Special feature - connectivity in fragmented landscapes
Habitat fragmentation drives inter-population variation in dispersal behavior in a Neotropical rainforest bird
Cintia Cornelius, Marcelo Awade, Carlos Cândia-Gallardo, Kathryn E. Sieving, Jean Paul Metzger
Perspectives in Ecology and Conservation. 2017;15:3-9

  • We tested predictions of a model for non-optimal animal movement in modified landscapes.

  • In fragmented landscapes dispersal success is lower for birds from continuous forests.

  • Fragmented landscape birds are slow-explorers probably obtaining better information about the landscape.

  • Dispersal success is higher for birds from fragmented landscapes.

  • Gradual landscape changes should be favored to avoid non-optimal spatial behaviors.

Matrix type affects movement behavior of a Neotropical understory forest bird
Mariane Biz, Cintia Cornelius, Jean Paul Walter Metzger
Perspectives in Ecology and Conservation. 2017;15:10-7

  • The predation risk was variable among the analyzed matrices (pasture, cornfields and Eucalyptus plantation)

  • Differences between matrices can be perceived by individuals who change their behaviors in order to maximize benefits and minimize risk at each environment.

  • The risk of predation can be reduced when the visual field facilitates the perception of fragments in the environment (pasture) or when the matrix offers resources and shelters (Eucalyptus).

  • Tortuous movements can either mean lack of direction (i.e. visual obstruction, cornfield) or resource utilization or pauses to avoid predators (Eucalyptus).

  • This study shows the importance of planning and managing matrices to reduce risks and favors landscape connectivity, especially around isolated native vegetation areas.

Positive responses of flower visiting bees to landscape heterogeneity depend on functional connectivity levels
Danilo Boscolo, Paola Mandetta Tokumoto, Patrícia Alves Ferreira, John Wesley Ribeiro, Juliana Silveira dos Santos
Perspectives in Ecology and Conservation. 2017;15:18-24

  • Land changes can hinder landscape-level pollination through bee species loss.

  • Bees were more diverse at functionally connected and highly heterogeneous landscapes.

  • We propose non-linear effects of heterogeneity and functional connectivity on bees.

  • Proper landscape-level bee pollination needs interspersed high quality environments.

Investigating movement behavior of invasive Burmese pythons on a shy–bold continuum using individual-based modeling
Holly E. Mutascio, Shannon E. Pittman, Patrick A. Zollner
Perspectives in Ecology and Conservation. 2017;15:25-31

  • Burmese pythons are invasive to the Everglades and are expanding into more fragmented habitats.

  • Movement behavior may impact how the landscape influences python populations in Florida.

  • We used simulation modeling to investigate how behavior impacts population expansion.

  • A behaviorally plastic boldness strategy best matched observed python expansion.

  • Behavioral trade-offs and behavioral flexibility may influence population expansion.

Ecosystems as infrastructure
José Maria Cardoso da Silva, Emily Wheeler
Perspectives in Ecology and Conservation. 2017;15:32-5

  • The concept of ecosystems as infrastructure is reviewed.

  • The terms green, ecological, natural, and blue have been used in the literature.

  • Green infrastructure is the most commonly used name.

  • A more inclusive concept for green infrastructure is proposed.

  • Design principles for green infrastructure at all spatial scales are suggested.

Effects of landscape composition on the occurrence of a widespread invasive bird species in the Brazilian Atlantic Forest
Ivan Réus Viana, Jayme Augusto Prevedello, Jairo José Zocche
Perspectives in Ecology and Conservation. 2017;15:36-41

  • Human activities increase the number of invasive species.

  • Landscape composition is related with invasive alien species occurrence.

  • Landscape composition can be a useful landscape predictor of biological invasion.

  • A landscape perspective may help to mitigate the impacts of invasive species on native biodiversity.

Use of small Atlantic Forest fragments by birds in Southeast Brazil
Karlla Vanessa de Camargo Barbosa, Christoph Knogge, Pedro Ferreira Develey, Clinton N. Jenkins, Alexandre Uezu
Perspectives in Ecology and Conservation. 2017;15:42-6

  • Small patches can increase landscape connectivity depending on the landscape context.

  • The use of small patches by birds can be more influenced by matrix composition.

  • Eucalyptus matrix favored a higher number of species in small patches.

Aversive hunting and sight frequency ecology of Beaded lizards (Squamata: Helodermatidae)
Hublester Domínguez-Vega, Octavio Monroy-Vilchis, Javier Manjarrez, Carlos J. Balderas-Valdívia
Perspectives in Ecology and Conservation. 2017;15:47-51

  • Almost half of Beaded lizards that encounter humans are victims of aversive hunting.

  • Sightings increase in conserved areas whilst hunting may be explained by cultural dogmas.

  • Dissemination of knowledge about Beaded lizards may greatly enhance their conservation.

  • Habitat management and tolerance are essential steps in the conservation strategy.

Effect of shrub encroachment on vegetation communities in Brazilian forest-grassland mosaics
Anaclara Guido, Elisa Salengue, André Dresseno
Perspectives in Ecology and Conservation. 2017;15:52-5

  • There are conservation concerns with shrub expansion due to lack of management.

  • Baccharis uncinella encroachment affects grassland vegetation, reducing total plant richness.

  • This study presents empirical data that contributes to conservation efforts of forest-grassland mosaics.

  • Management practices that maintain forest-grassland mosaics are urgently needed.

Assessing the consistency of hotspot and hot-moment patterns of wildlife road mortality over time
Rodrigo Augusto Lima Santos, Fernando Ascensão, Marina Lopes Ribeiro, Alex Bager, Margarida Santos-Reis, Ludmilla M.S. Aguiar
Perspectives in Ecology and Conservation. 2017;15:56-60

  • Spatial and temporal aggregation patterns of roadkills are recurrently used to mitigate road impacts.

  • The aim of this study is to assess if hotspots/hot-moments remain in the same locations and periods over time and at different spatial and temporal scales.

  • Hotspots and hot-moments occurred over time, but at large temporal and spatial scales.

  • We suggest using longer road sections and longer time in order to minimize uncertainty.

  • Costs and benefits using different spatial and temporal units to detect WVA are similar.

Advances and barriers to the development of jaguar-tourism in the Brazilian Pantanal
Fernando R. Tortato, Thiago J. Izzo
Perspectives in Ecology and Conservation. 2017;15:61-3

  • Jaguar tourism contributes to economic and ecological sustainability of Pantanal.

  • The Pantanal is the only brazilian biome that has policies for wildlife tourism.

  • Government supervision applying tourism laws on Pantanal are limited.

  • The tourism basically is self regulated by the guides and tourism operators.

  • Pantanal has the potential to be an example to wildlife tourism development.
