Gibbs Thesis Final Revised Final
Species Declines: Examining patterns of species distribution, abundance, variability and conservation status in relation to anthropogenic activities Mary Katherine Elizabeth Gibbs Thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the PhD degree in the Ottawa-Carleton Institute of Biology Thèse soumise à la Faculté des étude supérieures et postdoctorales Université d’Ottawa en vue de l’obtention du doctorat de L’institut de biologie d’Ottawa-Carleton Department of Biology Faculty of Science University of Ottawa © Mary Katherine Elizabeth Gibbs, Ottawa, Canada, 2012 Acknowledgements First and foremost, I would like to thank my supervisor, Dr. David Currie. Most importantly, you gave me the freedom to work on questions that I’m passionate about. You never stopped challenging me and always asked that I push a little bit farther. I really think your commitment to scientific rigor goes above and beyond the average. And thank you for the many, many cups of tea over the years. My committee members, Dr. Scott Findlay and Dr. Mark Forbes, your feedback made this a better thesis. Scott, thank you for being scary enough to motivate me to always bring my A-game, and for providing endless new words to look up in the dictionary. By the end of this, I may actually know what ‘epistemological’ means. I would also like to thank Dr. Jeremy Kerr for his insight and not being afraid to be a scientist and an advocate. I need to thank all the lab mates that have come and gone and added so much to the last six years. -

We became minded to look at this one – the fight between steak and sizzle – following a series of comments from prospective new clients with a desire to do some ‘easy’ ‘innovation stuff’. Our initial response to the queries was, ‘sorry, we can’t help you’ (there is nothing quite so liberating as saying ‘no’ to someone!). Upon reflection, it provoked us to start re-using our old ‘innovation is hard, dummy’ aphorism. Another couple of weeks of incubation and we’re now left with the thoughts presented here. A really good way of presenting these kinds of high level contradiction is through the classic 2x2 management matrix. -
A New Species of Amolops from Thailand (Amphibia, Anura, Ranidae)

Amolops panhai, new species, differs from its congeners by the combination of: small body, males 31–34 mm, females 48–58 mm in snout-vent length; head narrower than long; tympanum distinct; vomerine teeth in short, oblique patches; first finger subequal to second; disc of first finger smaller than that of second, with circummarginal groove; no wide fringe of skin on third finger; toes fully webbed; outer metatarsal tubercle present; supratympanic fold present; dor- solateral fold indistinct; axillary gland present; horny spines on back, side of head and body, and chest absent; large tubercles on side of anus absent; glandular fold on ventral surface of tarsus absent; nuptial pad and paired gular pouches present in male; white band along the upper jaw extending to shoulder absent; larval dental formula 7(4-7)/3(1). This new species is the second anu- ran discovered which has a disjunct distribution around the Isthmus of Kra.

We have enlisted 10 very eager and capable volunteers, who are currently drafting as- sessments, based on the data in previously-published species accounts. Once the draft assessments have been made, using all available data, we will then ask the appropriate species experts to review the drafts, update any additional data, and then approve them. This process of pre-filling assessments has been used for amphibian assessments in the IUCN Red List, and has proven to be very beneficial. © Gilbert Alvarado Barboza © Alvarado Gilbert Our Training Officer is planning for a couple of capacity- During the past two months Amphibian Ark has been building courses in the coming months - the Biology, involved in a number of projects.

These nutrients are essential for fulfilling the energy requirements of the animal cells. The nutrients produce energy when they undergo oxidation during the process of respiratory metabolism. The end products generated by oxidation are energy, water, and carbon dioxide. Thus vertebrates consume oxygen for oxidation of nutrients present within the cells. This oxygen needs to be replenished and the waste byproducts like heat and carbon dioxide produced during oxidation metabolism must be removed in order to survive. The sequence of events that result in exchange of oxygen and carbon dioxide between an organism and its environment is known as respiration. This is done primarily by the respiratory system. The gas exchange between the environment and blood via the respiratory surface is referred to as external respiration. The utilization of oxygen for oxidation of nutrients within the cells and tissues may be termed as internal respiration. -
The Occurrence of Batrachochytrium Dendrobatidis in Brazil and the Inclusion of 17 New Cases of Infection

Recently, six species have been reported to be infected by chytridiomycosis in Brazil, presenting a wide range of distribution, of about 2,400 km over the Atlantic Forest. However, in a country such as Brazil, information about this disease is still beginning to accumulate. Based on morphological and histological data, we found evidence of B. dendrobatidis infection in 16 Brazilian anuran species, members of the families Cycloramphidae and Hylidae. We analyzed tadpoles lacking teeth that were collected from 1964 to 2005, to seek for chytridiomycosis. Our results extend the distribution of the fungus in Brazil ca. 630 km southward (straight-line distance), reaching the southernmost limits of the Atlantic rainforest. We also speculate about its distribution in the Cerrado and Pantanal.

A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance
Chapter 21 A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance Juan C. Santos , Rebecca D. Tarvin , and Lauren A. O’Connell 21.1 Introduction Chemical defense has evolved multiple times in nearly every major group of life, from snakes and insects to bacteria and plants (Mebs 2002 ). However, among land vertebrates, chemical defenses are restricted to a few monophyletic groups (i.e., clades). Most of these are amphibians and snakes, but a few rare origins (e.g., Pitohui birds) have stimulated research on acquired chemical defenses (Dumbacher et al. 1992 ). Selective pressures that lead to defense are usually associated with an organ- ism’s limited ability to escape predation or conspicuous behaviors and phenotypes that increase detectability by predators (e.g., diurnality or mating calls) (Speed and Ruxton 2005 ). Defended organisms frequently evolve warning signals to advertise their defense, a phenomenon known as aposematism (Mappes et al. 2005 ). Warning signals such as conspicuous coloration unambiguously inform predators that there will be a substantial cost if they proceed with attack or consumption of the defended prey (Mappes et al. 2005 ). However, aposematism is likely more complex than the simple pairing of signal and defense, encompassing a series of traits (i.e., the apose- matic syndrome) that alter morphology, physiology, and behavior (Mappes and J.
