Abstract The use of biologging devices continues to increase with technological advances yielding remarkable ecological insights and generating new research questions. However, as develop are deployed more widely, there is a need update our knowledge the potential ethical impacts allow scientists balance these against gained. We employed suite phylogenetically controlled meta‐analyses on dataset comprising than 450 published effect sizes across 214 different studies examine effects biologger...
ABSTRACT In this paper, we argue that the concept of ‘species’ should not be main focus research and policies in biodiversity conservation. Diversity is important at all levels life: within species as well among them ecosystems. First, give a brief overview debate about necessity to find unified ‘species’. this, side with Charles Darwin, who insisted no strict definition could given term, which ultimately matter arbitrary pragmatic human language. This did worry neither it concern biologists...
Abstract Maintaining genetic diversity is a crucial component in conserving threatened species. For the iconic Australian koala, there little information on wild populations that not either skewed by biased sampling methods (e.g., effort toward urban areas) or of limited usefulness due to low numbers microsatellites used. The ability genotype DNA extracted from koala scats using next‐generation sequencing technology will only help resolve location sample bias but also improve accuracy and...
In estuaries, fluctuating environmental conditions exact strenuous physiological demands on the fishes that inhabit these oft-impacted areas, including Critically Endangered delta smelt Hypomesus transpacificus in California (USA). Using an archive of otoliths spanning 2011-2019, we examined how growth rates wild subadult vary ontogenetically, regionally, and relation to variation physical environment during late-summer fall upper San Francisco Estuary. Recent were quantified using otolith...
Abstract Effective conservation requires accurate data on population genetic diversity, inbreeding, and structure. Increasingly, scientists are adopting non‐invasive sampling (gNIS) as a cost‐effective population‐wide monitoring approach. gNIS has, however, known limitations which may impact the accuracy of downstream analyses. Here, using high‐quality single nucleotide polymorphism (SNP) from blood/tissue free‐ranging koala ( n = 430), we investigated how reduced SNP panel size call rate...
Wildlife diseases are a recognized driver of global biodiversity loss, have substantial economic impacts, and increasingly becoming threat to human health. Disease surveillance is critical but remains difficult in the wild due costs potential biases associated with most disease detection methods. Noninvasive scat surveys been proposed as health monitoring methodology overcome some these limitations. Here, we use known Chlamydia iconic, yet vulnerable, koala Phascolarctos cinereus compare...
Abstract Vegetation clearing has been implicated as a major contributor to biodiversity loss. It therefore stands reason that developers should face regulatory requirement assess potential impacts and avoid, mitigate compensate for loss of vegetation wherever proposed infrastructure developments impact on considered be habitat threatened species. Environmental Impact Assessments ( EIA ) rely accurate information describe the distributions species within footprint developments, which is...
Abstract Habitat destruction and fragmentation are increasing globally, forcing surviving species into small, isolated populations. Isolated populations typically experience heightened inbreeding risk associated depression population decline; although individuals in these may mitigate risks through avoidance strategies. For koalas, as dietary specialists already under threat the northern parts of their range, increased habitat costs great conservation concern. Koalas known to display passive...
Abstract The on-going anthropogenic degradation of freshwater habitats has drastically altered the environmental supply both nutrients and common pollutants. Most organisms living in these experience interactive effects various stressors that can initiate adjustments at multiple levels impacting their fitness. Hence, studies measuring response to a single parameter fail capture complexities status quo. We tested individual effect arsenic (As) exposure, food quantity, dietary phosphorus...
The genetic consequences of the subdivision populations are regarded as significant to long-term evolution, and research has shown that scale speed at which this is now occurring critically reducing adaptive potential most species inhabit human-impacted landscapes. Here, we provide a rare and, our knowledge, first analysis process while it happening demonstrate method evaluating effect mitigation measures such fauna crossings. We did by using an extensive data set collected from koala...
The koala, one of the most iconic Australian wildlife species, is facing several concomitant threats that are driving population declines. Some well known and have clear methods prevention (e.g., habitat loss can be reduced with stronger land-clearing control), whereas others less easily addressed. One major current to koalas chlamydial disease, which impacts on individual survival reproduction rates translate into Effective management strategies for disease in wild currently lacking, and,...
To compare cine MR b-TFE sequences acquired before and after gadolinium injection, on a 3T scanner with parallel RF transmission technique in order to potentially improve scanning time efficiency when evaluating LV function.25 consecutive patients scheduled for cardiac MRI were prospectively included had their right gadobutrol injection. Images assessed qualitatively (overall image quality, edge sharpness, artifacts wall motion) quantitatively measurement of LVEF, mass, telediastolic volume...
Environmental Impact Assessments (EIAs) are at the frontline of balancing economic, societal and environmental needs. With world expected to invest around $90 trillion in infrastructure next 15 years, resulting more new than is currently existence globally (Jan Corfee-Morlot et al., 2016), there has never been a critical time for EIAs get it right. Yet even Australia, wealthy, economically politically stable nation with multiple laws comparatively effective governance, legislation failed...

<h3>Purpose</h3> Prenatal MRI with novel motion-correction techniques has the potential to improve fetal diagnosis of congenital heart disease in clinically challenging cases. We sought quantify added value for fetuses an unresolved echocardiographic diagnosis. <h3>Methods</h3> Only patients incomplete were referred MRI. Standard 'HASTE' images (2D) acquired, and then reconstructed using a motion corrected slice-volume-registration algorithm generate navigable 3D volumes (3DV) segmented...
Linear infrastructure stands as one of the main culprits anthropogenically caused biodiversity decline. As it fragments landscapes, ultimately results in a myriad direct and indirect ecological consequences for wildlife. transportation networks will continue to grow under increasing human population growth, decline making need understand mitigate their impact on species an urgent conservation worldwide. The implementation mitigation measures alleviate barrier effect produced by linear...
Potential subdivision events in populations can have a wide range of causes: from natural disasters like bushfires that isolate communities, to anthropogenic disturbances infrastructure projects cutting through population’s habitat. Due the unpredictability inherent bushfires, or even for predictable such as property development, affected by these potential subdivisions are often not studied until after event, making it extremely hard assess negative conservation impacts without benefit...
