Species in this group have diversified widely in multiple aspects of their biology such as predator avoidance and parental care strategies, reproductive ecology, chemical ecology, and elevational range. This diversification has been marked by dozens of historical dispersal events between the Northern Andes and their adjacent lowland forests (Amazonia, Chocó, Interandean valleys), as well as substantial in situ diversification in montane areas (Andes, Guyana Shield). Among the most striking events of montane dispersal and diversification is the genus <jats:italic>Andinobates</jats:italic> which appears to have colonized the Andes from the Chocoan lowlands in Northern South America in the late Miocene, and subsequently undergone a striking diversification both in terms of lineages and phenotypes (e.g. coloration), as well as elevational and ecological niches. Despite their clear potential as a system to understand the role of mountains in biological diversification, <jats:italic>Andinobates</jats:italic> have historically received little to no attention from biologists. In fact, most species in the genus were only described in the past 15 years. Here, we present a mtDNA dataset composed of 417 sequences at three loci for 202 individuals of most known species of <jats:italic>Andinobates</jats:italic> , including potentially undescribed ones. This dataset expands the available genetic data for this genus by an order of magnitude in terms of individuals and geographic localities. Although limited in the extent to which it can be used for population genetic inferences, mtDNA remains a powerful means by which initial hypotheses can be generated in molecular ecology and biogegoraphy, among other fields. We anticipate this dataset will ignite the generation of new research projects focused on <jats:italic>Andinobates</jats:italic> , propelling this group as a model system to shed light on the processes through which topography drives diversification.

Despite its rich mammal fauna and ecological importance, information on its diversity remains limited. This study compiles camera-trap records obtained between 2010 and 2024 to document the composition and structure of wild mammal assemblages in the region. Camera traps are an effective method for detecting a wide variety of species over large areas. The datasets obtained using this technique allow us to describe patterns and monitor the occupancy, abundance, and richness of wildlife, providing essential information for conservation in regions undergoing rapid habitat loss and fragmentation. We present a dataset of camera-trap surveys of wild mammals (&gt;1 kg) in the Colombian Caribbean. We compiled information from 635 sampling stations, collected between 2010 and 2024, resulting in 17,273 records and 3108 occurrences of 41 species belonging to 35 genera, 22 families, and nine orders. Most of the records (64.60%) come from unpublished sources, supplemented with data from online databases, scientific articles, theses, and technical reports. When available, we included information on the brand and model of the cameras and the use of bait, variables relevant to detection, was included. Carnivora was the most diverse order (16 species), followed by Rodentia (6), with Dasyprocta punctata, Didelphis marsupialis, and Cuniculus paca as the most recorded species, based on the total number of camera-trap records. Dasyprocta punctata accounted for 25.43% of all records, while Didelphis marsupialis and Cuniculus paca contributed 11.54% and 8.13%, respectively, together representing 45.11% of the entire dataset. In terms of biomass, herbivores dominated (58.05%), followed by mesocarnivores (23.07%) and large carnivores (9.70%), while omnivores contributed the smallest proportion (2.01%). Of the species recorded, 21.95% are classified in threatened categories according to the IUCN Red List, specifically Vulnerable (VU), Endangered (EN), and Critically Endangered (CR). The sampling covered a variety of environmental conditions, with greater richness in tropical dry forest, heterogeneous agricultural areas, and scrubland. This dataset can be used for studies of occupancy, relative abundance, species richness, daily activity patterns, and interspecific interactions, as well as for analysis with environmental covariates such as human footprint or landscape metrics.

Most studies suggest that niche differences (complementarity) play a significant role in shaping these effects. As most plant species require mutualistic mycorrhizal fungi to access limiting nutrients, recent evidence suggests that these mutualisms may mediate the complementarity detected in plant studies. Yet, until now, previous studies have focused primarily on the role of mycorrhizal <i>presence</i> in altering these relationships, but no studies have examined the combined effects of plant and mycorrhizal diversity in shaping productivity. Here, we use a mesocosm experimental system to manipulate ericoid mycorrhizal richness (ranging from one to seven fungal isolates) and plant richness (ranging from one to eight plant species) to assess how plant and fungal diversity interact to influence plant productivity. We find clear support for the positive effect of plant diversity on productivity, but this effect only emerged at higher levels of fungal diversity. Within plant monocultures, we found that increasing fungal diversity reduced plant productivity, consistent with antagonism between symbionts limiting plant productivity. Moreover, we found that although most species follow community-level patterns, plant species vary in their response to changing plant and fungal diversity. These results suggest that plant productivity within the ericoid mycorrhizal system is impacted by both plant and fungal diversity, with implications for the use of ericoid mycorrhizal fungi in both agriculture and restoration.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 9","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70488","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148915633","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}

Because ecologists remain keen to determine when these risk effects matter, there is a need to know how much of this literature has also evaluated the context-dependence of risk effects. Such knowledge would identify both understudied research directions and richly investigated areas whose synthesis could advance general understanding of predation risk effects. As a guide for ecologists, we reviewed publications from 1990 to 2021 that experimentally manipulated both predation risk (presence/absence of risk) and another aspect of biotic or abiotic condition (context). We classified each experiment according to a common scheme: the manipulated context was assigned to a Focus (predator, prey, resource, or environment) and Category (community, population, or individual for biotic contexts; temperature, water, habitat, or anthropogenic disturbance for abiotic contexts). A finer categorization of Specific Context (e.g., predator identity, resource abundance) was assigned within each Focus and Category. We also identified the System (marine, freshwater, terrestrial) and Venue (laboratory or field) of each experiment. We classified 433 manipulations (339 publications) falling within 49 different Specific Contexts. Many experiments (63%) manipulated aspects of the predator and/or prey Foci, independently and factorially. Additionally, several Specific Contexts have many published papers and could be suitable for synthesis, including predator and prey identity, predator diversity, prey and resource abundance, habitat structure, and temperature. Meanwhile, manipulations of resources of the prey are relatively lacking. Because most experiments (51%) featured freshwater systems, more marine and terrestrial experiments are needed. Regardless, an imbalance between laboratory (69%) and field (31%) experiments highlights the need for more field investigations. We discuss potential contributors to biases in the literature and consider how understudied contexts should be prioritized. Consequently, our review undergirds future work on the context-dependency of predation risk effects. As many biotic and abiotic contexts are impacted by anthropogenic activities, optimizing the integration of experimental approaches with other research efforts is crucial to furthering the development and application of predation risk theory.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 9","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70493","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148914765","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}

Rare species are predicted to be more susceptible to perturbations, but extreme drought may also disproportionately reduce common species that are well adapted to modal environmental conditions. Resolving these contrasting effects is key to predicting species reordering in response to extreme drought. We explored how species drought responses varied by their spatial and temporal rarity, defined by their local abundances relative to co-occurring species, at six sites across a gradient of mean annual precipitation (MAP) in the Central USA. We found that in general, both spatially sparse and temporally intermittent species increased during and after drought, while common and persistent species declined. Responses were similar at four of the six sites across a gradient of MAP, but did not align with the precipitation gradient as expected. Instead, patterns depended on the characteristics of common species, where rarity was not related to drought responses at sites with many common, early-season, C₃ annual grasses that likely avoided the effects of the summer drought. Finally, the increase in rare species persisted for 4 years after the experimental drought was lifted, suggesting that this extreme drought resulted in lasting shifts to community composition.

To elucidate these spatiotemporal interactions, we investigated the coupled dynamics of two dominant insect–host systems—spruce budworm (SBW) associated with late-successional fir and spruce, and forest tent caterpillar (FTC) associated with early-successional aspen. We assess whether asynchronous outbreak patterns shift over time and whether those shifts are consistent with forest compositional change. Using tree-ring data from mixedwood sites across a 20,000-km² hemiboreal landscape at the United States–Canada border, we reconstructed outbreak histories (1928–2005) and applied multi-scaled analyses guided by resilience theory. We analyzed outbreak dynamics across a continuous range of temporal resolutions, summarizing patterns into short (years), intermediate (decade), and long (multi-decade) windows to evaluate spatial persistence and cross-species correlations, and examined whether patterns over the longest windows align with contemporary forest composition. SBW and FTC cycled independently over short windows, but cross-correlations became increasingly negative as windows lengthened to multi-decadal scales, consistent with compositional feedbacks. Spatial persistence within species shifted from positive over short windows to strongly negative over long windows, where outbreak centers reciprocally inverted between early and contemporary periods—a “trading spaces” dynamic indicative of metastability. These patterns show that insect outbreaks are not passive responses but feedback-driven agents interacting with anthropogenic legacies that accelerate compositional change. Our findings highlight how cross-scale feedbacks involving slow and fast regulatory processes shape disturbance regimes, thus supporting resilience theory and the concept of dynamic stability. Forest homogenization through fire suppression and past logging may collapse the stability landscape into a biphasic regime dominated by SBW and FTC, whereas increasing compositional and structural diversity can expand it into multiphasic regimes that attenuate disturbance amplitudes and promote asynchronous dynamics—underscoring the role of diversity–stability and resilience principles in guiding forest management.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 9","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148902311","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}

By combining mono- and coculture assays with genome-scale metabolic modeling and metabolomic profiling of spent media, we characterized directional interactions and resource dependencies among community members. Our findings show that positive interactions dominated the community network, accounting for 55% of all pairwise combinations, indicating a high prevalence of growth-promoting effects among strains. Genome-scale metabolic modeling showed that functional divergence among strains enhanced the potential for metabolic complementarity as phylogenetic distance increased. Integrating metabolic modeling with metabolomics further suggested that <i>Pseudomonas azotifigens</i> Q6 not only benefited from all other community members, but also exhibited mutualistic interactions with the other three strains, with metabolite exchange involving compounds such as L-lysine and L-cysteine. <i>Pseudomonas azotifigens</i> Q6 acted as an important driver of community composition by affecting the abundance of several other consortium members in vitro.
