nlstimedist: An r package for the biologically meaningful quantification of unimodal phenology distributions

Methods in Ecology and Evolution, Volume 10, Issue 11, Page 1934-1940, November 2019., 2019
Abstract Phenological investigation can provide valuable insights into the ecological effects of climate change. Appropriate modelling of the time distribution of phenological events is key to determining the nature of any changes, as well as the driving mechanisms behind those changes.

How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

Journal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Functional intraspecific variation in the base water potential for seed germination along soil microclimatic gradients

Functional Ecology, Volume 39, Issue 3, Page 897-911, March 2025.
Abstract The ability of plants to successfully regenerate depends on complex physiological and ecological processes, and one of the first vital stages is seed germination, which depends on temperature, light and water availability. Within species variation in seed germination allows differential responses when facing stimuli and is key for adaptation ...

Identificación de nuevos genes relacionados con la resistencia y germinación de esporos de B. subtilis

, 2023
La presencia de esporos bacterianos pone en peligro la inocuidad y calidad de los alimentosen los que se encuentran, debido a que producen su deterioro y algunos de ellos proceden deespecies patógenas. Los esporos poseen una alta resistencia a diversos agentes de conservación,siendo únicamente los tratamientos térmicos capaces de producir su muerte.La ...

Microclimatic variation regulates seed germination phenology in alpine plant communities

Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.
This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.

Effects of manakin gut passage on germination of a neotropical melastome shrub (Melastomataceae)

Biotropica, Volume 57, Issue 1, January 2025.
In a paired germination experiment, we found that manakin gut passage accelerated germination of a common and widespread Melastome shrub, Miconia rubescens, which may function as an important pioneer in regenerating rainforest. Manakin species varied in their gut passage effects and within species, body mass correlated with greater and earlier ...
