Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense also affects tolerance to abiotic stressors. Urban-rural gradients associated with the of clines 47% throughout world. Variation strength was explained changes drought stress and vegetation cover varied...
Abstract Conservation science is a morally motivated field, with implicit and explicit values built into its practice. As such, conservationists must engage conservation ethics to interrogate underlying values. We examine cutting‐edge ecological contemporary revisit two norms that have become dogmatic in the field: collectives, but not individual animals, are valuable anthropomorphism should be staunchly avoided. Emerging studies demonstrate individuals their intraspecific variation can...
Across all taxa, amphibians exhibit some of the strongest phenological shifts in response to climate change. As climates warm, and other animals are expected breed earlier temperature cues. However, if species use fixed cues such as daylight, their breeding timing might remain fixed, potentially creating disconnects between life history environmental conditions. Wood frogs Rana sylvatica a cold‐adapted that reproduce early spring, immediately after ponds free ice. We used long‐term surveys...
Abstract In tropical forests, understory herbaceous angiosperms (herbs), which can comprise up to 40% of plant species richness, have received relatively little attention compared with trees, and their diversity patterns drivers remain poorly understood. While tree has been shown be driven primarily by water availability, we hypothesized that herb may equally or more limited light availability. To test the importance in shaping diversity, surveyed communities 13 one‐ha plots along a rainfall...
Abstract Accurate estimates of forest canopy structure are central for a wide range ecological studies. Hemispherical photography (HP) is popular tool to estimate attributes. However, traditional HP methods require expensive equipment, sensitive exposure settings, and produce limited resolution which dramatically affects the accuracy gap fraction estimates. As an alternative, hemispherical images can be extracted from spherical panoramas produced by many smartphone camera applications. I...
Rats thrive in human-dominated landscapes, and have expanded to a near global distribution. Norway rats (Rattus norvegicus) contaminate food, damage infrastructure, are reservoirs for zoonotic pathogens causing human diseases. To limit these negative impacts, entities around the world implement intervention control strategies designed quickly drastically reduce number of population. While primary goal interventions is rat numbers their detrimental activities, there important, yet unexplored,...
Environmental change is predicted to accelerate into the future and will exert strong selection pressure on biota. Although many species may be fated extinction, others survive through their capacity evolve rapidly at highly localized (i.e., microgeographic) scales. Yet, even as new examples have been discovered, limits such evolutionary responses not often evaluated. One of first microgeographic variation involved pond populations wood frogs (Rana sylvatica). separated by just tens hundreds...
Abstract Countergradient variation has been detected in diverse taxa. In a common manifestation, individuals from colder environments develop faster than conspecifics warmer when placed garden. Where such pattern exists, it implies trade‐off: Individuals have intrinsic rates of development lower those demonstrated by other the same species. We explored trade‐off between rate and locomotor performance wood frog ( Rana sylvatica ), an amphibian for which countergradient well documented. reared...
Understanding drivers of metapopulation dynamics remains a critical challenge for ecology and conservation. In particular, the degree synchrony in determines how resilient is to widespread disturbance. this study, we used 21 years egg mass count data across 64 nonpermanent freshwater ponds Connecticut, USA evaluate patterns abundance growth assess regional as well local factors shaping population wood frogs (Rana sylvatica = Lithobates sylvaticus). asked whether species known undergo...
Predation risk causes prey to react in numerous ways, from life history changes shifts habitat. These responses give some insight into how different types of predators affect prey, but are often not comparable across taxa and experimental systems. Metabolism is a ubiquitous trait among living organisms, which offers way examine predator effects create generalizable outcomes. We examined metabolic terrestrial aquatic three antipredator functional groups under varied contexts cues. found that...
Eastern Box Turtle (Terrapene carolina) populations have declined drastically since 1970 because of continued destruction and fragmentation their habitat. Although they are known to shift home ranges environmental degradation, it is unknown how solar arrays impact Turtles. From 2011–2018, we collected data on movement occupancy in a 79-ha farm. The farm divided into six fenced areas, each containing wildlife openings for terrestrial fauna every 23 m around the arrays. We hypothesized that...
Over the past two decades, our knowledge of ecological impacts roads has increased rapidly. It is now clear that environmental effects transportation infrastructure are inextricable from benefits to economic, social, and cultural values. Despite necessity optimizing these multiple values, road planners, scientists, practitioners have no established methodology or pluralistic approach address growing ethical complexities. We articulate five issues could be addressed by developing an ethic...
Hypomelanism in natural populations is rare and has been anecdotally associated with developmental retardation mortality when present anuran larvae. We report multiple, recent cases of hypomelanism across 5 2 counties Connecticut. also experimentally confirm that this phenotype extremely delayed metamorphosis increased mortality.
Abstract Hemispherical photography (HP) is one of the most commonly employed methods to estimate forest canopy structure and understory light environments. Traditional require expensive, specialized equipment, are tedious deploy, sensitive exposure settings. In contrast, modern smartphone cameras readily available make use ever-improving software produce images with high dynamic range clarity, but lack suitable hemispherical lenses. Thus, despite fact that almost all ecologists foresters...
Mink Frogs (Rana septentrionalis) are a unique ranid species restricted to Canada and the northern edge of United States, from Minnesota Maine. They member Aquarana clade that includes Green (R. clamitans), American Bullfrogs catesbeiana), four other species. Despite being relatively common where present, biology this has been poorly studied little in particular is known about its breeding development fertilization through overwintering as larvae. Critically, species' representation museum...
