Host interaction generalism was linked to contrasting patterns in bacterial and AMF biomass: Phylogenetic diversity in plant interactions was positively associated with AMF biomass, while numeric diversity was negatively associated with bacterial biomass in rhizosphere soils.

The Caatinga, the largest ecosystem of seasonally dry tropical forests and woodlands in South America, remains underrepresented in terms of dispersal unit data, which are often scattered across the scientific literature or remain unpublished. To address this gap, we compiled a dataset of morphophysiological data for 100 native taxa, including key information such as germination, seed water content, 1000 seed mass, fruit shape, and the geographic coordinates of 1981 seed lots. Over nine years, more than 60 t of dispersal units were harvested, representing 91% of the most dominant woody species in this ecosystem. These records stem from environmental licensing actions associated with the São Francisco River Integration Project (PISF), the Re-Habitar Ararinha Azul Project, and verified literature. This dataset, the first of its kind for the Caatinga, offers valuable potential for research on forest dynamics, dispersal, germination, conservation, and ecological restoration in the Brazilian semiarid region. We hope this data paper provides reliable information on local flora distribution, dispersal syndromes, and morphological descriptions, while also suggesting methods for overcoming seed dormancy in the Caatinga.

By integrating datasets over four consecutive years from an experiment with enrichments of soil acidification and N and P in a semiarid grassland on the Mongolian Plateau, we explored the effects of environmental changes on community attributes (species richness, asynchrony, and compositional temporal stability) of plants and soil biota (bacteria, fungi, and nematodes) and their associations with EMF stability.

Soil acidification had a more significant effect on the community attributes of plants and soil biota, as well as on the components of EMF stability, than nutrient enrichment. Soil acidification decreased both the mean and stability of EMF, while N enrichment increased the mean of EMF. P did not have a significant effect on the components of EMF stability, but N and P showed positive interactive effects on the mean and stability of EMF. We also found that plant and soil biota richness had a positive effect on EMF, while plant asynchrony and soil biota compositional stability determined EMF stability.

Of all the plastics ever produced, 79% is still with us, as they remain in landfills or in the natural environment (Geyer et al., &lt;span&gt;2017&lt;/span&gt;). The disruption driven by our collective human activities on Earth may result in a new geological epoch: the Anthropocene (Crutzen &amp; Stoermer, &lt;span&gt;2021&lt;/span&gt;). This contemporary period in the geological history of planet Earth is defined by the impact humans have on our natural world and is already a firmly established term in environmental sciences. Plastic may be used as a global marker for the Anthropocene, which allows plastic items to be used as “index fossils” to date with accuracy sediment layers within the Anthropocene epoch (Corcoran et al., &lt;span&gt;2017&lt;/span&gt;), especially using the expiration date printed or stamped on food packaging or perishable products in general as a back-dating tool (Cau et al., &lt;span&gt;2019&lt;/span&gt;; Hoffmann &amp; Reicherter, &lt;span&gt;2014&lt;/span&gt;). Single-use plastic food and drink packages now dominate plastic production (Geyer et al., &lt;span&gt;2017&lt;/span&gt;; Williams &amp; Rangel-Buitrago, &lt;span&gt;2022&lt;/span&gt;) and consequently are the categories of litter most often encountered in Dutch freshwater systems (Boonstra &amp; de Winter, &lt;span&gt;2019&lt;/span&gt;, p. 19). As these types of packaging are so widely present as litter, the material has also been adopted by birds to build their nests. Building with artificial materials is widespread (Jagiello et al., &lt;span&gt;2023&lt;/span&gt;), and a broad range of items may become part of a bird nest, even materials that are meant to deter birds (Hiemstra et al., &lt;span&gt;2023a&lt;/span&gt;). Food and drink packages have been documented as nest material in a wide variety of birds (Appendix S1: Section S1), one of which is the common coot (&lt;i&gt;Fulica atra&lt;/i&gt;; Hiemstra, Gravendeel, et al., &lt;span&gt;2021&lt;/span&gt;). An urban population of the latter species in Leiden, The Netherlands, proved to be one of the first bird populations for which &lt;i&gt;all&lt;/i&gt; nests contained plastic (Hiemstra, Gravendeel, et al., &lt;span&gt;2021&lt;/span&gt;). The common coot is a wetland bird that in The Netherlands originally built its nests of plant materials which rapidly decay, so coots normally construct a new nest every year (Gadsby, &lt;span&gt;1978&lt;/span&gt;; Jedlikowski &amp; Polak, &lt;span&gt;2019&lt;/span&gt;). However, as plastics and other artificial, more durable materials are used for nest construction, new behavior, namely, the reuse of nests from previous years, may appear. This, in turn, may create a history of multiple years of nest use, reuse, and reconstruction to be studied using the stratigraphy of dateable plastic debris in the nest.&lt;/p&gt;&lt;p&gt;To document such a history of reuse, we collected common coot (&lt;i&gt;F. atra&lt;/i&gt;) nests in the city center of Amsterdam, The Netherlands, on 22 September 2021 (after the end of the breeding season, when all nests were abandoned).

Assessing species viability under climate warming requires demographic studies integrating vital rate responses to long-term warming throughout species' life cycles. However, studies of this nature are rare. Our integral projection models (IPMs), parameterized with demographic data, show differing responses of two functionally similar co-occurring species, <i>Elymus nutans</i> Griseb. and <i>Helictotrichon tibeticum</i> (Roshev.) Holub, to 10 years of in situ active warming by 2°C. Our IPMs estimated that the life expectancy is higher in <i>H. tibeticum</i> (6.7 years) than that in <i>E. nutans</i> (4.5 years) under ambient conditions, and the difference is larger under warmed conditions. We found that while warming decreased individual-level growth in both species, <i>H. tibeticum</i>, which has a longer life expectancy, compensated with increased survival, and thereby increased projected population-level growth under warming. Contrastingly, <i>E. nutans</i>, which has a shorter life expectancy, is projected to have decreased population-level performance. Furthermore, our elasticity analyses show that survival is the most important vital rate for population viability in both species under both ambient and warmed conditions. Moreover, our retrospective life table response experiment (LTRE) analysis reveals that the contrasting fates of the two species under warming mainly arise from the different responses of adult survival, which is significantly promoted in <i>H. tibeticum</i> but slightly reduced in <i>E. nutans</i>. Individual shrinkage occurred 1.6 fold more frequently under warming than ambient conditions for both species and made considerable negative contributions to their population growth rates in warmed plots. However, such negative effects are offset in <i>H. tibeticum</i> (but not <i>E. nutans</i>) by the positive contribution to population growth rate of the associated increased survival. Our results illustrate that the responses to climate warming may vary considerably between similar co-occurring species, and species with a demographically compensatory strategy may avoid population collapse. Furthermore, our study demonstrates the potential of using life-history traits to predict species' viability when facing warming, so as to inform biodiversity conservation under climate change.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"106 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475450","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 also requires knowledge about the abundance and diversity of multispecies assemblages. Variation in the distribution and composition of kelp forests, one of the most productive marine coastal habitats globally, can have major influences on reef fishes—a group of ecologically and socioeconomically important species. In the face of widespread and escalating loss of kelp forests, quantification of these effects is urgently needed to assess and project cascading impacts on biodiversity. Here, we evaluate relationships between kelp forests and associated reef fish populations using a global meta-analysis of experimental kelp removals and comparative surveys of kelp and adjacent non-kelp habitats. These analyses show that kelp forests increase the abundance of reef fishes, though the significance of this effect varied depending on the structural complexity of kelp forests. In experimental studies, kelp forests have a significant positive effect on fish species richness, revealing that kelp act as true foundation species by supporting the diversity of associated multispecies assemblages. Importantly, regardless of kelp forest morphology and type of study (observational or experimental studies), kelp forests enhance the recruitment of early life history stages suggesting they are nursery habitats for many reef fish taxa. Lastly, kelp forests differentially affected species with different functional traits; small body size fishes from low trophic levels (e.g., herbivore and detritivores, micropredators, and mesopredators) and large body size fish from higher trophic level (e.g., piscivores, general carnivores) were both facilitated by kelp forests.

Although incorporating home range formation with a theoretical basis of animal movement into SCRs can improve the prediction of animal space use in a heterogeneous landscape, this approach is challenging owing to the sparseness of recapture events. In this study, we developed an advection–diffusion capture–recapture model (ADCR), which is an extension of SCRs incorporating home range formation with advection–diffusion formalism, providing a new framework to estimate population density and landscape permeability. we tested the unbiasedness of the estimator using simulated capture–recapture data generated by a step selection function. We also compared the accuracy of population density estimates and home range shapes with those from SCR incorporating the least-cost path and basic SCR. In addition, ADCR was applied to a real dataset of Asiatic black bear (<i>Ursus thibetanus</i>) in Japan to demonstrate the capacity of the ADCR to detect geographical barriers that constrain animal movements. Population density and permeability of ADCR were substantially unbiased for simulated datasets. ADCR could detect environmental signals on connectivity more sensitively and could estimate population density, home range shapes, and size variations better than the existing models. For the application to the bear dataset, ADCR could detect the effect of water bodies as a barrier to movement, which is consistent with previous studies, whereas estimates by SCR with the least-cost path were difficult to interpret. ADCR provides unique opportunities to elucidate both individual- and population-level ecological processes from capture–recapture data. By offering a formal link with step selection functions to estimate animal movement, it is suitable for simultaneously modeling capture–recapture data and animal movement data.
