Brain organization in Collembola (springtails).
Arthropoda is comprised of four major taxa: Hexapoda, Crustacea, Myriapoda and Chelicerata. Although this classification is widely accepted, there is still some debate about the internal relationships of these groups. In particular, the phylogenetic position of Collembola remains enigmatic. Some molecular studies place Collembola into a close relationship to Protura and Diplura within the monop...
متن کاملA checklist of Collembola of Tehran, with some new records from Iran
در این تحقیق، فون پادمان در شهر تهران در طی سالهای 1392 تا 1393 مورد مطالعه قرار گرفت. بدین منظور، نمونه‌های پادمان از خاک و خاک‌برگ پارک‌ها، مناطق جنگلی، باغی و فضاهای سبز جمعآوری و پس از انتقال به آزمایشگاه، با استفاده از قیف برلیز استخراج شدند. از نمونه‌های موجود در الکل، اسلایدهای میکروسکوپی با استفاده از چسب هویر تهیه و در نهایت نسبت به شناسایی آنها اقدام گردید. نتایج این تحقیق در مجموع ش...
متن کاملA fossil bee from Early Cretaceous Burmese amber.
The bee fossil record is fragmentary, making it difficult to accurately estimate the antiquity of bee-mediated pollination. Here, we describe a bee fossil [Melittosphex burmensis (new species), Melittosphecidae (new family)] from Early Cretaceous Burmese amber (approximately 100 million years before the present). The fossil provides insights into the morphology of the earliest bees and provides...
متن کاملSnakefly diversity in Early Cretaceous amber from Spain (Neuropterida, Raphidioptera)
The Albian amber from Spain presently harbors the greatest number and diversity of amber adult fossil snakeflies (Raphidioptera). Within Baissopteridae, Baissoptera? cretaceoelectrasp. n., from the Peñacerrada I outcrop (Moraza, Burgos), is the first amber inclusion belonging to the family and described from western Eurasia, thus substantially expanding the paleogeographical range of the family...
متن کاملBiological identification of springtails (Hexapoda: Collembola) from the Canadian Arctic, using mitochondrial DNA barcodes
We evaluated sequence diversity in the mitochondrial cytochrome-c oxidase I (COI; EC 1.9.3.1) gene as a tool for resolving differences among species of Arctic springtails. The Collembola examined in this analysis were collected from Igloolik, Cornwallis, and Somerset islands and included representatives from all major families found in the Arctic. Members of 13 genera and 19 species were examin...
