Severe population decline of marsh deer, Blastocerus dichotomus (Cetartiodactyla: Cervidae), a threatened species, caused by flooding related to a hydroelectric power plant. Repositório Alice
ANDRIOLO, A.; PIOVEZAN, U.; COSTA, M. J. R. P. da; TORRES, H. A.; VIGLIOTTI, A.; ZERBINI, A. N.; DUARTE, J. M. B..
Balancing power production and environmental conservation can be problematic. The objective of this study was to investigate the abundance of marsh deer in the Paraná River Basin, above the Sergio Motta (Porto Primavera) Dam, before and after the impact of the dam closure. A fixed-wing, flat window aircraft was used to survey study transects. Observations were recorded based on the distance sampling line transect method, assuming that the detection probability decreases with increased distance.

NEON terrestrial field observations: designing continental-scale, standardized sampling. Repositório Alice
KAO, R. H.; GIBSON, C. M.; GALLERY, R. E.; MEIER, C. L.; BARNETT, D. T.; DOCHERTY, K. M.; BLEVINS, K. K.; TRAVERS, P. D.; AZUAJE, E.; SPRINGER, Y. P.; THIBAULT, K. M.; MCKENZIE, V. J.; KELLER, M.; ALVES, L. F.; HINCKLEY, E-L. S.; PARNELL, J.; SCHIMEL, D..
Rapid changes in climate and land use and the resulting shifts in species distributions and ecosystem functions have motivated the development of the National Ecological Observatory Network (NEON). Integrating across spatial scales from ground sampling to remote sensing, NEON will provide data for users to address ecological responses to changes in climate, land use, and species invasion across the United States for at least 30 years. Although NEON remote sensing and tower sensor elements are relatively well known, the biological measurements are not. This manuscript describes NEON terrestrial sampling, which targets organisms across a range of generation and turnover times, and a hierarchy of measurable biological states. Measurements encompass species...

Notes on necrophagous flies (Diptera: Calyptratae) associated to fish carrion in Colombian Amazon Acta Amazonica
Amat,Eduardo.
In recent years, there has been an increasing number of studies on carrion fly communities due to their medical importance and as a consequence of the large number of studies on forensic entomology. Surprisingly few studies have adressed with the asynantropic flies of the Amazon, and none were done in Colombia. A faunistic study of asynantropic flies of the families Calliphoridae, Sarcophagidae, Muscidae and Fannidae in three different landscapes of the Colombian Amazon is presented, trapping effectiveness is assessed, and the first record of Mesembrinella batesi (Aldrich, 1922) and Fannia femoralis (Stein, 1897) from Colombia is reported.

Abundance of two Dendrocincla woodcreepers (aves: Dendrocolaptidae) in relation to forest structure in Central Amazonia Acta Amazonica
Cintra,Renato; Maruoka,Adrianny Erika; Naka,Luciano Nicolas.
Few studies have been conducted to verify how the structure of the forest affects the occurence and abundance of neotropical birds. Our research was undertaken between January 2002 and July 2004 at the Reserva Ducke, near Manaus (02º55',03º01'S; 59º53',59º59'W) in central Amazonia, to verify how the forest structure affects the occurrence and abundance of two bird species: the Plain-brown Woodcreeper Dendrocincla fuliginosa and the White-chinned Woodcreeper Dendrocincla merula. Bird species occurrence was recorded using lines of 20 mist-nets (one sample unit), along 51 1-km transects distributed along 9 pararel 8 km trails covering an area of 6400 ha. Along these transects, we placed 50 x 50m plots where we recorded forest structure components (tree...

Trap efficiency evaluation for small mammals in the southern Amazon Acta Amazonica
SANTOS-FILHO,Manoel dos; LÁZARI,Patrick Ricardo DE; SOUSA,Cícero Pedro Farias de; CANALE,Gustavo Rodrigues.
The effectiveness of ecological researches on small mammals strongly depends on trapping techniques to survey communities and populations accurately. The main goal of this study was to assess the efficiency of three types of traps (Sherman, Tomahawk and Pitfall) to capture non-volant small mammals. We installed traps in 22 forest fragments in the southern Brazilian Amazonia. We captured 873 individuals belonging to 21 species; most of the individuals (N = 369) and species (N = 19) were trapped using Pitfalls, followed by Shermans (N = 271 individuals; N = 15 species) and Tomahawks (N = 233 individuals; N = 15 species). Pitfalls trapped a richer community subset of small mammals than the two other types of traps, and a more abundant community subset than...

Effect of water stress on seedling growth in two species with different abundances: the importance of Stress Resistance Syndrome in seasonally dry tropical forest Acta Botanica
Ferreira,Wanessa Nepomuceno; Lacerda,Claudivan Feitosa de; Costa,Rafael Carvalho da; Medeiros Filho,Sebastião.
ABSTRACTIn seasonally dry tropical forests, species carrying attributes of Stress Resistance Syndrome (SRS) may have ecological advantages over species demanding high quantities of resources. In such forests, Poincianella bracteosa is abundant, while Libidibia ferrea has low abundance; therefore, we hypothesized that P. bracteosa has characteristics of low-resource species, while L. ferrea has characteristics of high-resource species. To test this hypothesis, we assessed morphological and physiological traits of seedlings of these species under different water regimes (100%, 70%, 40%, and 10% field capacity) over 85 days. For most of the studied variables we observed significant decreases with increasing water stress, and these reductions were greater in...

Studies in South-Occidental Amazon: contribution to the knowledge of Brazilian Chironomidae (Insecta: Diptera) - doi: 10.4025/actascibiolsci.v34i2.9195 Biological Sciences
Vieira, Lisandro Juno Soares; Universidade Federal do Acre; Rosin, Gisele Cristina; Universidade Estadual de Maringá; Takeda, Alice Michyio; Universidade Estadual de Maringá; Lopes, Maria Rosélia Marques; Universidade Federal do Acre; Sousa, Daniel Silva de; Universidade Federal do Acre.
Chironomidae (Diptera) are a diverse and large group of small flies, whose larvae inhabit nearly every possible niche in most freshwater aquatic ecosystems. The Acre river is an important affluent of the Purus river. Our objective was to contribute to the knowledge of Chironomidae in this region by making the first survey of Chironomidae composition in the Acre river (Amazon Basin), and relate its distribution to physical and chemical variables. Samples were collected at three sites using a modified Petersen grab. A grain size analysis showed heterogeneity between sampling sites. Eighteen morphospecies of Chironomidae larvae were recorded. In site 2, there was higher density of Chironomidae. Higher richness was observed in site 1, and the composition of...

Influence of pitfall designs and use of baits on the capture of small mammals in Southern Minas Gerais, Brazil - doi: 10.4025/actascibiolsci.v35i4.17498 Biological Sciences
Rocha, Daniel Gomes da; Instituto de Desenvolvimento Sustentável Mamirauá / Instituto Nacional de Pesquisas da Amazônia; Passamani, Marcelo; Universidade Federal de Lavras.
Each kind of trap tends to be selective on species sampled, in a way that each one only reveals part of the abundance and species richness of the community sampled. In this way, in order to know the factors that affect the success of sampling methods is crucial for a better planning of experiments and data analysis. The aim of this study was to evaluate the factors that affect the success of pitfall traps in capturing small mammals, such as trap size, designs and use of bait. The study was carried out in two reserves inside the campus of the Universidade Federal de Lavras (UFLA), in South Minas Gerais State, Brazil. In total, 65 specimens belonging to 8 species were caught. Different types of trap design (Y-shaped and I-shaped) have not influenced the...

Asilidae (Diptera) of two Atlantic Forest protected areas of Rio de Janeiro, Southeastern Brazil Anais da ABC (AABC)
MOREIRA-JUNIOR,DANILO P.; MAIA,VALÉRIA C..
ABSTRACT As few Asilidae inventories of Rio de Janeiro areas have been published, there are many data gaps. This paper aims to contribute to the knowledge of richness, abundance and distribution of this family in this State. From January 2013 to March 2014, insects were collected monthly using Malaise traps and every two months using entomological nets in the Reserva Biológica União (REBIO), and Estação Ecológica Estadual de Guaxindiba (EEEG). 682 specimens of Asilidae were collected in the present study, distributed in 31 genera and 51 species (20 identified and 31 unidentified), 527 of REBIO (in 19 genera and 38 species - 14 identified and 24 unidentified), and 155 specimens of EEEG (in 12 genera and 19 species - 6 identified and 13 unidentified)....

Diel variation in abundance and size of the seabob shrimp Xiphopenaeus kroyeri (Crustacea, Penaeoidea) in the Ubatuba region, Southeastern Brazil Anais da ABC (AABC)
Simões,Sabrina M.; Costa,Rogerio C.; Fransozo,Adilson; Castilho,Antonio L..
The objective of the present study was to analyze diel variation in the abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, state of São Paulo, during the year 2000. In each season of the year, collections were made in the day and at night on 9 transects at depths ranging from 2 to 40 m. The estimated shrimp amount was of 28,878 individuals. Although the catch rate was higher during the day (15,853 shrimp), this did not differ significantly from the catch at night (13,025). The catch rate was higher in daytime on most transects, but was higher at night at locations where fine and very fine sand predominated. The majority of juveniles were caught during the day. The mean size (CL) was 14.43 ± 4.02 mm for day and 14.82 ± 4.28...

Variations in the abundance of three Parulidae species in the southern portion of the Brazilian Atlantic Forest, state of Paraná Anais da ABC (AABC)
Santana,Cássius R.; Bochio,Gabriela M.; Anjos,Luiz dos.
We evaluated the distribution of abundance of three species of warblers in the southern portion of the Brazilian Atlantic Forest (BAF): Tropical Parula (Parula pitiayumi), the Golden-Crowned Warbler (Basileuterus culicivorus) and the White-Rimmed Warbler (Basileuterus leucoblepharus). Three types of forests comprise this region of the Atlantic Forest: seasonal semi-deciduous forest (SF), mixed rain forest (MF) and dense rain forest (DF). These forest types occur at different elevations: SF ranging from 200 to 800 m, MF ranging from 800 to 1,200 m and DF ranging from sea level up to 2,000 m. We used point counts in fifteen study areas distributed in the three forest types. The White-Rimmed Warbler and the Tropical Parula had higher abundances in MF, and...

Large-Scale Spatial and Temporal Variability of Larval Fish Assemblages in the Tropical Atlantic Ocean Anais da ABC (AABC)
SOUZA,CHRISTIANE S. DE; MAFALDA JUNIOR,PAULO O..
Abstract This study investigated the large-scale spatial and temporal variability of larval fish assemblages in the west tropical Atlantic Ocean. The sampling was performed during four expeditions. Identification resulted in 100 taxa (64 families, 19 orders and 17 suborders). During the four periods, 80% of the total larvae taken represented eight characteristics families (Scombridae, Carangidae, Paralepididae, Bothidae, Gonostomatidae, Scaridae, Gobiidae and Myctophidae). Fish larvae showed a rather heterogeneous distribution with density at each station ranging from 0.5 to 2000 larvae per 100m3. A general trend was observed, lower densities at oceanic area and higher densities in the seamounts and islands. A gradient in temperature, salinity,...
