  • Fire incidence in Brazil increased in 2019−2020, with unprecedented magnitude in the Pantanal.

  • Fire effects vary according to the evolutionary history of the affected ecosystem.

  • A drier climate and land use changes increase the risk of wildfires throughout Brazil.

  • Poor governance further exacerbates the risk and damage of wildfires.

  • Fire policies must be improved by collaboration among different sectors of the society.

To graze or not to graze: A core question for conservation and sustainable use of grassy ecosystems in Brazil
Rodrigo Baggio, Gerhard E. Overbeck, Giselda Durigan, Valério D. Pillar
Perspectives in Ecology and Conservation. 2021;19:256-66

  • Grassy ecosystems in South America have developed under grazing by large herbivores until the Early Holocene.

  • The grassy biomes need grazing animals and/or fire to maintain their biodiversity and ecological characteristics.

  • Grazing in the Legal Reserve can represent a social process with benefits for land users and biodiversity conservation.

  • Knowledge on grazing in Brazil’s grassy ecosystems should be developed by researchers and stakeholders.

Selective logging in a chronosequence of Atlantic Forest: drivers and impacts on biodiversity and ecosystem services
José Alberes Santos da Cunha, Nathan Castro Fonsêca, Jéssica Stéfane Alves Cunha, Lúcia dos Santos Rodrigues, Reginaldo Augusto Farias de Gusmão, Ana Carolina Borges Lins-e-Silva
Perspectives in Ecology and Conservation. 2021;19:286-92

  • Selective logging impacts biodiversity and ecosystem services in a chronosequence.

  • Two types of drivers lead the exploitation: forest supply and access.

  • Logging is higher in forests with higher tree abundance and biomass.

  • Forest areas with lesser supply but easier accessed are also exploited.

  • Harvest occurs in more accessible areas, and its intensity depends on the supply.

Cat and dog predation on birds: The importance of indirect predation after bird-window collisions
Natalia Rebolo-Ifrán, Lucía Zamora-Nasca, Sergio A. Lambertucci
Perspectives in Ecology and Conservation. 2021;19:293-9

  • Domestic cats (Felis silvestris catus) and dogs (Canis lupus familiaris), affect birdlife in various ways, including predation.

  • Besides direct predation, birds caught by cats and dogs after collisions with windows represents an unexplored human cause of avian mortality.

  • Bird-window collisions should be incorporated into the assessment of bird predation by cats and dogs.

  • Minimizing the number of cats and dogs per household and the time spent outdoors would help reduce avian mortality.

William D. Simonson, Ellen Miller, Alastair Jones, Shaenandhoa García-Rangel, Hazel Thornton, Chris McOwen
Perspectives in Ecology and Conservation. 2021;19:300-10

  • Climate change needs considering in seven areas of restoration design/implementation.

  • These range from objective setting through to monitoring and adaptive management.

  • Evidence is scant for climate change resilient restoration in practice.

  • Our framework can help structure a more climate change resilient restoration approach.

Perspectives in Ecology and Conservation. 2021;19:311-8

  • Private reserves preserve the environmental heterogeneity found in the PEC.

  • Mammals, in general, are the least studied vertebrate groups in the PEC.

  • The western region of the PEC presents the highest sampling relevance of vertebrates.

  • Sites with the highest sampling relevance are most threatened by fragmentation.

Environmental sound as a mirror of landscape ecological integrity in monitoring programs
Camilo Sánchez-Giraldo, Camilo Correa Ayram, Juan M. Daza
Perspectives in Ecology and Conservation. 2021;19:319-28

  • We determined how soundscape complexity and ecological integrity are related.

  • Acoustically richer soundscapes were linked to higher ecological integrity.

  • Relationship between acoustic complexity and integrity was influenced by daily variation.

  • Acoustic complexity serves as an indicator of the ecosystem health.

  • Soundscape analysis is a feasible approach for monitoring and conservation of the landscape.

  • Brazilian Merganser has few suitable areas remaining for its three populations.

  • Several small hydroelectric plants are planned in areas where the species inhabits.

  • A high amount of suitable area used by the species is not within Protected Areas.

  • A fifth of the suitable areas are covered by anthropogenic land use, mainly pasture.

  • Brazilian Merganser situation is critical, calling for urgent conservation actions.

Integrating farmers’ decisions on the assessment of forest regeneration drivers in a rural landscape of Southeastern Brazil
Mónica Borda-Niño, Eliane Ceccon, Paula Meli, Diego Hernández-Muciño, Jean-François Mas, Pedro H.S. Brancalion
Perspectives in Ecology and Conservation. 2021;19:338-44

  • Forest regeneration is frequent on steeper slopes (>10%) formerly used for cattle ranching.

  • Forest regeneration is frequent closer to older forest patches and permanent rivers.

  • Biophysical factors as slope and altitude affect farmer’s decisions on land abandonment.

  • Forest regeneration is inversely related to the economic dependence on farm’s income.

  • Fluctuating market demands can encourage deforestation or land abandonment.

Climate and land-use changes coupled with low coverage of protected areas threaten palm species in South Brazilian grasslands
Licet Fernanda Calambás-Trochez, Santiago José Elías Velazco, Pablo Melo Hoffmann, Elivelton Marcos Gurski, Fernanda Thiesen Brum, Marcos Bergmann Carlucci
Perspectives in Ecology and Conservation. 2021;19:345-53

  • The palm species of the South Brazilian grasslands are at risk.

  • In this region, climate and land-use changes increase threats to palm species.

  • The synergistic effects of these threats increase the risk of extinction of species.

  • With no future dispersal, palm species are likely to face a drastic range reduction.

  • Current protected areas in the region are not sufficient to protect palm species.

André Luís de Gasper, Guilherme Salgado Grittz, Carlos Henrique Russi, Carlos Eduardo Schwartz, Arthur Vinicius Rodrigues
Perspectives in Ecology and Conservation. 2021;19:369-78

  • Most tree ferns will lose suitable areas due to climate change.

  • Dicksonia sellowiana Hook. may become more threatened as a result of constraints in its distribution.

  • In all scenarios, subtropical tree ferns assemblages in the Atlantic Forest will become less rich.

  • Neglecting the uncertainties arising from the choice of global circulation models can lead to inaccurate conclusions.

Pierre Chassé, Cécile Blatrix, Nathalie Frascaria-Lacoste
Perspectives in Ecology and Conservation. 2021;19:379-86

  • Scientific interest is necessary but insufficient when determining protected areas.

  • French procedures for creating protected areas show various land-use conflicts.

  • A clear understanding of implementation decisions is necessary to reach conservation goals.

  • Local authorities can constitute a proxy to seize conservation opportunities.

  • Social sciences and interdisciplinary research are necessary for resolving conservation issues.

Free-roaming domestic cats near conservation areas in Chile: Spatial movements, human care and risks for wildlife
María José López-Jara, Irene Sacristán, Ariel A. Farías, Francisca Maron-Perez, Francisca Acuña, Emilio Aguilar, Sebastián García, Patricio Contreras, Eduardo A. Silva-Rodríguez, Constanza Napolitano
Perspectives in Ecology and Conservation. 2021;19:387-98

  • Domestic cats move far away from the household infrequently.

  • Cats often used native forest (12% of fixes), overlapping with guignas (L. guigna).

  • House proximity to forest edge (>200 m) strongly predicts the use of forest by cats.

  • Land subdivision, low human care and lack of control can exacerbate cats' impacts.
