Sedimentary ancient DNA and HBI biomarkers as sea‐ice indicators: A complementary approach in Antarctic fjord environments

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 785-795, December 2024.
Abstract Reliable high‐resolution, pre‐observational‐period sea‐ice datasets are rare but critical for contextualizing recent sea‐ice declines and future scenarios. We combine sedimentary ancient DNA of the sea‐ice dinoflagellate Polarella glacialis (Pgla‐sedaDNA) with selected highly branched isoprenoid (HBI) biomarkers alongside other indicators to ...

Lake regionalization and diatom metacommunity structuring in tropical South America

Ecology and Evolution, Volume 8, Issue 16, Page 7865-7878, August 2018., 2018
To group lake ecosystems that share local and regional environmental similarities as functional metacommunity units. Significant association between geographic clusters of lakes and diatom community composition. Relevance of functional‐based metacommunity model linked to dispersal for elucidating mechanisms behind latitudinal gradients.

Prey specificity of predatory venoms

Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.
