In northern Yellowstone's ungulate winter range, or northern range, intensive herbivory by Rocky Mountain elk (<i>Cervus canadensis</i>) was a dominant force across the landscape during the seven decades when gray wolves (<i>Canis lupus</i>) were absent, suppressing the growth of deciduous woody plants and affecting the availability of resources and physical habitat for other species (Barmore, <span>2003</span>; Jonas, <span>1955</span>; Kay, <span>1990</span>). However, following the 1995–1996 reintroduction of wolves, thus completing the park's large carnivore guild, studies of willows (<i>Salix</i> spp.) in the northern range reported that some of them were again growing taller due to a decrease in herbivory—a trophic cascade resulting from large carnivore restoration (e.g., Baril et al., <span>2011</span>; Beyer et al., <span>2007</span>).</p><p>Hobbs et al. (<span>2024</span>), hereafter referred to as Hobbs et al., conducted research to evaluate the effects of a restored large carnivore guild on willow dynamics by studying their heights over time in northern Yellowstone riparian zones and concluded that apex predator restoration was unsuccessful in restoring riparian willow communities. This conclusion relied on a narrow and arbitrary definition of a trophic cascade and restoration success. Specifically, they indicated that since tall willows were largely lost from the northern range within two decades following apex predator loss, a similarly abrupt recovery of tall willows following apex predator restoration was necessary for evidence of a trophic cascade and willow restoration. We demonstrate, based on published research, that a trophic cascade in northern Yellowstone is reversing the effects of large predator loss to multiple taxa and food webs. Although specific historical conditions in riparian areas have not been fully replicated or restored, important ecological processes have been changed and a trajectory of ecosystem restoration is underway.</p><p>Hobbs et al. conducted their 20-year study (2001–2020) of willows growing on riparian floodplains and terraces along streams in the park's northern range.

Major bodies of ecological theory have emerged, largely independently, to address temperature and resource effects. It remains a pressing challenge to unite these ideas and determine the interactive effects of temperature and resources on ecological patterns and processes, and their consequences across ecological scales. Here, we propose a simple, physiologically motivated model capturing the interactive effects of temperature and resources (specifically, inorganic nutrients and light) on the growth of microbial ectotherms over multiple ecological scales. From this model we derive a set of key predictions. At the population level, we predict (1) interactive effects of resource limitation on thermal traits (parameters describing effects of temperature on growth), (2) consistent differences in the temperature sensitivity of auto- and heterotrophs, and (3) the existence of specific trade-offs between traits that determine the shape of thermal performance curves. At the community level, we derive predictions for (4) how limitation by nutrients and light can change the relationship between temperature and productivity. All four predictions are upheld, based on our analyses of a large compilation of laboratory data on microbial growth, as well as field experiments with marine phytoplankton communities. Collectively, our modeling framework provides a new way of thinking about the interplay between two fundamental aspects of life—temperature and resources—and how they constrain and structure ecological properties across scales. Providing links between population and community responses to simultaneous changes in abiotic factors is essential to anticipating the multifaceted effects of global change.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"95 4","pages":""},"PeriodicalIF":7.5,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145664623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molina,&nbsp;Ignasi Bartomeus","doi":"10.1002/ecm.70046","DOIUrl":"10.1002/ecm.70046","url":null,"abstract":"<p>Climate change is altering the phenology of interacting species, potentially leading to mismatches in the timing of their interactions. This may affect the delivery of key ecosystem services such as pollination. Temperature-mediated phenological variation has been widely studied at the species level, showing that increased temperatures lead to earlier activity periods for both plant flowering and pollinator emergence. However, some classic examples of tracked interacting pairs show that phenological mismatches can occur between plants and pollinators. Even though plants and pollinators are embedded in complex interaction networks, it remains unclear how phenological shifts scale up to the community level and what role biodiversity may play in buffering negative outcomes. We analyzed an 8-year time series of plant and pollinator seasonal abundances across 12 Mediterranean scrublands increasingly affected by drought and extreme temperatures, focusing on the subset of common species whose phenology could be reliably described each year. Our aim is to understand how climate change has altered plant–pollinator interactions from the species to the community level. We found that plants and pollinators have been advancing their phenologies over time at similar rates, with an average advance of 5 days per decade. Changes in rainfall and temperature patterns are key drivers of these advances. Despite the congruent shifts and no consistent change in pairwise phenological overlap, total overlap between each species and its potential partners has slightly declined over time. While more diverse communities show higher potential overlap, biodiversity is not directly buffering the reduction in interaction overlap in the studied rich communities. However, in silico experiments show that the buffering effect of biodiversity becomes apparent at lower diversity levels (i.e., fewer than 10 species). In the context of ongoing climate change, protecting diverse communities with high interaction overlap is crucial, as phenological shifts may gradually erode network structure in Mediterranean plant–pollinator systems. Sustained long-term data collection is also essential to understand the fate of most species, including those whose low abundances may conceal early signs of biodiversity loss.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"95 4","pages":""},"PeriodicalIF":7.5,"publicationDate":"2025-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145619639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Little is known about the developmental history of these <i>Sphagnum</i> patches and whether they represent incipient peatlands established in response to warming-related environmental changes. Nine peat cores were collected from nine <i>Sphagnum</i>-dominated peat patches spanning an approximately 300-km longitudinal gradient on the North Slope to determine their development and establishment history. Stratigraphically constrained cluster analysis was applied to plant macrofossil data, carbon-to-nitrogen ratios, and total organic matter measured from bulk peat to delineate developmental phases, and radiocarbon dating was used to constrain the timing of <i>Sphagnum</i> peat patch establishment. We compared these data to changes in testate amoeba community composition and amoeba-inferred water-table depth and pH in six of the peat cores. We also compared <i>Sphagnum</i> peat-patch development and establishment history to paleoclimate and local instrumental temperature records. Results indicated a predictable pattern that describes the transition from moist tussock tundra to <i>Sphagnum</i> peat. Furthermore, although <i>Sphagnum</i> has been present on the North Slope for millennia, our data suggest that <i>Sphagnum</i>-dominated peat patches constitute recent landscape features, mainly established in the 1800s and 1900s, and with rapidly increasing <i>Sphagnum</i> abundance in the past 50 years. <i>Sphagnum</i> expansion was associated with pronounced changes in testate amoeba communities, including an increase in mixotrophic taxa and species associated with densely growing <i>Sphagnum,</i> and community changes consistent with drying and increased acidity. The recent development of <i>Sphagnum</i>-dominated peat patches has been associated with warming air and soil temperatures, active layer deepening, and earlier snowmelt. <i>Sphagnum</i> expansion has also been observed in other arctic regions, and understanding the extent and growth potential of <i>Sphagnum</i> peat patches has implications for understanding and anticipating changes in carbon cycling, edaphic conditions, permafrost thermal regimes, and floristic diversity.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"95 4","pages":""},"PeriodicalIF":7.5,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145610939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
