Leaf litter arthropod responses to tropical forest restoration. [PDF]
Soil and litter arthropods represent a large proportion of tropical biodiversity and perform important ecosystem functions, but little is known about the efficacy of different tropical forest restoration strategies in facilitating their recovery in degraded habitats.

Ants associated with fronds of the tropical bracken fern Pteridium esculentum subsp. arachnoideum
Abstract: Pteridium is a cosmopolitan genus of ferns that possess nectaries on its fronds (fern leaves), thereby attracting ants. Foliar (or extrafloral) nectaries are nectar-producing glands that are not related to pollination, but rather attract ants and other arthropods.

Remnant trees and forest fragments in agricultural landscapes can be important sources of propagules to facilitate forest recovery. However, many studies simply quantify forest cover in the surrounding landscape as a percentage, with little attention given to species composition, and subsequently fail to detect an effect on recruitment patterns.

Growth of Tropical Bracken (Pteridium arachnoideum): Response to Weather Variations and Burning [PDF]
AbstractThe ecology of tropical bracken, which occurs in tropical regions, is not well known. We studied its response to weather variations and burning in the south Ecuadorian Andes, where this weed had already overgrown 40% of the pastureland. In field observations, a constant 1 : 1 ratio of emerging and dying leaves suggested limitation of frond ...

Fern flora of Viçosa, Minas Gerais State, Brazil: Dennstaedtiaceae, Lindsaeaceae and Saccolomataceae
As part of an ongoing project treating the ferns and lycophytes from the region of Viçosa, Minas Gerais State, Brazil, we here present the taxonomic treatment of the early divergent lineages of the leptosporangiate ferns: the families Dennstaedtiaceae ...

Our simulation of decision‐making under uncertainty shows that accounting for multiple ecosystem services (ES) in addition to socio‐economic objectives has heterogeneous effects on tropical land‐use allocation. It saves some natural forest if the initial natural forest share is below 38%, and can stop deforestation once the natural forest share drops ...
