摘要

在此之前，人们对古北大陆西部阳光充足的少营养草原和石南荒原上常见的单爪蟋蟀Gryllus campestris Linnaeus进行了大量的研究，但没有一项研究显示其洞穴的特征。本文介绍了一项基于一组生活在阿尔巴尼亚地拉那地区东部Dajti山牧场及其周围的G. campestris的新技术研究。它包括对野外洞穴的直接观察，以及用白色波特兰水泥制作的洞穴模型。雌雄同体的洞穴呈管状，面朝太阳，只有一个漏斗状入口，末端简单，无分枝。本研究首次揭示了蟋蟀穴居的形态特征和穴居活动，是对土壤技术的贡献。洞穴可以通过填充来保存，例如在洪水期间用沙子填充。这些洞穴不适合任何现存的鱼类群。

Burrows of the common field-cricket Gryllus campestris Linnaeus, 1758 (Orthoptera: Gryllidae) from Dajti Mountain, Albania

Abstract Considerable studies of the univoltine, common field-cricket Gryllus campestris Linnaeus, 1758, known from sunny oligotrophic grasslands and heathlands of the western Palaearctic, were previously made, but none of them has shown the characteristics of its burrows. This paper presents a neoichnological study based on a group of G. campestris that lives in and around a pasture glade in Dajti Mountain, east of the Tirana District in Albania. It includes direct observations of the burrows in the field and their casts made by means of white Portland cement. Burrows of nymphs of G. campestris were observed to be tubular, sun-facing and have only one, funnel-like entrance, simple termination and no branches. This study is the first one showing morphological features of the burrows and the burrowing activity of the common field-cricket, being a contribution to ichnology of soils. Preservation of the burrows is possible by their filling, for instance by sand during flooding. The burrows do not fit to any existing ichnotaxa.

期刊介绍： The foremost aim of Ichnos is to promote excellence in ichnologic research. Primary emphases center upon the ethologic and ecologic significance of tracemaking organisms; organism-substrate interrelationships; and the role of biogenic processes in environmental reconstruction, sediment dynamics, sequence or event stratigraphy, biogeochemistry, and sedimentary diagenesis. Each contribution rests upon a firm taxonomic foundation, although papers dealing solely with systematics and nomenclature may have less priority than those dealing with conceptual and interpretive aspects of ichnology. Contributions from biologists and geologists are equally welcome. The format for Ichnos is designed to accommodate several types of manuscripts, including Research Articles (comprehensive articles dealing with original, fundamental research in ichnology), and Short Communications (short, succinct papers treating certain aspects of the history of ichnology, book reviews, news and notes, or invited comments dealing with current or contentious issues). The large page size and two-column format lend flexibility to the design of tables and illustrations. Thorough but timely reviews and rapid publication of manuscripts are integral parts of the process.
