Padrões de assimetria associados à ecologia de cinco espécies de lagartos tropicais Cnemidophorus (Squamata, Teiidae) em áreas de restinga ao longo da costa leste brasileira

O estudo da instabilidade do desenvolvimento (ID) em organismos pode ser útil para identificar os primeiros sinais de estresse ambiental. Alterações na ID também influenciam a aptidão dos organismos. A variação entre a simetria dos lados esquerdo e direito, manifestada como assimetria flutuante (AF), é um indicador da ID. Ao quantificarmos a literatura científica referente aos estudos de assimetria em répteis identificamos as seguintes tendências: perturbações ambientais aumentam a AF nas populações, fêmeas tendem a escolher machos com características sexuais simétricas, a instabilidade térmica durante o desenvolvimento do ovo pode produzir indivíduos com maior assimetria, a ocorrência de lesões é mais frequente em indivíduos assimétricos para um determinado lado e há uma correlação negativa entre a assimetria e o desempenho locomotor. Considerando os nossos critério de busca, não encontramos estudos sobre assimetria em répteis na América do Sul. Neste estudo, utilizamos diferentes caracteres merísticos e métricos bilaterais para identificar a AF em diferentes populações de cinco espécies de lagartos do gênero Cnemidophorus (C. abaetensis, C. lacertoides, C. littoralis, C. nativo, C. ocellifer) em 15 áreas de restinga ao longo da costa leste do Brasil. A AF foi maior em populações de Cnemidophorus com maior densidade, menor em populações de restingas com maior degradação ambiental e a sua relação com a concentração de mercúrio variou dependendo da espécie. Provavelmente os agentes estressores ambientais avaliados atuam com intensidades diferentes. O nível de degradação ambiental e a concentração de mercúrio causariam a deterioração precoce dos indivíduos com maiores valores de AF. Isso resulta em uma relação inversa entre esses estresses e a AF das populações. Indivíduos com vestígios de autotomia caudal tiveram maiores valores de AF, o que pode ser um indicativo de que indivíduos com menor aptidão efetuam mais autotomia caudal do que aqueles com maior aptidão. Lagartos com evidências de autotomia também tiveram maior tamanho corpóreo, provavelmente devido a estes estarem expostos a mais tempo aos riscos de predação. Não encontramos diferenciação entre as espécies na frequência de autotomia caudal sendo esta talvez melhor explicada por fatores ambientais como a intensidade de predação. Os índices de AF para caracteres múltiplos se mostraram mais eficientes do que a AF de caracteres individuais nas comparações entre indivíduos vivendo em populações com diferentes níveis de estresse e entre indivíduos com e sem autotomia caudal
