important habitat for several animal species that live in the water retained by its rosette structure. In this study, we aimed to characterize and compare the macroinvertebrate community of two bromeliad species from Atlantic forest fragments. One is characteristic of Dense Ombrophilous Forests, Aechmea ornata, and the other occurs in Mixed Ombrophilous Forests, Aechmea recurvata. We sampled and identified macroinvertebrates form 24 bromeliads, 12 of each species. A total of 19 taxa and 656 specimens were sampled. In both bromeliad species, Diptera was the most abundant insect order (n=417), represented mostly by mosquitoes (n=227) and non-biting midges (n=107), followed by Scirtidae marsh beetles (n=216). Aechmea ornata presented higher abundance and lower invertebrate richness compared to Aechmea recurvata. Seven taxa were exclusive of A. recurvata, eight were common to both, and four, including a sponge, occurred only in A. ornata. The most abundant invertebrate taxa were common to both bromeliads and are regarded as typical of lentic environments. On the other hand, the high number of exclusive species indicates that conservation efforts should include bromeliads from these two phytophysiognomies to secure protecting the diversity of phytotelmata communities.

Wild birds have an important role in the epidemiology of tick-borne diseases, serving as reservoirs for some tick-borne diseases and in the maintenance and dispersion of ticks. During the years of 1999, 2000 and 2001, birds were captured in three Atlantic forest fragments of the state of Paraná. Overall, 1,122 bird specimens of 36 species were captured. Of these, 80 (7.1% prevalence) birds were parasitized by ticks, comprising females of Ixodes paranaensis Barros-Battesti, Arzua, Pichorim & Keirans, and immature stages of Amblyomma calcaratum Neumann, Amblyomma longirostre (Koch), Amblyomma aureolatum (Pallas), Amblyomma ovale Koch, and Amblyomma parkeri Fonseca & Aragão. Two nymphs were identified as Amblyomma sp., although their external morphology was very similar to the A. parkeri nymph. This study provides new tick-host records for the state of Paraná and for Brazil.

Eugenia uniflora L. (Myrtaceae) is pollinated mostly by bees and there are no restrictions for pollen collection in their flowers. This stimulated us to study the bee diversity on its flowers in two forest fragments in southern Brazil, in August and September, 2012. A total of 826 bees belonging to 39 species and four subfamilies were captured with entomological nets. Halictinae presented the greatest richness, followed by Apinae, Colletinae and Andreninae. Apis mellifera was the only common species and the most abundant, followed by Scaptotrigona bipunctata and Melipona obscurior. Seven species were classified as intermediate and 31 as rare. Highest numbers of bees were collected from 10h to 11:30, and The species richness of flower visiting bees was much higher than that of previous studies with first records of Plebeia remota and Anthrenoides paolae. Eugenia uniflora is a food source for exotic and native bees and possibly contributes to the conservation of these bees in forest fragments. In return, the bees probably act in maintaining this plant native of the Atlantic Forest.

Os anéis de crescimento de Cedrela fissilis foram analisados em duas unidades fitogeográficas do estado do Paraná, em áreas de Florestas Ombrófilas Densa e Mista, litoral e planalto, no domínio da Floresta Atlântica, buscando encontrar sinais climáticos nas séries radiais temporais de anéis de crescimento. As áreas não apresentam estação seca bem definida, com precipitações bem distribuídas ao longo do ano. Na área do litoral, as temperaturas são altas e constantes durante todo o ano, enquanto que na área do planalto as temperaturas são mais amenas, ocorrendo considerável variação durante o ano. Nas duas áreas foram coletadas 3-4 amostras radiais dos indivíduos selecionados, sendo 15 no litoral e 21 no planalto. Os anéis de crescimento foram marcados, mensurados, submetidos ao controle de qualidade por meio do programa COFECHA® e as cronologias foram geradas utilizando o programa ARSTAN®. Sinais climáticos nas séries foram identificados utilizando-se Correlações de Pearson. As séries analisadas provenientes da área de planalto apresentaram melhores correlações com as variáveis temperatura e precipitação, sendo identificados sinais climáticos, enquanto que as séries do litoral não puderam ser datadas com total acurácia. É atribuída a hipótese da competição, principalmente por luz, para explicar a dificuldade na datação dos indivíduos do litoral.Palavras-chave: Anéis de crescimento; dendrocronologia; Floresta Atlântica. AbstractClimatic signals in growth rings of Cedrela fissilis in different types of South Brazil rainforests. Cedrela fissilis tree-rings were examined in two distinct phytogeographic units of the State of Paraná, Brazil. The analysis was carried out in areas of tropical rain forest, Atlantic Forest (cost), and Araucaria Forest (plateau) in order to seek for climatic signals in tree rings series. In the coast area, temperatures are high and constant throughout the year, while in the area of the plateau, temperatures are milder and considerable variations occur during the year. In both areas 3-4 radial samples of each selected individual were collected, 15 from the coast and 21 from the plateau. Growth rings were marked, measured, submitted to quality control using the COFECHA® software, and chronologies generated using the ARSTAN® software. Climatic signals in growth rings were identified using Pearson correlations. Tree rings series from plateau revealed better correlations with temperature and rainfall compared to the coast ones; they were accurately dated while the other from coast could not be dated with accuracy. Climatic signals were found in the well-dated chronology. The hypothesis of competition, mainly by light, is raised to explain the difficulty to establish a good chronology for coast area.Keywords: Growth rings; dendrochronology; Atlantic Forest.

The vegetation may modifies the structure and composition of the community of edaphic arthropods. This study aimed to compare the community of edaphic arthropods in four areas of abandoned pasture (AP1, AP2, AP3, AP4) and four secondary native forest fragments in a successional gradient (FF1, FF2, FF3, FF4), in Itaboraí, Rio de Janeiro, Brazil. The areas are positioned on the hillside and the sampling was conducted in transects outlined in a toposequence (upper, middle and lower sections), where pitfall traps were installed in the dry season. The organisms were identified in taxonomic groups (class, order and family). Comparing the averages for AP and FF, there was no defined pattern in terms of the response of structural attributes (total abundance, richness, uniformity and diversity). Among the areas of FF, higher values of all of the structural attributes occurred in the intermediate stages of forest succession (FF2, FF3), compared to the initial (FF1) and advanced stages (FF4). On average for the FF, the most favored groups were Archaeognatha, Coleoptera, Entomobryomorpha, Pseudoscorpionida, Psocoptera and Symphypleona. On average for the areas of AP, the most favored groups were Acari, Araneae, Formicidae, Diplopoda and Auchenorrhyncha. Among the areas of FF, Sternorryncha, Symphyla and Thysanura were favored in FF1, while Coleoptera, Psocoptera, Pseudoscorpionida, Entomobryomorpha and Archaeognatha were favored in the other successional stages (FF2, FF3, FF4

The Matrix

Abstract: Forest fragments in the state of Minas Gerais contain a large number of Bromeliaceae genera, whose cisterns accumulate water and organic matter, providing shelter and food for a wide range of organisms. However, these fragments often consist only of small patches of vegetation, making the species more vulnerable to the effects of this landscape changes. This study aimed to test the effect of the distance to the edge and of the matrix type on the structure of aquatic invertebrate communities in four morphospecies of bromeliads. Samples were collected in Atlantic Forest fragments adjacent to pasture and planted forest areas, in a region of Serra da Mantiqueira, Brazil. Of the 147 bromeliads investigated, we found 35 taxa, among which the most abundant groups were Ostracoda (4,962 individuals), Culicidae (2,358), Tanypodinae (1,164) and Scirtidae (1,043). The richness of taxa and Shannon diversity of invertebrates were similar at different distances from the edge, with variation of richness between 17 and 23 taxa and diversity between 1.25 and 1.52. The composition of the fauna in the cisterns changed between some collection sections (A vs. C, C vs. D and D vs. F), irrespective of being close to or far from the edge. There was no variation of richness (t=-1.145, df=106, p= 0.341) and diversity (t= 1.376, df= 106, p= 0.429) among samples collected from fragments next to planted forest and pasture, likely because the bromeliads studied were located on hillsides above the canopy of planted forests, and subject to similar conditions to those found in the fragments next to pastures. The results demonstrate the importance of bromeliads in maintaining the richness and diversity of the invertebrates they harbor, even in altered landscapes exposed to extreme conditions such as fragment edges.

AbstractSpecies that live in degraded habitats often show signs of physiological stress. Glucocorticoid hormones (e.g., corticosterone and cortisol) are often assessed as a proxy of the extent of physiological stress an animal has experienced. Our goal was to quantify glucocorticoids in free-ranging small mammals in fragments of Interior Atlantic Forest. We extracted glucocorticoids from fur samples of 106 small mammals (rodent genera Akodon and Oligoryzomys, and marsupial genera Gracilinanus and Marmosa) from six forest fragments (2–1200 ha) in the Reserva Natural Tapytá, Caazapá Department, Paraguay. To our knowledge, this is the first publication of corticosterone and cortisol levels for three of the four sampled genera (Akodon, Oligoryzomys, and Marmosa) in this forest system. We discovered three notable results. First, as predicted, glucocorticoid levels were higher in individuals living withing small forest fragments. Second, animals captured live using restraint trapping methods (Sherman traps) had higher glucocorticoid levels than those animals captured using kill traps (Victor traps), suggesting that hair glucocorticoid measures can reflect acute stress levels in addition to long-term glucocorticoid incorporation. These acute levels are likely due to urinary steroids diffusing into the hair shaft. This finding raises a concern about the use of certain trapping techniques in association with fur hormone analysis. Finally, as expected, we also detected genus-specific differences in glucocorticoid levels, as well as cortisol/corticosterone ratios.
