The Sonozotz project: Assembling an echolocation call library for bats in a megadiverse country. [PDF]

open access: yesEcol Evol, 2020
The Sonozotz project represents the first nation‐wide library of bat echolocation calls for a megadiverse country. Abstract Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications.

Seasonality regulates the structure and biogeochemical impact of ectomycorrhizal fungal communities across environmentally divergent neotropical dry forests

open access: yesJournal of Ecology, Volume 111, Issue 8, Page 1598-1613, August 2023., 2023
These results highlight the importance of seasonality and plant community composition in shaping different aspects of SDTF ECM fungal community structure and diversity as well as the potential for both the plant and fungal components of ECM symbioses to impact soil functioning across heterogenous SDTFs.

The dark web trades wildlife, but mostly for use as drugs

open access: yesPeople and Nature, Volume 5, Issue 3, Page 999-1009, June 2023., 2023
Abstract Contemporary wildlife trade is massively facilitated by the Internet. By design, the dark web is one layer of the Internet that is difficult to monitor and continues to lack thorough investigation. Here, we accessed a comprehensive database of dark web marketplaces to search across c. 2 million dark web advertisements over 5 years using c. 7 k

Communities of endophytic fungi in a Puerto Rican rainforest vary along a gradient of disturbance due to Hurricane Maria

open access: yesEcology and Evolution, Volume 12, Issue 12, December 2022., 2022
Even more than a year after the catastrophic passage of Hurricane Maria, communities of endophytic symbionts in a Puerto Rican rainforest bear a signature of forest disturbance. Abstract Increases in the frequency and intensity of hurricanes influence the structure, function, and resilience of Caribbean forests.

Biocrusts increase the resistance to warming‐induced increases in topsoil P pools

open access: yesJournal of Ecology, Volume 110, Issue 9, Page 2074-2087, September 2022., 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 ...

Broad‐ and small‐scale environmental gradients drive variation in chemical, but not morphological, leaf traits of vascular epiphytes

open access: yesFunctional Ecology, Volume 36, Issue 8, Page 1858-1872, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Variation in leaf functional traits along environmental gradients can reveal how vascular epiphytes respond to broad‐ and small‐scale environmental gradients. Along elevational gradients, both temperature and precipitation likely play an important role as drivers of ...

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

open access: yesJournal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Chemical and microbiological stability of diluted ceftazidime in three different solutions under three storage temperatures over a 28 day period

open access: yesVeterinary Dermatology, Volume 32, Issue 5, Page 456-e124, October 2021., 2021
Background – Ceftazidime (CAZ) solutions are being used based on anecdotal reports for otitis externa complicated by multidrug‐resistant Pseudomonas aeruginosa (MDR PA). The chemical and microbiological stability of these proposed compounded solutions have not been evaluated, and likely are affected by the diluent and storage duration or temperature ...
