  • Long-term monitoring of different drivers of changes increases the effectiveness of protected areas.

  • Long-term Ecological Research Program helps detecting complex environmental changes.

  • The effects of disturbances on biodiversity and ecosystems were explored over 22 years in the central Cerrado.

  • Even in Protected Areas, changes in surroundings affect biodiversity and ecosystems.

  • Significant ecological changes were detected in responses to long-term stressors.

  • We reviewed the use of network science in sustainable agriculture.

  • Network science can be used to understand, harness and restore ecological processes in agricultural systems.

  • Social, economic and ecological aspects of agriculture can be incorporated using novel methods.

  • Agricultural systems can be managed using a network-based framework.

Top-down local management, perceived contribution to people, and actual detriments influence a rampant human‒top predator conflict in the Neotropics
Santiago Zuluaga, F. Hernán Vargas, Sebastián Kohn, Juan M. Grande
Perspectives in Ecology and Conservation. 2022;20:91-102

  • Neotropical governments and their environmental agencies have generally poor governance.

  • Poor governance can be influencing human-top predator conflicts in the Neotropics.

  • Forty percent of interviewees disapproved the current top-down local management.

  • Disapproval of top-down local management influenced human tolerance independently.

  • Neotropics need a better balance between bottom-up and top-down governance.

Does spring bring colors? Seasonal bird plumage color variation along urban-rural gradients
Lucas M. Leveau
Perspectives in Ecology and Conservation. 2022;20:103-10

  • Bird color diversity increased during the breeding season.

  • The standardized effect size of bird color diversity did not change between seasons.

  • Urban areas presented the lowest color diversity along the year.

  • Bird color composition was stable between seasons in urban areas.

Landscape composition regulates the spillover of beneficial insects between forest remnants and adjacent coffee plantations
Hugo Reis Medeiros, Felipe Martello, Jean Paul Metzger, Karen Amanda Harper, Ximo Mengual, Ciro Abbud Righi, Milton Cezar Ribeiro
Perspectives in Ecology and Conservation. 2022;20:111-6

  • 9847 wasps classified into 75 species and 23 genera were recorded.

  • Inter-habitat dissimilarity decreased with increasing forest cover in the landscape.

  • Landscape diversity, edge density, and pesticide usage did not affect spillover.

  • Forested landscapes provide more spillover opportunities than do crop landscapes.

Trait shifts in bird communities from primary forest to human settlements in Mexican seasonal forests. Are there ruderal birds?
Leopoldo D. Vázquez-Reyes, Horacio Paz-Hernández, Héctor O. Godínez-Álvarez, María del Coro Arizmendi, Adolfo G. Navarro-Sigüenza
Perspectives in Ecology and Conservation. 2022;20:117-25

  • Anthropization drives directional changes on functional traits of bird communities of Neotropical seasonal forests.

  • Birds within anthropized habitat have short life cycles, rapid development, high fecundity, and broad ecological niches.

  • According to the Ecological Strategies Theory, birds could show the ruderal strategy within the perturbed anthropic habitat.

Projected responses of Cerrado anurans to climate change are mediated by biogeographic character
Gabriela Alves-Ferreira, Gastón Andrés Fernandez Giné, Danilo de Siqueira Fortunato, Mirco Solé, Neander Marcel Heming
Perspectives in Ecology and Conservation. 2022;20:126-31

  • Climate change threatens Cerrado anurans.

  • ∼70% of anuran species tend to lose potential distribution areas.

  • Not all species are likely to be equally affected by climate change.

  • Anurans’ responses to climate change are mediated by biogeographic character.

Divergent herb communities in drier and chronically disturbed areas of the Brazilian Caatinga
Ligia A.F. Vieira, Marcelo Tabarelli, Gustavo Souza, Rubens T. Queiroz, Bráulio A. Santos
Perspectives in Ecology and Conservation. 2022;20:132-40

  • Caatinga dry forests are becoming increasingly drier and chronically disturbed.

  • Herb communities negatively respond to rainfall reduction and increase disturbance.

  • Responses may be mediated by the local density of woody plants.

  • Multiple successional pathways should emerge with the new environmental conditions.

  • Management and conservation actions are urgent to protect Caatinga herb diversity.

From whom and for what? Deforestation in Dry Chaco from local-urban inhabitants’ perception
S. Marinaro, L. Sacchi, N.I. Gasparri
Perspectives in Ecology and Conservation. 2022;20:141-50

  • Agriculture-frontier classification allows organizing social-ecological processes.

  • Forest exploitation and real-estate transactions are daily drivers in the early stages.

  • Global agribusiness and livestock are drivers dominating the advanced stages.

  • Only crop replacement takes place during mature frontier stages.

  • Extra-regional people and governments are mentioned as the responsible social actors.

Neutral processes and reduced dispersal across Amazonian rivers may explain how rivers maintain species diversity after secondary contact
Sergio Santorelli Junior, William E. Magnusson, Cláudia Pereira de Deus, Timothy H. Keitt
Perspectives in Ecology and Conservation. 2022;20:151-8

  • Simulations show that neutral processes and reduced dispersal across rivers can maintain two species in allopatry for many generations.

  • Reduced dispersal maintained allopatry despite repeated river crossings allowing rivers to act as effective secondary barriers.

  • Neutral processes across contact zones provide a potential mechanism for the maintenance of Amazonian biodiversity.

  • More understanding of the dispersal characteristics of organisms and factors that limit river crossing are needed to make predictions about the role of rivers in maintaining Amazonian biodiversity.

Assessing the conservation of eastern Ecuadorian cloud forests in climate change scenarios
Alexander P.R.R. de Meyer, H. Mauricio Ortega-Andrade, Gabriel M. Moulatlet
Perspectives in Ecology and Conservation. 2022;20:159-67

  • The tropical montane cloud forests (TMCF) in Ecuador are endangered ecosystems that may be affected by climate change.

  • Community – level ecological niche models are useful to reconstruct TMCF boundaries to guide conservation strategies.

  • By year 2050, 42 -54 % TMCF area reduction and 207 – 429 m upwards elevational shift was predicted by our models.

  • TMCF model corresponds to 68% of the Ecuadorian ecosystem map, with transitional zones on adjacent montane ecosystems.

  • TMCF under protected areas might increase in future scenarios, as climatic suitability areas will move to higher elevations.

Protection status and density-dependent effects mediate the abundance-suitability relationship of a threatened species
Aline Cavalcante de Souza, Marcelo de Moraes Weber, Jayme Augusto Prevedello
Perspectives in Ecology and Conservation. 2022;20:168-76

  • The abundance-suitability relationship differs between protected and unprotected populations of Euterpe edulis.

  • The magnitude and direction of the relationship is modulated by population density.

  • The abundance-suitability relationship is positive only outside protected areas and in low-density populations.

  • Protection status and density-dependence should be incorporated into abundance-suitability models of threatened species.

Genetics and community-based restoration can guide conservation of forest fragments for endangered primates
María José Ruiz-López, Arleigh Jane Hitchcock, Noah D. Simons, Jenneca McCarter, Colin A. Chapman, Dipto Sarkar, Patrick Omeja, Tony L. Goldberg, Nelson Ting
Perspectives in Ecology and Conservation. 2022;20:177-83

  • There is no evidence of genetic population structure in Ashy red colobus monkeys inhabiting a highly fragmented landscape.

  • A “stepping stone” model could maintain connectivity between the main forest and the fragments improving the viability of red colobus populations.

  • Forest stepping stones can be established through restoration efforts of non-arable areas between fragments and the park.

  • A community-based forest restoration effort can benefit multiple stakeholders and increase the conservation value of forest fragments.
