Report of a floral visitor of Cypripedium irapeanum (Orchidaceae) in Tepoztlán, Morelos, Mexico

open access: yesPolibotánica, 2018
The process and participating actors of pollination have fascinated many scholars since the time of Darwin. Nevertheless, for many species of orchids, the identity of the pollinator or the purpose of floral visits remains unknown.

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.

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

open access: yesOikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Resource limitation and competition shape reproductive allocation and synchrony

open access: yesOikos, EarlyView.
The dynamics of reproductive allocation (RA) in herbaceous plant communities, particularly in response to varying environmental conditions such as drought stress and competitive interactions, remain underexplored. This study aims to fill this gap by hypothesising that both belowground resource limitation and the presence of dominant species ...

Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

open access: yesOikos, EarlyView.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.
