Abstract In biologically diverse ecosystems, an essential process to support competing species coexist is ecological differentiation. Habitat heterogeneity is, hence, important in establishing abundance and richness, favoring the coexistence of due habitat partition. this context, shading thermal tolerance can be good factors elucidate role partition among closely related species. Herein, we study effects microhabitat selection, behavior, physiological limitation on two fiddler crabs ( Leptuca leptodactyla uruguayensis ). Indeed, conditions influenced proportion over time, with L. more associated nonshaded/warmer areas while shaded/cooler ones. They also adjusted their behavior differently from each other deal stress. Finally, have demonstrated that these are species' limitations. We conclude such as intertidal regions estuaries (e.g., mudflats mangroves), between by reducing competition

Heatwaves have increased in intensity, duration and frequency over the last decades due to climate change. Intertidal species, living a highly variable environment, are likely be exposed such heatwaves since they can emerged for more than 6 h during tidal cycle. Little is known, however, on how temperature affects species traits (e.g. locomotion behaviour) of slow-moving organisms as benthic foraminifera (single-celled protists), which abound marine sediments. Here, we examine influences motion-behaviour metabolic dominant temperate Haynesina germanica by exposing individuals usual (6, 12, 18, 24, 30 °C) extreme (high; i.e. 32, 34, 36 regimes.

According to the metabolic theory of ecology, rate, an important indicator pace life, varies with body mass and temperature due internal physical constraints. However, various ecological factors may also affect rate its scaling mass.

The increasing frequency and intensity of marine heatwaves (MHWs) observed worldwide entails changes in the structure functioning ecological communities. While severe extreme often have more destructive effects, subtle effects moderate strong may nevertheless affect ecosystem through complex, context-dependent linkages between different processes. Here we conducted a laboratory experiment to study repeated short-term, MHWs on macrofauna bioturbation associated solute fluxes as measure using natural soft-sediment communities from Baltic Sea. Our results showed both biogeochemical cycling nutrients following heatwaves, which seemed contribute an enhanced degradation organic matter seafloor exchange solutes across sediment-water interface well increased sediment oxygen consumption.

Climate change impacts on mangroves have received considerable attention due to rising temperatures, sea level and greenhouse gas concentrations, changes in ocean circulation precipitation patterns, increasing extreme weather events. Mangrove responses depend whether critical thresholds are reached. High temperatures low lead warming events, driving mangrove mortality. Sea-level rise (SLR) will be the prime driver of future with a threshold ~6 mm a−1. Predicted rates expected exceed this at intermediate (10 Gt CO2 a−1) very high (~124 emission scenarios.

Abstract Heatwaves affect tidal flat ecosystems by altering the bioturbating behavior of benthic species, with potential consequences for sediment oxygenation, particle mixing, and erodibility. Although frequency duration heatwaves are expected to increase under global warming scenarios, we lack insights into how heatwaves' temporal dynamics behaviors. Using widely distributed bioturbator Cerastoderma edule as model quantified identical heat‐sum but different (i.e., 3‐ vs. 6‐d heating normal temperature cycles) behaviors mixing processes in mesocosms. Our results show that short frequent 3‐d heatwave cycles increased magnitude behaviors, thereby resulting more bio‐mixed than observed infrequent prolonged cycles. This unexpected result could be ascribed weakening health condition indicated a high death rate (47.37%) no‐heatwave control Present findings reveal impact on bioturbation will strongly depend future heatwaves: enhanced unless exceeds species resistance increases mortality.
