RMRS-RN-11WWW: Hosts and Geographic Distribution of Arceuthobium oxycedr


Methods

We obtained and reviewed host reports and distribution information for Arceuthobium oxycedri using the Mistletoe Literature Database (online), original publications, and collections from several herbaria:

In addition, the records of a small herbarium maintained by the Forest Department, Turkish Cyprus at the Alevkaya Forest Station were examined.

We adapted a species definition for Juniperus based on published taxonomy (Rushforth 1987; Welch and Haddow 1993; Farjon 1998) and the present work of one of us (Adams) using leaf essential oils and RAPDs (Adams 1999, 2000; Adams and Demeke 1993; Adams and Turuspeckov 1998). We attempted to identify each distribution report or collection record on current or historical maps (e.g., Guldescu 1970) to establish precise geographic location, modern spelling, and type (i.e., political unit, human settlement, or physiographic feature). Identified locations are presented in tables and maps; dubious reports and unidentified locations (in italics) are presented in the text.

Many references (e.g., Turrill 1920) review or repeat information from other references, collections or original reports. Although we examined as many references as we could obtain, we did not intend to generate an all-inclusive list of citations or collections. Rather, we strived to construct a comprehensive distribution-one in which all countries and regions where juniper dwarf mistletoe could be found are represented and significant populations are mapped. We present the numerous, unidentified sites we report as a challenge for others to locate. The extensive and discontinuous juniper forest from Morocco to China is a vast region where others might discover additional populations of this parasite.
