1. Frugivoria por aves em quatro espécies de Cactaceae na Caatinga, uma floresta seca no Brasil
RESUMO As aves são conhecidas por desempenharem um importante papel na reprodução de diversas espécies de plantas através da frugivoria e dispersão de sementes. Apesar da importância das cactáceas em ambientes sazonais, poucos estudos avaliaram interações entre essas plantas e aves frugívoras. O presente trabalho identificou as espécies de aves q

2. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

3. Breeding system and pollination of Pleroma trichopodum DC. (Melastomataceae): a potential species for the restoration of Atlantic Forest in southern Brazil
ABSTRACT Plant-pollinator interactions and their reproductive implications are of central importance to the organization of plant populations and communities in restoration areas. We studied the breeding system and flower visitors of Pleroma trichopodum, a pioneer species of the Atlantic Forest. We attempted to answer three questions: (1) Is P. trichopodum d

4. 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

5. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

6. Seroprevalence of
Borrelia burgdorferi in occupationally exposed persons in the Belgrade area, SerbiaLyme disease (LD) is a natural focal zoonotic disease caused by
Borrelia burgdorferi, which is mainly transmitted through infectedIxodes ricinus tick bites. The presence and abundance of ticks in various habitats, the infectivity rate, as well as prolonged human exposure to ticks are factors that may affect the infectionBraz. J. Microbiol..

7. The existence of only one haplotype of Leishmania major in the main and potential reservoir hosts of zoonotic cutaneous leishmaniasis using different molecular markers in a focal area in Iran
IntroductionLeishmania major is the causative agent of zoonotic cutaneous leishmaniasis (ZCL), and great gerbils are the main reservoir hosts in Iran. Abarkouh in central Iran is an emerging focal point for which the reservoir hosts of ZCL are unclear. This research project was designed to detect any Leishmania parasites in different wild rodent species.Meth

8. Immediate graft histological assay, post pig's liver transplantation
PURPOSE: To describe the vascular and tissue histopathological changes in seven sequential experimental liver transplantations in pigs. METHODS: Fourteen female pigs, Sus domesticus species, with body mass between 5 and 8 kg were utilized. After the end of all anastomoses of the graft implantation in the receptor, the animal was monitored for 30 minutes, and

9. Reprodução, distribuição e padrões de co-ocorrência em uma comunidade de palmeiras na Amazônia central: Uma abordagem teórica e experimental / Main drivers controlling reproduction, distribution and co-occurrence patterns in a palm community in a terra firme Forest at central Amazonia: A theoretical and experimental approach
One of the main concerns of community ecology is to determine which factors affect species distribution. Starting from the premise that fruit production is the last step of true establishment, we match environmental gradients and the experimental approaches with help from phylogenetic tools to bring light into the mechanisms influencing palm distribution pat

10. Thermal ecology and thermoregulatory behavior of Coleodactylus natalensis (Squamata: Sphaerodactylidae), in a fragment of the Atlantic forest of northeastern, Brazil
We studied the thermal ecology and thermoregulatory behavior of Coleodactylus natalensis Freire, 1999 in a remnant of a northern coastal patch of the Brazilian Atlantic Forest. Data were collected during four 20-day field excursions over the course of one year. We assessed the importance of substrate and air temperatures, in addition to time of exposure to s

11. Mixed-species schooling behavior and protective mimicry involving coral reef fish from the genus Haemulon (Haemulidae)
O presente estudo analisou o comportamento de formação de cardumes mistos e mimetismo de proteção envolvendo espécies do gênero Haemulon e demais peixes recifais nos recifes costeiros de Tamandaré, estado de Pernambuco, Nordeste do Brasil. O trabalho foi realizado utilizando observações subaquáticas e incluiu 35 horas de observação direta utiliza

12. Levantamento de espécies com vocação para facilitar processos de restauração espontânea de ecossistemas perturbados na vertente atlântica da Serra do Mar, Piraí RJ. / Survey of species destined to facilitate spontaneous processes of restoration of disturbed ecosystems in the Atlantic slope of the Serra do Mar, Piraí - RJ.
Ecossistemas perturbados apresentam composição florística alterada, com predomínio de vegetação de porte herbáceo, solos exauridos, rasos, pedregosos, com baixa infiltração e geodinamismos dos processos erosivos distintos. Os indivíduos florestais que colonizam estes ambientes foram considerados espécies rústicas. Eles foram levantados por censo
