Una nueva investigaci\u00f3n ha descrito c\u00f3mo funcionan las rayas de cebra para repeler a los t\u00e1banos.<\/p>\n

Los estudios realizados en los \u00faltimos a\u00f1os han demostrado que a los t\u00e1banos no les gusta posarse en las rayas, y cada vez hay m\u00e1s pruebas de que las rayas de las cebras son una adaptaci\u00f3n evolutiva para frustrarlas.<\/p>\n

Un nuevo estudio de la Universidad de Bristol se ha basado en investigaciones anteriores para analizar las razones por las que los t\u00e1banos y las moscas no quieren posarse en las rayas.<\/p>\n

Los cient\u00edficos utilizaron caballos con diferentes tipos de mantas estampadas para el estudio, que se public\u00f3 ayer (20 de febrero) en el Journal of Experimental Biology.<\/p>\n

Descubrieron que las distinciones marcadas entre blanco y negro y las peque\u00f1as manchas oscuras eran particularmente efectivas para frustrar los ataques. Su teor\u00eda es que las delgadas rayas negras minimizan las grandes manchas monocrom\u00e1ticas oscuras, que los t\u00e1banos encontrar\u00edan atractivos.<\/p>\n

\u00abSab\u00edamos que los t\u00e1banos son reacios a aterrizar en objetos rayados; varios estudios lo han demostrado ahora, pero no est\u00e1 claro qu\u00e9 aspectos de las rayas encuentran aversivos\u00bb, dijo el coautor Tim Caro.<\/p>\n

\u201c\u00bfEs la delgadez de las rayas? \u00bfEl contraste de blanco y negro? \u00bfLa se\u00f1al polarizada que pueden emitir los objetos? As\u00ed que nos dispusimos a explorar estos problemas utilizando diferentes mantas estampadas sobre los caballos y filmando a los t\u00e1banos y moscas que se acercaban\u201d.<\/p>\n

Descubrieron que los t\u00e1banos se sienten atra\u00eddos por los objetos grandes y oscuros, pero menos por los patrones oscuros y rotos. Las mantas completamente grises se asociaron con la mayor\u00eda de los descansos de las moscas, seguidas de las que ten\u00edan grandes tri\u00e1ngulos negros y luego peque\u00f1os patrones de tablero de ajedrez.<\/p>\n

\"moscas\" \"moscas\"<\/p>\n

En otro experimento, encontraron que las rayas con alto contraste atra\u00edan pocas moscas, mientras que las rayas que contrastaban menos eran m\u00e1s atractivas.<\/p>\n

\u201cEsto sugiere que cualquier caballo que represente un alto contraste contra el cielo se beneficiar\u00e1 en t\u00e9rminos de reducci\u00f3n del ataque de ectopar\u00e1sitos\u201d, agreg\u00f3 el profesor Caro.<\/p>\n

La investigaci\u00f3n fue dirigida por el profesor Caro y Martin How, de la Facultad de Ciencias Biol\u00f3gicas de la Universidad de Bristol.<\/p>","protected":false},"excerpt":{"rendered":"
