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

open access: yesApplications 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

open access: yesBiotropica, 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

open access: yesConservation 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

open access: yesJournal 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

open access: yesBiotropica, 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.

Cuerpos de cobre: Extractivismo en Chuquicamata, Chile

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 26, Issue 2, Page 200-218, June 2021., 2021
Resumen ¿Qué extraen y qué producen los extractivismos? El presente artículo intenta responder a esta pregunta analizando críticamente, la relación entre cuerpos, trabajo y mi‐nería principalmente bajo el modelo neoliberal chileno, en la mina estatal de cobre a tajo abierto más grande del planeta: Chuquicamata.

Can we manage marine mammal bycatch effectively in low‐data environments?

open access: yesJournal of Applied Ecology, Volume 58, Issue 3, Page 596-607, March 2021., 2021
Here we develop three alternative methods that expand the toolbox of approaches available for use in determining marine mammal conservation reference points for human‐caused mortality when it is not possible to apply the more standard, data‐hungry Potential Biological Removal approach.

Can variation in seed removal patterns of Neotropical pioneer tree species be explained by local ant community composition?

open access: yesBiotropica, Volume 53, Issue 2, Page 619-631, March 2021., 2021
We combined observations of seed removal by ants with a characterization of the above‐ and below ground ant communities at five sites on Barro Colorado Island, Panama, to determine if seed removal patterns were associated with local ant community structure.

Determination of biosorption mechanism in biomass of agave, using spectroscopic and microscopic techniques for the purification of contaminated water [PDF]

open access: yes, 2019
[Abstract] Lead (Pb2+) and copper (Cu2+) are polluting metals due to their toxicity; however, the extraction of these metals is essential for economic development, so it is important to look for efficient and low-cost alternatives that can remove heavy ...

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

open access: yesEcol 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 ...
