Brazil’s democracy and sustainable agendas: A nexus in urgent need of strengthening
Geraldo Wilson Fernandes, Fabio de Oliveira Roque, Stephannie Fernandes, Carlos Eduardo de Viveiros Grelle, José Manuel Ochoa-Quintero, Tiago Shizen Pacheco Toma, Evaldo Ferreira Vilela, Philip Martin Fearnside

  • Brazil's actual government faces many challenges in implementing sustainable agendas.

  • Building synergy among sectors relies on trans-ministerial dialog.

  • The attempted coup in Brazil evidences a critical governance-conservation imbalance.

  • Persistent threats to the environmental agenda demand that we stay vigilant.

  • National instruments aimed at biodiversity conservation need to be secured.

Global change explains the neotropical rattlesnake Crotalus durissus (Serpentes: Viperidae) range expansion in South America
Gabriela Ferreira Campos Guerra, Mariana Moncassim Vale, Rodrigo Tardin, Daniel Silva Fernandes
Perspectives in Ecology and Conservation. 2023;21:200-8

  • The Neotropical cascabel has been expanding its range since the 1950’.

  • A number of hypothesis to explain the expansion have been raised, but none tested.

  • We show that land use change is the main driver of this expansion.

  • Climate change also has a (smaller) role on the phenomenon.

Functionally connecting collaring and conservation to create more actionable telemetry research
Robert A. Montgomery, Lara A. Boudinot, Tutilo Mudumba, Özgün Emre Can, Egil Droge, Paul J. Johnson, Darragh Hare, Matt W. Hayward
Perspectives in Ecology and Conservation. 2023;21:209-15

  • Telemetry technology has revolutionized ecological research.

  • Comparable impacts to conservation science, however, are presently unclear.

  • Conservation is an applied discipline where impacts drive new policies and practices.

  • Frameworks to functionally connect collaring and conservation are presented.

  • The ways in which these frameworks can yield conservation gains are discussed.

Does agricultural intensification impact pest regulation service by frogs in a natural multi-trophic system?
Deyatima Ghosh, Parthiba Basu
Perspectives in Ecology and Conservation. 2023;21:216-23

  • Frog density below a certain threshold cannot regulate rice pest population irrespective of agricultural intensity.

  • Due to strong intraguild predation between amphibians and arthropod pest predators, pest regulation is suppressed.

  • At advanced crop growth stage increased foliage provides refuge to pests causing a switch in prey preference of the frogs towards more agile arthropod pest predators.

  • Improving habitat heterogeneity will increase the frog density in the landscape and improve pest regulation.

Anthropogenic factors do not affect male or female jaguar habitat use in an Amazonian Sustainable Reserve
Anelise Montanarin, Emiliano Esterci Ramalho, Daniel Gomes da Rocha, Diogo Maia Gräbin, Guilherme Costa Alvarenga, Pedro Aurélio Costa Lima Pequeno, Fabricio Beggiato Baccaro, William Ernest Magnusson
Perspectives in Ecology and Conservation. 2023;21:224-30

  • We evaluated jaguar habitat use accounting for individual non-independence.

  • We did not find habitat-use differences between jaguar sexes in Amazonian varzea.

  • Anthropogenic influence apparently had little effect on overall jaguar habitat use.

  • Our results differ from previous studies that did not account for individual differences.

  • Local human settlements within the Mamirauá Sustainable Development Reserve appear to have low impact on jaguars.

Immediate impact of fires on roadkilling of wild vertebrates on a highway in southeast Brazil
Cláudio Lacet, Natalie Olifiers, Cecília Bueno
Perspectives in Ecology and Conservation. 2023;21:231-6

  • Wild vertebrate roadkills increased by about 144% after fires along the highway.

  • Roadkills in sections affected by fires were higher than on neighboring sections.

  • An experimental design with temporal and spatial controls should be adopted.

  • Fires must be considered when formulating measures to mitigate wild vertebrate roadkilling.

Global biogeographical patterns of ants and their abiotic determinants
Anderson Dantas, Carlos Roberto Fonseca
Perspectives in Ecology and Conservation. 2023;21:237-46

  • Estimated ant species richness is higher in the tropical region.

  • Estimated ant species richness was best explained by annual rainfall and mean temperature.

  • The direction and effect of abiotic determinants are relative to the zoogeographic realm analyzed, highlighting regional effects.

Estimating mammal density from track counts collected by Indigenous Amazonian hunters
Michael S. Esbach
Perspectives in Ecology and Conservation. 2023;21:247-52

  • Monitoring programs must produce reliable estimates of density for conservation.

  • For many species, tracks occur more frequently than visual encounters on transects.

  • This study tests a method to estimate mammal density based on track detections.

  • Indigenous hunters with expert knowledge and skills collected the data.

Optimizing survey effort for Euglossine bees in tropical forests
Juliana Hipólito, William E. Magnusson, Fabricio Baccaro
Perspectives in Ecology and Conservation. 2023;21:253-62

  • Sample design for scent traps must be as effective as possible without depleting bees.

  • Orchid bee species composition was related to soil phosphorus content.

  • Optimizing sampling effort is crucial for biodiversity preservation.
