Extreme Miniaturization of a New Amniote Vertebrate and Insights Into the Evolution of Genital Size in Chameleons
www.nature.com/scientificreports OPEN Extreme miniaturization of a new amniote vertebrate and insights into the evolution of genital size in chameleons Frank Glaw1*, Jörn Köhler2, Oliver Hawlitschek3, Fanomezana M. Ratsoavina4, Andolalao Rakotoarison4, Mark D. Scherz5 & Miguel Vences6 Evolutionary reduction of adult body size (miniaturization) has profound consequences for organismal biology and is an important subject of evolutionary research. Based on two individuals we describe a new, extremely miniaturized chameleon, which may be the world’s smallest reptile species. The male holotype of Brookesia nana sp. nov. has a snout–vent length of 13.5 mm (total length 21.6 mm) and has large, apparently fully developed hemipenes, making it apparently the smallest mature male amniote ever recorded. The female paratype measures 19.2 mm snout–vent length (total length 28.9 mm) and a micro-CT scan revealed developing eggs in the body cavity, likewise indicating sexual maturity. The new chameleon is only known from a degraded montane rainforest in northern Madagascar and might be threatened by extinction. Molecular phylogenetic analyses place it as sister to B. karchei, the largest species in the clade of miniaturized Brookesia species, for which we resurrect Evoluticauda Angel, 1942 as subgenus name. The genetic divergence of B. nana sp. nov. is rather strong (9.9‒14.9% to all other Evoluticauda species in the 16S rRNA gene). A comparative study of genital length in Malagasy chameleons revealed a tendency for the smallest chameleons to have the relatively largest hemipenes, which might be a consequence of a reversed sexual size dimorphism with males substantially smaller than females in the smallest species. -

Quantifying the Conservation Value of Plantation Forests for a Madagascan Herpetofauna
Herpetological Conservation and Biology 14(1):269–287. Submitted: 6 March 2018; Accepted: 28 March 2019; Published: 30 April 2019. QUANTIFYING THE CONSERVATION VALUE OF PLANTATION FORESTS FOR A MADAGASCAN HERPETOFAUNA BETH EVANS Madagascar Research and Conservation Institute, Nosy Komba, Madagascar current address: 121 Heathway, Erith, Kent DA8 3LZ, UK, email: [email protected] Abstract.—Plantations are becoming a dominant component of the forest landscape of Madagascar, yet there is very little information available regarding the implications of different forms of plantation agriculture for Madagascan reptiles and amphibians. I determined the conservation value of bamboo, secondary, open-canopy plantation, and closed-canopy plantation forests for reptiles and amphibians on the island of Nosy Komba, in the Sambirano region of north-west Madagascar. Assistants and I conducted 220 Visual Encounter Surveys between 29 January 2016 and 5 July 2017 and recorded 3,113 reptiles (32 species) and 751 amphibians (nine species). Closed-canopy plantation supported levels of alpha diversity and community compositions reflective of natural forest, including several threatened and forest-specialist species. Open-canopy plantation exhibited diminished herpetofaunal diversity and a distinct community composition dominated by disturbance-resistant generalist species. Woody tree density and bamboo density were positively correlated with herpetofaunal species richness, and plantation species richness, plantation species density, sapling density, and the proportion of wood ground cover were negatively associated with herpetofaunal diversity. I recommend the integration of closed-canopy plantations on Nosy Komba, and across wider Madagascar, to help mitigate the negative effects of secondary forest conversion for agriculture on Madagascan herpetofauna; however, it will be necessary to retain areas of natural forest to act as sources of biodiversity for agroforestry plantations. -

Metodología: Se utilizó el método de relevamiento por encuentros visuales (VES); además se calculó el índice de importancia relativa, el índice de jerarquización y la diversidad trófica. Resultados: Se identificaron de acuerdo a la nomenclatura taxonómica un total de 140 individuos repartidos en dos phylum, tres clases y cinco ordenes, siendo el orden Hy- menoptera el más abundante para las dos especies; por otro lado, no se predijeron más novedades tróficas. Conclusiones: Los índices permiten inferir que las especies estudiadas consumen una amplia variedad de invertebrados, por ello estas especies pueden ser especialistas o generalistas.

Two Decades of Land Acquisition for Conservation

Since its foundation in 2001, the Land Acquisition Fund has enabled and facilitated the acquisition of over 40,000 hectares of nature, thereby creating a foundation for species to survive and thrive. For more than 100 NGOs, the fund proved to be crucial in pursuing their conservation objectives. The support provided allowed these NGOs to grow, both institutionally and in hectares under sustainable management.

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.
