Habitat modification mediates the strength of trophic cascades on oak trees
Angela A.Q. Chan, Cristina Banks-Leite
10.1016/j.pecon.2020.09.002

  • We investigated the strength of trophic cascades through bird exclusion.

  • Trophic cascades are three times stronger in forest interior than modified habitats.

  • Leaf damage, however, does not change with habitat modification.

  • Functional redundancy of birds may offset loss in their ecological function.

  • Riparian deforestation may strongly affect stream functioning, with consequences for biodiversity and ecosystem services.

  • We evaluated the effects of riparian deforestation on 1. measures of community structure using aquatic benthic invertebrates, and 2. an aspect of ecosystem functioning, aquatic leaf processing.

  • Both structural and functional measures changed with riparian deforestation: invertebrate diversity decreased and metrics changed as expected of a negative impact, and leaf processing decreased.

  • Thus both types of bioindicators were useful for monitoring changes and relating them to loss of biodiversity and ecosystem function.

Fragment size and the disassembling of local bird communities in the Atlantic Forest: A taxonomic and functional approach
Helon Simões Oliveira, Sidney F. Gouveia, Juan Ruiz-Esparza, Stephen F. Ferrari
10.1016/j.pecon.2020.09.003

  • As forest habitat loss progresses, functional overdispersion increases among related species.

  • The loss of forest habitat causes the local extinction of functionally similar bird species.

  • Removing functionally similar species leads to a reduction in functional redundancy.

  • Competition is more important than neutral processes in small forest habitat.

Level-2 ecological integrity: Assessing ecosystems in a changing world
Charles A. Martin, Raphaël Proulx
10.1016/j.pecon.2020.08.001

  • Measuring objectively the ecological integrity of an ecosystem is a complex task.

  • Deviation of an indicator variable from a reference relationship is a measure of integrity.

  • Plant biomass (indicator) is constrained by vegetation height (context variable).

  • Fragmentation (indicator) is constrained by the amount of habitats (context variable).

  • In the anthropocene, conservation goals must be set without pristine reference states.

Invasion by a non-native willow (Salix × rubens) in Brazilian subtropical highlands
Rafael Barbizan Sühs, Michele de Sá Dechoum, Silvia Renate Ziller
10.1016/j.pecon.2020.09.001

  • Salix × rubens (hybrid crack willow) is invading Brazilian riparian ecosystems

  • Most individuals occurred exclusively along watercourses and floodplains

  • Water transport can facilitate hybrid crack willow dissemination

  • Cultivation and transport must include measures to prevent biological invasions

  • Such measures have still not been established by the government

Unravelling effects of grazing intensity on genetic diversity and fitness of desert vegetation
Y. Ivón Pelliza, C.P. Souto, M. Tadey
10.1016/j.pecon.2020.06.005

  • Large herbivores cause genetic diversity loss between cohorts in a desert shrub.

  • Parental and offspring cohorts showed increasing inbreeding.

  • Livestock reduced seed set, seedling emergence and increased offspring mortality.

  • Unmanaged large exotic herbivores seriously affect dryland vegetation structure.

  • Disturbance jeopardize plant evolutionary potential thought complex effects.

Landscape changes decrease genetic diversity in the Pallas’ long-tongued bat
Rosane G. Collevatti, Luciana C. Vitorino, Thiago B. Vieira, Monik Oprea, Mariana P.C. Telles
10.1016/j.pecon.2020.06.006

  • The replacement of natural vegetation to agriculture, pastures or urban matrices decreased genetic diversity in the Palla’s long-tongued bat.

  • Pallas’s long-tongued bat had a quasi-stable range distribution since the last Glacial Maximum.

  • The Quaternary climate changes had no significant effects on the genetic diversity of the Palla’s long-tongued bat.

  • Populations of the Palla’s long-tongued bat was differentiated by isolation-by-distance, but not by environment.

  • Our findings point to the maintenance of large areas of natural vegetation to conserve genetic diversity in the Palla’s long-tongued bat.

A Model of Collaborative Governance for Community-based Trophy-Hunting Programs in Developing Countries
Inayat Ullah, Dong-Young Kim
10.1016/j.pecon.2020.06.004

  • Local communities cooperate and participate in CBTH programs due to power-imbalance between strong governments and weak communities who neighbor or live closely with wildlife.

  • Contingency propositions that help practitioners and governments to understand and implement projects that seek environmental conservation in collaboration with local communities.

  • Key components of community-based trophy hunting programs identified and defined.

  • Factors affecting CBTH program’s process that determine the outcomes of CBTH programs.

  • Identifying specific and quantitative objectives and linking them to timeframes and budgets.

  • Developing strategic monitoring and evaluation programs focussed on MPA performance.

  • Enabling local stakeholders to participate in planning processes.

  • Explicitly considering MPA costs and leveraging existing sources of funding.

  • Decentralizing resource management and empowering local stakeholders to manage resources sustainably.

Sugarcane: Brazilian public policies threaten the Amazon and Pantanal biomes
Mendelson Lima, Carlos Antonio da Silva Junior, Tatiane Deotti Pelissari, Thaís Lourençoni, Iago Manuelson Santos Luz, Francis Junior Araujo Lopes
10.1016/j.pecon.2020.06.002

  • Brazilian government liberates the sugarcane plantations in the Pantanal and the Amazon.

  • This non-sanctioned crop is likely to become the newest driver of deforestation in these biomes.

  • Direct and indirect conversion of forests can create a carbon balance debt that could take centuries to offset.
