Sensitisation patterns in legume hypersensitivity. A study from the central region of Portugal [PDF]

open access: yes, 2009
Background: Foods from the legume family are used in the Mediterranean diet as a source of protein. In some cases, their ingestion triggers potentially life -threatening reactions.

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.

Nitrogen fixing legumes and their partners in Brazil : from the lab to the field, from the forest to the mine tailing [PDF]

open access: yes, 2012
Leguminosae, the third largest family of angiosperms, are of major agricultural, ecological and economic importance. Several recent studies allowed to clarify the taxonomic and phylogenetic relationships among the 19,400 species that constitute this ...

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

open access: yesOikos, EarlyView.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Vicia incisa (Fabaceae). Taxonomical and chorological notes [PDF]

open access: yes, 2017
The classification of the Vicia sativa aggregate is unsatisfactory. Concerning the taxonomic value and choice of rank of some of these taxa, there are disagreements among botanists.

Is a plant truly plastic? Nutrients and neighbours induce trait‐specific responses, but performance depends on response direction

open access: yesOikos, EarlyView.
Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

X-ray tomography as a tool for detailed anatomical analysis [PDF]

open access: yes, 2009
Wood identification, anatomical examination and retrieval of quantitative information arc important aspects of many research disciplines. Conventional light microscopy with a camera and (semi)automatic image analysis software is an often used methodology

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased
