Abstract

In this paper, we report the unusual presence of extant termite nests in frontal beach eolian sandy substrates in the Rio Grande do Sul Coastal Plain (southernmost Brazil) and describe the nest architectures, aiming to compare them with termite fossil nests preserved in Pleistocene backshore deposits of this same coastal plain. Four sites were analyzed along the modern beach, and the architecture of the termite nests was described. The nests are composed of a rounded convex epigeal portion and a hypogeal portion with variable dimensions formed by interconnecting spherical to semispherical chambers. Considering that termites are assumed to colonize more mature, vegetated soils due to the need for abundant cellulosic material, the occurrence of termite nests in backshore dunes close to the shoreline opens a discussion about the distribution and habit of termites and the applicability of their trace fossils for paleoenvironmental reconstitutions.

风成后海岸环境中的白蚁巢:整个第四纪在新热带地区的不寻常记录

在这篇论文中，我们报道了在里约热内卢Grande do Sul海岸平原(巴西最南端)的前缘海滩风成沙基质中现存白蚁巢穴的不寻常存在，并描述了巢穴的结构，旨在将它们与保存在同一海岸平原更新世后海岸沉积物中的白蚁化石巢穴进行比较。分析了现代海滩沿线的四个地点，并描述了白蚁巢的结构。巢由圆形凸的上表皮部分和具有可变尺寸的下表皮部分组成，该下表皮部分通过连接球形至半球形腔室形成。考虑到白蚁因需要丰富的纤维素物质而被认为在更成熟的植被土壤中定居，白蚁巢在靠近海岸线的后海岸沙丘中的出现，开启了关于白蚁分布和习性及其痕迹化石在古环境重建中的适用性的讨论。金伯利·席尔瓦·拉莫斯。Unisinos大学地质研究生项目研究小组，Unisinos, 950,93022000，巴西RS o Leopoldo。kimberlyr@edu.unisinos.br Renata guimar es Netto。Unisinos大学地质研究生项目研究小组，Unisinos, 950,93022000，巴西RS o Leopoldo。nettorg@unisinos.br丹尼尔·塞多科。Unisinos大学地质研究生项目研究小组，Unisinos, 950, 9302.2 000，巴西，RS， o Leopoldo和印度联邦大学，Laboratório de古生物学应用，Monte Carmelo校区。11月15日，501，博阿维斯塔，蒙特卡梅罗- MG。38500 - 000年,巴西。sedorko@ufu.br
