Abstract Climate and land‐use changes are expected to increase the future occurrence of wildfires, with potentially devastating consequences for freshwater species ecosystems. Wildfires that burn in close proximity systems can significantly alter physicochemical properties water. Following wildfires heavy rain, must contend complex combinations wildfire ash components (nutrients, polycyclic aromatic hydrocarbons, metals), altered light thermal regimes, periods low oxygen together lead mass mortality events.

The mechanistic basis and adaptive significance of cross-tolerance: a ‘pre-adaptation’ to a changing world?

Journal of Experimental Biology, Journal Year: 2023, Volume and Issue: 226(11)

Published: June 1, 2023

ABSTRACT Protective responses are pivotal in aiding organismal persistence complex, multi-stressor environments. Multiple-stressor research has traditionally focused on the deleterious effects of exposure to concurrent stressors. However, encountering one stressor can sometimes confer heightened tolerance a second stressor, phenomenon termed ‘cross-protection’. Cross-protection been documented wide diversity taxa (spanning bacteria, fungi, plant and animal kingdoms) habitats (intertidal, freshwater, rainforests polar zones) response many stressors (e.g. hypoxia, predation, desiccation, pathogens, crowding, salinity, food limitation). Remarkably, cross-protection benefits have also shown among emerging, anthropogenic stressors, such as heatwaves microplastics. In this Commentary, we discuss mechanistic basis adaptive significance cross-protection, put forth idea that will act ‘pre-adaptation’ changing world. We highlight critical role experimental biology played disentangling interactions provide advice for enhancing ecological realism laboratory studies. Moving forward, benefit from greater focus quantifying longevity costs associated with protective response. This approach enable us make robust predictions species' complex environments, without making erroneous assumption all stress is deleterious.

Climate change amplifies the risk of potentially toxigenic cyanobacteria

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(18), P. 5240 - 5249

Abstract Cyanobacterial blooms pose a significant threat to water security, with anthropogenic forcing being implicated as key driver behind the recent upsurge and global expansion of cyanobacteria in modern times. The potential effects land‐use alterations climate change can lead complicated, less‐predictable scenarios cyanobacterial management, especially when forecasting toxin risks. There is growing need for further investigations into specific stressors that stimulate toxins, well resolving uncertainty surrounding historical or contemporary nature cyanobacterial‐associated To address this gap, we employed paleolimnological approach reconstruct abundance microcystin‐producing temperate lakes situated along human impact gradient. We identified breakpoints (i.e., points abrupt change) these time series examined landscape climatic properties on their occurrence. Our findings indicate subject greater influence exhibited an earlier onset biomass by 40 years compared less‐impacted lakes, emerging dominant predictor.

Changes and disturbances to water diversity quality are complex multi-scale in space time. Although situ methods provide detailed point information on the condition of bodies, they limited use for making area-based monitoring over time, as aquatic ecosystems extremely dynamic. Remote sensing (RS) provides data cost-effective, comprehensive, continuous standardised characteristics changes from local regional scales scale entire continents. In order apply better understand RS techniques their derived spectral indicators quality, this study defines five that can be monitored using RS. These traits, genesis, structural water, taxonomic functional water. It is essential record traits derive other four Furthermore, only most important interface between approaches.
