  • Predation Upon Mantella Aurantiaca in the Torotorofotsy Wetlands, Central-Eastern Madagascar
    Herpetology Notes, volume 2: 95-97 (2009) (published online on 10 July 2009) Predation upon Mantella aurantiaca in the Torotorofotsy wetlands, central-eastern Madagascar Olga Jovanovic1*, Miguel Vences1, Goran Safarek2, Falitiana C.E. Rabemananjara3, Rainer Dolch4 Abstract. Malagasy poisonous frogs of genus Mantella are small, diurnal frogs with skin glands containing alkaloids and characterised by aposematic colouration. Due to their noxiousness and warning colouration, it is thought that they do not have many natural predators. Until now, only one successful and one aborted predation on Mantella frogs were reported. Herein, we account about two successful predations on M. aurantiaca in Torotorofotsy wetland, in central-eastern Madagascar. The first predation was observed by lizard Zoonosaurus sp. and the second predation by a snake probably belonging to Thamnosophis lateralis. Both predators did not seem to mind the taste of the M. aurantiaca and ingested it. Keywords. Amphibia: Mantellidae, poison frogs, Thamnosophis, Zoonosaurus Only little is known about predation on poisonous genus Melanophryniscus of southeastern South America, frogs in general, in particular for those containing in Malagasy poison frogs of the genus Mantella (family skin alkaloids.

Patterns of reproductive-mode evolution in doi:10.1111/zsc.12121 Old World tree frogs (Anura, Rhacophoridae). —Zoologica Scripta, 00, 000–000. The Old World tree frogs (Anura: Rhacophoridae), with 387 species, display a remarkable diversity of reproductive modes – aquatic breeding, terrestrial gel nesting, terrestrial foam nesting and terrestrial direct development. The evolution of these modes has until now remained poorly studied in the context of recent phylogenies for the clade. Here, we use newly obtained DNA sequences from three nuclear and two mitochondrial gene fragments, together with previously published sequence data, to generate a well-resolved phylogeny from which we determine major patterns of reproductive-mode evolution. We show that basal rhacophorids have fully aquatic eggs and larvae. Bayesian ancestral-state reconstruc- tions suggest that terrestrial gel-encapsulated eggs, with early stages of larval development completed within the egg outside of water, are an intermediate stage in the evolution of ter- restrial direct development and foam nesting. The ancestral forms of almost all currently recognized genera (except the fully aquatic basal forms) have a high likelihood of being ter- restrial gel nesters. Direct development and foam nesting each appear to have evolved at least twice within Rhacophoridae, suggesting that reproductive modes are labile and may arise multiple times independently.

  • Congolius, a New Genus of African Reed Frog Endemic to The
    www.nature.com/scientificreports OPEN Congolius, a new genus of African reed frog endemic to the central Congo: A potential case of convergent evolution Tadeáš Nečas1,2*, Gabriel Badjedjea3, Michal Vopálenský4 & Václav Gvoždík1,5* The reed frog genus Hyperolius (Afrobatrachia, Hyperoliidae) is a speciose genus containing over 140 species of mostly small to medium-sized frogs distributed in sub-Saharan Africa. Its high level of colour polymorphism, together with in anurans relatively rare sexual dichromatism, make systematic studies more difcult. As a result, the knowledge of the diversity and taxonomy of this genus is still limited. Hyperolius robustus known only from a handful of localities in rain forests of the central Congo Basin is one of the least known species. Here, we have used molecular methods for the frst time to study the phylogenetic position of this taxon, accompanied by an analysis of phenotype based on external (morphometric) and internal (osteological) morphological characters. Our phylogenetic results undoubtedly placed H. robustus out of Hyperolius into a common clade with sympatric Cryptothylax and West African Morerella. To prevent the uncovered paraphyly, we place H. robustus into a new genus, Congolius. The review of all available data suggests that the new genus is endemic to the central Congolian lowland rain forests. The analysis of phenotype underlined morphological similarity of the new genus to some Hyperolius species. This uniformity of body shape (including cranial shape) indicates that the two genera have either retained ancestral morphology or evolved through convergent evolution under similar ecological pressures in the African rain forests. African reed frogs, Hyperoliidae Laurent, 1943, are presently encompassing almost 230 species in 17 genera.

    TOWN OF JUPITER DATE: November 19, 2019 TO: Honorable Mayor and Members of Town Council THRU: Matt Benoit, Town Manager FROM: David Brown, Utilities Director MB John R. Sickler, Director of Planning and Zoning SUBJECT: Glyphosate Use Reduction –Resolution to call for a reduction in the use of products containing glyphosate by the Town and its contractors and encouraging a reduction in use by the public HEARING DATES: ETF 11/4/19 PZ #19-4030 TC 11/19/19 Resolution #108-19 EXECUTIVE SUMMARY: Consideration of a resolution recognizing the potential human health and environmental benefits of reducing the use of glyphosate-based herbicides by Town employees and its contractors. Background While glyphosate and formulations such as Roundup have been approved by regulatory bodies worldwide, concerns about their effects on humans and the environment persist, and have grown as the global usage of glyphosate increases. There is a growing belief by some that glyphosate may be carcinogenic. Much of this concern is related to use on food crops and direct exposure via application of the herbicide. In 2015, glyphosate was classified as a probable carcinogen by the International Agency for Research on Cancer, an arm of the World Health Organization (Attachment A). However, this designation was not without controversy (Attachment B) and it is important to note that the U.S. Environmental Protection Agency (EPA) maintains that glyphosate is not likely to be carcinogenic to humans and is not currently banned for use by the U.S. government (pg. 143, Attachment C). In addition, the University of Florida Institute of Food and Agricultural Sciences continues to recommend the use of glyphosate as a weed control tool with the caveat that users of these products must carefully read and follow all label directions (Attachment D).

  • 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.

Opening of the meeting The Chair opened the meeting and welcomed all participants, before giving the floor to the Secretary- General, who also welcomed everyone and introduced new members of the Secretariat's scientific team (Mr De Meulenaer and Ms Kwitsinskaia) and enforcement team (Ms Garcia Ferreira, Ms Jonsson and Mr van Rensburg). He wished the Committee well in its deliberations. The Chair thanked the Secretary-General and invited suggestions as to how the Conference of the Parties could establish stronger measures to support the Committee as well as export countries, which deserved particular assistance. No other intervention was made during discussion of this item.1 2. Rules of Procedure The Secretariat introduced document AC26 Doc. 2 and proposed amending Rule 22 as follows: “On request, the Secretariat shall distribute printed and translated documents...”. The Secretariat explained that most members regularly indicated that they did not need printed copies and that this proposal was made to reduce costs. Although not opposed to the change in principle, a Party regretted that the suggestion had not been presented in the document, which would have given Parties time to consider it, and was concerned that this unannounced proposal might create a precedent. Another Party asked a question on the procedure to accept observers, but the Chair invited it to raise this topic under agenda item 4 on Admission of observers.
