Patterns of frugivory in the columnar cactus Pilosocereus leucocephalus. [PDF]

Ecol Evol, 2019
Birds and bats feed on the fruit, and presumably disperse, the seeds of Pilosocereus leucocephalus, a keystone columnar cactus species in Mesoamerica Abstract In the frugivory networks of many arid and semi‐arid Mesoamerican ecosystems, columnar cacti act as keystone species that produce fruits with a high content of water and nutrients attractive to ...

Biotransformación de antibióticos en humedales artificiales: Rol de la interacción entre microorganismos y macrófitas

Ecología Austral, 2022
La cantidad de antibióticos vertidos en ecosistemas acuáticos va en aumento y repercute negativamente en la salud del ambiente y del ser humano. Entre los métodos que se usan para removerlos está la fitorremediación, una metodología basada en usar ...

Spatially resolved detection of small molecules from press‐dried plant tissue using MALDI imaging

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Matrix‐assisted laser desorption/ionization mass spectrometry imaging (MALDI‐MSI) is a chemical imaging method that can visualize spatial distributions of particular molecules. Plant tissue imaging has so far mostly used cryosectioning, which can be impractical for the preparation of large‐area imaging samples, such as full flower ...

Vertically stratified frugivore community composition and interaction frequency in a liana fruiting across forest strata

Biotropica, Volume 55, Issue 3, Page 650-664, May 2023., 2023
Our findings suggest a continuous shift in the frugivore community composition along the vertical gradient of a plant species fruiting across forest strata, from a few generalized frugivores in the understorey to a diverse set of specialized frugivores in the canopy.

Meta‐analysis of ecosystem services associated with oyster restoration

Conservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Restoration of foundation species promises to reverse environmental degradation and return lost ecosystem services, but a lack of standardized evaluation across projects limits understanding of recovery, especially in marine systems. Oyster reefs are restored to reverse massive global declines and reclaim valuable ecosystem services, but the ...

Predation risk can modify the foraging behaviour of frugivorous carnivores: Implications of rewilding apex predators for plant–animal mutualisms

Journal of Animal Ecology, Volume 91, Issue 5, Page 1024-1035, May 2022., 2022
Red fox (Vulpes vulpes) foraging placidly on Iberian pear fruits (Pyrus bourgaeana) in one fruit depot created for the field experiment of this study outside Iberian lynx (Lynx pardinus) ranges. Abstract Apex predators play key roles in food webs and their recovery can trigger trophic cascades in some ecosystems.

Seed fate in ant‐mediated dispersal: Seed dispersal effectiveness in the Ectatomma ruidum (Formicidae)—Zanthoxylum ekmanii (Rutaceae) system

Biotropica, Volume 54, Issue 3, Page 764-775, May 2022., 2022
Using the seed dispersal effectiveness framework, we tracked seed fate in a dispersal limited system finding that ant workers (Formicidae, Ectatomma ruidum) act as secondary dispersers for the pioneer tree Zanthoxylum ekmanii (Rutaceae) whose seeds have no visible adaptation for ant dispersal.
