Area‐restricted search under realistic constraints
Oikos, EarlyView.Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Oikos, EarlyView.An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Demonstrating limitations of area‐restricted search as a foraging mechanism
Oikos, EarlyView.Foragers often rely on simple behavioral rules that translate local environmental cues into movement decisions. One of the most widespread rules is area‐restricted search (ARS), in which movement becomes less directional following resource encounters. ARS is generally considered effective for exploiting clustered resources, yet recent conceptual work ...

Fenología reproductiva y tolerancia a temperaturas altas en Stenocereus queretaroensis
Polibotánica, 2017 Numerosas especies de cactáceas presentan frutos comestibles, por lo que han adquirido un papel importante dentro de la agricultura de zonas áridas y semiáridas, tanto para el comercio regional como para el internacional.

PLANTS, PEOPLE, PLANET, EarlyView.Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Aquella "Tacita magica" que disfrutamos
Revista de Salud Pública, 2014 Varias leyendas han tratado de explicar durante muchos siglos, el origen del arbusto de cafeto. Extendido en la actualidad por el mundo entero, la bebida fabricada con los frutos, es consumida casi por todos sus habitantes.

PLANTS, PEOPLE, PLANET, EarlyView.Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Anais da Academia Brasileira de Ciências, 2014 The study was carried out to verify if there are differences in foraging frequency and behavior of Apis mellifera in two melon hybrids (10:00 – ‘Yellow melon’ and Sancho -‘Piel de Sapo’) in the municipality of Juazeiro, state of Bahia, Brazil.
