The intertidal sea anemone, <i>Anthopleura elegantissima</i>, engages in a nutritional symbiosis with microalgae similar to tropical coral, but withstands more intense environmental fluctuations during tidal inundations. In this study, we compare baseline symbiotic traits and their sensitivity to thermal stress within and among anemone aggregations across the intertidal using a laboratory-based tank experiment to better understand how fixed genotypic and plastic environmental effects contribute to the successful maintenance of this symbiosis in extreme habitats. High intertidal anemones had lower baseline symbiont-to-host cell ratios under control conditions, but their symbionts had higher baseline photosynthetic efficiency compared to low intertidal anemone symbionts. Symbiont communities were identical across all samples, suggesting that shifts in symbiont density and photosynthetic performance could be an acclimatory mechanism to maintain symbiosis in different environments. Despite lower baseline symbiont-to-host cell ratios, high intertidal anemones maintained greater symbiont-to-host cell ratios under heat stress compared with low intertidal anemones, suggesting greater thermal tolerance of high intertidal holobionts. However, the thermal tolerance of clonal anemones acclimatized to different zones was not explained by tidal height alone, indicating additional environmental variables contribute to physiological differences. Host genotype significantly influenced anemone weight, but only explained a minor proportion of variation among symbiotic traits and their response to thermal stress, further implicating environmental history as the primary driver of holobiont tolerance. These results indicate that this symbiosis is highly plastic and may be able to acclimatize to climate change over ecological timescales, defying the convention that symbiotic organisms are more susceptible to environmental stress.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"105 9","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.4388","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141794369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Competition for wintering and breeding sites has been suggested to be an ultimate factor, and several competitor-based hypotheses have been proposed to explain this pattern. If wintering sites close to the breeding sites are favored, competitive exclusion could force subdominant individuals to winter further away. Competitive exclusion could be mediated either through body size or by prior occupancy. The alternative “spring predictability” hypothesis assumes competition for sufficiently close wintering areas, allowing the birds to use autocorrelated weather cues to optimally time spring migration departure. To test predictions and assumptions of these hypotheses, we combined morphometrics, migration, and weather data from four populations of common ringed plover breeding along a latitudinal (56–68° N) and climatic gradient (temperate to Arctic). Critical for our evaluation was that two populations were breeding on the same latitude in subarctic Sweden with the same distance to the closest potential wintering site, but differed in breeding phenology, and wintered in West Africa and Europe, respectively. Thus, while breeding on the same latitude, their winter distribution overlapped with that of an Arctic and temperate population. Body size was largest within the temperate population, but there was no size difference between the two subarctic populations. Populations wintering in Europe arrived there before populations wintering in Africa. The largest variation in the arrival of meteorological spring occurred at the temperate breeding site, while there was almost no difference among the other sites. In general, temperatures at the northernmost wintering area correlated well with each breeding site prior to breeding site-specific spring arrival. Based on these observations, we conclude that competitive exclusion through body-size-related dominance cannot explain leapfrog migration. Furthermore, the assumptions on which the “spring predictability” hypothesis is based did not match the observed wintering ranges either. However, we could not reject the hypothesis that competitive exclusion mediated by prior occupancy in the wintering area could lead to leapfrog migration, and therefore, this hypothesis should be retained as working hypothesis for further work.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"105 9","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.4379","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141763477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The mechanisms underlying the response of herbaceous communities to such drier environments should be investigated to identify the resilience thresholds of Mediterranean rangelands. A 5-year experiment was conducted in deep and shallow soil rangelands of southern France. A rainout shelter for 75 days in summer imposed drier and warmer conditions. Total soil water content was measured monthly to model available daily soil water. Aboveground net primary production (ANPP), forage quality, and the proportion of graminoids in ANPP were measured in spring and autumn. Plant senescence and plant cover were assessed in summer and spring, respectively. The experimental years were among the driest ever recorded at the site. Therefore, manipulated summer droughts were drier than long-term ambient conditions. Interactions between treatment, community type, and experimental year were found for most variables. In shallow soil communities, spring plant cover decreased markedly with time. This legacy effect, driven by summer plant mortality and the loss of perennial graminoids, led to an abrupt loss of resilience when the extreme water stress index exceeded 37 mm 10 day⁻¹, characterized by a reduction of spring plant cover below 50% and a decreased ANPP in rainy years. Conversely, the ANPP of deep soil communities remained unaffected by increased summer drought, although the presence of graminoids increased and forage nutritive value decreased. This study highlights the role of the soil water reserve of Mediterranean plant communities in modulating ecosystem responses to chronically intensified summer drought. Communities on deep soils were resilient, but communities on shallow soils showed a progressive, rapid, and intense degradation associated with a loss of resilience capacity. Notably, indexes of extreme stress were a better indicator of tipping points than indexes of integrated annual stress. Considering the role of soil water availability in other herbaceous ecosystems should improve the ability to predict the resilience of plant communities under climate change.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"105 9","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.4383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141763475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Using Bayesian hierarchical models, we took advantage of 10-year seedling monitoring data that were collected annually in every dry and rainy season in a seasonal tropical forest. We quantified the interspecific variation in the strength of CNDD and its temporal variation. We also examined potential correlates of this interspecific and temporal variation, including species functional traits (such as drought-tolerant traits, defense-related traits, and recourse acquisition traits) and species abundances. In the dry season, we found a negative relationship between the density of neighboring conspecific seedlings on seedling survival, while in the rainy season, there was a negative relationship between the density of neighboring conspecific adults on seedling survival. In addition, we found that interspecific variation in CNDD was related to drought-tolerant traits in the dry season but not in the rainy season. Across years, we found that drought-intolerant species suffer less CNDD during the dry seasons that have higher rainfall, whereas drought-tolerant species suffer less CNDD when the dry season has lower rainfall. We also found that rare species suffered stronger CNDD in the dry season.

The nutrient balancing hypothesis suggests that, when given the opportunity, animals select foods to achieve a particular target nutrient balance, and that balancing occurs between meals and between days. For wild ruminants who inhabit landscapes dominated by human land use, nutritionally imbalanced diets can result from ingesting agricultural crops rich in starch and sugar (nonstructural carbohydrates [NCs]), which can be provided to them by people as supplementary feeds. Here, we test the nutrient balancing hypothesis by assessing potential effects that the ingestion of such crops by <i>Alces alces</i> (moose) may have on forage intake. We predicted that moose compensate for an imbalanced intake of excess NC by selecting tree forage with macro-nutritional content better suited for their rumen microbiome during wintertime. We applied DNA metabarcoding to identify plants in fecal and rumen content from the same moose during winter in Sweden. We found that the concentration of NC-rich crops in feces predicted the presence of <i>Picea abies</i> (Norway spruce) in rumen samples. The finding is consistent with the prediction that moose use tree forage as a nutritionally complementary resource to balance their intake of NC-rich foods, and that they ingested <i>P. abies</i> in particular (normally a forage rarely eaten by moose) because it was the most readily available tree.

Longevity has been associated with a variety of other life history and morphological traits such as brain and body size (Lindstedt &amp; Calder, &lt;span&gt;1981&lt;/span&gt;; Stearns, &lt;span&gt;1992&lt;/span&gt;), energy metabolism (Furness &amp; Speakman, &lt;span&gt;2008&lt;/span&gt;; White &amp; Seymour, &lt;span&gt;2004&lt;/span&gt;), hibernation strategy (Turbill et al., &lt;span&gt;2011&lt;/span&gt;; Wilkinson &amp; South, &lt;span&gt;2002&lt;/span&gt;), and antioxidant capacity (Vágási et al., &lt;span&gt;2019&lt;/span&gt;). Meaningful longevity data, however, necessitate studies of marked individuals over extended periods, a requirement that can be challenging for long-lived vertebrate species. Long-term mark-recapture efforts provide some of the best opportunities for obtaining longevity estimates from free-living populations of animals. For example, among birds, continent-wide banding programs in North America (i.e., U.S.G.S. Bird Banding Laboratory [BBL]: https://www.pwrc.usgs.gov/bbl/longevity/longevity_main.cfm) and Europe (i.e., EURING: https://euring.org/data-and-codes/longevity-list) comprise decades of individual-based monitoring that have yielded longevity estimates for many temperate-zone species. By contrast, longevity data from tropical birds are few and restricted in temporal scope due to the logistical and financial challenges of maintaining long-term monitoring programs in the tropics (Collen et al., &lt;span&gt;2008&lt;/span&gt;; Proença et al., &lt;span&gt;2017&lt;/span&gt;). As of 2023, fewer than 250 longevity records of Neotropical landbirds are available in the published literature (reviewed in Scholer et al., &lt;span&gt;2018&lt;/span&gt;), and only two studies spanned ≥20 years (Arendt, &lt;span&gt;2006&lt;/span&gt;; Woodworth et al., &lt;span&gt;1999&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;How long do Neotropical forest landbirds actually live? To address this question, we used a 45-year (1977–2022) mark-recapture dataset from central Panama—one of the longest of its kind in the Neotropics—to derive longevity records for 47 species. We sampled birds on the 100-ha Limbo Plot on Pipeline Road in the 22,000-ha Soberanía National Park (9.15° N, 79.73° W). The Limbo Plot is classified as tropical lowland moist forest and has been the focus of numerous previous studies of tropical bird ecology (e.g., Brawn et al., &lt;span&gt;2017&lt;/span&gt;; Karr, &lt;span&gt;1976&lt;/span&gt;; Karr &amp; Freemark, &lt;span&gt;1983&lt;/span&gt;; Pollock et al., &lt;span&gt;2020&lt;/span&gt;, &lt;span&gt;2022&lt;/span&gt;; Tarwater et al., &lt;span&gt;2011&lt;/span&gt;; see Robinson et al., &lt;span&gt;2000&lt;/span&gt; for a more detailed discussion of the Limbo Plot). Netting and banding protocols are described in detail in Pollock et al. (&lt;span&gt;2022&lt;/span&gt;). Briefly, we mist-netted and banded birds twice per year (dry and wet season) at two 2-ha sites em","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"105 9","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.4386","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141763479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
