Ectomycorrhizal fungi and the nitrogen economy of <i>Nothofagus</i> in southern Patagonia. [PDF]
Ecol EvolEctomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Hydrological Processes, Volume 37, Issue 5, May 2023., 2023 Hydrological and biogeochemical datasets made available in the Zenodo platform for two catchments in Montseny (Catalonia, Spain) for the period 1978–2018. Abstract We present here, and make freely available, two long‐term datasets on the hydrology and hydrochemistry of two small catchments totally or partially covered by holm oak (Quercus ilex) forests.

Biotropica, Volume 54, Issue 5, Page 1226-1237, September 2022., 2022 Animal‐pollinated plants interact with neighbors for both abiotic resources and pollination, but few studies have compared the relative magnitude of these effects, particularly in agroecosystems. This study evaluated the effects of neighboring plants at three vertical strata (herbs, coffee bushes, and canopy trees) on pollen deposition, fertilization ...

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.

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores
Ecological Solutions and Evidence, Volume 3, Issue 2, April–June 2022., 2022 Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

Wildlife collection for scientific purposes
Conservation Biology, Volume 35, Issue 1, Page 5-11, February 2021., 2021 Abstract Illegal transfer of wildlife has 2 main purposes: trade and scientific research. Trade is the most common, whereas scientific research is much less common and unprofitable, yet still important. Biopiracy in science is often neglected despite that many researchers encounter it during their careers.
