The physiological resilience of fern sporophytes and gametophytes: advances in water relations offer new insights into an old lineage

Frontiers in Plant Science, 2013
Ferns are some of the oldest vascular plants in existence and they are the second most diverse lineage of tracheophytes next to angiosperms. Recent efforts to understand fern success have fo-cused on the physiological capacity and stress tolerance of ...

Fern spore dispersal: A methodological review and experimental field study

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract Spore dispersal is one of the most important but perhaps the least investigated and understood processes in determining the geographical distribution of fern species. After a methodological review of the aerobiology of fern spores, we examined the impact of spore characteristics and meteorological factors on their airborne dispersal.

Cyanogenesis prospection in galled and non-galled tissues of Microgramma squamulosa (Polypodiaceae)

Lilloa, 2020
Cyanogenic glycosides are defense substances that can produce hydrocyanic acid when they undergo hydrolysis as a result of herbivory, a process called cyanogenesis.

Tropical Montane Cloud Forests Have High Resilience to Five Years of Severe Soil Drought

Global Change Biology, Volume 32, Issue 1, January 2026.
A 5‐year throughfall exclusion experiment in a Peruvian tropical montane cloud forest reduced soil moisture by 69%, leading to lower photosynthetic inputs and autotrophic respiration but maintaining net primary productivity and carbon sink capacity. Trees responded through metabolic downregulation, reduced fruit production, increased wood density, and ...

Retaining biodiversity in intensive farmland: epiphyte removal in oil palm plantations does not affect yield. [PDF]

, 2015
The expansion of agriculture into tropical forest frontiers is one of the primary drivers of the global extinction crisis, resulting in calls to intensify tropical agriculture to reduce demand for more forest land and thus spare land for nature ...

Morphological traits and environmental preferences of the Blunt‐headed tree snake Imantodes cenchoa: the effects of sex and ontogeny

Journal of Zoology, Volume 328, Issue 1, Page 41-51, January 2026.
Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.
