01Narrative

Der Südmarquesas-Rohrsänger (Acrocephalus mendanae) ist ein Singvogel aus der Gattung der Rohrsänger (Acrocephalus) und der Familie der Rohrsängerartigen (Acrocephalidae).Südmarquesas-Rohrsänger, in Avibase – Die Weltvogel-Datenbank. Abgerufen am . Der Vogel ist endemisch auf den südlichen Marquesas-Inseln. Das Verbreitungsgebiet betrifft Tieflandplantagen, trocken buschbestandene Hänge, Gärten, auch Dörfer bis 1070 m Höhe.A. Dyrcz und G. M. Kirwan: Southern Marquesan Reed Warbler (Acrocephalus agricola), 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. Southern Marquesan Reed Warbler Das Artepitheton bezieht sich auf Alvaro de Mendaña de Neyra, den „Entdecker“ der Marquesas-Inseln.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 Nordmarquesas-Rohrsänger (Acrocephalus percernis) angesehen und als „Marquesasrohrsänger“ (Acrocephalus mendanae) bezeichnet. Die Abgrenzung in zwei eigenständige Arten erfolgte im Jahre 2007 durch Alice Cibois.A. Cibois, J.–C. Thibault, E. Pasquet: Uniform phenotype conceals double colonization by reedwarblers of a remote Pacific archipelago. In: Journal of Biogeography. Band 34, 2007, S. 1150–1166

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.

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 solid bar is the fossil range: the span between the oldest and the youngest fossil that palaeontologists have assigned to Acrocephalus mendanae. Above itBeside it, each dot is one dated fossil find — few enough to count, so they are drawn individually rather than as a graph. 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.
