Time-Lag in Responses of Birds to Atlantic Forest Fragmentation: Restoration Opportunity and Urgency.

Alexandre Uezu; Jean Paul Metzger

PLoS ONE, Vol. 11 No. 1 · 2016 · English · DOAJ Scopus

There are few opportunities to evaluate the relative importance of landscape structure and dynamics upon biodiversity, especially in highly fragmented tropical landscapes. Conservation strategies and species risk evaluations often rely exclusively on current aspects of landscape structure, although…

Patterns of Vertebrate Diversity and Protection in Brazil

Clinton N. Jenkins; Maria Alice S. Alves; Alexandre Uezu et al.

PLOS ONE, Vol. 10 No. 12 · 2015 · English · PLOS Scopus

Most conservation decisions take place at national or finer spatial scales. Providing useful information at such decision-making scales is essential for guiding the practice of conservation. Brazil is one of the world’s megadiverse countries, and consequently decisions about conservation in the…

Selection of habitat by the jaguar, Panthera onca (Carnivora: Felidae), in the upper Paraná River, Brazil

Laury Cullen Junior; Dênis A. Sana; Fernando Lima et al.

Zoologia (Curitiba), Vol. 30 No. 4 · 2013 · English · DOAJ Scopus

We used data from VHF and GPS radio-tagged jaguars, Panthera onca (Linnaeus, 1758) to quantify jaguar habitat selection and how adult individuals in the Upper Paraná River region selected among the available habitat types. We followed the framework in which animals make decisions about resource use…

Implications of Fine-Grained Habitat Fragmentation and Road Mortality for Jaguar Conservation in the Atlantic Forest, Brazil

Laury Cullen Jr.; Jessica C. Stanton; Fernando Lima et al.

PLOS ONE, Vol. 11 No. 12 · 2016 · English · PLOS Scopus

Jaguar (Panthera onca) populations in the Upper Paraná River, in the Brazilian Atlantic Forest region, live in a landscape that includes highly fragmented areas as well as relatively intact ones. We developed a model of jaguar habitat suitability in this region, and based on this habitat model, we…

Use of small Atlantic Forest fragments by birds in Southeast Brazil

Karlla Vanessa de Camargo Barbosa; Christoph Knogge; Pedro Ferreira Develey et al.

Perspectives in Ecology and Conservation, Vol. 15 No. 1 · 2017 · English · DOAJ Scopus

Small forest fragments may play a major role in fragmented areas, but there is scarce empirical data to test this hypothesis. To understand in which context birds can use small Atlantic Forest fragments, we tested the presence of 11 bird species in 30 small fragments (4–10 ha), in a range of…

Landscape heterogeneity buffers soundscape degradation in human-modified landscapes

Júlio Cesar Lima de Araújo; Vinicius de Avelar São Pedro; Alexandre Uezu et al.

Perspectives in Ecology and Conservation, Vol. 24 No. 3 · 2026 · English · DOAJ Scopus

Land-use intensification reshapes tropical landscapes, altering the spatial structure of habitats and affecting acoustically active biodiversity. We assessed how habitat amount and landscape heterogeneity jointly influence soundscapes in 72 Atlantic Forest landscapes spanning 5–85% native…

Populations across bird species distribution ranges respond differently to habitat loss and fragmentation: implications for conservation strategies

Érica Hasui; Alexandre Camargo Martensen; Alexandre Uezu et al.

Perspectives in Ecology and Conservation, Vol. 22 No. 1 · 2024 · English · DOAJ Scopus

Conservation strategies often assume uniform response to habitat loss and fragmentation among species. We investigated whether bird species' responses to habitat changes vary based on their distribution range and local environmental suitability. Additionally, we explored associations between…

How Far Can Nature-Based Solutions Increase Water Supply Resilience to Climate Change in One of the Most Important Brazilian Watersheds?

Letícia Duarte de Freitas; Jener Fernando Leite de Moraes; Adriana Monteiro da Costa et al.

Earth, Vol. 3 No. 3 · 2022 · English · DOAJ Scopus

Water resources are paramount for the maintenance of the Earth’s system equilibrium; however, they face various threats and need increased conservation and better management. To restore water resources, nature-based solutions can be applied. Nevertheless, it is unclear which solution promotes…

Deforestation alters species interactions

Benjamin Howes; Manuela González‐Suárez; Henrik Jeldtoft Jensen et al.

Natural Sciences, Vol. 3 No. 2 · 2023 · English · DOAJ Scopus

Abstract Interspecific interactions are a major determinant of stability in ecological communities and are known to vary with biotic and abiotic conditions. Deforestation is the primary driver of the ongoing sixth mass extinction, yet its effect on species interactions remains largely unexplored…

Ecological monitoring using Collembola metabarcoding with extremely low bycatch amplification

Pedro M. Pedro; Laury Cullen Jr.; Fabiana Prado et al.

Ecological Indicators, Vol. 157 · 2023 · English · DOAJ Scopus

Collembola are used widely to monitor soil health and functional parameters. Recent developments in high throughput sequencing (especially metabarcoding) have substantially increased their potential for these ends. Collembola are especially amenable to metabarcoding because of their small size…
