  摘要：In 2023, a record-setting marine heat wave triggered the ninth mass coral bleaching event on Florida's Coral Reef (FCR). We examined spatial patterns of heat exposure along the similar to 560-kilometer length of FCR and the mortality of two ecologically important, critically endangered reef-building corals. Sea surface temperatures were >= 31 degrees C for an average of 40.7 days, leading to heat exposures 2.2- to fourfold higher than all prior years on record. In the Florida Keys and Dry Tort...
• Invasion impacts in terrestrial ecosystems: Global patterns and predictors AI翻译

  摘要：Biological invasions can alter ecosystems, yet their impacts vary across ecological contexts. Using a global meta-analysis of 775 studies (2223 effect sizes) in terrestrial systems, we show that the most consistent negative impacts are reductions in native plant diversity caused by invasive plants and increases in greenhouse gas emissions driven by both invasive plants and animals. However, evidence of publication bias suggests the latter should be interpreted with caution. Invader residence t...

  摘要：Protein-protein interactions (PPIs) are essential for biological function. Coevolutionary analysis and deep-learning (DL)-based protein structure prediction have enabled comprehensive PPI identification in bacteria and yeast, but these approaches have had limited success for the more complex human proteome. We overcame this challenge by enhancing the coevolutionary signals with sevenfold-deeper multiple sequence alignments harvested from 30 petabytes of unassembled genomic data and developing ...

  摘要：Parasitic plants rarely attack themselves, suggesting the existence of a kin-avoidance mechanism. In the root parasitic plant Phtheirospermum japonicum, prehaustorium formation is triggered by host-secreted haustorium-inducing factors (HIFs), but it is unresponsive to its own exudates. Here we report the identification of the spontaneous prehaustorium 1 (spoh1) mutant, which forms prehaustoria without external host signals. spoh1 harbors a point mutation in the gene encoding uridine diphosphat...
• Positive affective contagion in bumble bees AI翻译

  摘要：Affective contagion, a core component of empathy, has been widely characterized in social vertebrates but its existence in any invertebrate is unknown. Using a cognitive bias paradigm we demonstrate positive affective contagion in bumble bees. After being trained on colored flowers with different reinforcements, bees that interacted with a conspecific in a positive affective state were quicker and more likely than controls to land on ambiguous colored flowers, indicating the transfer of a posi...

  摘要：Extreme drought events are predicted to increase with climate change, yet their impacts on ecosystem carbon dynamics under warming and elevated carbon dioxide (eCO2) remain unclear. In a peatland experiment with five warming treatments each under ambient carbon dioxide (aCO2) and eCO2 (+500 parts per million), a 2-month extreme drought in 2021 reduced net ecosystem productivity by 444.0 +/- 65.8 and 736.6 +/- 57.8 grams of carbon per square meter at +9 degrees C under aCO2 and eCO2, respective...
