Let's talk about sex: Why reproductive systems matter for understanding algae

open access: yesJournal of Phycology, Volume 60, Issue 3, Page 581-597, June 2024.
Abstract Sex is a crucial process that has molecular, genetic, cellular, organismal, and population‐level consequences for eukaryotic evolution. Eukaryotic life cycles are composed of alternating haploid and diploid phases but are constrained by the need to accommodate the phenotypes of these different phases.

Description and shaping factors of diet and feeding ecology of neotropical tadpoles: A case study and a comprehensive review

open access: yesAustral Ecology, Volume 49, Issue 1, January 2024.
We performed a systematic review on the available literature on in situ studies of neotropical tadpole diets focusing on diet composition and its sources of variation. Such studies approached in just a few instances the effects of seasonality, developmental stage and food selectivity on diet composition, but the available data indicate none of these ...
