Bats use live fences to move between tropical dry forest remnants
<p>Linear features can benefit wildlife by assisting animal movement. We captured bats along barbed-wire and live-tree fences connecting Tropical Dry Forest patches in Nicaragua. Bat species richness and captures were higher along live fences but we noted differences in sex ratios, richness, and species composition compared to surrounding natural forests.</p>
Data from: Seed-dispersal networks in tropical forest fragments: area effects, remnant species, and interaction diversity
<p>Seed dispersal interactions involve key ecological processes in tropical forests that help to maintain ecosystem functioning. Yet this functionality may be threatened by increasing habitat loss, defaunation and fragmentation. However, generalist species, and their interactions, can benefit from the habitat change caused by human disturbance while more specialized interactions mostly disappear. Therefore changes in the structure of the local, within fragment, networks can be expected. Here we investigated how the structure of seed-dispersal networks changes along a gradient of increasing habitat fragmentation. We analysed 16 bird seed-dispersal assemblages from forest fragments of a biodiversity-rich ecosystem. We found significant species-, interaction- and network-area relationships, yet the later was determined by the number of species remaining in each community. The number of frugivorous bird and plant species, their interactions, and the number of links per species decreases as area is lost in the fragmented landscape. In contrast, network nestedness has a negative relationship with fragment area, suggesting an increasing generalization of the network structure in the gradient of fragmentation. Network specialization was not significantly affected by area, indicating that some network properties may be invariant to disturbance. Still, the local extinction of partner species, paralleled by a loss of interactions and specialist-specialist bird-plant seed dispersal associations suggests the functional homogenization of the system as area is lost. Our study provides empirical evidence for network-area relationships driven by the presence/absence of remnant species and the interactions they perform.</p>
Vertical distribution of epiphytic lichens on Quercus laurina Humb. & Bonpl. in a remnant of cloud forest in the state of Veracruz, México
<p>It is considered that in the tropics, lichen richness and cover tend to increase from the trunk base to the top of the crown of trees. In this study we calculate total beta diversity of the lichen community along a vertical gradient on Quercus laurina. By comparing the richness and cover of the lichens by zone, we will be able to prove that the foliose and fruticose forms will be the minor component of the total lichen species richness; but with the highest cover with respect to the crustose lichens. Five zones were identified in each phorophyte (n=15) with a diameter at breast height > 40 cm. A total of 92 species were identified, of these, 38% were found only in a single zone, 51% were shared between the different zones, 11% occurred across all zones. Species richness and cover increased from the lowest to the highest zones of phorophytes. Dissimilarity in species composition between the zones, can be explained by species replacement. The Indicator Species Analysis revealed that only a few species such as Hypotrachyna vexans, H. cf. sublaevigata and Ramalina cf. sinaloensis preferred a particular zone. The results obtained to date show that the lichen community associated with Quercus laurina phorophytes is highly diverse. There is a high replacement of species across the different zones. Our results suggest that species richness and cover of the corticolous lichen community are related to the zone and the diverse growth forms.</p>

Relationship of woody species composition with edaphic characteristics in threatened riparian Atlantic Forest remnants in the upper Rio Doce basin, Brazil
<p class="MsoNormal"><span>Studies on the composition, richness, and diversity of plant species in <span>tropical</span> communities are essential for understanding relevant ecological processes and for developing appropriate conservation policies. </span><span>Considering that areas subject to direct impacts due to dam breach may in the long-term present changes in species composition and in soil parameters, we evaluated the composition of the flora, described the current vegetation profile, and evaluated whether differences in species composition was influenced by soil variables of three areas along the Gualaxo River, in Minas Gerais State, Brazil. In addition, we identified important plant species through occurrence and phytosociological parameters for ecological restoration projects in the affected region, serving as reference areas. We sampled plant species with DBH ≥ 5 cm (diameter at breast height – measured 1.30 m above ground level) in 77 plots distributed in three riparian forest areas. We calculated phytosociological parameters and related them to edaphic factors. </span><span>A total of 1579 individual plants belonging to 53 botanical families and 227 species were sampled in the three areas. The Fabaceae family was the most representative with 46 species. </span><span>Species composition and diversity among the sampled areas was similar and was associated with edaphic factors. Furthermore, some species (e.g. <em>Xylopia sericea</em>, <em>Cupania emarginata</em> and <em>Ocotea pulchalla</em>) showed an important relation with soil variables. Some species of the genera (e.g., <em>Byrsonima</em>, <em>Xylopia</em>, <em>Ocotea</em>, and <em>Croton</em>) and families (e.g., Fabaceae and Myrtaceae) found here, can be important species in the restauration process for the local and regional maintenance of floristic identity in the Rio Doce river.</span></p>
