Title: Novel physiological data needed for progress in global change ecology Authors: Herrando-Pérez, S; Vieites, D; BASTOS ARAUJO, MIGUEL Abstract: Studies examining the underlying causes of the distributions of species and their future trajectories under climate change have benefitted from the accumulation of measurements of thermal tolerance across the tree of life. However, gaps in the global coverage of heat-tolerance data for ectotherms persist on four critical fronts. First, most large-scale analyses treat heat tolerance as a fixed species trait despite that population-level variation can equal or exceed cross-species variation. Second, terrestrial non-arthropod invertebrates and aquatic ectotherms other than bony fish have been poorly sampled, particularly in boreal and tropical regions, the Indian Ocean and the mesopelagic-deep ocean. Third, the study of climate impacts on the heat tolerance of terrestrial ectotherms has often neglected the interaction of environmental temperatures with water availability. And fourth, the mechanisms driving the dependence of heat tolerance on oxygen supply-demand remain largely unknown. We contend that filling those data and knowledge gaps requires novel strategies for the ecophysiological sampling of the range of understudied populations and species that occupy the length of climatic gradients globally. Such developments are essential for comprehensively predicting species responses to climate change across aquatic and terrestrial biomes.

Title: Natural forest regeneration is projected to reduce local temperatures Authors: Alibakhshi, S; Cook-Patton, S; Davin, E; Maeda, E; BASTOS ARAUJO, MIGUEL; Heinlein, D; Heiskanen, J; Pellikka, P; Crowther, T Abstract: Forest regeneration is a crucial strategy for mitigating and adapting to global warming. Yet its precise impact on local climate remains uncertain, a factor that complicates decision-making when it comes to prioritizing investments. Here, we developed global maps illustrating how natural forest regeneration influences key local climate drivers—land surface temperature (LST), albedo, and evapotranspiration—using models fitted at a 1-km spatial resolution with a random forest classifier. We found that natural forest regeneration can alter annual mean LST by 0.01 °C, −0.59 °C, −0.50 °C, and −2.03 °C in Boreal, Mediterranean, Temperate, and Tropical regions, respectively. These variations underscore the region-specific effects of forest regeneration. Importantly, natural forest regeneration reduces LST across 64% of 1 billion hectares and 75% of 148 million hectares of potentially restorable land under different scenarios. These findings improve understanding of how forest regeneration can help regulate local climate, supporting climate adaptation efforts.

Title: Trophic convergence of marine vertebrate communities Worldwide. Authors: González-Trujillo, JD; Assis, J; Serrão, E; Costello, M; Fragkopoulou, E; Mendoza, M; BASTOS ARAÚJO, MIGUEL Abstract: Biogeographic regions arise due to constraints on species ranges, fostering lineage divergence as a result. Yet, convergent evolution means that evolutionary distinct lineages can share similar characteristics when subjected to similar environmental conditions. The ecological convergence of distinct regions has been demonstrated in terrestrial communities, but it remains uncertain if marine systems exhibit similar patterns, given the greater ease of dispersal in the ocean. Using information on the dietary preferences of marine vertebrates, we develop an ocean regionalization that groups regions with similar trophic communities, describing how species are organized into trophic guilds and how guilds overlap with one another. Six types of trophic communities emerge globally, largely explained by temperature, productivity, and depth. Regions with analogous environments support similar numbers of species with analogous feeding strategies, even if the species do not share the same evolutionary origins. These findings support the notion that independently evolving sets of marine species can converge into functionally analogous trophic communities when exposed to similar environmental conditions. They also provide a benchmark for studying the functional consequences of global environmental change.

Title: One Health Living Lab: A Collaborative and Novel Approach to Zoonotic Public Health Challenges in Portugal Authors: Lavrador, Catarina Editors: Sage Abstract: Portugal faces challenges in implementing the One Health approach for zoonotic disease. To foster integrated solutions, a “One Health Living Lab” initiative engaged diverse stakeholders, focusing on junior professionals (ie, veterinary students, public health residents, and environmental health technicians). For 2 months, multidisciplinary teams addressed Avian influ- enza H5N1 in cats, Mycobacterium caprae, Streptococcus suis, Crimean–Congo hemorrhagic fever (CCHF) through research, stakeholder engagement and solution codesign. Key outcomes included establishing a feline HPAI sentinel network, confirm- ing S suis occupational risks, developing a timely CCHF preparedness exercise and identifying potential M caprae underdiag- nosis. The living lab successfully fostered collaboration and generated practical, bottom-up initiatives. While highlighting persistent systemic barriers like data sharing, the model demonstrates a promising approach for engaging future professionals and strengthening Portugal’s health security against zoonotic threats, ensuring sustained support and integration
