A new species of Neonella Gertsch, 1936 is described from Uruguay: N. almita n. sp., which inhabits natural grasslands. Additionally, first records of N. acostae Rubio, Argañaraz & Gleiser, 2015, and new records of N. lubrica Galiano, 1988, N. minuta Galiano, 1965, and N. montana Galiano, 1988 are given. Illustrations of the habitus, sexual charact...

Agyneta hum Cajade, Rodrigues & Simó n. sp. and Agyneta unguiserrata Cajade n. sp. are described and illustrated from Brazil and Uruguay based on males and females. Males of A. hum differ from the related A. adami (Millidge 1991) by having apical and posterior pocket of paracymbium, presence of dorsal tibial apophysis and the shape and surface of t...

Los escarabajos estercoleros pueden influenciar la emergencia y supervivencia de plántulas. Sin embargo, la dirección y la magnitud de este efecto dependerá de los atributos funcionales de la comunidad de escarabajos estercoleros y de las condiciones ambientales dominantes. Estudiamos el rol de los escarabajos estercoleros en la dispersión de semil...

Inflorescence movements in response to natural gradients of sunlight are frequently observed in the plant kingdom and are suggested to contribute to reproductive success. Although the physiological and molecular bases of light-mediated tropisms in vegetative organs have been thoroughly investigated, the mechanisms that control inflorescence orienta...

Plants are able to detect the presence of neighbours by sensing the variation in the proportion of red and far red light (around 660 nm and 740 nm, respectively) in their surrounding ambient. The phytochromes are the main photoreceptors involved in neighbour detection, and regulate several physiological processes that modulate plant shape and archi...

Dung beetles use a variety of vertebrate dung to provision their offspring. To locate these resources, dung beetles use volatile substances emitted from dung as cues. Although it has been shown in laboratory tests that dung beetles are able to discriminate between different dung types using dung volatiles as kairomones, the attraction of particular...

The fast touch-induced folding of leaves in sensitive plants may function for deterring herbivores, but it relies on energetically costly action potentials and interferes with photosynthesis. Here, we tested whether the intensity of the folding response in Mimosa pudica was modulated based on previous experiences, and whether the modulation was dep...

A key to 24 Staphylinidae species associated with decaying carcasses in Argentina is presented, including diagnoses, illustrations, distributional and bionomical data for these species. This article provides a table of all species associated with carcasses, detailing the substrate from which they were collected and geographical distribution by prov...

Previous studies have examined separately how pollinator generalization and abundance influence plant reproductive success, but none so far has evaluated simultaneously the relative importance of these pollinator attributes. Here we evaluated the extent to which pollinator generalization and abundance influence plant reproductive success per visit...

Recent studies of plant-animal mutualistic networks have assumed that interaction frequency between mutualists predicts species impacts (population-level effects), and that field estimates of interaction strength (per-interaction effects) are unnecessary. Although existing evidence supports this assumption for the effect of animals on plants, no st...
