“…In addition, increased LUC associated with ONGD could indirectly mediate food availability through changes in habitat and/or water quality (Crowder and Cooper 1982 augment in-stream primary production , benefiting algivorous species and negatively affecting other species. Many of these modifications to habitat, water quality, and basal food availability have been observed in streams surrounded by ONGD in shale plays in the Appalachians (Olmstead et al 2013), in Arkansas (Johnson et al 2015, Baker et al 2018, and in Wyoming (Godwin et al 2015, Girard and Walters 2018, Walters et al 2019). But given the diversity of stressors associated with the different land-uses and their variable effects, it is essential that we continue to understand and identify how different land-use activities influence important mechanistic pathways for different species.…”

Anthropogenic activities, such as oil and natural gas development (ONGD), have significantly altered the landscape. It is often challenging to identify the mechanistic processes underlying ecological responses to land‐use change (LUC). In aquatic ecosystems, alterations to habitat and food availability and water quality associated with increased LUC are key mechanistic pathways that deserve management consideration. We used structural equation modeling to evaluate how LUC associated with ONGD could influence macroinvertebrate and fish across 40 sites in six headwater streams in the Wyoming Range of the Upper Green River Basin, Wyoming. The most important mechanistic pathway varied, but responses were frequently driven by a direct effect of LUC or related to changes in food availability and water quality. Habitat complexity was the least important mechanistic pathway in our models. Our results also highlight that responses may reflect an organism's degree of habitat or resource specialization and/or sensitivity to changes in water quality. Habitat pathways were more important for habitat specialists (e.g., Mottled Sculpin, Cottus bairdii), food pathways were more important for food specialists (e.g., Colorado River Cutthroat Trout, Oncorhynchus clarki pleuriticus; Mountain Sucker, Catostomus platyrhynchus), and sensitivity to increased salinity was important for intolerant species (e.g., O. clarki, C. bairdii, and predatory macroinvertebrates). Continued identification of the specific mechanisms underlying species’ responses to increased LUC will aid in the conservation of ecologically and economically important species.

“…In most studies using a DNA trapping strategy (90%), researchers employed bait or lures to increase the yield of their traps. Very few studies used non-lured DNA traps, for example, barb wire placed at sites used by brown bears (Ursus arctos) (Karamanlidis et al, 2014;Quinn et al, 2014) or modified body snares at otter (Lontra canadensislatin) latrine sites, to collect hair (Godwin et al, 2015). Although it seems perfectly legitimate (and often essential) to increase the attractiveness of DNA traps with food (Cohen et al, 2013), scent marks from other individuals (Anile et al, 2012) or other attractants (e.g.…”

The use of DNA data is ubiquitous across animal sciences. DNA may be obtained from an organism for a myriad of reasons including identification and distinction between cryptic species, sex identification, comparisons of different morphocryptic genotypes or assessments of relatedness between organisms prior to a behavioural study. DNA should be obtained while minimizing the impact on the fitness, behaviour or welfare of the subject being tested, as this can bias experimental results and cause long-lasting effects on wild animals. Furthermore, minimizing impact on experimental animals is a key Refinement principle within the '3Rs' framework which aims to ensure that animal welfare during experimentation is optimised. The term 'non-invasive DNA sampling' has been defined to indicate collection methods that do not require capture or cause disturbance to the animal, including any effects on behaviour or fitness. In practice this is not always the case, as the term 'non-invasive' is commonly used in the literature to describe studies where animals are restrained or subjected to aversive procedures. We reviewed the non-invasive DNA sampling literature for the past six years (380 papers published in 2013-2018) and uncovered the existence of a significant gap between the current use of this terminology (i.e. 'non-invasive DNA sampling') and its original definition. We show that 58% of the reviewed papers did not comply with the original definition. We discuss the main experimental and ethical issues surrounding the potential confusion or misuse of the phrase 'non-invasive DNA sampling' in the current literature and provide potential solutions. In addition, we introduce the terms 'non-disruptive' and 'minimally disruptive' DNA sampling, to indicate methods that eliminate or minimise impacts not on the physical integrity/structure of the animal, but on its behaviour, fitness and welfare, which in the literature reviewed corresponds to the situation for which an accurate term is clearly missing. Furthermore, we outline when these methods are appropriate to use.

“…A handful of articles that focus on specific species demonstrate that land fragmentation contributes to animals avoiding roadways, which isolates them to smaller areas of land, a trend documented in grassland bird species (Thompson et al 2015), salamanders (Brand et al 2014), mule deer (Lendrum et al 2012), and river otters (Godwin et al 2015). Although land fragmentation is not likely to have a big impact on livestock and companion animals, range restrictions might; despite this possibility, studies of the impacts of HVHHF on livestock and companion animals are scarce.…”

Exploring the Place of Animals and Human–Animal Relationships in Hydraulic Fracturing Discourse

Throughout human history, energy security has been a prominent concern. Historically, animals were used as energy providers and as companions and sentinels in mining operations. While animals are seldom used for these purposes in developed communities today, this legacy of use is likely to have far-reaching consequences for how animals and human–animal relationships are acknowledged in energy development. The US is currently experiencing an energy boom in the form of high volume horizontal drilling and hydraulic fracturing (HVHHF); because animals are the most at risk from this boom, this study uses a thorough content analysis of peer-reviewed HVHHF articles mentioning animals from 2012–2018 to assess how animals and human–animal relationships are discussed. Three dominant article theme classifications emerge: animal-focused articles, animal-observant articles, and animal sentinel articles. Across themes, articles seldom acknowledge the inherent value or the social and psychological importance of animals in human lives; instead, the focus is almost exclusively on the use of animals as sentinels for potential human health risks. Further, what is nearly absent from this body of literature is any social science research. Given that relationships with animals are an integral part of human existence, this study applies environmental justice principles, serving as a call to action for social science scholars to address the impacts of HVHHF on animals and human–animal relationships.
