“…Shorter distances imply higher chances for connectivity to occur, while longer ones represent lower chances. Considering that gap-crossing capabilities beyond 100 m are very unlike for the regional birds, we chose 60 m as a limit to test functional connectivity, ensuring higher relevance of results Boscolo, Candia-Gallardo, Awade, & Metzger, 2008). Besides that, we also analyzed the structural connectivity, expressed by 0 m of distance between forest patches (gap-crossing capability of 0 m), which represented the strictly forest species.…”

Restoration projects designed to promote one ecosystem service may have synergistic benefits to other services. Therefore, bundling them can be an effective way to maximize the return to the investments in programs of payments for ecosystem services (PES). Here, we investigated the additional gain of restoration actions-which were implemented as part of a PES program to protect a key watershed for water supply-on increasing functional landscape connectivity in the Atlantic Forest region of southeastern Brazil. Using a landscape ecology approach, we estimated the amount of forest cover before (2006) and after (2012) restoration activities by the PES program and changes in structural and functional landscape connectivity for birds with varying gap-crossing capabilities. Forest cover increased from 42.5 to 86.1 ha after the implementation of restoration projects by the PES program. In the simulated scenarios of landscape connectivity, the mean patch size of functionally connected forest increased by 1,034%, 392%, 248%, and 94% for species with gap-crossing capabilities of 0, 20, 40, and 60 m, respectively. Our results highlight the potential for incorporating biodiversity conservation objectives into PES projects primarily designed to enhance water-related ecosystem services.

“…The Chestnut-capped Brush-finch used stepping-stones to reduce flying distance from 130 m in a single flight to an average of 54 m paths. Similar behavior has been recorded for Lesser Woodcreeper (Xiphorhynchus fuscus), a resident insectivorous bird in the Brazilian Atlantic forest [26]. Once in the corridor, the Chestnut-capped Brush-finch did not have any difficulty moving through forest habitat and returning to its source location, as seen in other tropical lowland species [14].…”

“…The individual translocated 144 m (gap distance of 119 m) took three days to return to its source location, whereas the other Streak-capped Treehunter individual, translocated 250 m (gap distance of 172 m), did not return during the tracking period. These results suggest potential reluctance to cross wide inter-habitat gaps, as have been documented in other species in tropical lowland and boreal forests [14,26,27]. Presumably the absence of cover and perches in a pasture matrix may hinder, or at least delay, understory birds' decision to traverse openhabitat matrix [28,29].…”

We documented movement of a long-distant migrant (Swainson's Thrush Catharus ustulatus) and two understory resident species (Chestnut-capped Brush-finch Buarremon brunneinuchus and Streak-capped Treehunter Thripadectes virgaticeps) in a fragmented landscape dominated by a pasture matrix in a SubAndean region of central Colombia. Swainson's Thrush had no detectable difficulties traversing a pasture matrix and returning to the capture site. Chestnut-capped Brush-finch and Streak-capped Treehunter (understory resident species) avoided making lengthy flights and used stepping-stones and nearby corridors to ease their movement. Providing stepping stones such as live fences and isolated trees and maintaining corridors can enhance functional connectivity in regions with fragmented forests, aiding the conservation of bird species.Key words: Colombia, forest fragmentation, landscape matrix, land-use change, radio-telemetry Resumen Documentamos el movimiento de un migrante de larga distancia (Catharus ustulatus) y dos especies residentes de sotobosque (Buarremon brunneinuchus y Thripadectes virgaticeps) en un paisaje fragmentado dominado por una matriz de pastos en la región subandina del centro de Colombia. Catharus ustulatus no tuvo ninguna dificultad detectable en atravesar la matriz de pastos y regresó al sitio de captura. Por otro lado, B. brunneinuchus y T. virgaticeps (las especies residentes de sotobosque) evitaron hacer vuelos prolongados y utilizaron árboles aislados y corredores cercanos para facilitar su movimiento. Implementación de pasaderas como cercas vivas y árboles aislados, y el mantenimiento de corredores puede contribuir a la conservación de aves mediante la mejora de la conectividad funcional en regiones con bosques fragmentados.Palabras clave: Colombia, fragmentación de bosque, matriz del paisaje, uso de suelo, radio-telemetría Mongabay

“…Entretanto, o registro de um número maior de espécies de pica-paus talvez seja reflexo do grau de dependência de ambientes florestais, que foi menor quando comparado com o dos arapaçus (Tabela 1). Se considerarmos que pelo menos X. fuscus tenha habilidade limitada de se movimentar entre fragmentos (Boscolo et al 2008), tornam-se fundamentais iniciativas de pesquisa que visem estudar os efeitos do isolamento Biota Neotrop.,vol. 11,no.…”

A Zona da Mata Mineira está localizada no sudeste do estado de Minas Gerais, nos domínios da Mata Atlântica, e é uma região altamente fragmentada, com muitas manchas pequenas e isoladas, cuja avifauna é pouco estudada. O objetivo deste trabalho foi inventariar a avifauna da Reserva Biológica Municipal Poço D'Anta (277 ha), uma área de floresta do município de Juiz de Fora, sudeste de Minas Gerais, através da caracterização de alguns aspectos ecológicos e o status de conservação. O levantamento foi realizado entre os períodos de março a setembro de 2007, e março de 2008 a maio de 2009, utilizando a lista de Mackinnon, capturas com redes-de-neblina e observações ocasionais. Foram identificadas 156 espécies, das quais 44 (28%) são endêmicas da Mata Atlântica e seis (3,8%) estão sob algum grau de ameaça. Dentre as espécies ameaçadas, cinco são dependentes de floresta (Dysithamnus stictothorax, Drymophila ochropyga, Sporophila frontalis, Sporophila falcirostris, Cyanoloxia moesta). Em geral a comunidade é caracterizada por aves com sensibilidade média ou baixa a perturbações ambientais. Contudo foram identificadas oito (5,1%) espécies com elevada sensibilidade (Pulsatrix koeniswaldiana, Conopophaga melanops, Sclerurus scansor, Xiphorhynchus fuscus, Lepidocolaptes squamatus, Campylorhamphus falcularius, Anabazenops fuscus e Habia rubica). Além disso, algumas espécies já consideradas extintas em vários outros fragmentos do sudeste do estado estiveram presentes na área. Houve predomínio de espécies insetívoras (39,4%; n = 61) e onívoras (31,6%; n = 49). Como área legalmente protegida e pela sua extensão, considerando as características regionais, a Reserva Biológica Municipal Poço D'Anta tem um papel importante em abrigar populações de aves que vem enfrentando persistentes efeitos antropogênicos na região. A avifauna local está sujeita a impactos tais como atropelamentos, invasões de espécies exóticas e a caça, embora já existam propostas de medidas mitigadoras no plano de manejo da área. Ressalta-se o caráter de urgência em relação à implantação destas medidas a fim de minimizar os impactos sofridos pela avifauna.
