Variation in community structure of gall-inducing insects associated with a tropical plant supports the hypothesis of competition in stressful habitats. [PDF]
Ecol Evol, 2019 Our assessment of the role of competition in structuring gall communities along a gradient of environmental stress advances the understanding of the role of environmental filters in biotic responses imposed by abiotic changes in a natural environment. Mesic environments favor the action of parasites and predators on gall communities, while competition ...

Sauvagesia (Ochnaceae) in the campos rupestres of the Espinhaço Range, Brazil [PDF]
Rodriguésia, 2023 The campos rupestres (rupestrian grasslands) of the Brazilian Espinhaço Range are renowned for harboring extraordinary plant diversity and endemism, yet many groups representative of this habitat remain taxonomically understudied.

Untangling biodiversity interactions: A meta network on pollination in Earth's most diverse tropical savanna. [PDF]
Ecol EvolWe addressed how pollination meta network with vertebrate and invertebrate species is assembled in the world's most diverse savanna and identified potential biogeographical bias within the region. We found a generalization of interactions at the meta network level but a high degree of specialization within the modules, where bees are the module ...

Hierarchical mapping of Brazilian Savanna (Cerrado) physiognomies based on deep learning [PDF]
, 2021 The Brazilian Savanna, also known as Cerrado, is considered a global hotspot for biodiversity conservation. The detailed mapping of vegetation types, called physiognomies, is still a challenge due to their high spectral similarity and spatial variability.

Functional traits of three major invasive grasses in a threatened tropical mountain grassland
Anais da Academia Brasileira de Ciências, 2021 The native flora of the Brazilian rupestrian grassland (campos rupestres) is threatened by the spread of invasive grasses. In this study, we evaluated the effect of habitat on the functional traits and CSR ecological strategies of three invasive alien ...

Evaluating the potential of biodiversity offsets to achieve net gain
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Evaluating the outcomes and tracking the trajectory of biodiversity offsets is essential to demonstrating their effectiveness as a mechanism to conciliate development and conservation. We reviewed the literature to determine the principles that should underpin biodiversity offset planning and the criteria for offset evaluation at the project ...
