摘要

动物行为可能是个体饮食专业化的一种机制。为了探索这种可能性，我们评估了蓝山雀(Cyanistes caeruleus)种群的探索行为和觅食数据。研究结果表明:1)觅食方式存在性别差异;2)雌虫选择的猎物类型取决于其配偶的供给率，并且这种猎物选择的调整在不同的EB表型之间存在差异;3)雄虫的觅食行为与其EB表型呈连锁关系，探索速度快的雄虫获得的幼虫略大，但觅食频率低于探索速度慢的雄虫。最后，环境变量对后代的饮食构成有很大影响。因此，我们不能认为EB占主导地位，但它可能有助于我们研究人群的饮食专业化过程。

Exploration behaviour and foraging strategies in Mediterranean blue tits

Animal behaviour is potentially a mechanism of individual diet specialization. To explore this possibility we assessed exploratory behaviour (EB) and foraging data for a population of blue tits Cyanistes caeruleus. Our results suggest that: 1) foraging differs between sexes; 2) the prey type selected by females depends on the provisioning rates of their mate, and adjustment of this prey-choice differs between EB phenotypes; and 3) foraging behaviour in males shows a trend towards linkage to their EB phenotype, with faster-exploring males obtaining marginally larger caterpillars but provisioning less frequently than slower-exploring males. Lastly, environmental variables contributed substantially to the diet composition of offspring. For this reason, we cannot suggest that EB dominates, but it may contribute to a diet specialization process in our study population.

期刊介绍： Animal Biodiversity and Conservation (antes Miscel·lània Zoològica) es una revista interdisciplinar, publicada desde 1958 por el Museu de Ciències Naturals de Barcelona. Incluye artículos de investigación empírica y teórica en todas las áreas de la zoología (sistemática, taxonomía, morfología, biogeografía, ecología, etología, fisiología y genética) procedentes de todas las regiones del mundo. La revista presta especial interés a los estudios que planteen un problema nuevo o introduzcan un tema nuevo, con hipòtesis y prediccions claras, y a los trabajos que de una manera u otra tengan relevancia en la biología de la conservación. No se publicaran artículos puramente descriptivos, o artículos faunísticos o corológicos en los que se describa la distribución en el espacio o en el tiempo de los organismes zoológicos.
