Disentangling the rationale of deforestation to understand better the partial effectiveness of protected areas. A case study for Madagascar's eastern rainforest corridor (2001-12) [PDF]

, 2015
Madagascar's notoriously high level of biodiversity is currently threaten by deforestation. Protected Areas (hereafter “PAs”) remain until now the central instrument to protect it whilst little is known about their environmental effectiveness in the ...

A protracted phenology: Post‐diapause larval development of a threatened butterfly

Insect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

Evolutionary response of Caragana (Fabaceae) to Qinghai-Tibetan Plateau uplift and Asian interior aridification [PDF]

, 2010
Caragana is endemic to temperate Asia, with most species distributed on the Qinghai-Tibetan Plateau (QTP) and in Northwestern China. Consequently its biogeography should be hypothesized to have been affected by QTP uplift.

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

Physiological Entomology, EarlyView.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

IUCN Red List Regional Assessment of the Flora of Niue Utilising Indigenous Local Knowledge and Botanical Information

Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
A regional assessment of the indigenous vascular plants of Niue is presented using the IUCN Red List criteria. The assessment was undertaken during a community workshop that drew on the indigenous local knowledge and scientific information. The assessment comprised 197 named taxa and 8 indeterminate entities, with 4 (2.0%) taxa assessed as Extinct and ...

Recurrent hybridization underlies the evolution of novelty in Gentiana (Gentianaceae) in the Qinghai-Tibetan Plateau

AoB Plants, 2020
The Qinghai-Tibetan Plateau (QTP) and adjacent areas are centres of diversity for several alpine groups. Although it is known that the QTP acted as a source area for diversification of the alpine genus Gentiana, the evolutionary processes underlying ...

The effect of drought stress on the limits and costs of plasticity in floral longevity in response to pollinator decline

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Declines in pollinator populations can reduce pollination services to plants, resulting in lower seed production. In response to these reductions, plants could increase the probability of pollinator visitation by plastically extending floral longevity.

Distribution, structural and ecological aspects of the unusual leaf nectaries of Calolisianthus species (Gentianaceae) [PDF]

, 2011
Nectaries in leaves of Gentianaceae have been poorly studied. The present study aims to describe the distribution, anatomy, and ecological aspects of extrafloral nectaries (EFNs) of three Calolisianthusspecies and in particular the ultrastructure of EFNs
