AbstractAlbinism is the absence of pigmentation or coloration and is rarely found in nature. In this study we examined photos and videos obtained by cameras traps in the Legado das Águas Reserve. In the images, we identified two albino lowland tapirs. The results highlight the necessity of understanding the genetic diversity of lowland tapir populations and the important role of the professional photography associated with scientific research.

Due to the few studies in ornithology in the gleba menor of the Sassafras and Canela Preta Biological, the objective of this study was to evaluate the role of these Units for the preservation of forest birds. In the field, a monthly quantitative inventory was carried out, covering all seasons and periods of the day. The specimens were identified by sonic and visual evidences using a 7 X 35 mm binocular. The displacement in each area was one hour, carried out by walking at a constant speed (± 3.0 km / h) on pre-existing tracks, covering the largest area and possible environments. For each unit with the area and perimeter values, the form factor was calculated. With a sample effort of 65 and 71 hours of observation for the Canela Preta Biological Reserve and for the gleba menor, it was possible to record 182 and 190 species respectively. The richness in the areas can be considered high when compared to the richness in the greater area in the Sassafras Rebio (3,840 ha), where 237 species were registered. Among the species are those considered endemic, which for the two areas add up to 84 species, such as Lipaugus lanioides (Lesson, 1844). It was possible to record the presence of species characteristic of altitudes such as: Pyrrhocoma ruficeps (Strickland, 1844). Among species of conservation interest we have Amazona vinacea (Kuhl, 1820) considered threatened (EN). The most representative species was the Critically Endangered (CR) Primolius maracana (Vieillot, 1816). For the shape factor we obtained values of 0.21 (Sassafras) and 0.18 (Canela-Preta). Values less than 1 indicate a more circular area and, consequently, less edge effect. From the above, it is evident the importance of these protected areas  for the conservation of bird species against the fragmentation of the Atlantic Forest in Santa Catarina.

Abstract:Ant–treehopper mutualisms are centred on the availability of honeydew, a sugary fluid offered by treehoppers to attract ants, which respond by defending their hosts against predators and parasitoids. However, due to differences in the treehopper social behaviour (i.e. the amount of food resource available) ants can monopolize treehopper aggregations in many ways. Here we evaluated the topological structure of quantitative ant–treehopper interaction networks in three Brazilian Atlantic Forest localities. Moreover, we specifically investigated the role of ant recruitment strategy and treehopper behaviour in the structure of these networks. For this, we sampled ant–treehopper interactions along representative transects (6 km per site) within each studied site and recorded the mean number of individuals of treehopper and ant species. We found that independent of variation in environmental factors among study sites, ant–treehopper networks were highly compartmentalized (Mean ± SD: Q = 0.34 ± 0.1) when compared with null models, and exhibit low connectance (C = 0.18 ± 0.01) and specialization (H2’ = 0.36 ± 0.08) values. In addition, we also observed that larger aggregations of treehoppers interacted with a higher number of ant species and ants that were locally dominant and showed massive recruitment interacted with a larger number of treehopper species. In summary, our results illustrate the importance of foraging strategies in shaping ecological interactions in tropical environments.

Wet And Dry Seasons

Trogons are pan-tropical forest birds that eat a mix of fruits and arthropods. With direct observations of wild feeding birds, I assessed the relative contribution of fruits and arthropods to the diet of three trogon species (Trogonviridis, T.surrucura, and T.rufus) at Parque Estadual Intervales, southeast Brazil. Fruits and arthropods made the bulk of the food items recorded, with a tendency of frugivory increasing with body mass. The Trogon species differed in the proportion of fruits and arthropods taken, with T.viridis being the most frugivorous species (66% of feeding bouts, n = 47). The relative contribution of fruits and arthropods did not differ between the wet and dry seasons for any species. In the omnivorous gradient, T.viridis is close to the frugivorous extreme, whereas T.surrucura and T.rufus is next to the insectivorous end. Such a distinction may have important consequences for the territoriality and social behavior of these birds.
