What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
Paul McGreevy, PhD
We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.
Farm Animals Are Not Humans In Sheep Clothing, Lorenz Gygax, Christian Nawroth
Farm Animals Are Not Humans In Sheep Clothing, Lorenz Gygax, Christian Nawroth
Christian Nawroth, PhD
Research on the mental lives of farm animals is crucial to assess not only their physical but also their psychological wellbeing. Their current housing and handling practices are highly unlikely to meet their cognitive needs and demands, but our knowledge of their mental capacities is still limited. Although folk wisdom often refers to farm animals as dull and inflexible, recent studies show they have a rich interpretation of their environment and can solve complex problems. Yet an uncritical and anthropomorphic assessment of farm animal cognition and behaviour may lead to the attribution of an exaggerated amount of cognitive flexibility. Contrary …

The Dry Season Shuffle: Gorges Provide Refugia For Animal Communities In Tropical Savannah Ecosystems, J. Sean Doody, Simon Clulow, Geoff Kay, Domenic D'Amore, David Rhind, Steve Wilson, Ryan Ellis, Christina Castellano, Colin Mchenry, Michelle Quayle, Kim Hands, Graeme Sawyer, Michael Bass

In the wet-dry tropics, animal species face the major challenges of acquiring food, water or shelter during an extended dry season. Although large and conspicuous animals such as ungulates and waterfowl migrate to wetter areas during this time, little is known of how smaller and more cryptic animal species with less mobility meet these challenges. We fenced off the entire entrance of a gorge in the Australian tropical savanna, offering the unique opportunity to determine the composition and seasonal movement patterns of the small vertebrate community. The 1.7 km-long fence was converted to a trapline that was deployed for 18-21 …

Novel Habitat Causes A Shift To Diurnal Activity In A Nocturnal Species, J. Sean Doody, Colin R. Mchenry, David Rhind, Simon Clulow
Novel Habitat Causes A Shift To Diurnal Activity In A Nocturnal Species, J. Sean Doody, Colin R. Mchenry, David Rhind, Simon Clulow
J. Sean Doody
Plastic responses may allow individuals to survive and reproduce in novel environments, and can facilitate the establishment of viable populations. But can novel environments reveal plasticity by causing a shift in a behavior as fundamental and conspicuous as daily activity? We studied daily activity times near the invasion front of the cane toad (Rhinella marina), an invasive species that has colonized much of northern Australia. Cane toads in Australia are nocturnal, probably because diurnal activity would subject them to intolerably hot and dry conditions in the tropical savannah during the dry season. Our study can demonstrate, however, that upon reaching …
Conceptual Model For Thermal Limits On The Distribution Of Reptiles, J. Sean Doody, Jennifer A. Moore
Conceptual Model For Thermal Limits On The Distribution Of Reptiles, J. Sean Doody, Jennifer A. Moore
J. Sean Doody
Recent climate change has re-invigorated scientific interest in the dynamics of geographic distributions of organisms. Climate responses and their biogeographical ramifications can be predicted indirectly by studying variation in fitness-related traits across environmental gradients in wide-ranging species. We review evidence for such variation in reptiles. Clinal variation in seasonal timing (onset) of nesting is common but may offer only minor compensation. In contrast, clinal variation in nesting behavior in two wide-ranging species suggests that reptiles can use nest site choice to counter climate differences. We suggest that when range boundaries located at climate extremes are determined by thermal conditions of …
Claw Morphometrics In Monitor Lizards: Variable Substrate And Habitat Use Correlate To Shape Diversity Within A Predator Guild, Domenic C. D'Amore, Simon Clulow, J. Sean Doody, David Rhind, Colin R. Mchenry
Claw Morphometrics In Monitor Lizards: Variable Substrate And Habitat Use Correlate To Shape Diversity Within A Predator Guild, Domenic C. D'Amore, Simon Clulow, J. Sean Doody, David Rhind, Colin R. Mchenry
J. Sean Doody
Numerous studies investigate morphology in the context of habitat, and lizards have received particular attention. Substrate usage is often reflected in the morphology of characters associated with locomotion, and, as a result, claws have become well-studied ecomorphological traits linking the two. The Kimberley predator guild of Western Australia consists of 10 sympatric varanid species. The purpose of this study was to quantify claw size and shape in the guild using geometric morphometrics, and determine whether these features correlated with substrate use and habitat. Each species was assigned a Habitat/substrate group based on the substrate their claws interact with in their …
Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari
Alice Fornari
Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as more collections …
