01Narrative

Der Basrarohrsänger (Acrocephalus griseldis) ist ein Singvogel aus der Gattung der Rohrsänger (Acrocephalus) und der Familie der Rohrsängerartigen (Acrocephalidae).Basrarohrsänger, in Avibase – Die Weltvogel-Datenbank. Abgerufen am . Die Art kommt als Brutvogel und Sommervogel im Irak im Osten am Euphrat und Tigris und im Südwesten des Irans vor. Sie überwintert in Ostafrika von Somalia bis Mosambik und Malawi. Kürzlich nachgewiesen wurden Bruten in Kuwait und Israel. Das Verbreitungsgebiet umfasst Schilf, Rohrkolben und ähnliche dichte Wasserpflanzen. Auch im Winterquartier werden dichtes Dickicht in Wassernähe mit feuchtem Untergrund und saisonal überflutete Lebensräume bevorzugt.A. Dyrcz: Basra Reed Warbler (Acrocephalus griseldis), version 1.0. In: J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie und E. de Juana (Herausgeber): Birds of the World. 2020, Cornell Lab of Ornithology, Ithaca, NY, USA. Basra Reed Warbler Das Artepitheton könnte von kommen, die Ableitung ist jedoch ungewiss.J. A. Jobling: A Dictionary of Scientific Bird Names. Oxford University Press. 1991. ISBN 0-19-854634-3. Früher wurde die Art als konspezifisch mit dem Drosselrohrsänger (Acrocephalus arundinaceus) angesehen.

05DNA & barcoding2 specimens

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Acrocephalus griseldis has left across the world's sequence archives.

07Deep time~6.06 Ma lineage

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin6.06 Ma TimeTree

When this lineage existed

How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

09Environmental DNA2 detections

Where the DNA of Acrocephalus griseldis was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
