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 ...

Seasonality in niche occupation revealed through bird community functional structure in the southern Atlantic rainforest

Ibis, Volume 165, Issue 3, Page 986-997, July 2023., 2023
Seasonal variation in tropical and subtropical systems can have different effects on bird species depending on the resources they use and how they use them. However, despite recent research advances, knowledge of the drivers of the presence and abundance of species in different seasons is still limited for most tropical bird species.

The surrounding landscape shapes the abundance of Sphaerophoria scripta and Melanostoma mellinum (Diptera: Syrphidae) in Portuguese vineyards

Agricultural and Forest Entomology, Volume 25, Issue 2, Page 206-216, May 2023., 2023
Sphaerophoria scripta and Melanostoma mellinum are the most abundant species in vineyards. Seminatural habitats and other crops promote the abundance of S. scripta and M. mellinum in the vineyards. The presence of artificial territory and vineyards (at 1000 m), and olive orchards (at 500 m), in the landscape can reduce the abundance of M.

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

Ecology and Evolution, Volume 13, Issue 4, April 2023., 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

Resisting agrarian neoliberalism and authoritarianism: Struggles towards a progressive rural future in Mozambique

Journal of Agrarian Change, Volume 23, Issue 1, Page 185-203, January 2023., 2023
Abstract After nearly two and a half decades with a Land Law widely considered progressive, Mozambique is preparing to revise its legal framework for land. Land activists accuse the government of pursuing an authoritarian approach, excluding civil society participation, and falsifying public consultations.

Updating new invasions: The Australian tortoise beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) in the Iberian Peninsula

Journal of Applied Entomology, Volume 146, Issue 9, Page 1217-1223, November 2022., 2022
Abstract Trachymela sloanei (Blackburn, 1897) is a non‐indigenous beetle of the Iberian Peninsula herbivorous of several species of Eucalyptus trees. Since its first detection in Europe in 2014, little information is available about the populations of this beetle in this distribution range.

How do large wildfires impact sediment redistribution over multiple decades?

Earth Surface Processes and Landforms, Volume 47, Issue 13, Page 3033-3050, October 2022., 2022
In this study, we simulated the effect of wildfire recurrence on sediment dynamics in the Águeda catchment (404 km2, north‐central Portugal) over a 41‐year timespan. Wildfires with a large extent of particularly moderate and high severity cause significant increases in net erosion and multiple wildfires increased sediment build‐up in the catchment.

Condicionantes históricos do processo de degradação do ambiente natural na bacia hidrográfica do rio Biguaçu - SC

Acta Scientiarum: Technology, 2000
A bacia hidrográfica do rio Biguaçu foi ocupada por imigrantes alemães, açorianos e um contingente de escravos africanos. Os alemães se estabeleceram na região do Alto Biguaçu e os açorianos nas baixadas dos vales e mais tarde próximo à foz do rio ...

Distribuição espacial de peixes em ambientes lênticos: interação de fatores

Acta Scientiarum: Biological Sciences, 2008
Para o entendimento da estrutura e dinâmica das assembléias de peixes em ambientes lênticos, é fundamental identificar e analisar os principais fatores que se relacionam com as estratégias de ocupação do espaço físico pelas espécies, bem como ...
