Available in PDF, EPUB and Kindle. Book excerpt: Covering diverse species from garter snakes to Komodo dragons, this book delves into the evolutionary origins and fascinating details of the mysterious social lives of reptiles. Reptiles have been too often dismissed as dull animals with tiny brains and simple, "asocial" lives. In reality, reptiles engage in a remarkable diversity of complex social behavior. They can live in families; communicate with one another while still in the egg; and hunt, feed, migrate, court, mate, nest, and hatch in groups. In The Secret Social Lives of Reptiles, J. Sean Doody, Vladimir Dinets, and Gordon M. Burghardt—three of the world's leading experts on reptiles—bring together a wave of new research with a synthesis of classic studies to produce the only authoritative look at the social behaviors of the most provocative animals on the planet. The book covers turtles, lizards, snakes, crocodilians, and the enigmatic tuatara. Enhanced with dozens of images, it takes readers through a myriad of social interactions, tendencies, and intimacies ranging from fierce territorial battles to delicate paternal care and from promiscuous pairings to monogamous partnerships. This unique text • explains why reptiles have been neglected as subjects of social behavior studies; • provides numerous examples across all major reptilian groups that overturn the false paradigm of "solitary" reptiles; • explores the sensory, genetic, physiological, life history, and other factors underlying social behavior in reptiles; • presents the case that evolutionary "experiments" found among reptiles offer unparalleled opportunities for understanding how and why social behavior evolves in animals; and • identifies new and developing areas of research helping to reshape our view of reptiles. Revealing the secrets of reptilian social relationships through original quantitative research, field studies, laboratory experiments, and careful analysis of the literature, The Secret Social Lives of Reptiles elevates these fascinating animals to key players in the science of behavioral ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Long-term ecological data are critical for informing long-term trends in biodiversity and trends in environmental change. The Terrestrial Ecosystem Research Network (TERN) is a major initiative of the Australian Government and one of its key areas of investment is to provide funding for a network of long-term ecological research plots around Australia (LTERN). This book highlights some of the temporal changes in the environment and/or in biodiversity that have occurred in different ecosystems, ranging from tropical rainforests, wet eucalypt forests and alpine regions through to rangelands and deserts. Many important trends and changes are documented and they often provide new insights that were previously poorly understood or unknown. These data are precisely the kinds of data so desperately needed to better quantify the temporal trajectories in the environment and biodiversity in Australia.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasites make up a large part of the world's biodiversity and are important components of ecosystems because they influence the fitness of their hosts, and therefore intraspecific and interspecific interactions. Historically, parasites have often been overlooked in ecological studies, so there are gaps in our understanding of their natural history, and even fundamental information, such as their geographic distribution, is often poorly understood. The distribution of parasites is not consistent throughout their distribution range. Variations in limiting factors, such as precipitation, in an area can influence plant communities in such a way that it creates ecological gradients. Species that can inhabit a variety of habitat types often occur throughout such an ecological gradient. However, the parasites that infect them may differ over the ecological gradient due to being more habitat specific or requiring additional hosts that are habitat specific. -- In this thesis, I explored parasite community variations in a sleepy lizard (Tiliqua rugosa) population inhabiting an area with a precipitation-induced ecological gradient, and whether different plant communities from natural vegetation to those more affected by farming can influence these parasite communities. This work is a continuation of a long-established area of exploration of sleepy lizards and their parasites set up by the late Prof. C. Michael Bull who built upon the earlier work by Michael Smyth. -- Through the dissection of road kills I confirmed the gastrointestinal helminths that infect lizards in the study site. I caught lizards along established transects in the study site and examined them for the presence of ectoparasites. I also collected blood and faecal samples that were subsequently examined microscopically to determine the prevalence of the various endoparasites in the sleepy lizard population. -- Vegetation data were collected from sample plots along two transects that span both disturbed and rehabilitated areas and are therefore representative of the vegetation of the study site. The floristic data was analysed to determine the various plant communities. Based on the identified plant communities, the habitats along the two transects were assigned to different habitat categories. -- The geographic distribution of the various identified ecto- and endoparasites were then mapped out within the study site. Sub-samples of the data collected along the two transects used for the vegetation studies were used to identify associations between different parasite species and various habitat categories. -- This work has furthered our knowledge on associations between the parasite community of sleepy lizards and different habitats. The variations in the parasite community were mainly driven by differences in the prevalence of ixodid tick species as a result of their association with specific habitat categories. Precipitation as well as disturbances to the habitat influenced the distribution of these ectoparasites, which influences the degree of overlap in their parapatric distribution. The information about the prevalence of the various parasites across the ecological gradient form a basis for future studies, which should focus on filling the gaps in our understanding of the life cycles the parasites, and identifying the ecological roles they play.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Broadly, this work attempts to integrate host personality (i.e., consistent individual differences in behavior) and parasitism using a wild population of sleepy lizards (Tiliqua rugosa) and their tick parasites. To that end, Chapter 1 first studies personality in sleepy lizards over a six-year period. Specifically, we evaluated the factors that influenced lizard aggression and boldness scores, as well as determined whether these behaviors constituted personality (via quantifying their repeatability). We found a positive relationship between tick counts and lizard aggression and boldness. Both of these behaviors were also repeatable (i.e., differed consistently among individuals) for males and females through long periods, even across years. Next, given that we know that individuals of many species often differ in their parasite loads and consistently differ in their behavior, Chapter 2 uses nine years of tick count data to investigate whether sleepy lizards differed consistently in their parasitism. We found that lizards did indeed differ, such that some individuals persistently had more ticks while others had fewer. These consistent differences endured both within and across years. Lizard aggression and boldness, intriguingly, were not strongly associated with lizard average tick counts. Chapter 3 then examines more explicitly the connections between lizard personality and infection using an experimental infestation of lizards. We correlated pre-treatment behavior with the success of the infestation (attachment probability), and we assessed the effect of infestation on behavior post-treatment. Interestingly, lizard aggression and boldness interactively related to attachment probability: Increasing boldness was associated with reduced infestation success for less aggressive lizards, but greater infestation for more aggressive lizards. Upon infestation, lizards became bolder, but aggression did not change. These results therefore present the possibility of host behavior-parasite feedbacks that depend on multiple behaviors (i.e., the direction of the feedback depends on both aggression and boldness). Lastly, using piecewise structural equation modeling, Chapter 4 tests how lizard personality related to tick exposure and acquisition via intermediary pathways. For example, lizards predominantly acquire ticks through shared refuge use (which must occur with a time lag), so we considered how aggression and boldness affected refuge use, and then how refuge use affected tick counts. We found, surprisingly, that aggression and boldness did not affect tick counts either directly or through intermediary pathways. However, lizard behaviors still mattered. Tick acquisition, for instance, strongly increased with lizards' time-lagged refuge sharing, which itself increased with lizards' social network interactivity. Together, these chapters present a few key findings: 1) both behavior and parasitism can differ consistently among individuals (e.g., individuals may exhibit both persistently high aggression and parasite loads); 2) behavior and parasites obviously interconnect, but the feedbacks between behavior and parasitism may involve multiple distinct behaviors, the combination of which may affect the direction of the parasite-behavior feedback; and 3) though host behavior can strongly affect parasite transmission, only certain behaviors may matter, and some of these behaviors may act indirectly. Considering direct and indirect links among multiple behaviors and parasites, as well as whether such traits differ consistently among individuals in wild conditions, may greatly enhance our understanding of host-parasite ecology.
