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 · Inggris · 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…

Revista Ambiente & Água, Vol. 8 No. 3 · 2013 · Portugis · DOAJ Scopus

The National Water Resources Policy established the principles of participation, integration and decentralization, as well as new instruments for the management of water resources in Brazil. The implementation of this policy created several challenges, such as establishing effective management…

A governança nexo água, energia e alimentos e os espaços públicos de participação social: um estudo aplicado ao contexto do Sistema Produtor de Água Cantareira

Rafael Eduardo Chiodi; Samuel Mello Pinto; Alexandre Uezu

Desenvolvimento e Meio Ambiente, Vol. 58 No. 0 · 2021 · Portugis · DOAJ Scopus

A abordagem nexo água, energia e alimentos reconhece as interconexões entre os sistemas hídrico, energético e alimentar, e, para que a gestão integrada destes seja eficiente e sustentável, propõe que ocorra dentro de processos de governança. No Brasil, os espaços de participação para a gestão de…

Patterns of Vertebrate Diversity and Protection in Brazil

Clinton N. Jenkins; Maria Alice S. Alves; Alexandre Uezu dkk.

PLOS ONE, Vol. 10 No. 12 · 2015 · Inggris · 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…

A EFICÁCIA DA APLICAÇÃO DA LEI DE CRIMES AMBIENTAIS PARA A PROTEÇÃO DO MEIO AMBIENTE NO LITORAL SUL DA BAHIA

Reinaldo Martins Lemos; Alexandre Uezu; Maria José Brito Zakia dkk.

Revista Eletrônica do Curso de Direito da UFSM, Vol. 8 No. 2 · 2013 · Portugis · DOAJ

Este trabalho buscou avaliar a efetividade da aplicação da Lei de Crimes Ambientais e o andamento dos processos administrativos e judiciais no Litoral Sul da Bahia, como forma de proteção ambiental. Esta região é de grande importância ecológica, onde possui várias Unidades de Conservação, por isso…

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

Laury Cullen Junior; Dênis A. Sana; Fernando Lima dkk.

Zoologia (Curitiba), Vol. 30 No. 4 · 2013 · Inggris · 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 dkk.

PLOS ONE, Vol. 11 No. 12 · 2016 · Inggris · 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 dkk.

Perspectives in Ecology and Conservation, Vol. 15 No. 1 · 2017 · Inggris · 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 dkk.

Perspectives in Ecology and Conservation, Vol. 24 No. 3 · 2026 · Inggris · 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…

Influência do entorno de uma unidade de conservação sobre a pressão de caça: RPPN Estação Veracel como estudo de caso

Gildevânio Pinheiro dos Santos; Miriam Lucia Lages Perilli; Laury Cullen Jr. dkk.

Biodiversidade Brasileira, Vol. 8 No. 2 · 2018 · Portugis · DOAJ

A caça de animais silvestres é uma das atividades humanas mais antigas e, associada a aplicação de técnicas de caça modernas, pode levar rapidamente a uma superexploração e até a extinção de espécies. A caça no Brasil é ilegal na maior parte dos casos, mas ainda é uma atividade comum. Por ser uma…

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

Érica Hasui; Alexandre Camargo Martensen; Alexandre Uezu dkk.

Perspectives in Ecology and Conservation, Vol. 22 No. 1 · 2024 · Inggris · 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 dkk.

Earth, Vol. 3 No. 3 · 2022 · Inggris · 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
