Benchmark studies of insect populations are increasingly relevant and needed amid accelerating concern about trends in the Anthropocene. The growing recognition that may be decline has given rise to a renewed call for population monitoring by scientists, desire from broader public participate surveys. However, due immense diversity insects vast assortment data collection methods, there is general lack standardization such sudden unplanned expansion fail meet its ecological potential or...
As human density increases, biodiversity must increasingly co-exist with urbanization or face local extinction. Tolerance of urban areas has been linked to numerous functional traits, yet few globally consistent patterns have emerged explain variation in tolerance, which stymies attempts at a generalizable predictive framework. Here, we calculate an Urban Association Index (UAI) for 3,768 bird species 137 cities across all permanently inhabited continents. We then assess how this UAI varies...
Changes in phenology response to ongoing climate change have been observed numerous taxa around the world. Differing rates of phenological shifts across trophic levels led concerns that ecological interactions may become increasingly decoupled time, with potential negative consequences for populations. Despite widespread evidence and a broad body supporting theory, large-scale multitaxa demographic asynchrony remains elusive. Using data from continental-scale bird-banding program, we assess...
Geographically isolated populations of birds often differ in song. Because choose mates on the basis their song, song differentiation between constitutes a behavioral barrier to reproduction. If this is judged be sufficiently strong, then with divergent songs may merit classification as distinct species under biological concept. We used dataset 72 pairs related but allopatric Neotropical passerines ("taxon pairs") compare 2 methods for measuring divergence populations: statistical analysis 7...
Bees are essential pollinators for many flowering plants, including agriculturally important crops such as apple. As geographic ranges of bees or their host plants change a result human activities, we need to identify pathogens that could be transmitted among newly sympatric species evaluate and anticipate effects on bee communities. We used PCR screening DNA sequencing exposure potentially disease-causing microorganisms in pollinator apple, the horned mason (Osmia cornifrons). did not...
Plasticity is often thought to accelerate trait evolution and speciation. For example, plasticity in birdsong may partially explain why clades of song learners are more diverse than related with innate song. This "song learning" hypothesis predicts that (1) differences traits evolve faster learners, (2) behavioral discrimination against allopatric (a proxy for premating reproductive isolation) evolves learners. We tested these predictions by analyzing acoustic conducting playback experiments...
Why are speciation rates so variable across the tree of life? One hypothesis is that this variation explained by how rapidly reproductive barriers evolve. We tested conducting a comparative study evolution bird song, premating barrier to reproduction. Speciation in birds typically initiated when geographically isolated (allopatric) populations evolve barriers. measured strength song as between closely related allopatric 2339 field experiments measure discrimination for 175 taxon pairs or...
Bicknell's Thrush (Catharus bicknelli) is a threatened species that inhabits high-elevation spruce–fir forests in the northeastern United States. populations are predicted to shift upslope response global warming, leading local extinctions on mountains lack elevational extent accommodate such shifts. However, biotic interactions may influence how montane respond changing abiotic conditions. In territorial songbirds, for example, aggression from dominant low-elevation has been hypothesized...
Adaptation is evolution in response to natural selection. Hence, an adaptation expected originate simultaneously with the acquisition of a particular selective environment. Here we test whether long legs evolve oil-collecting Rediviva bees when they come under selection by long-spurred, oil-secreting flowers. To quantify environment, drew large network interactions between species and plant species. The environment each bee was summarized as average spur length interacting weighted...
In animal societies, behavioral idiosyncrasies of the individuals often guide which tasks they should perform. Such personality-specific task participation can increase individual efficiency, thereby improving group performance. While several recent studies have documented group-level benefits within-group (i.e., personality) diversity, how these are realized at level is unclear. Here we probe individual-level personality-driven in social spider Stegodyphus dumicola. S. dumicola, presence...
Abstract Biodiversity is in crisis, and insects are no exception. To understand insect population community trends globally, it necessary to identify synthesize diverse datasets representing different taxa, regions, habitats. The relevant literature is, however, vast challenging aggregate. Entomological Global Evidence Map (EntoGEM) project a systematic effort search for catalogue studies with long‐term data that can be used changes abundance diversity. Here, we present the overall EntoGEM...
Do related populations that are separated by barriers predictably evolve differences from one another over time, or is such divergence idiosyncratic and unpredictable? We test these alternatives investigating patterns of trait evolution for 54 sister pairs Andean forest birds live in similar environments on either side the arid Marañón Gap, a strong dispersal barrier humid montane species. measured both sexual (song plumage) ecological (beak size beak shape) traits. Sexual traits clock-like...
Abstract Social spiders are thought to predominantly receive information about their environment through vibrational cues. Thus, group living introduces the challenge of distinguishing useful from background noise nestmates. Here we investigate whether spatial proximity between colony-mates may allow social ( Stegodyphus dumicola ) reduce that might obstruct prey. To do so, constructed experimental colonies and measured number in one another whilst resting could predict participated prey...
In response to biodiversity loss and biotic community homogenization in urbanized landscapes, there are increasing efforts conserve increase within urban areas. Accordingly, around the world, previously extirpated species (re)colonizing otherwise infiltrating while other disappearing from these landscapes. Tracking occurrence of traditionally intolerant tolerant should be a management goal areas, but we generally lack tools study this phenomenon. To address gap, first used species'...
A leafminer reared in California from Cape ivy (Asteraceae: Delairea odorata Lem.), an invasive plant introduced South Africa, is identified as Liriomyza temperata Spencer (Diptera: Agromyzidae). This believed to be a novel host association for native Nearctic fly, which appears have been Hawaii along with ivy. tricornis Lonsdale syn. nov. treated junior synonym of L. temperata. There are no previous records either taxon. We review previously published rearing North American spp. other...
In conifer forests of western North America, wildlife populations can change rapidly in the decade following wildfire as trees die and animals respond to concomitant resource pulses that occur across multiple trophic levels. particular, black-backed woodpeckers (Picoides arcticus) show predictable temporal increases then declines fire; this trajectory is widely believed be a response woodpeckers' main prey, woodboring beetle larvae families Buprestidae Cerambycidae, but we lack understanding...
