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

Journal 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.

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse

Conservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Journal of Ecology, Volume 110, Issue 9, Page 2219-2231, September 2022., 2022
Litter mixing did not have strong effects on decomposition rates across the studied climatic gradient overall, and the direction and intensity of the mixture effects were context dependent. The effects were stronger and more negative in the dryer ecosystems.

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

Functional 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 ...

Randomized clinical trial of the effect of intraoperative humidified carbon dioxide insufflation in open laparotomy for colorectal resection

BJS Open, Volume 4, Issue 1, Page 45-58, February 2020., 2020
Open abdominal surgery leads to peritoneal desiccation and damage, resulting in inflammation. This peritoneal damage can be mitigated by the use of warmed, humidified carbon dioxide. Peritoneal inflammation and open surgery Background Animal studies have shown that peritoneal injury can be minimized by insufflating the abdominal cavity with warm ...
