The root microbiome is composed of an incredibly diverse microbial community that provides services to the plant. A major question in rhizosphere research how species communities interact with each other and their host. In nutrient mutualism between host plants arbuscular mycorrhizal fungi (AMF), competition often leads certain dominating colonization, outcome being dependent on environmental conditions. past, it has been difficult quantify abundance closely related track competitive...
Species that evolved through ecological speciation and lack intrinsic genetic incompatibilities may nonetheless be maintained by extrinsic postmating isolating barriers impose selection against hybrids. These species, however, vulnerable to a breakdown in isolation. Here, we investigate model system for speciation: sympatric limnetic-benthic pairs of threespine sticklebacks. Recently, stickleback hybrid abundance Enos Lake has increased. Given hybrids was historically an important component...
There are now a number of well-studied cases in which hybridization between closely related sympatric species has increased, sometimes resulting the replacement pairs by hybrid swarms. Many these have been linked to anthropogenic environmental change, but mechanisms leading from change collapse, and long-term effects on pairs, remain poorly understood. We used an individual-based stochastic simulation model explore conditions under disturbances that weaken premating barriers reproduction...
Abstract Human land use causes major changes in species abundance and composition, yet native exotic can exhibit different responses to change. Native populations generally decline human‐impacted habitats while often benefit. In this study, we assessed the effects of human on reptile diversity, including functional which relates range habitat strategies biotic communities. We surveyed 114 communities from localities that varied structure impact level two Caribbean islands, calculated...
Abstract Infrastructure systems have direct implications for how health and well-being evolve across urban–rural systems. Scientists, practitioners, policy-makers use domain-specific methods tools to characterize sectors of infrastructure, but these approaches do not capture the cascading effects interrelated infrastructure governance domains. We argue that development management sustainable urban must focus on interactions rural places advance equitable well-being. call a research agenda...
Aim : Island biogeography theory states that species richness increases with habitat diversity and decreases isolation from source pools. However, ecological must incorporate effects of human activity to explain contemporary patterns biodiversity. We contemporized island by conceptualizing trajectories how changes over time accelerating land development economic trade, which increase extinction immigration rates, respectively. With this theory, we then articulate empirically assess expected...
Abstract The long-horned tick, Haemaphysalis longicornis Neumann (Ixodida: Ixodidae) was recently introduced to the United States from its native range in Asia. Although H. transmits numerous disease-causing pathogens range, it is unclear what extent will act as a disease vector States. ability of acquire likely depends on overlap with resident tick species both habitat and transmitted within range. To assess potential between invasive species, we field-collected ticks across southeastern...
Global variation in species richness is widely recognized, but the explanation for what drives it continues to be debated. Previous efforts have focused on a subset of potential drivers, including evolutionary rate, time (maximum clade age restricted region), dispersal (migration from one region another), ecological factors and climatic stability. However, no study has evaluated these competing hypotheses simultaneously at broad spatial scale. Here, we examine their relative contribution...
Summary Statistical models of ecosystem functioning based on species traits are valuable tools for predicting how nutrient cycling will respond to global change. However, such as arbuscular mycorrhizal fungi ( AMF ) have evolved high intraspecific trait variation, making characterization and inclusion in functional difficult. We present a five‐part framework experimental designs from the phenotypic plasticity literature quantify variation context. Framework experiments involve exposing...
Ecological research often involves sampling and manipulating non-model organisms that reside in heterogeneous environments. As such, ecologists adapt techniques ideas from industry other scientific fields to design build equipment, tools, experimental contraptions custom-made for the ecological systems under study. Three-dimensional (3D) printing provides a way rapidly produce identical novel objects could be used studies, yet have been slow adopt this new technology. Here, we provide with...
Economic impacts from plant pests are often felt at the regional scale, yet some expand to global scale through alignment of a pest's invasion potentials. Such globally invasive species (i.e., paninvasives) like human pathogens that cause pandemics. Like pandemics, assessing paninvasion risk for an emerging pest is key stakeholders take early actions avoid market disruption. Here, we develop severity assessment framework and use it assess rapidly spreading U.S. grape pest, spotted lanternfly...
Abstract Aim Examining the biogeography of body size is crucial for understanding how animal communities are assembled and maintained. In tetrapods, varies predictably with temperature, moisture, productivity seasonality topographical complexity. Although millennial‐scale human pressures known to have led extinction primarily large‐bodied pressure history often ignored in studies that focus on extant species. Here, we analyse 11,377 tetrapod species Western Hemisphere test whether left an...
Our understanding of broad-scale biodiversity and functional trait patterns is largely based on plants, relatively little information available soil arthropods. Here, we investigated the distribution termite diversity globally morphological traits across China. analyses showed increasing species richness with decreasing latitude at both globally, within-China. In addition, detected obvious latitudinal trends in mean community value average, body size leg length latitude. Furthermore,...
Conversion of tropical forests into agriculture may present a serious risk to amphibian diversity if amphibians are not able use agricultural areas as habitat. Recently, in Xishuangbanna Prefecture, Yunnan Province – hotspot frog within China two-thirds the native rainforests have been converted rubber plantation agriculture. We conducted surveys and experiments quantify habitat for breeding non-breeding life history activities species rainforest, other human impacted sites. Rubber sites had...
Urban development and species invasion are two major global threats to biodiversity. These often co-occur, as developed areas more prone invasion. However, few empirical studies have tested if both factors affect biodiversity in similar ways. Here we study the individual combined effects of urban plant on composition arthropod communities. We assessed 36 paired invaded non-invaded sample plots, by Antigonon leptopus, with half these pairs located natural other land-use types Caribbean island...
In the Anthropocene, ranges of introduced species are expanding, while extinction‐prone contracting. Introductions and extinctions caused by how respond to human impacts, but it is unknown why some expand contract. Here, we test whether this opposite response impact due falling at ends geographic, evolutionary, or ecological trait continua. We constructed a database native range maps, traits, phylogenetic relationships, introduction status squamate reptiles with Western Hemisphere. Across...
1. While it is clear that land‐use change significantly impacts the taxonomic dimension of soil biodiversity, how functional responds to less well understood. 2. This study examined transformation primary forests into rubber tree monocultures individual termite species and this reflected in α‐diversity (within site) β‐diversity (among sites). 3. Overall, responded strongly change, whereby only 11 27 found were able tolerate both habitats. These differences caused a 27% reduction richness...
Globally, geckos (Gekkonidae) are one of the most successful reptile families for exotic species.With exception widespread invader, Hemidactylus mabouia, however, introductions gecko species a more recent occurrence in Caribbean islands despite extensive surrounding region.Here we report three new establishments on mid-sized island Curaçao (Leeward Antilles).Of species, mourning gecko, Lepidodactylus lugubris (Duméril and Bibron, 1836) has largest distribution likely been established longest...
