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 ...

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.

Root foraging strategies and niche segregation of three mediterranean shrub species
Oikos, Volume 2024, Issue 11, November 2024.Shrubs are usually adapted to stressful environments in which soil resources are limited, and thus, roots are fundamental for their biological success. However, root measures are challenging to collect, especially in field conditions and at the individual level.

Fish species ecology in spanish freshwater ecosystems [PDF]
, 1992 The life strategies of the Iberian ichthyofauna, poor in species and with a high number of endemisms, are the result of the functioning of the aquatic systems (streams and reservoirs).

Aquaculture, Fish and Fisheries, Volume 4, Issue 2, April 2024.Abstract The presence of wild fish in and around aquaculture habitats is often assumed a response to food resources within these habitats, either from input feed, the presence of cultured species, and/or the assemblage of biofouling that naturally colonises aquaculture structures.

Baseline for ostracod-based northwestern Pacific and Indo-Pacific shallow-marine paleoenvironmental reconstructions: ecological modeling of species distributions [PDF]
Biogeosciences, 2019 Fossil ostracods have been widely used for Quaternary paleoenvironmental reconstructions, especially in marginal marine environments (e.g., for water depth, temperature, salinity, oxygen levels, pollution).

Ecological Monographs, Volume 94, Issue 1, February 2024.Abstract The contribution of genetic adaptation and plasticity to intraspecific phenotypic variability remains insufficiently studied in long‐lived plants, as well as the relevance of neutral versus adaptive processes determining such divergence. We examined the importance of phylogeographic structure and climate in modulating genetic and plastic ...
