“…in Rhinella Reports on natural and artificial hybridization are well known in many bufonids including multiple species of Rhinella (e.g., Blair, 1972;Green, 1996;Gergus et al, 1999;Malmos et al, 2001;Masta et al, 2002;Baldo and Basso, 2004;Yamazaki et al, 2008;Goebel et al, 2009;Fontenot et al, 2011;Correa et al, 2012Correa et al, , 2013Pereyra et al, 2016a;Betto-Colliard et al, 2018). Explosive breeding events with intense male competition for mates and passive female choice (i.e., scramble competition; see Wells, 2007;Pereyra et al, 2016b) is common in many species of several genera of Bufonidae, and premating isolating mechanisms seem to be insufficient to avoid interspecific amplexus in these species (see Blair, 1958;Guerra et al, 2011).…”

True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular characters, and it lacks a proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, the monophyly of some of them have been rejected in previous phylogenetic analyses, and many species remain unassigned to these poorly defined groups. Additionally, the identity and taxonomy of several species are problematic and hinder the specific recognition and description of undescribed taxa. In this work, we first perform phylogenetic analyses of separate mitochondrial and nuclear datasets to test the possible occurrence of hybridization and/or genetic introgression in the genus. The comparative analysis of both datasets revealed unidirectional mitochondrial introgressions of an unknown parental species into R . horribilis ("ghost introgression") and of R . dorbignyi into R . bernardoi; therefore, the mitochondrial and nuclear datasets of these species were considered separately in subsequent analyses. We performed total-evidence phylogenetic analyses that included revised molecular (four mitochondrial and five nuclear genes) and phenotypic (90 characters) datasets for 83 nominal species of Rhinella, plus several undescribed and problematic species and multiple outgroups. Results demonstrate that Rhinella was nonmonophyletic due to the position of R . ceratophrys, which was recovered as the sister taxon of Rhaebo nasicus with strong support. Among our outgroups, the strongly supported Anaxyrus + Incilius is the sister clade of all other species of Rhinella. Once R . ceratophrys is excluded, the genus Rhinella is monophyletic, well supported, and composed of two major clades. One of these is moderately supported and includes species of the former R . spinulosa Group (including R . gallardoi); the monophyletic R . granulosa, R . crucifer, and R . marina Groups; and a clade composed of the mitochondrial sequences of R . horribilis. The other major clade is strongly supported and composed of all the species from the non-monophyletic R . veraguensis and R . margaritifera Groups, the former R . acrolopha Group, and R . sternosignata. Consistent with these results, we define eight species groups of Rhinella that are mostly diagnosed by phenotypic synapomorphies in addition to a combination of morphological character states. Rhinella sternosignata is the only species that remains unassigned to any group. We also synonymize nine species, treat three former subspecies as full species, and suggest that 15 lineages represent putative undescribed species. Lastly, we discuss the apparently frequent occurrence of hybridization, deep mitochondrial divergence, and "ghost introgression"; the incomplete phenotypic evidence (including putative character systems that could be used for future phylogenetic...

“…La urgencia de proteger la franja costera adyacente al parque se hace más notoria al ser en esta área donde se registró exclusivamente a dos de las especies endémicas capturadas en este La variabilidad genética también es parte de la biodiversidad y respecto a algunas de las especies registradas en este estudio corresponderían a los siguientes linajes genéticos: T. elegans al linaje Aconcagua (Boric-Bargetto, 2015; Boric-Bargetto et al, en revisión), A. longipilis al linaje norte (Valdez et al, 2020), P. darwini al linaje B (Gutiérrez-Tapia & Palma, 2016), O. degus al linaje norte (Valladares, 2009), A. o. olivacea (Rodríguez-Serrano et al, 2006 y O. l. longicaudatus (Palma et al, 2012). Además, en los alrededores del sitio prioritario para la conservación Los Molles-Pichidangui se han reportado especies híbridas de plantas y animales (Correa et al, 2013;Frías, 2005;Schulte et al, 2010).…”

The conservation of biodiversity in Mediterranean Chile requires a greater coverage than that represented in the Protected Wild Areas of the State (SNASPE) and Private Protected Areas (APP) are complementary alternative for conservation. The study of biodiversity in APP is scarce, ignoring its contribution to the conservation. The small mammals assemblage of the APP Bioparque Puquén and surroundings was described comparing the species richness, relative abundance and diversity index of Margalef inside and outside the park. Using the Morisita-Horn similarity index and a cluster analysis, the small mammals assemblage was compared between sampling points categorized in different biotopes. Endemic and native species were more abundant outside the APP. There were no significant differences in specific richness or diversity inside and outside the APP. The small mammals assemblage was grouped into biotopes of dense native vegetation and prairies, ravines and seasonal waters. The park would act as buffer area, protecting the nearby areas of the Los Molles-Pichidangui Priority Site. The importance of rocky outcrops as a habitat for endemic species of small mammals and protecting the areas adjacent to the BioParque is discussed.

Han transcurrido diez años desde que se publicó la última síntesis general del estado de conocimiento de los anfi bios de Chile. Durante este periodo se han realizado numerosos aportes al conocimiento de estos organismos e implementado acciones enfocadas a su conservación. El objetivo de este trabajo es describir los avances realizados en distintas áreas científi cas y en el campo de la conservación de los anfi bios de Chile durante los últimos diez años, para obtener una visión actualizada de su estado de conocimiento y conservación e identifi car algunas áreas que requerirían un mayor esfuerzo de investigación. La actualización se basó en 155 trabajos publicados entre 2006 y 2015, que incluyen artículos científi cos de revistas ISI y no ISI, libros, capítulos de libros y guías de campo. Estas publicaciones fueron clasifi cadas por año y por área científi ca para examinar la tendencia temporal en el número de publicaciones e identifi car en qué áreas se ha concentrado la labor científi ca. Las áreas en que se realizó la mayoría de las investigaciones durante esta última década fueron conservación, distribución geográfi ca y biogeografía, etología, taxonomía, y genética y fi logeografía. Entre estas, la conservación se ha consolidado como una disciplina de interés científi co y se ha benefi ciado de acciones concretas como programas de crianza ex situ e in situ, la propuesta de un Plan Nacional de Conservación de Anfi bios, y la evaluación de los estados de conservación realizada a través del Reglamento de Clasifi cación de Especies. Finalmente, se sugieren algunas temáticas que requerirían mayor atención por parte los investigadores en las áreas de la taxonomía, sistemática, biogeografía, biología y conservación. PALABRAS CLAVE: anfi bios de Chile, conservación, investigación, recopilación bibliográfi ca.
