“…However, some groups like Diptera and Coleoptera presented higher abundance values in the forest environment. These results were also found by Medri and Lopes (2001), and appear to be related to the favorable microclimatic conditions and to a greater resource demand.…”

Ecosystem Disturbances and Diversity Increase: Implications for Invertebrate Conservation

The Pantanal is one of the faunistic provinces considered as a priority area for invertebrate conservation. However, it is one of the areas in Brazil where the local fauna is less assessed, thus needing more scientific information that could allow political decisions to be made regarding conservation. The continuous pressure for new pasture areas leads to improper habitat occupation and destruction, like fragmentation of forest areas in the region. Such alterations can cause different impacts on the local fauna, including the soil arthropods. The main objective of this work was to compare the morphospecies composition, diversity and density of the soil arthropod fauna between a secondary single species forest (Cambarazal) and a cultivated pasture with exotic and native grass species, using only pitfall traps as sampling method. We found a great variation on the vegetal cover among environments. A higher humidity in the forest soil was observed, as well as a greater compaction of the soil in the cultivated pasture. A total of 3635 individuals were collected, belonging to 214 different morphospecies. 139 morphospecies were collected in the forest (37% exclusive to this environment), while 134 morphospecies were collected in the cultivated pasture (35% exclusive). The diversity was higher in the forest (H¢ = 1.634) than in the cultivated pasture (H¢ = 1.253). However, considering the area as a whole (forest and pasture) the global diversity was increased. In this paper we discuss about the effects of environmental changes on soil arthropod diversity and propose a hypothetical model for invertebrate management in mosaic ecosystems.

“…O Estado do Paraná sofreu uma grande devastação de sua cobertura vegetal nativa e, atualmente, apresentase apenas com alguns fragmentos remanescentes de florestas circundadas por terras cultivadas ou áreas de pastagens (MEDRI & LOPES, 2001a). As condições ambientais em uma floresta são bastante diferentes das de uma área aberta; a destruição dos ambientes naturais para a criação de pastagem ou monoculturas provoca alterações nos fatores abióticos, ocasionando mudança na estrutura e composição das comunidades, que podem sofrer perda de espécies não-adaptadas às novas condições ambientais (MEDRI & LOPES, 2001b).…”

ABSTRACT. Composition and diversity of Scarabaeoidea (Coleoptera) attracted by light trap in the rural areas of Northern Paraná. The most devastated environments in the State of Paraná are those with great agricultural potential, and most human interference actions on the environment are seldom preceded by a careful study of the fauna, which would reveal the diversity and abundance of animals in these areas. This study aimed to describe the Scarabaeoidea fauna attracted by light traps in rural areas of the Tamarana County, Paraná, Brazil, and to contribute to the ecological knowledge on species of this group. The sampling was carried out quarterly, from March 2002 to April 2003, in two rural properties, using a modified "Luiz de Queiroz" light trap. The light traps captured 2447 specimens, distributed into 10 families, 24 genera and 67 species. The three most abundant species were also the most frequent: Aphodius lividus (Olivier, 1789), Melolonthidae sp. 1 e Ataenius sp. 5. The highest A. lividus population density occurred in April, fall season, whereas Melolonthidae sp. 1 and Ataeucus were most frequently found in Octubre and November, spring. The majority of the species were represented by few individuals (H'= 1,74), and the distribution of individuals species was relatively uniform (J'= 0,95; S=0,20). A large number of families was recorded, and they were represented by few individuals. There was a predominance of families of detritivores -Aphodiidae, Scarabaeidae, Hybosoridae and phytophagus -Melolonthidae, Dynastidae and Rutilidae. The study collected 25 detritivore species among the 1422 specimen recorded.KEYWORDS. Scarabaeidae, diversity, rural area, light trap. PALAVRAS-CHAVE.

ResumenSe evaluó la artropofauna terrestre en Pari y Ondores en la Reserva Nacional de Junín, Perú utilizando: (1) trampas de caída de suelo, y (2) trampa de luz ultravioleta. Para la artropofauna, se calculó la diversidad alfa y beta. La artropofauna terrestre capturada fue adjudicada a gremios alimentarios. Se encontraron nueve familias. Las trampas de suelo con carnada atrajeron mayor cantidad de individuos, siendo más frecuentes los insectos del orden Collembola. El nivel trófico predominante fue los descomponedores. Se concluye que la evaluación rápida de biodiversidad (ERB) en la Reserva Nacional de Junín es relativamente baja para la artropofauna terrestre. Palabras claves: biodiversidad, collembola, conservación, insectos, Lago Junín Abstract Terrestrial arthropofauna at Pari and Ondores, at the Junín Natural Reserve, Peru, was assessed using: (1) pit fall traps and (2) ultraviolet light-traps. For arthropofauna, alpha and beta diversity were calculated. Terrestrial arthropofauna captured were assigned to trophic guilds. Nine families were found. The soil traps with carcass captured the highest quantity of specimens, with Collembola Order as the most frequent. Decomposer's level was the most predominant. We conclude that rapid biodiversity assessment (RBA) at the Junín National Reserve is relatively low for terrestrial arthropofauna.
