Abstract In ecology, researchers frequently use observational studies to explain a given pattern, such as the number of individuals in habitat patch, with large explanatory (i.e., independent) variables. To elucidate relationships, ecologists have long relied on hypothesis testing include or exclude variables regression models, although conclusions often depend approach used (e.g., forward, backward, stepwise selection). Though better tools surfaced mid 1970's, they are still underutilized...
Detecting individuals of amphibian and reptile species can be a daunting task. Detection hindered by various factors such as cryptic behavior, color patterns, or observer experience. These complicate the estimation state variables interest (e.g., abundance, occupancy, richness) well vital rates that induce changes in these survival probabilities for abundance; extinction occupancy). Although ad hoc methods counts uncorrected detection, return rates) typically perform poorly face no they...
An increasing proportion of ecological studies examine landscape effects on the phenomena they address. We reviewed which simultaneously considered landscape-scale and patch-scale in order to answer following question: does inclusion characteristics as explanatory variables increase our ability predict species presence abundance when local (i.e., habitat patch) conditions are known? The 61 selected cover a wide array taxa, types, variables, but many (36%) focused avian communities forests...
Automated sensors have potential to standardize and expand the monitoring of insects across globe. As one most scalable fastest developing sensor technologies, we describe a framework for automated, image-based nocturnal insects—from development field deployment workflows data processing publishing. Sensors comprise light attract insects, camera collecting images computer scheduling, storage processing. Metadata is important sampling schedules that balance capture relevant ecological...
Pond-breeding amphibians frequently encounter roads during their movements across the landscape to reach breeding, summering, or hibernation sites. Through night driving surveys conducted each summer from 1995–2002 on a 20-km stretch of secondary road within national park eastern Canada, I evaluated whether traffic had cumulative effects amphibian abundance over this period. also investigated effect nightly variations in intensity number killed road. recorded total 4643 crossing events 37...
Many investigators have hypothesized that landscape attributes such as the amount and proximity of habitat are important for amphibian spatial patterns. This has produced a number studies focusing on effects characteristics patterns occurrence in patches or ponds, most which conclude is important. We identified two concerns associated with these studies: one deals their applicability to other types, been conducted agricultural landscapes; highlights need account probability detection. tested...
An animal's capacity to recolonize a patch depends on at least two components: its ability detect the and reach it. However, disruption of such processes by anthropic disturbances could explain low animal abundance patterns observed many investigators in certain landscapes. Through field experiments, we compared orientation homing success northern green frogs (Rana clamitans melanota Rafinesque, 1820) leopard pipiens Schreber, 1782) translocated across disturbed or undisturbed surfaces. We...
Nocturnal car traffic often results in amphibian casualties, especially during rainy nights. The behavior of amphibians presumably influences their vulnerability to mortality on the road, but this hypothesis remains untested. We investigated behavioral response individuals six species roads when confronted by an approaching vehicle. first conducted a field study consisting 50 night-driving surveys over 4 yr which we recorded (i.e., moving or immobile) frogs, toads, tree and salamanders...
Abstract Monitoring rodent abundance is critical to understand direct and indirect trophic interactions in most northern terrestrial ecosystems. However, logistic constraints can prevent researchers from using capture–mark–recapture methods, a robust approach estimate abundance. Our objective was determine the correlation between estimates of Arctic lemmings obtained live‐trapping data with spatially explicit capture–recapture models ( SECR ; N/ha) indices snap‐trapping along trap lines...
Halogenated flame retardants (HFRs) are contaminants that abundantly emitted from waste management facilities (WMFs) and became ubiquitous in air of urbanized regions. Urban birds including gulls have adapted to exploiting human food resources (refuse) WMFs, thus experienced population explosions worldwide. However, foraging WMFs for may result exposure HFRs been shown be toxic animals. The objective this study was determine the influence near or various on atmospheric HFRs, localize other...
Summary 1. Peatlands have suffered great losses following drainage for agriculture, forestry, urbanisation, or peat mining, near inhabited areas. We evaluated the faunal and vegetation patterns after restoration of a peatland formerly mined peat. assessed whether bog pools created during are similar to natural in terms water chemistry, structure composition, as well amphibian arthropod occurrence patterns. 2. Both avian species richness cover at site increased restoration. Within pools,...
Forest understory vegetation is an important characteristic of the forest. Predicting and mapping a critical need for forest management conservation planning, but it has proved difficult with available methods to date. LiDAR potential generate remotely sensed structure data, this yet be fully validated. Our objective was examine capacity point cloud data predict cover. We modeled ground-based observations in three vertical strata (0.5 m < 1.5 m, 2.5 3.5 m) as function variety metrics using...
