Forest conversion into pasture selects dung beetle traits at different biological scales depending on species pool composition. [PDF]

Ecol Evol, 2023
Briefly, we assess the impacts of forest conversion on the functional diversity of dung beetles in two different regions of Brazil, considering in particular intraspecific variation. To do this we conducted standardized surveys in seven forest fragments and adjacent pastures for every region and measured fourteen traits in individuals collected in each

Bee Body Size and Foraging Behavior Predict the Pollination Role of Bees in a Buzz-Pollinated Plant Community. [PDF]

Ecol Evol
We investigated how bee traits influence pollination success in a buzz‐pollinated plant community. Larger body size and floral sonication strongly predicted stigma contact, a proxy for pollination efficiency, while longer handling times were associated with reduced effectiveness.

Successful recovery of native plants post-invasive removal in forest understories is driven by native community features. [PDF]

Ecol Appl
Abstract Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long‐term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants.

Assessing the mechanisms and impacts of shrub invasion in forests: A meta‐analysis

Journal of Applied Ecology, Volume 60, Issue 11, Page 2314-2326, November 2023., 2023
Taken together, these results suggest that restoration efforts should focus on (i) increasing the presence of strong native competitors or functionally diverse native communities, (ii) decreasing sources of invasive shrub propagules while keeping the canopies closed when invasion occurs via high propagule pressure, (iii) avoiding management techniques ...

Value of human‐modified forests for the conservation of canopy epiphytes

Biotropica, Volume 54, Issue 4, Page 958-968, July 2022., 2022
Although HMFs provide important refuge for many species, our results show that they do not provide suitable conditions for the maintenance of current or future canopy epiphyte communities. Our findings suggest that conserving large continuous old‐growth forests is the only viable conservation option for protecting most vascular epiphytes.

Why forest fails to recover after repeated wildfires in Amazonian floodplains? Experimental evidence on tree recruitment limitation

Journal of Ecology, Volume 109, Issue 10, Page 3473-3486, October 2021., 2021
Our experimental evidence suggests that soil nutrient limitations may slow down forest recovery after repeated wildfires in Amazonian floodplains. Yet, because floodplain trees are able to germinate from seeds and establish successfully in twice burnt forests, seed limitation seems to be the reason why forest recovery fails persistently. Seeding native

Rapid evolution of a floral trait following acquisition of novel pollinators

Journal of Ecology, Volume 109, Issue 5, Page 2234-2246, May 2021., 2021
We test whether the acquisition of a new pollinator functional group (hummingbirds) can lead to rapid evolution of flowers after the recent trans‐continental range expansion of Digitalis purpurea. In naturalised populations in two separate regions in the Americas, we found convergent changes and strong selection for larger proximal corolla tubes, a ...

Caracterização fenotípica e parâmetros genéticos de mirtáceas nativas da Floresta Atlântica

Scientia Plena, 2023
A avaliação de recursos genéticos de espécies frutíferas nativas da Floresta Atlântica é fundamental para a sua introdução em programas de conservação e de melhoramento genético. O objetivo deste trabalho foi realizar a caracterização fenotípica e a avaliação de parâmetros genéticos e de correlações de frutos de acessos de araçaúna, cabeludinha ...

Riqueza e densidade de aves que nidificam em cavidades em plantações abandonadas de eucalipto

Papéis Avulsos de Zoologia, 2015
Monoculturas de árvores, como as de espécies de eucalipto, têm substituído florestas naturais, impactando a fauna pela perda de habitat e recursos. Diversas espécies de aves necessitam de ocos em árvores para nidificar. A falta de recursos como cavidades

Agrupamento e caracterização anatômica da madeira de espécies nativas da Floresta Ombrófila Mista [PDF]

Rodriguésia, 2019
Resumo Na Floresta Ombrófila Mista adicionalmente à diversidade florística, estudos sobre a diversidade anatômica da madeira de espécies nativas são interessantes pois permitem ampliar nosso conhecimento sobre a flora local. Portanto, este trabalho objetivou caracterizar anatomicamente e avaliar as similaridades e as principais características ...
