Biocrusts increase the resistance to warming-induced increases in topsoil P pools. [PDF]

J Ecol, 2022
Our findings provide novel insights on the responses of soil P pools to warming and rainfall reduction, and highlight the importance of biocrusts as modulators of these responses in dryland ecosystems. Our results suggest that the observed negative impacts of warming on dryland biocrust communities will decrease their capacity to buffer changes in ...

Claw growth rates in a subset of adult, indoor, domestic cats (Felis catus). [PDF]

Vet Dermatol
Background – Keratinised tissues, such as nails and claws, accumulate hormones over time; the claws' hormone concentrations are being explored as potential biomarkers. Timelines for hormone deposition can be established if claw growth rates are known. Hormone concentration within cat claws has been recently evaluated, yet the growth rates of cat claws ...

Safety and efficacy of laxatives after major abdominal surgery: systematic review and meta-analysis. [PDF]

BJS Open, 2020
Routine postoperative laxative use after major abdominal surgery may result in earlier passage of stool, but does not influence other postoperative recovery parameters. Better data are required for postoperative complications and validated outcome measures.

ARABIDOPSIS HOMOLOG OF TRITHORAX1 impacts lateral root development by epigenetic regulation of targets involved in root system architecture. [PDF]

New Phytol
Summary Developmental processes are regulated at multiple levels, including the epigenetic level. Among the epigenetic factors, histone H3 lysine 4 (H3K4) methyltransferases contribute to active transcription of target genes, and here, we explored how the H3K4 methyltransferase ARABIDOPSIS HOMOLOG OF TRITHORAX1 (ATX1) affects Arabidopsis thaliana ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal 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 ...

Long‐term hydrological and biogeochemical datasets from a Mediterranean forest site (Montseny, NE Spain)

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.

Integrating effects of neighbor interactions for pollination and abiotic resources on coffee yield in a multi‐strata agroforest

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 ...

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.

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.
