Abstract Animal tracking data are being collected more frequently, in greater detail, and on smaller taxa than ever before. These hold the promise to increase relevance of animal movement for understanding ecological processes, but this potential will only be fully realized if their accompanying location error is properly addressed. Historically, coarsely-sampled have proved invaluable large scale processes (e.g., home range, habitat selection, etc.), modern fine-scale unlock far...
The relationship between the production of dimethylsulfide (DMS) in upper ocean and atmospheric sulfate aerosols has been confirmed through local shipboard measurements, global modeling studies alike. In order to examine whether such a connection may be recoverable satellite record, we have analyzed correlation mean surface chlorophyll (CHL) aerosol optical depth (AOD) Southern Ocean, where marine atmosphere is relatively remote from anthropogenic continental influences. We carried out...
Abstract The red fox ( Vulpes vulpes ) is one of the most adaptable carnivorans, thriving in cities across globe. We used GPS-tracking five suburban foxes high-density residential suburbs Perth, Western Australia to quantify (1) their habitat selection and (2) home range area. All showed statistically significant avoidance locations (p < 0.001) preference for parkland 0.001), with native vegetation reserves, golf courses, water reserves showing disproportionately greater use. Landuse...
The sea-to-air flux of the biogenic sulfur (S) compound dimethylsulfide (DMS) is thought to constitute an important radiative impact on climate, especially in remote marine areas. Previous biogeochemical modelling analyses simulate medium large changes DMS polar regions under warming scenarios. Here we assess global such a prescribed change contemporary climate using low-resolution atmospheric general circulation model. This operates through oxidation radiatively-active sulfate aerosols,...
Glyphosate has become the most commonly used herbicide worldwide and is reputedly environmentally benign, nontoxic, safe for use near wildlife humans. However, studies indicate its toxicity underestimated persistence in environment greater than once thought. Its actions as a neurotoxin endocrine disruptor potential to act similar ways persistent organic pollutants such organochlorines dichlorodiphenyltrichloroethane (DDT) dioxin. Exposure glyphosate glyphosate-based herbicides both people...
The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back 40 Ma. Recent studies, however, suggest that much Sulawesi's fauna assembled over the last 15 Myr. Here, we test hypothesis more recent uplift submerged portions land promoted diversification and its faunal assemblage is younger than island itself. To do so, combined palaeogeographical reconstructions with genetic morphometric datasets derived from three largest mammals: babirusa,...
Abstract Very high‐resolution ( VHR ) image data, including from unmanned aerial vehicle UAV platforms, are increasingly acquired for wildlife surveys. Animals or structures they build (e.g. nests) can be photointerpreted these images, however, automated detection is required more efficient We developed semi‐automated analyses to map white‐bellied sea eagle Haliaeetus leucogaster nests in photographs of the Houtman Abrolhos Islands, Western Australia, an important breeding site many seabird...
European white stork are long considered to diverge eastern and western migration pools as a result of independent overwintering flyways. In relatively recent times, the northern distribution has been subject dramatic population declines country-specific extirpations. A number reintroduction programs were started in mid 1950s bring storks back historical ranges. Founder individuals sourced opportunistically from Eastern Western distributions Algeria, leading significant artificial mixing...

The White-bellied Sea-Eagle, Haliaeetus leucogaster, is monomorphic for adult plumage colouration, but in body size displays reversed sexual dimorphism, with female birds significantly larger. Analyses of morphometric data from 37 individuals Australia and Papua New Guinea revealed a latitudinal cline dimensions, larger the south. A discriminant function based on 10 characters was 100% effective discriminating between 19 males 18 females that had been sexed using molecular genetic methods....
ABSTRACT The collection of baseline health data is an essential component endangered species conservation program. As for many wildlife species, there are minimal available wild populations the Carnaby’s cockatoo (Zanda latirostris). In this study, 426 nestlings were sampled from nine breeding sites throughout range over 11-year period. addition to a physical examination, samples collected test hematologic and biochemical parameters, psittacine beak feather disease virus (BFDV), avian...

Abstract The White‐bellied Sea‐Eagle Haliaeetus leucogaster (Accipitridae) is widespread within Australia. However, in a number of states it thought to be declining locally response human induced disturbance. Here we analyse the Australian Bird Atlas data identify extent and pattern change range density species between three Periods (1901–1976, 1977–1981 1998–2001) using new standardized frequency measure, Occupancy Index (OI) for 1° blocks (approx. 100 km 2 ) across continent. At...

ABSTRACT Establishing integration of an individual bird into a wild flock is particularly important in species that are highly gregarious and reliant on the to increase their likelihood survivorship. When individuals, rehabilitated reintroduced flocks, tracked through satellite or global positioning system (GPS) telemetry, it further significance establish assess rehabilitation success whether can serve as marker flock. To date, for black cockatoos ( Calyptorhynchus spp.) this has been...
Conservation of breeding seabirds typically requires detailed data on where they feed at sea. Ecological niche models (ENMs) can fill gaps, but rarely perform well when transferred to new regions. Alternatively, the foraging radius approach simply encircles sea surrounding a seabird colony (a circle), overestimates habitat. Here, we investigate whether ENMs transfer (predict) niches tropical between global colonies, and refine circles. We collate large dataset tracks (12000 trips, 16...
