Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

open access: yesOikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Fluxos de óxido nitroso em solos com cobertura de Floresta Ombrófila Densa Montana na Serra dos Órgãos, Rio de Janeiro

open access: yesQuímica Nova, 2012
Soil fluxes of N2O were determined over one year in montane tropical rainforest of southeastern Brazil with average annual rainfall of 2.8 m. Annual mean (± standard deviation) and median N2O fluxes were 3.0 ± 1.4 and 2.7 µg N m-2 h-1, respectively, is 5-

Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Conversion of rainforest to oil palm and rubber plantations alters energy channels in soil food webs

open access: yesEcology and Evolution, 2019
In the last decades, lowland tropical rainforest has been converted in large into plantation systems. Despite the evident changes above ground, the effect of rainforest conversion on the channeling of energy in soil food webs was not studied.

Additions to the bryophyte flora of Réunion (East African Islands) [PDF]

open access: yes, 2000
Nineteen species of bryophytes are reported for the first time for Réunion. Especially remarkable are the first African record of Anastrophyllum leucocephalum (Tayl.) Steph. and the first records for the East African Islands of Cephaloziella cf. vaginans

Understanding smallholder decision‐making to increase farm tree diversity: Enablers and barriers for forest landscape restoration in Western Kenya

open access: yesPeople and Nature, EarlyView.
Abstract Integrating diverse trees and shrubs (hereafter ‘trees’) in agricultural landscapes has emerged as a crucial nature‐based solution to the triple challenge of biodiversity loss, climate change and food security. The potential benefits of on‐farm trees for both people and nature, however, are often constrained by inadequate consideration of ...

Multi-objective optimisation of bio-based thermal insulation materials in building envelopes considering condensation risk [PDF]

open access: yes, 2018
The reduction in energy demand for heating and cooling with insulation materials increases the material related environmental impact. Thus, implementing low embodied energy materials may equilibrate this trade-off.

Conserving wildlife through demand reduction and supply alternatives: Two experiments in restaurants in Kinshasa

open access: yesPeople and Nature, EarlyView.
Abstract High aggregate levels of wildlife consumption in cities in Central Africa highlight the need for solutions that balance wildlife protection, local livelihoods and the relational values between people and nature. This study explores the impacts of demand‐ and supply‐side interventions on wild meat consumption through two randomized control ...

Modelling chemistry in the nocturnal boundary layer above tropical rainforest and a generalised effective nocturnal ozone deposition velocity for sub-ppbv NOx conditions [PDF]

open access: yes, 2010
Measurements of atmospheric composition have been made over a remote rainforest landscape. A box model has previously been demonstrated to model the observed daytime chemistry well. However the box model is unable to explain the nocturnal measurements of
