Ecological and morphological determinants of evolutionary diversification in Darwin's finches and their relatives. [PDF]

Ecol Evol, 2020
The ecological diversification of Darwin's finches is unmatched on the same archipelago by any other clade of colonising land birds. For all morphological traits, we observe an early pulse of diversification followed by prolonged periods of slower steady‐state rates of change for the tanager family a substantial increase in speciation rate in Darwin's ...

Exploring landowners' perceptions, motivations and needs for voluntary conservation in a cultural landscape

People and Nature, Volume 2, Issue 3, Page 840-855, September 2020., 2020
Abstract While efforts to reverse the current global environmental crisis increase, we are still experiencing unprecedented rates of species' extinctions. Traditional cultural landscapes can potentially play an important role for biodiversity conservation globally.

Spatial Variation in Bird Community Composition in Relation to Topographic Gradient and Forest Heterogeneity in a Central Amazonian Rainforest

International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012
We investigated the effects of landscape features and forest structure on the avian community at the Reserva Florestal Adolpho Ducke near Manaus, in the Brazilian Amazon. We sampled the landscape and forest in 72 50 × 50 m plots systematically distributed in the reserve, covering an area of 6,400 ha.
