Oribatid assemblies of tropical high mountains on some points of the “Gondwana-Bridge” – a case study [PDF]

, 2008
This work is the first part of a series of studies, which introduces the methodological possibilities of coenological and zoogeographical indication and – following the climate, vegetation and elevation zones – the pattern-describing analysis of the main

Monsanima tinguaensis (Apocynaceae), an enigmatic new species from Atlantic rainforest

Phytotaxa, 2014
A new species of Asclepiadoideae (Apocynaceae) with enigmatic taxonomic position was found in the Atlantic rainforest of Rio de Janeiro State, southeastern Brazil. To ascertain its affinities within the Asclepiadeae, we performed phylogenetic analyses using the plastid regions trnT-L and rps16.

Stable isotope data indicate origins of mislabelled historical bird specimens

Ibis, EarlyView.
Natural history specimens provide valuable insights across diverse research fields, but those needing more accurate metadata have limited scientific value. We applied stable isotope analysis to investigate the origin of 19th century Atlantic Forest bird specimens attributed to the northeastern Brazilian state of Pernambuco, which are the only records ...

Global congruence of carbon storage and biodiversity in terrestrial ecosystems [PDF]

, 2009
Deforestation is a main driver of climate change and biodiversity loss. An incentive mechanism to reduce emissions from deforestation and forest degradation (REDD) is being negotiated under the United Nations Framework Convention on Climate Change.

Taxonomic, phylogenetic and functional diversity patterns of Saturniidae moth communities along a tropical forest recovery gradient in Ecuador

Insect Conservation and Diversity, EarlyView.
Diverse Saturniidae moth communities are found in naturally recovering tropical forests in Ecuador. Community composition showed a gradual turnover with strongest differences between old‐growth forest and active agriculture, but only weak differences in taxonomic, phylogenetic and functional diversity. While our results suggest that Saturniidae are not

Variations in water use by a mature mangrove of Avicennia germinans, French Guiana [PDF]

, 2009
In the tropical intertidal zones, little is known on water uptake by mangroves. Transpiration rates are generally measured at leaf level, but few studies exist on water use at tree or stand levels.

Cudbear and the Colours of the Atlantic Rainforest

Heritage
The temperate rainforests and their associated coastline in Scotland have long been home to dye-producing plants including lichens, some commercialised and patented by George and Cuthbert Gordon in 1758 as the dye Cudbear. Using merchant records and family correspondence, this paper will shed new light on the early trade and manufacture of Cudbear and ...

Do the recent severe droughts in the Amazonia have the same period of length? [PDF]

, 2015
We propose a new measure based on drought period length to assess the temporal difference between the recent two severe droughts of 2005 and 2010 in the Amazonia.

Politicisation and Agricultural (Post‐)Exceptionalism in EU–Mercosur Association Agreement Negotiations

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This article examines how the politicisation of EU trade policy – defined by heightened public salience, stakeholder polarisation and contestation – reshapes agricultural lobbying strategies, with a particular focus on the EU–Mercosur Association Agreement.
