1. AUTOMATED INDIVIDUAL TREE DETECTION IN AMAZON TROPICAL FOREST FROM AIRBORNE LASER SCANNING DATA
ABSTRACT Light Detection and Ranging (LiDAR) derived individual tree crown attributes can potentially serve as a tool for ecology and forest dynamics studies and reduce field inventory costs. In this study, four methods of individual tree detection (ITD), Watershed, Silva et al. (2016), Dalponte and Coomes (2016), and Coomes et al. (2017), were evaluated in

2. Efectos del fuego en el arbolado de un bosque tropical de pino y en el de una selva baja caducifolia en Villaflores, Chiapas
Abstract It is expected an increase of forest fires world-wide because of global warming. So is important the study of fire ecology and fire effects in different ecosystems. In Villaflores, Chiapas, Mexico, are conducted efforts towards the integral fire management. There was studied a Pinus oocarpa Schiede forest, as well as a tropical dry forest, affected

3. Habitat use, fruit consumption, and population density of the black-headed night monkey, Aotus nigriceps, in southeastern Peru
ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group com

4. Arbuscular mycorrhizal fungal communities in soils under three phytophysiognomies of the Brazilian Atlantic Forest
ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophy

5. Nesting biology of three Megachile (Hymenoptera: Megachilidae) species from Eastern Amazonia, Brazil
Abstract Megachile Latreille is a conspicuous genus of solitary bees distributed worldwide. However, the biology of tropical species is still little known. We present data on biology of Megachile brasiliensis Data Torre, Megachile sejuncta Cockerell and Megachile stilbonotaspis Moure found in two remnants of eastern Amazonian forest in northeastern Brazil.

6. Relating flight initiation distance in birds to tropical dry forest restoration
ABSTRACT Flight initiation distance (FID), defined as the distance at which an individual flees from an approaching predator, might depend on how the individual perceives the risk of being predated. Using a standardized walking approach method on focal bird individuals, we investigated whether different levels of vegetation cover (habitat) influence the perc

7. Dung beetle assemblages (Coleoptera, Scarabaeinae) in Atlantic forest fragments in southern Brazil
Dung beetle assemblages (Coleoptera, Scarabaeinae) in Atlantic forest fragments in southern Brazil. The beetles of the subfamily Scarabaeinae are important organisms that participate in the cycle of decomposition, especially in tropical ecosystems. Most species feed on feces (dung) or carcasses (carrion) and are associated with animals that produce their foo

8. Ecologia de Chiroptera, em áreas de caatinga, com considerações zoológicas e zoogeográficas sobre a fauna de morcegos dos Estados da Paraíba e Ceará. / Ecology of Chiroptera in Caatinga areas, with considerate zoologiques and zoogeographic about the bat fauny of the states Paraíba and Ceará.
No bioma Caatinga, apesar deste ser o único exclusivamente brasileiro e uma das 37 grandes regiões naturais do mundo ao lado da Amazônia e do Cerrado, bem como apresentar apenas 52,6% de sua cobertura vegetal original devido ao acelerado ritmo de descaracterização e deserficação que acomete a região, a deficiência no conhecimento da diversidade, tax

9. Mecanismos de coexistência em florestas tropicais : variações ontogenéticas de arquitetura aérea, padrão espacial e performance de espécies congenéricas simpátricas em uma floresta tropical úmida de terras baixas / Coexistence mechanisms in tropical forests : ontogenetic variation in aboveground architecture, spatial patterns and performance of sympatric congeneric species in a lowland tropical rain forest
A alta diversidade em florestas tropicais tem motivado questionamentos sobre a importância da diferenciação de nicho como mecanismo de coexistência. Nessa hipótese, a heterogeneidade ambiental proporcionaria eixos de diferenciação que facilitariam a coexistência, sendo, portanto, esperadas diferenças entre espécies na associação a gradientes espa

10. Distribuição espacial e sazonalidade na borboleta Heliconius sara apseudes (Nymphalidae: Heliconiini) em uma floresta subtropical, no litoral do sudeste brasileiro / Spatial and seasonal distribution in the butterfly Heliconius sara apseudes (Nymphalidae: Heliconiini) in a subtropical forest in southeastern Brazilian coast
A ecologia de populações busca entender a variação na abundância das espécies no tempo e no espaço. Espécies que possuem ciclos de vida de curta duração, como a maior parte dos insetos, se tornam especialmente convenientes para essa finalidade. Este estudo examinou os padrões de abundância durante o ano 2009 de uma borboleta tropical próximo ao

11. Drought resistance in seedlings tree species of semideciduous tropical forest / Resistência à seca em plântulas de espécies arbóreas da floresta estacional semidecídua
The rainfall is high in tropical forests, but there is great variation in water availability to plants. On a local scale, this availability may vary depending on the location of individuals in gaps, their position in the landscape and soil composition. On a regional scale, variations related to the volume and distribution of rainfall, coupled with seasonal c

12. Population ecology of small rodents and marsupials in a semi-deciduous tropical forest of the southeast Pantanal, Brazil
The Pantanal is a South American biome characterized by extensive plains and stark environmental seasonality. Several habitats are subject to annual flooding, forcing small mammal species to aggregate in dry forest patches, which most likely influences their population dynamics and life history strategies. In order to investigate the seasonal influence on th
