Abstract. Diversity at 35 allozyme loci was examined in nine populations of the taxa currently included in Darevskia saxicola . The data support the recognition of the subspecies Darevskia s. saxicola and D. s. lindholmi as species. The remaining subspecies D. s. brauneri, D. s. darevskii and D. s. szczerbaki are conspeciŽ c although they can no longer be referred to Darevskia saxicola , but mu...

Knowing whether triploid hybrids resulting from natural hybridization of parthenogenetic and bisexual species are fertile is crucial for understanding the mechanisms of reticulate evolution in rock lizards. Here, using males of the bisexual diploid rock lizard species Darevskia raddei nairensis and Darevskia valentini and a triploid hybrid male Darevskia unisexualis × Darevskia valentini, we pe...

A broad sample of Darevskia rudis from the main part of its range was reviewed with regard to external morphology (discriminant, UPGMA, MST and ANOVA analyses) and osteology. Darevskia bithynica is raised to species rank, with two subspecies: D. b. bithynica and D. b. tristis. The other subspecies are fairly similar (D. r. rudis being the most different). Two singular populations are described ...

Satellite DNA repeats were studied in Caucasian populations of 18 rock lizard species of the genus Darevskia. Four subfamilies (Caucasian Lacerta satellites (CLsat)I-IV) were identified, which shared 70%-75% sequence similarity. The distribution of CLsat subfamilies among the species was studied. All the species could be divided into at least 3 clades, depending on the content of CLsat subfamil...

A Base Nacional Comum Curricular (BNCC), define as aprendizagens essenciais que os estudantes devem desenvolver em diferentes etapas da educação básica. No texto não há definição específica sobre a linha metodológica utilizada. Piaget, através epistemologia genética, definiu como se dá o conhecimento na criança. Constance Kamii aplicou teoria de Piaget experimentações com alunos e professores d...

Esse estudo, bibliográfico e documental, se propõe apresentar parte da trajetória de Constance Kamii, renomada cientista, colaboradora Jean Piaget, suas obras publicações no Brasil. Tomando por referência a construção do conhecimento, Kamii dedicou-se à educação escolar, realizando investigações teórico-práticas com implicações partir teoria piagetiana. Estudava profundamente obra Piaget trabal...
