Environmental conditions and wood decay may influence the beta diversity of saproxylic beetles, potentially affecting the woodpecker's capacity to distinguish suitable foraging substrates. We assessed the patterns of beta diversity of saproxylic beetles in live trees used and not used by Magellanic woodpeckers for foraging in Patagonian temperate forests. The additive and interactive effects of wood decay and environmental conditions on beta diversity components (total diversity, species turnover, and nestedness) across different beetle guilds (all species, predators, mycophages, and wood borers) were tested. The composition of all beetle species and wood borers in foraging trees was taxonomically distinct from those found in control trees. As the wood decay gradient increased between the foraging and control trees, the nestedness of predators and mycophages also increased. The same pattern was observed for the turnover of wood borer species. Beta diversity exhibited a positive association with continuous canopy cover; however, environmental variables modulated the effects of wood decay. Increased temperatures weakened the positive responses of wood-borer species turnover and predator nestedness to wood decay. However, the impact of wood decay on the nestedness of predators was less pronounced in certain unsuitable conditions. Although total beta diversity increased as the habitat became more suitable for beetles and woodpeckers, rising temperatures in this region may cause woodpeckers to select live trees with prey communities that are less diverse than expected.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148956343","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}

On temperate reefs worldwide, herbivory by grazing macro-invertebrates can cause extensive overgrazing of kelp beds when grazers reach hyperabundance. Rising to local dominance, typically it is the grazing activity of a single species amongst others that is responsible for overgrazed 'barrens'. However, the potential for subordinate grazing species to impact kelp beds is less understood and often overlooked. Here we observe apparent 'barren' patches within kelp beds associated with local hyperabundance of a subordinate grazer, the turbinid periwinkle Lunella undulata, in eastern Tasmania. We demonstrate capacity for this periwinkle to overgraze by deploying a caging experiment on a 'peri-barren' patch, involving inclusion and exclusion treatments, plus cage and background control plots. Fleshy macroalgae proliferated in cages excluding periwinkles, reaching mean percentage cover of 47 ± 8% SE by end of the 117-day experiment, which was 5-fold, 6-fold, and 10-fold higher than in partially caged plots, open plots, and periwinkle inclusion cages, respectively. Indicating cascading effects of harvesting, legal-sized periwinkles were commercially harvested from the peri-barren during the study, leading to algal recovery across all treatments except for periwinkle inclusion cages where overgrazing persisted. Kelp bed recovery ensued as periwinkle biomass declined, while cover of fleshy algae increased over ~ 16 months. Reflecting the ongoing trophic and climate cascades in eastern Tasmania, we hypothesise that increased harvesting of the now dominant grazer, the range-extending urchin Centrostephanus rodgersii, has enabled localised competitive release of the subordinate periwinkle grazer.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13547173/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148900833","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}

Here we provide a conceptual underpinning for seaweed trait-based ecology by establishing relationships between traits and performance. We conducted a field experiment to determine if intra- and interspecific trait variation predicts variation in growth rate of three morphologically distinct species of tropical seaweed. We measured two traits for all species and three traits for the most 'plant-like' (exhibiting differentiated structures that resemble leaves, branches, and stems) species. These traits were either commonly used in previous seaweed studies or are analogs to traits commonly used for vascular plants. We hypothesized there would be positive relationships between growth and the nutrient acquisition trait and a negative relationship between growth and the herbivory and disturbance resistance trait. Across all species, we found significant relationships for both traits, with the resource acquisition trait (thallus surface area to thallus volume ratio) related positively and the resistance trait (thallus dry weight to thallus wet weight ratio) related negatively to growth. When the most 'plant-like' species was analyzed individually, we found all three resource allocation traits (blade wet weight to thallus wet weight ratio, blade volume to thallus volume ratio, and blade surface area to thallus surface area ratio) related positively to growth. To the best of our knowledge, we are the first to empirically link traits of tropical seaweed individuals directly to their performance, thereby identifying functional traits that can be used as proxies for the ecosystem function of productivity.","PeriodicalId":19473,"journal":{"name":"Oecologia","volume":"208 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148900840","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}

We determined propolis mass and wax content, used a generalised linear model to analyse the relationship between colour and wax content, and principal component analysis with generalised linear mixed models to analyse the effect of surrounding land cover on propolis composition. Colour analysis indicated that colour and wax were strongly correlated. Land cover analysis indicated that hives in proximity to larger proportions of arable land and managed grasslands, with greater floral abundance, had increased wax content, compared to hives in proximity to broadleaf woodland, suburban and urban areas with more trees and less grasslands, which tended to have lowered wax content.

Host tissue nutrient stoichiometry may elucidate these effects by indicating nutrient availability within a host's environment and/or mediating these effects on parasites. We assessed these possibilities by manipulating nutrient availability in 11 experimental ponds stocked with piscivorous largemouth bass for 3 months and quantifying the role of a digestive tissue's stoichiometry in mediating the relationship between basal nutrient availability, the abundance of both fish and invertebrate consumers (including potential intermediate hosts), and the abundance of the trematode parasite, Crepidistomum spp., in this tissue. Fertilization increased the total phosphorus (P) and decreased the carbon (C):P and nitrogen (N):P ratios in the water column and fine particulate organic matter of ponds. While we did not detect effects of fertilization on intermediate trophic levels, N:P ratios in the bass digestive tissue were inversely related to both total water column P levels and the abundance of Crepidistomum spp. in these tissues. Overall, the nutrient ratios of a key tissue involved in predator digestion mirrored fertilization-induced shifts in basal nutrient availability and explained more variation in the abundance of a trophically transmitted parasite than any other variable we quantified. Whether tissue nutrient ratios directly influenced the abundance of this parasite or simply reflected shifts in the ecosystem that mediated parasite abundance remains unclear. Regardless, digestive tissue nutrient stoichiometry appears to provide an informative link between basal nutrient availability and parasite abundance in these tissues.","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/PMC13545112/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892088","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}

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).

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}

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).
