  • Predators As Agents of Selection and Diversification
    diversity Review Predators as Agents of Selection and Diversification Jerald B. Johnson * and Mark C. Belk Evolutionary Ecology Laboratories, Department of Biology, Brigham Young University, Provo, UT 84602, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-801-422-4502 Received: 6 October 2020; Accepted: 29 October 2020; Published: 31 October 2020 Abstract: Predation is ubiquitous in nature and can be an important component of both ecological and evolutionary interactions. One of the most striking features of predators is how often they cause evolutionary diversification in natural systems. Here, we review several ways that this can occur, exploring empirical evidence and suggesting promising areas for future work. We also introduce several papers recently accepted in Diversity that demonstrate just how important and varied predation can be as an agent of natural selection. We conclude that there is still much to be done in this field, especially in areas where multiple predator species prey upon common prey, in certain taxonomic groups where we still know very little, and in an overall effort to actually quantify mortality rates and the strength of natural selection in the wild. Keywords: adaptation; mortality rates; natural selection; predation; prey 1. Introduction In the history of life, a key evolutionary innovation was the ability of some organisms to acquire energy and nutrients by killing and consuming other organisms [1–3]. This phenomenon of predation has evolved independently, multiple times across all known major lineages of life, both extinct and extant [1,2,4]. Quite simply, predators are ubiquitous agents of natural selection. Not surprisingly, prey species have evolved a variety of traits to avoid predation, including traits to avoid detection [4–6], to escape from predators [4,7], to withstand harm from attack [4], to deter predators [4,8], and to confuse or deceive predators [4,8].

  • Guidelines for Keeping Venomous Snakes in the NT
    GUIDELINES FOR KEEPING VENOMOUS SNAKES IN THE NT Venomous snakes are potentially dangerous to humans, and for this reason extreme caution must be exercised when keeping or handling them in captivity. Prospective venomous snake owners should be well informed about the needs and requirements for keeping these animals in captivity. Permits The keeping of protected wildlife in the Northern Territory is regulated by a permit system under the Territory Parks and Wildlife Conservation Act 2006 (TPWC Act). Conditions are included on permits, and the Parks and Wildlife Commission of the Northern Territory (“PWCNT”) may issue infringement notices or cancel permits if conditions are breached. A Permit to Keep Protected Wildlife enables people to legally possess native vertebrate animals in captivity in the Northern Territory. The permit system assists the PWCNT to monitor wildlife kept in captivity and to detect any illegal activities associated with the keeping of, and trade in, native wildlife. Venomous snakes are protected throughout the Northern Territory and may not be removed from the wild without the appropriate licences and permits. People are required to hold a Keep Permit (Category 1–3) to legally keep venomous snakes in the Northern Territory. Premises will be inspected by PWCNT staff to evaluate their suitability prior to any Keep Permit (Category 1– 3) being granted. Approvals may also be required from local councils, the Northern Territory Planning Authority, and the Department of Health and Community Services. Consignment of venomous snakes between the Northern Territory and other States and Territories can only be undertaken with an appropriate import / export permit. There are three categories of venomous snake permitted to be kept in captivity in the Northern Territory: Keep Permit (Category 1) – Mildly Dangerous Venomous Keep Permit (Category 2) – Dangerous Venomous Keep Permit (Category 3) – Highly Dangerous Venomous Venomous snakes must be obtained from a legal source (i.e.

    Action Statement FloraFlora and and Fauna Fauna Guarantee Guarantee Act Act 1988 1988 No. No. ### 108 Hooded Scaly-foot Pygopus nigriceps Description and Distribution The Hooded Scaly-foot Pygopus nigriceps belongs to the reptile family Pygopodidae, the legless or flap-footed lizards. Legless lizards are superficially snake-like; they lack forelimbs, and the hind limbs are reduced to a scaly flap just above the vent. Whilst their eyes are lidless and snake-like, there are several features that distinguish legless lizards from snakes. Most legless lizards have an obvious ear aperture, lacking in all snakes, and a broad fleshy tongue, compared to the deeply forked tongue of snakes. Most legless lizards also have a tail that, when unbroken, is considerably longer than their body. In contrast, the tail of snakes is considerably Hooded Scaly-foot, Pygopus nigriceps shorter than their body. The genus Pygopus Illustration by Peter Robertson Wildlife Profiles P/L © differs from other legless lizards on the basis of the combination of the following features: head covered with enlarged, symmetrical scales; smooth (compared to keeled) ventral scales; and the possession of eight or more preanal pores. Two species of Pygopus occur in Victoria. The Hooded Scaly-foot is a large legless lizard, attaining a total length of 475mm, and a snout- vent length of about 180mm. Females reach larger sizes than males. Variable in colour, the Hooded Scaly-foot may be pale grey to reddish-brown on the dorsal surface and whitish on the ventral surface. The dorsal scales may be dark-edged, forming a reticulated pattern, or individual pale and dark scales may form a vague longitudinal pattern.

  • Does Mutual Sexual Selection Explain the Evolution of Head Crests in Pterosaurs and Dinosaurs?
    LETHAIA REVIEW Does mutual sexual selection explain the evolution of head crests in pterosaurs and dinosaurs? DAVID W.E. HONE, DARREN NAISH AND INNES C. CUTHILL Hone, D.W.E., Naish, D. & Cuthill, I.C. 2011: Does mutual sexual selection explain the evolution of head crests in pterosaurs and dinosaurs? Lethaia, DOI: 10.1111/j.1502- 3931.2011.00300.x Cranial ornamentation is widespread throughout the extinct non-avialian Ornithodira, being present throughout Pterosauria, Ornithischia and Saurischia. Ornaments take many forms, and can be composed of at least a dozen different skull bones, indicating multiple origins. Many of these crests serve no clear survival function and it has been suggested that their primary use was for species recognition or sexual display. The distribution within Ornithodira and the form and position of these crests suggest sexual selection as a key factor, although the role of the latter has often been rejected on the grounds of an apparent lack of sexual dimorphism in many species. Surprisingly, the phenomenon of mutual sexual selection – where both males and females are ornamented and both select mates – has been ignored in research on fossil ornithodirans, despite a rich history of research and frequent expression in modern birds. Here, we review the available evidence for the functions of ornithodiran cranial crests and conclude that mutual sexual selection presents a valid hypothesis for their presence and distribution. The integration of mutual sexual selection into future studies is critical to our under- standing of ornithodiran ecology, evolution and particularly questions regarding sexual dimorphism. h Behaviour, Dinosauria, ornaments, Pterosauria, sexual selection.

  • Synanthropic Spiders, Including the Global Invasive Noble False Widow
    www.nature.com/scientificreports OPEN Synanthropic spiders, including the global invasive noble false widow Steatoda nobilis, are reservoirs for medically important and antibiotic resistant bacteria John P. Dunbar1,5*, Neyaz A. Khan2,5, Cathy L. Abberton3, Pearce Brosnan3, Jennifer Murphy3, Sam Afoullouss4, Vincent O’Flaherty2,3, Michel M. Dugon1 & Aoife Boyd2 The false widow spider Steatoda nobilis is associated with bites which develop bacterial infections that are sometimes unresponsive to antibiotics. These could be secondary infections derived from opportunistic bacteria on the skin or infections directly vectored by the spider. In this study, we investigated whether it is plausible for S. nobilis and other synanthropic European spiders to vector bacteria during a bite, by seeking to identify bacteria with pathogenic potential on the spiders. 11 genera of bacteria were identifed through 16S rRNA sequencing from the body surfaces and chelicerae of S. nobilis, and two native spiders: Amaurobius similis and Eratigena atrica. Out of 22 bacterial species isolated from S. nobilis, 12 were related to human pathogenicity among which Staphylococcus epidermidis, Kluyvera intermedia, Rothia mucilaginosa and Pseudomonas putida are recognized as class 2 pathogens. The isolates varied in their antibiotic susceptibility: Pseudomonas putida, Staphylococcus capitis and Staphylococcus edaphicus showed the highest extent of resistance, to three antibiotics in total. On the other hand, all bacteria recovered from S. nobilis were susceptible to ciprofoxacin. Our study demonstrates that S. nobilis does carry opportunistic pathogenic bacteria on its body surfaces and chelicerae. Therefore, some post-bite infections could be the result of vector- borne bacterial zoonoses that may be antibiotic resistant. Bacterial infections represent a major threat to human health.

  • Chapter 22 Evolutionary Biology: the Next 150 Years
    Chapter 22 hill Evolutionary Biology: I 11.11 I~ i The Next 150 Years 1, Hopi E. Hoekstra Darwin was arguably the most prescient thinker that biology has ever wit­ nessed. But, if someone had asked him in 1859 where evolutionary biology would be in 150 years, would he have guessed correctly? He might have predicted that we would have a better understanding of how traits are in­ herited-a prediction borne nut almost 30 years later with the rediscovery of Mendel's laws in 1900. Darwin considered the Jack of understanding for how traits are inherited to be the missing link in his argument fnr evolution I by natural selection, and when pushed, he devised his own theory (i.e., ~jl !I pangenesis), which was one of his few major errors. Yet, the ramifications .I of Mendel's experiments or of subsequent discoveries, like that of the three­ dimensionaJ DNA structure by Watson and Crick (1953) a century after Tlzc Origin of Species was published, along with the resultant technological advances, such as the ability to sequence a complete genome in another 50 years, were unknowable in his day. \Jor could Darwin have anticipated the questions that have dominated the field since, such as the relative role of drift and selection in driving molecular evolution (Kimura 1968). With the acknowledgement that technologies, discoveril'S, and questions will arise that, likewise, ca1mnt be imagined, it is useful-perhaps even stimulating­ to speculate about what the next 150 (or more modestly, 50 or even 20) years will hold for evolutionary biology.

  • Chancellor Mr Robyn Williams AM Is One of the Most Influential Science Journalists and Broadcasters in the English-Speaking Worl
    Chancellor Mr Robyn Williams AM is one of the most influential science journalists and broadcasters in the English-speaking world, and is among the most reliable friends and defenders of Australian science. He is best-known as host of the Science Show on ABC Radio National, which he launched in 1975. With more than 2000 episodes, it is one of the world’s longest-running programs of its type. Through this and other avenues he has done a great deal to democratise the understanding and appreciation of science. Masterfully, he brings complex work out of the pages of peer- reviewed journals and the proceedings of conferences, and into the minds of a vast and diverse audience - from school children to Nobel laureates. His topic selections and astute questions reflect his education in science, his voracious reading of journals, and his links with scientists across the globe. Born in England and schooled there and in Austria, he gained a Bachelor of Science with Honours from the University of London. Moving to Australia in the early 1970s, he earned his broadcasting stripes in the ABC Science Unit, before starting and anchoring the Science Show. Its hour-long weekly format has stood the test of time - as has its host. For 42 years, undeterred even by a period of serious illness, Mr Williams has relentlessly researched, edited, curated and interviewed. Along with the Science Show he presents Ockham’s Razor (described as a ‘soap box for all things scientific), and he has published 10 books. While countless people have benefitted from his services to science and the media, his contributions have been valued particularly at The University of Queensland.
