The apifauna of an araucaria forest in southern Brazil was studied during 2001 – 2003, using entomological nets on flowering plants. A total of 2,749 individuals were sampled from five subfamilies and 93 species of bees. A total of 82 species with up to 10 individuals were sampled and 29 species had no distribution for Santa Catarina. Non-corbiculate Apidae and Halictidae species predominated as well as individuals of corbiculate Apidae and Halictidae. There was a decrease in species richness in cold seasons, being then sampled only Augochloropsis sp. 01, Augochloropsis sp. 10, Exomalopsis tomentosa, Neocorynura aenigma, Paroxystoglossa brachycera, Trigona spinipes and Apis mellifera. A bivoltine pattern was noticed, with a peak in May and in September-November, for richness and abundance. Ecological indexes over the months were different with and without A. mellifera. The bee accumulation curve remained in elevation until the end of sampling. The richness estimators indicated values of 142 and 175 species. The bee species were sampled on 125 species of plants of 40 famillies and the most visited were Asteraceae, Fabaceae/Solanaceae, Euphorbiaceae/Lamiaceae, Malvaceae/Rosaceae and Commelinaceae/Cucurbitaceae/ Liliaceae/Verbenaceae. A total of 48 species of plants characteristics of araucaria forests were sampled.

Abstract Crepuscular period is one of the factors that may influence the biting activity of mosquitoes. Many of these insects have a peak activity in this period. The purpose of this study was to investigate the afternoon crepuscular activity of Culicidae in a remaining area of Atlantic Forest in western Santa Catarina, southern Brazil. Moreover, the possible influence of abiotic factors, the abundance and species richness were verified. In order to better analyze the influence of crepuscular period in specific composition and abundance of mosquitoes, the dusk was divided into three periods: pre-sunset, sunset and post-sunset. At the end of the study, nine hundred and eight four specimens distributed in 12 genera and 23 species were collected. Trichoprosopon pallidiventer (Lutz, 1905) (59.76%), Aedes crinifer (Theobald, 1903) (8.13%), Ae. scapularis (Rondani, 1848) (5.89%) were the most abundant species. Spring time presented the greatest abundance and species richness. During the study, among the three periods evaluated, pre-sunset had the greatest abundance and post-sunset the lowest. Pre-sunset and sunset had the greatest similarity between species. Regarding to the abiotic factors evaluated seven and 15 days before sampling, they did not present significant correlation for the three most abundant species. However, temperature had a positive correlation to these species. Moreover, the correlation between collected species and its possible role as vectors of etiological agents of diseases was discussed.

The first studies of Leptophlebiidae in the Santa Catarina State, Southern Brazil, dated from 1920. Since then, not much is known about the family (even to the Order Ephemeroptera) to the State. The main goal of this study was to survey fauna of Leptophlebiidae in the Santa Catarina State based on nymphs. The material was obtained from the collection deposited at the Laboratório de Pesquisa em Ecologia e Química of the Universidade Comunitária da Região de Chapecó, besides additional specimens collected between 2008 and 2009. Occurrences were plotted in the hydrograph map of Santa Catarina State, with one map for each genus. The Leptophlebiidae nymphs were recorded in 26 aquatic environments that included small streams and rivers. We identified 24 morphotypes distributed in 12 genera. Number of genera in the Western of Santa Catarina increased from eight to 15. Thraulodes, Ulmeritoides and Homothraulus presented higher frequency of occurrence in the region. Leentvaaria and Hermanella were associated to regions well conserved such as in the Araucaria forest. Needhamella and Segesta were related mainly to Irani River.

Palynological Study

Palynology of peaty sediments from the high course of Cará Brook Creek, Coxilha Rica, Santa Catarina, Brazil. This paper presents the results of the palynological study of a sedimentary core collected in a bog in the upper part valley of Cará Brook Creek, in the cultural territory of Coxilha Rica, located in the Campos Gerais Plateau in Santa Catarina, Southern Brazil. The base of the core was dated in 6.900 14C years BP (7,845–7,690 cal years BP). The identification of the palynomorphs and the cluster analysis made possible to define two distinct palynological phases, despite the predominance of grassland vegetation throughout the whole core. From 34 cm, the frequency of bryophytes decreases, accompanied by the increase of the diversity of all vegetal taxa. Throughout the core, the most frequent families are Poaceae, Cyperaceae Apiaceae. The results indicate that the landscape of the upper course of the Brook Creek was characterized by grasslands from 6,900 14C years BP under a regional and humid climate, with a temperature increase in the historical period. Keywords: Middle Holocene, palynomorphs, grasslands, Araucaria forest, Highland.

The Atlantic Forest is the home to a diverse and threatened fauna of amphibians. However, knowledge on these species is still scarce to many of its ecosystems, such as the Seasonal Forest. This study was aimed at determining the diversity of anurans in Parque Estadual Fritz Plaumann (PEFP), located in the municipality of Concórdia, Santa Catarina, southern Brazil. The PEFP comprises 741 ha, and is the only Conservation Unit of Seasonal Forest in Santa Catarina state. From August 2010 to July 2011 we surveyed frogs fortnightly during four to ten days, from sunset until approximately midnight. Active, audio and visual searches were carried out at breeding sites and favorable areas to meet the species. The sampling effort of the survey was evaluated with species accumulation curve considering the field expeditions as sample units. The species composition of PEFP was compared with 16 other different vegetal formations of the Atlantic Forest biome through similarity analysis. Twenty-three species were recorded. The accumulation curve approached an asymptote, indicating that most species of the area were observed. Most species were observed in lentic habitats of open areas. The anuran species composition of PEFP was similar to other areas of Mixed Ombrophile Forest and Seasonal Forest in southern region. Although PEFP comprised a relatively small area, the occurrence of habitat specialists, endangered amphibians that dependent on the forest, indicates the importance of this area for the conservation of the regional fauna. The continuation of long-term standardized studies is needed to monitor the population dynamics of recorded species and support alternative management practices, aiming at the conservation of anurans at the Seasonal Forest.

Abstract Aims Assessing the role of a dominant native bamboo species on tree species diversity and structure in the medium term. Methods Over a 7-year period, we studied the natural regeneration of two dominant forest types in Southern Brazil (Araucaria Forest or AF; Bamboo Forest or BF) after a bamboo (Merostachys skvortzovii Send.) die-off between 2004 and 2006. The study was carried out in the Embrapa Research Station in Caçador, Santa Catarina State, Brazil. Important Findings The die-off provided ideal conditions for the establishment of several species and it kickstarted forest succession dynamics, which in turn affected regeneration diversity. Tree species richness was relatively stable with a transitory increase between 2007 and 2014 in both AF and BF. However, species richness rose in BF because of a relative increase in abundance of some species (especially late and secondary species) while a plunge in some pioneer species drove an increase in diversity. Overall, we found that BF has a lower diversity of recruits and that density declined over time, while AF is more diverse, with a more stable density. In BF, the bamboo die-off created optimal conditions for initial regeneration development (mainly fast-growing pioneer trees), which quickly transited to higher size classes. Yet, after this initial stage of pioneer recruitment, the number of recruits dropped followed by a virtual absence of growth regardless of the species group as a result of a quick bamboo reestablishment. As bamboo recreated a dense understory it reduced species diversity to original levels, suggesting a self-maintaining cycle that halts forest succession. On the other hand, the bamboo die-off had little impact on AF where a slow recruitment process typical of old-growth forests was observed. The results indicate that the die-off event had a temporary effect on species diversity i.e. restricted to forests where bamboos are dominant in a similar process described in other southern South American forests. As the first study to observe the medium-term forest dynamics related to bamboo die-off, we can conclude that when being dominant, native bamboos can hinder forest regeneration, maintaining lower levels of diversity and arresting forest succession that lasts well beyond the short-term, post-die-off effects. Many forest fragments in the region are dominated by bamboos, thus their potential for conservation is at risk and requires appropriate management.

Abstract Myrceugenia mesomischa (Burret) D. Legrand & Kausel (Myrtaceae), a tree species poorly cited in floristic and phytosociological surveys in its area of known occurrence, was recorded as one of the species with the highest importance value in a fragment of Araucaria forest in São Francisco de Paula municipality, Rio Grande do Sul state, Brazil. The species was abundant in the understory strata of the forest, showing the highest frequency and density of the survey. Considering the paucity of data on the species, its degree of rarity and endemism (occurring only in the states of Rio Grande do Sul and Santa Catarina, Brazil), more studies are needed to evaluate the true current state of conservation of populations of this species.
