Resumo: Ameiva ameiva is a lizard species widely distributed in Central and South America. In this study, we present data on clutch size and duration of reproductive cycle in a population of A. ameiva from a Caatinga site in northeastern Brazil, looking to answer the following questions: 1) What is the average clutch size in this population? 2) Is clutch size associated with body size of females? 3) Is reproduction continuous or seasonal? The fieldwork to collect the lizards consisted of monthly trips from October 2008 to September 2010. Additionally, from June 2009 to May 2010, we registered the abundance of hatchlings and adults in the population by counting active lizards in the field. We collected 15 adult females, ten of which were in reproductive condition. Average clutch size was 5.3 ± 0.7 (range: 2–8, N = 10), and was significantly associated with body size of females. Reproductive females were registered both in the rainy and dry seasons, suggesting a prolonged reproductive period throughout the year. However, the decline in adult abundance during the peak of dry season and the absence of hatchlings in the population during four consecutive months are indications that females did not reproduce continuously during 2009-2010.Keywords: Clutch size; Life story; Reproductive cycle; Seasonality

Neste estudo, nós apresentamos dados sobre tamanho da ninhada e duração do ciclo reprodutivo numa população de A. ameiva de uma área de Caatinga do nordeste do Brasil, buscando responder as seguintes perguntas: 1) Qual é o tamanho médio da ninhada nesta população? 2) O tamanho da ninhada é associado com o tamanho corporal das fêmeas? 3) A reprodução é contínua ou sazonal? O trabalho de campo para coleta dos lagartos consistiu de excursões mensais de outubro de 2008 a setembro de 2010. Adicionalmente, de junho de 2009 a maio de 2010, nós registramos a abundância de recém-nascidos e de adultos na população através da contagem de lagartos ativos em campo. Nós coletamos 15 fêmeas adultas, dez das quais estavam em condição reprodutiva. O tamanho médio da ninhada foi 5,3 ± 0,7 (range: 2–8, N = 10), e foi significativamente associado com o tamanho corporal das fêmeas. Fêmeas reprodutivas foram registradas nas estações chuvosa e seca, sugerindo um período reprodutivo prolongado ao longo do ano. Entretanto, o declínio na abundância de adultos durante o pico da estação seca e a ausência de recém-nascidos na população durante quatro meses consecutivos são indicativos de que as fêmeas não se reproduziram continuamente durante 2009-2010.Palavras-chave: Ciclo reprodutivo, História de vida, Sazonalidade, Tamanho da ninhada.Universidade Federal do AmapáSales, Raul Fernandes DantasFreire, Eliza Maria Xavier2020-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/496810.18561/2179-5746/biotaamazonia.v10n1p17-19Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 10, n. 1 (2020); 17-192179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPenghttps://periodicos.unifap.br/index.php/biota/article/view/4968/v10n1p17-19.pdfhttps://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/4968/787Caatinga; Rio Grande do Norte; Brasil; AméricasDireitos autorais 2020 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2020-05-27T00:05:55Zoai:ojs.pkp.sfu.ca:article/4968Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2020-05-27T00:05:55Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
