Ice in the intertidal: patterns and processes of freeze tolerance in intertidal invertebrates

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(14)

Published: July 15, 2024

Many intertidal invertebrates are freeze tolerant, meaning that they can survive ice formation within their body cavity. Freeze tolerance is a fascinating trait, and understanding its mechanisms important for predicting the survival of animals during extreme cold weather events. In this Review, we bring together current research on ecology, biochemistry physiology group freeze-tolerant organisms. We first introduce ecology zone, then highlight strong geographic taxonomic biases literature topic. Next, detail knowledge used by invertebrates. Although in terrestrial arthropods have been well-explored, marine invertebrate less well understood does not appear to work similarly because osmotic differences come with living seawater. thought be utilized include: (1) low molecular weight cryoprotectants, such as compatible osmolytes anaerobic by-products; (2) high ice-binding proteins; (3) other involving heat shock proteins aquaporins. Lastly, describe untested hypotheses, methods approaches researchers use fill gaps. Understanding consequences zone has many ecological implications, but also provides an opportunity broaden our more generally.

Roles of multi-level temperature-adaptive responses and microhabitat variation in establishing distributions of intertidal species

Journal of Experimental Biology, Journal Year: 2023, Volume and Issue: 226(21)

ABSTRACT How intertidal species survive their harsh environment and how best to evaluate forecast range shifts in distribution are two important closely related questions for ecologists global change biologists. Adaptive variation responses of organisms environmental across all levels biological organization – from behavior molecular systems is key importance setting patterns, yet studies often neglect the interactions diverse types (e.g. differences thermal optima owing genetic acclimation-induced effects) with variation, notably at scale microhabitats. Intertidal have cope extreme frequently changing stress, shown high sensitivities adaptive different organization. Here, I review physiological biochemical adaptations temperature on multiple spatial temporal scales. With fine-scale datasets limits individuals microhabitat scale, we can map sensitivity each individual microhabitats, then up analysis population level and, finally, by incorporating traits into models. These more refined mechanistic models that include consideration variations higher predictive power than these variations, they will be crucial answering posed above concerning mechanisms roles play governing patterns a rapidly world.

Variability and connectivity in populations of different limpet species across rockpool-generated mosaic landscapes

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Limpets are keystone grazers on rocky shores. We studied spatial patterns of four co-occurring patellids ( Patella ulyssiponensis , depressa rustica vulgata ) and one siphonariid Siphonaria pectinata across rockpools their surrounds. Our approach considered each rockpool as a concentric system three micro-habitats where limpets were censused (species, counts, size individuals): inside rockpool, edge zone, surrounding open-rock. The whole intertidal zone was sampled six shores with contrasting landscape variability (amount open-rock other micro-habitats) in Southwest Portugal. Additionally, surfaces far away (>25cm) from surveyed the mid-shore.

Assessment of polonium-210 bioaccumulation in Mediterranean limpet Patella caerulea (Linnaeus, 1758) and sea urchin Paracentrotus lividus (Lamarck, 1816) from different coastal areas of Türkiye: Inclusion of a seasonal investigation

Ege Journal of Fisheries and Aquatic Sciences, Journal Year: 2024, Volume and Issue: 41(4), P. 273 - 279

Published: Dec. 11, 2024

This study investigated the seasonal variations of polonium-210 (²¹⁰Po) activity concentrations in two marine invertebrate species: Mediterranean limpet (P. caerulea) and sea urchin lividus). Seasonal sample collection was conducted across three Aegean Sea Marmara coastal stations from December 2018 to October 2019. The included İzmir-Urla, Karaburun, İstanbul Island-Kınalıada. To assess size-dependent bioaccumulation ²¹⁰Po, individuals were categorized into size groups. both species exhibited fluctuations, ranging 4.9 ± 3.4 Bq kg⁻¹ dry weight 28.0 8.4 limpets 8.7 6.1 58.0 18.5 urchins. highest ²¹⁰Po consistently observed spring all sampling locations.
