Abstract. Warm-water coral reefs are facing unprecedented human-driven threats to their continued existence as biodiverse functional ecosystems upon which hundreds of millions people rely. These impacts may drive past critical thresholds, beyond the system reorganises, often abruptly and potentially irreversibly; this is what Intergovernmental Panel on Climate Change (IPCC, 2022) define a tipping point. Determining point thresholds for reef requires robust assessment multiple stressors interactive effects. In perspective piece, we draw recent global revision initiative (Lenton et al., 2023a) literature search identify summarise diverse range interacting that need be considered determining warm-water ecosystems. Considering observed projected stressor impacts, endorse revision's conclusion mean surface temperature (relative pre-industrial) threshold 1.2 °C (range 1–1.5 °C) long-term atmospheric CO2 concentrations above 350 ppm, while acknowledging comprehensive stressors, including ocean warming response dynamics, overshoot, cascading have yet sufficiently realised. already been exceeded, therefore these systems in an overshoot state reliant policy actions bring levels back within limits.

Invasive alien species are a primary driver of biodiversity loss and extinction. Smooth cordgrass (Spartina alterniflora) is one the most aggressive invasive plants in coastal ecosystems around world. However, genomic bases evolutionary mechanisms underlying invasion success this remained largely unknown. Here we assembled chromosome-level reference genome performed phenotypic population analysis between native US introduced Chinese populations. Our comparisons showed that populations evolved competitive traits, such as early flowering time greater plant biomass, during secondary introductions along China's coast. Population transcriptomic inferences revealed distinct trajectories low- high-latitude In particular, genetic mixture among different source together with independent natural selection acting on target genes might have resulted high dynamics study provides novel evidence how smooth rapidly adapts to variable environmental conditions its ranges. Moreover, candidate related time, fast growth stress tolerance (i.e., salinity submergence) provide valuable resources for future improvement other cereal crops.

Abstract As offshore wind energy developments increase globally in response to climate change, it is important gain an understanding of the effects they are having on marine environment. Whilst there growing information types organisms present within these sites, our knowledge how species interact with sites limited. For first time we examined movements and habitat utilization a temperate decapod, European Lobster Homarus gammarus, using acoustic telemetry farm (OWF). Innovasea V9 transmitters were externally attached 33 individuals (carapace length = 87–113 mm) at three turbine locations Irish Sea. Individuals found exhibit high residency tagging over half tagged lobsters for 70% study period. Individual home ranges core territories calculated 95% 50% kernel density, respectively. Home ranged from 9313.76 23 156.48m2 while 1084.05 6037.38m2. Over all detections recorded 35 m scour protection. These results suggest that particular areas fixed-turbine OWFs provide suitable lobsters. We postulate this likely result artificial reef arising addition hard substate into previously soft sediment dominated habitats. Therefore, future OWF across Europe may potential fishery opportunities as effects.
