Although previous research has found that native trees often host more arthropods, studies have not simultaneously looked across space and time to determine the consistency of tree origin on urban arthropods. We combined varied methods across spatial and temporal scales in New York City to test if native tree leaves consistently have more insect and mite interactions than long-established non-native trees, predicting stronger effect sizes for specialists (galling arthropods) than generalists (herbivory). We examined (1) congeneric species pairs, controlled for growing conditions and stoichiometry in an arboretum, (2) diverse oaks at a botanical garden, (3) community science records across Brooklyn, and (4) herbarium specimens from 1883 through present across the city. Across spatiotemporal scales, we found consistent results. Specialist interactions were striking: contemporary native trees supported numerous galling species, while only one congeneric non-native species hosted any galls. For generalists, contemporary native trees had equivalent to slightly greater herbivory. Over the last century, herbarium records showed that herbivory increased on non-native trees to nearly the level of natives, whereas native trees increased in gall abundance while non-native trees remained rarely galled. Our results demonstrate the impact of tree origin on tree-arthropod interactions in a real-world urban setting, with far fewer galls even when non-native tree species have been cultivated locally for centuries. Our findings will help city planners and property owners confidently choose native trees to promote arthropod biodiversity.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13545130/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892105","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}

In this study, we manipulated predator access on 18 exotic oak (Quercus) species grown in a common garden, spanning a gradient of phylogenetic distance to four european oaks (Q. robur, Q. petraea, Q. suber, or Q. pyrenaica). We excluded three predator guild treatments: ground-dwelling arthropod predators (hereafter ant exclusion, because the sticky-barrier method used primarily excludes ants), vertebrate predators (mainly birds), and both predator groups combined. We quantified cumulative leaf herbivory and plant chemical traits (volatile organic compounds and phenolics). Under ambient predator access, herbivory declined with increasing phylogenetic distance from native oaks (r = - 0.49, P = 0.038), consistent with previous work in this system. This relationship disappeared following ant exclusion (r = - 0.08, P = 0.76), and a phylogenetic generalized least-squares model detected a significant treatment × phylogenetic distance interaction (F = 2.96, P = 0.033) that remained robust after accounting for phylogenetic non-independence among species (phylogenetic regression slope, P = 0.001). Excluding vertebrate predators increased herbivory consistently across the phylogenetic gradient. Total VOC emissions and phenolic concentrations were unrelated to phylogenetic distance; however, multivariate VOC composition diverged with phylogenetic distance (Mantel r = 0.26, P = 0.049), unlike phenolic composition (P = 0.62). These results indicate that ant-mediated predation, not bulk chemical defences, underlies the phylogenetic herbivory pattern, highlighting predator identity as an underappreciated axis of plant-herbivore-predator interactions in novel communities.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is substantial variation in mutualist quality. How this variation in mutualist quality affects higher trophic levels, such as herbivores, is unclear, as high-quality resource mutualists could increase both leaf nutrient content, which should improve herbivore growth, but also plant chemical defenses, which are expected to negatively impact herbivores. We evaluated the effect of rhizobium strains of varying mutualist quality on the survival and development of a generalist insect herbivore, the beet armyworm (Spodoptera exigua), reared on alsike clover (Trifolium hybridum). We inoculated T. hybridum with cooperative (\"high-quality\") and less cooperative (\"low-quality\") rhizobia strains, measured plant growth, nutrients, and metabolites, and fed the leaves to S. exigua. We found that high-quality rhizobium strains significantly improved S. exigua survival, but also increased development time compared to low-quality strains. Furthermore, some developmental traits, such as pupal weight and adult wing area, increased in high-quality treatments. Inoculation with strains of varying quality impacted T. hybridum nutrition and phytochemistry, suggesting that both could mediate herbivore responses to mutualist quality. The effects of rhizobium genetic variation on herbivores exceeded the effects of N-fertilization alone: S. exigua fed leaves from uninoculated, fertilized plants had decreased survival compared to caterpillars fed leaves from high-quality partners, implying that N deposition into ecosystems may not fully replace benefits provided by rhizobia to higher trophic levels.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13545029/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892115","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}

We analyzed 10 years of weekly phenological recordings from 480 trees across 20 transects in a perhumid forest fragment at Los Tuxtlas (Mexico), characterizing the seasonal patterns, multi-scale variance structure, inter-annual consistency, and temporal covariation of five phenophases: young leaves, mature leaves, unripe fruits, ripe fruits, and flowers. All phenophases deviated significantly from uniform annual distributions (Rayleigh test, all p < 0.05), with flowers showing the highest seasonal concentration (mean vector length r = 0.52, Fourier peak April, R2 = 0.93) and mature leaves the lowest (r = 0.08). Mixed-effects variance partitioning revealed that month-within-year (seasonal) variance dominated total phenological variation across all phenophases, while between-year variance was negligible for four of five phenophases and significant only for mature leaves (18.0%). Annual phenological profiles showed moderate to high inter-annual repeatability (ICC(2,1) = 0.58-0.88), with flowers and unripe fruits exhibiting the most consistent profiles and tightest peak timing (circular SD ≤ 2.7 weeks). Young leaves and flowers showed significant positive covariation across years (mean r = 0.72, range 0.39-0.86 across all 10 years, p FDR < 0.001), with simultaneous above-average availability for 15 consecutive weeks.

Experiments now suggest that predators do not control coral reef sponges in their home habitat, shifting attention to effects of variations in sponge food supply. Comparing growth and survival of eleven of the most common and ubiquitous Caribbean coral reef sponge species on reefs in Belize and Panama differing in water column richness revealed faster sponge growth (by factors of 1.79-3.22 depending on the species) in the more picoplankton/nutrient-rich water at the Panama site. This could: a) benefit reefs by increasing positive effects of sponges, or b) harm reefs by sponges overgrowing corals. 'Sponges' is not a homogeneous category, so the balance between benefit and harm to reefs by increases in 'sponges' depends on both the species involved and environmental context. Predictions are complicated because sponge responses to increased nutrients/picoplankton are not monotonic: moderate increases boost sponge growth rates, but very dense blooms can devastate reef sponge populations. The same sponge species which grew faster in a somewhat richer water column (2 times as much picoplankton) lost nearly 2/3 of their biomass during a dense (8 times denser than normal) cyanobacteria bloom on the Belize Barrier Reef, reducing their unique positive functional roles of promoting water column clarity, symbiont habitat, food for charismatic megafauna, coral survival, and reef regeneration.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13534227/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148875605","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}

In this integrative analysis, I synthesize and reanalyze published data on three-dimensional growth in the foliose cephalolichen Lobaria pulmonaria transplanted in pristine North American forests, encompassing thallus area expansion, biomass accumulation, thallus thickening, and reproductive investment across multiple environmental gradients. Best subset regression selection and linear mixed models were applied to identify the principal internal and external factors influencing growth, specifically thallus area expansion and thickening, quantified as increases in specific thallus mass. The analyses reveal pronounced intrathalline growth heterogeneity, significant trade-offs between reproductive investment and growth, and the multifactorial influences of bark pH, elevation, light regime, and phosphorus availability. Light was often a limiting growth factor within forest interiors, whereas excessive stand openness caused chlorophyll bleaching and reduced growth. Initial phosphorus enrichment enhanced thallus thickness but did not consistently promote area or biomass expansion. Taken together, these finding highlight the habitat specialization of L. pulmonaria and the importance of bark pH, light, hydration, and reproductive investment in shaping growth dynamics. The study advances the understanding of growth strategies in L. pulmonaria and provides a foundation for predicting responses to environmental change and guiding conservation efforts.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13534230/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148875598","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}

However, environmental factors like stress or energy gradients could modify their influence. Furthermore, engineering effects include legacies that persist after the engineer's death that may interact with gradients differently than the live engineer. Here, we show that live and legacy effects of the oyster Crassostrea virginica, a reef-building ecosystem engineer, act in opposing directions across a physical energy gradient, reversing oysters' net engineering effect. When energy is low, live oysters primarily buffer erosional forces and increase habitat availability for cordgrass (Spartina alterniflora). When energy is high, legacy effects of oysters on cordgrass are negative, because high energy piles dead oyster shells onto cordgrass and smothers it. Thus, with increasing energy, net effects of engineering on cordgrass shift from positive live effects to negative legacy effects. Estuary wide, oysters have a net positive effect on cordgrass, because high energy coastlines - where negative effects predominate - are rare. Live and legacy engineering can have disparate, context-dependent effects; combined, they determine the overall effects of engineers on communities.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13524962/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851080","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}

If plants use leaf senescence as part of a competitive strategy, we expect that leaves with low competitive value would be sacrificed to supply nitrogen to leaves with high competitive value. However, when plants have multiple branches, it is unclear if plants can target leaves in shaded conditions for senescence and whether they prioritize the growth of their shaded or unshaded branches. We measured changes in leaf nitrogen in sunflowers (Helianthus annuus) grown with two symmetrical branches that were then subjected to either shaded or unshaded light conditions. We complemented the experiment with a mathematical model of leaf senescence to test whether our proposed physiological mechanisms could explain the results. When both branches were grown in low light, leaf senescence was inhibited relative to plants with both branches grown in high light. For plants with one branch in high light and one branch in low light, the senescence of older leaves was inhibited in the high-light branch, but accelerated in the low-light branch. This was associated with an increase in the growth rate of the youngest leaves in the low-light branch. Our mathematical model reproduced these results, suggesting that leaf senescence may be mediated by the carbon status of the plant. The pattern of leaf senescence and growth in this experiment was consistent with a strategy that prioritizes competing with neighbors for light rather than avoiding competition.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is largely mediated by microbes and soil invertebrates. Global decomposition studies have demonstrated that decomposition is primarily temperature-driven with rainfall playing a secondary role, although to date, all global decomposition studies have used a single substrate to measure decomposition meaning differences with substrate type may be missed. Here we explored the decomposition of wood, dung and grass along a semi-arid rainfall gradient (380-650 mm/year) at three savanna sites in north-eastern South Africa. As the three sites experience a similar temperature range, we effectively controlled for temperature allowing us to explore the effect of rainfall in isolation. We used decomposition bags - with and without termite access - and measured mass loss after set time intervals. We predicted that the absolute decomposition of all three substrates would increase along the rainfall gradient. This assumption held for dung and grass, but we found the reverse for wood. Our study highlights the importance of considering multiple substrates as decomposition patterns and dominant agents can vary. Unexpectedly low wood decomposition at our wettest site suggests that the amount of dead wood available, and therefore probability of discovery by termites, may be an important factor explaining findings from decomposition studies. Resource availability and termite discovery is a neglected subject within decomposition studies and warrants further investigation.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13525070/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851160","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}

Predator-induced hatching plasticity allows embryos to adjust hatching timing in response to predator cues, yet interspecific variation in delayed hatching has rarely been examined. Phytoseiid mites provide a useful system because delayed hatching can be induced by mechanical stimuli mimicking predator attacks, and predation risk from cannibalism and intraguild predation (IGP) in the vulnerable larval stage varies among species according to diet specialisation. We compared delayed hatching responses among four phytoseiid mite species differing in cannibalism and diet specialisation by exposing eggs to mechanical stimulation and recording hatching timing with unstimulated controls. Mechanical stimulation induced stronger delayed hatching responses in Neoseiulus californicus (odds ratio = 5.73) and Neoseiulus cucumeris (odds ratio = 7.83), a weaker response in Phytoseiulus persimilis (odds ratio = 3.11), and no detectable response in Typhlodromus bambusae (odds ratio = 0.99). The magnitude of delayed hatching corresponded to interspecific differences in cannibalism and diet specialisation, suggesting that variation in predation risk associated with intraguild interactions shapes hatching timing strategies. These findings support the hypothesis that delayed hatching is an adaptive life-history response to intraguild predation risk and suggest that interspecific variation in hatching plasticity may have important consequences for predator community dynamics and the establishment success of biological control agents.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
