Abstract Tropical cyclones can highly modify coastal ecosystems through interactions between their unique set of meteorological traits and an ecosystem’s antecedent conditions. As such, resultant changes to biological community structure are likely storm-specific, yet our understanding cyclone effects on marine communities is limited compared in terrestrial freshwater habitats. Using Gulf Mexico (GOM) mesozooplankton data, we tested: (1) for differences storm non-storm dispersion; (2) if post-storm varied one another; (3) salinity drove differences; (4) physical drivers abundance evenness communities. Mesozooplankton following Hurricanes Harvey, Ike, Rita, during five years were analyzed. Post-Ike, post-Rita, similar while post-Harvey distinct. A structural equation model revealed stratification evenness. Post-Harvey more abundant low waters; a pattern muted all other years. NW GOM was generally resilient hurricane effects, except when large occurred. Our findings suggest resource availability planktivorous predators energy transfer within food webs altered with high precipitation rates.

Abstract Extreme wind events affect lake phytoplankton by deepening the mixed layer and increasing internal nutrient loading. Both increases decreases in concentration after strong have been observed, but precise mechanisms driving these responses remain poorly understood or quantified. We coupled a one‐dimensional physical model to biogeochemical investigate factors regulating short‐term summer events, now under expected warmer future conditions. simulated physical, chemical, biological dynamics Lake Erken, Sweden, found that could increase decrease euphotic zone 1 week event, depending on antecedent chemical Wind had little effect if was deep prior exposure.

These findings help better understand how impacts vary as function of local environmental conditions warming changing extreme weather will ecosystems.

Abstract Extreme wind storms can strongly influence short‐term variation in lake ecosystem functioning. Climate change is affecting by altering their frequency, duration, and intensity, which may have consequences for resistance resilience. However, catchment processes are simultaneously antecedent conditions shape the resilience landscape prior to storm exposure.

Between May and July 2018, Ireland experienced an exceptional heat wave, which broke long-term temperature drought records. These calm, stable conditions were abruptly interrupted by a second extreme weather event, Atlantic Storm Hector, in late June. Using high-frequency monitoring data, coupled with fortnightly biological sampling, we show that the storm directly affected stratification pattern of Lough Feeagh, resulting intense mixing event. The lake restabilised quickly after as heatwave continued. During there was three-fold reduction Schmidt stability, mixed layer deepening 9.5 m coinciding two-fold chlorophyll but increase total zooplankton biomass. Epilimnetic respiration increased net ecosystem productivity decreased. ratio nitrogen:total phosphorus from in-lake versus inflow rivers decoupled, leading to cascade effect on higher trophic levels. A step change nitrogen:phosphorus imbalances suggested community shifted nitrogen nutrient constraints. Such characterisations both thermal ecological responses events are relatively rare crucial our understanding how lakes changing impacts global climate accelerate.
