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.

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.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

open access: yesOikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Chilean jagged lobster, Projasus bahamondei, in the southeastern Pacific Ocean: current state of knowledge

open access: yesLatin American Journal of Aquatic Research, 2014
The Chilean jagged lobster (Projasus bahamondei) is a deep-water crustacean (175-550 m) occurring in certain areas of the southeastern Pacific Ocean, including the Nazca Ridge, Desventuradas Islands, the Juan Fernandez archipelago and ridge, and the ...

High β‐diversity in fig wasp communities driven by species turnover in widely distributed Neotropical fig trees

open access: yesOikos, EarlyView.
Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

open access: yesOikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Control sustentable poscosecha: extractos de Larrea cuneifolia mediados por nades frente a Botrytis cinerea [PDF]

open access: yes, 2019
Botrytis cinerea es un hongo ubicuo que ocasiona la podredumbre gris, una de las principales enfermedades de fruta en poscosecha, siendo responsable de pérdidas económicas. Debido a la creciente preocupación por los efectos adversos del uso de pesticidas,
