1. Update on the distribution of Aedes albopictus (Diptera: Culicidae) in Misiones, Argentina
ABSTRACT The Asian tiger mosquito ( Aedes albopictus, Diptera: Culicidae) has spread rapidly in the last 30 years from its native region in Southeast Asia. In Argentina, studies on its potential distribution suggest that this species could be found in temperate zones of the province of Buenos Aires. However, since its initial detection in 1998 Ae. albopictus

2. Updates on extratropical region climbing plant flora: news regarding a still-neglected diversity
ABSTRACT Most studies concerning climbing plants have focused on lianas, forest ecosystems, and tropical regions. Thus, the majority of existing information is not relevant to all climbing plants (lianas and vines) or all ecoregions of the world (forested and non-forested). We provide an update on floristic and distributional data available for climbing plan

3. Leaf proline content and its relation to fruit load and flowering in citrus under field conditions
Resumo Espécies de citros cultivadas em zonas temperadas têm brotação inibida no inverno, retornando na primavera quando elas também florescem. O principal fator que define o destino vegetativo ou reprodutivo das gemas é a presença de frutos em desenvolvimento. Baixas temperaturas no inverno retardam o metabolismo das plantas, que tem sido relatado c

4. Distribution of slipper lobsters (Decapoda: Scyllaridae) in Uruguayan waters
Abstract Scyllarid lobsters are commonly found in tropical waters with scarce records from temperate zones in the southwestern Atlantic. Here, we provide new information about the distribution of Scyllarides deceptor Holthuis, 1963 along the Uruguayan continental shelf and include a new austral record for Scyllarus depressus (Smith, 1881).

5. Climatic Variation: Effects on Stress Levels, Feed Intake, and Bodyweight of Broilers
ABSTRACT Chickens tolerate a very narrow range of climatic variation, and therefore, it is essential to determine the most suitable climatic area and weather for broiler production in open-house systems. In this study, 3060 broilers were used as experimental birds to investigate the effects of seasonal differences and climatic variations on the growth perfor

6. Habitat use and seasonal activity of insectivorous bats (Mammalia: Chiroptera) in the grasslands of southern Brazil
In temperate zones, insectivorous bats use some types of habitat more frequently than others, and are more active in the warmest periods of the year. We assessed the spatial and seasonal activity patterns of bats in open areas of the southernmost region of Brazil. We tested the hypothesis that bat activity differs among habitat types, among seasons, and is i

7. Distribution of the cladoceran Bosmina huaronensis Delachaux, 1918 and niche differentiation among populations from different biogeographic regions
Described from a high-altitude lake in Peru, Bosmina huaronensis Delachaux, 1918 has been recorded in diverse kinds of water bodies in South and North America, suggesting that this species has high environmental tolerance and a wide niche breadth. The present study surveyed the occurrence records of B. huaronensis from 55 localities and, using multivariate a

8. Species composition and abundance of the benthic community of Axiidea and Gebiidea (Crustacea: Decapoda) in the Marapanim Bay, Amazon estuary, northern Brazil
The thalassinideans (Axiidea and Gebiidea) encompasses approximately 615 species with reclusive habits, generally confined to extensive galleries burrowed into the sand or mud and, more rarely, in openings in reefs or the cavities of sessile animals such as sponges and coral. These species use the galleries for shelter, feeding and breeding, except during th

10. New fossil Stylops (Strepsiptera: Stylopidae) from Dominican amber
Description of a new species of the genus Stylops from Dominican amber expands the number of families of this order represented by fossils of the mid-Eocene in the Neotropical region. The specimen described herein is reasonably well preserved, except for the tip of the abdomen that hampered observation of the aedeagus. The specimen fits definition of the com

11. DISTRIBUIÇÃO ESPACIAL DE COLEÓPTEROS AQUÁTICOS EM POÇAS TEMPORÁRIAS RIPÁRIAS EM UMA FLORESTA DE TERRA FIRME NA AMAZÔNIA CENTRAL / Spatial distribution of water beetles in riparian temporary ponds in a terra firme forest in Central Amazonia
Temporary ponds are aquatic habitats that pass periodically a dry phase. They are inhabitated for several taxa, especially water beetles. Studies show that environmental factors and variations in physicochemical characteristics of water can influence the distribution of organisms that use temporary ponds. In this study, the effect of habitat structural featu

12. EFFECTS OF ATMOSPHERIC MULTIPATH IN LINE-OF -SIGHT MICROWAVE SYSTEMS / EFEITOS DE MULTIPERCURSOS ATMOSFÉRICOS EM ENLACES DE MICROONDAS EM VISIBILIDADE
The variations which happen in the troposphere layers throughout the time in relation to the median condition of the signal cause various phenomena that change the received signal level at digital radio relay systems randomly. The random changes are named fading. Fading is normally classified as fast or slow. The former is normally associated with the atmosp
