Macroclimatic niche similarity and species relatedness shift their influence on species co‐occurrence in bryophyte forest communities across scales

Journal of Ecology, Volume 113, Issue 6, Page 1546-1559, June 2025.
The relationship between epiphytic bryophyte species associations changes with scale. Macroclimatic niche similarity strongly influences co‐occurrence globally but less so at smaller scales. Most species interactions are positive or neutral across scales, though ~7% shift from positive at microhabitat to negative at regional scales, highlighting scale ...

Microgeographic body size variation in a high elevation Andean anole (Anolis mariarum; Squamata, Polychrotidae)

Revista de Biología Tropical, 2009
Intra-specific body size variation is common and often is assumed to be adaptive. Studies of body size variation among sites should include or consider environmental and ecological variables in their designs. Additionally, reciprocal transplant or common

Geographic variation in developmental plasticity among populations of the canyon treefrog in response to temperature and pond‐drying

Journal of Zoology, Volume 324, Issue 2, Page 103-117, October 2024.
This study focuses on the responses of the canyon tree frog (Dryophytes arenicolor) larvae to temperature and pond‐drying. Conducting a common garden experiment with larvae from three distinct populations, we found significant geographic variation in plastic responses and observed that populations exhibit specific responses to each treatment in both ...

Intraspecific variation in body size and shape in an Andean highland anole species, Anolis ventrimaculatus (Squamata: Dactyloidae)

Revista de Biología Tropical, 2013
Variation in body characteristics related to lizard locomotion has been poorly studied at the intraspecific level in Anolis species. Local adaptation due to habitat heterogeneity has been reported in some island species.

Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Functional Ecology, Volume 38, Issue 4, Page 955-966, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and water loss through stomatal conductance and is key for understanding dryland plant responses to climate change.
