Phylogenetic conservatism in the relationship between functional and demographic characteristics in Amazon tree taxa

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 181-198, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf and wood functional traits of trees are related to growth, reproduction, and survival, but the degree of phylogenetic conservatism in these relationships is largely unknown.

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

Thermal plasticity has higher fitness costs among thermally tolerant genotypes of Tigriopus californicus

open access: yesFunctional Ecology, Volume 38, Issue 7, Page 1562-1577, July 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Under climate change, ectotherms will likely face pressure to adapt to novel thermal environments by increasing their upper thermal tolerance and its plasticity, a measure of thermal acclimation. Ectotherm populations with high thermal tolerance are often less thermally

Leveraging whole‐genome sequencing to estimate telomere length in plants

open access: yesMolecular Ecology Resources, Volume 24, Issue 2, February 2024.
Abstract Changes in telomere length are increasingly used to indicate species' response to environmental stress across diverse taxa. Despite this broad use, few studies have explored telomere length in plants. Thus, evaluation of new approaches for measuring telomeres in plants is needed.
