Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(Elsevier Science, 2017-09)
Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ...

Are all patches worth exploring? Foraging desert birds do not rely on environmental indicators of seed abundance at small scales
(BioMed Central, 2019-06)
Background: Consumers should show strong spatial preferences when foraging in environments where food availability is highly heterogeneous and predictable. Postdispersal granivores face this scenario in most arid areas, ...
Pre-dispersal seed loss in two Prosopis species (Fabacea: Mimosoidea) from the Monte Desert, ArgentinaPérdida de semillas en fase de pre-dispersión en dos especies de Prosopis (Fabacea: Mimosoidea) del Desierto del Monte, Argentina
(Asociación Argentina de Ecología, 2018-08)
Los filtros impuestos sobre las semillas en la fase pre-dispersiva pueden alterar su probabilidad de ser dispersadas. Evaluamos la pérdida de semillas debido a la depredación por insectos y aborción durante la etapa ...
Efectos de la fragmentatión sobre la aborción y depredación de semillas en el Chaco Serrano
(Wiley Blackwell Publishing, Inc, 2004-03)
Las interacciones entre plantas e insectos pueden ser afectadas por la fragmentación de los hábitats. En este estudio, realizado en el Chaco Serrano de Argentina, investigamos los efectos de la fragmentación sobre la ...
Can achene selection in sunflower crop–wild hybrids by pre-dispersal seed predators hasten the return to phenotypically wild sunflowers
(2016-04)
Bird attack is a serious limitation to sunflower yield in several regions of the world, but it could also cause selection. The wild Helianthus annuus, naturalized in several regions of the world, hybridizes with the crop ...
Are silvopastoral systems compatible with forest regeneration? An integrative approach in southern Patagonia
(2013-12)
We used an integrated approach to analyze the influence of silvopastoral management on the biotic and abiotic factors influencing on the natural recruitment of native forests in Tierra del Fuego (Argentina). The probabilities ...
Experimental reduction of plant abundance changes interaction frequency of a tri-trophic micro-food web: contrasting responses of generalists and specialists
(Wiley Blackwell Publishing, Inc, 2019-09)
Species abundance is vulnerable to climate change and anthropogenic impact. Although numerous studies have examined the food web response to species loss, their response (e.g. in network topology and interaction frequency) ...
