Comparative analysis of long-range calls in equid stallions (Equidae): are acoustic parameters related to social organization?
Item type: Journal Article • Journal: African Zoology • Authors: Richard Policht --- Institute of Tropics and Subtropics, Czech University of Life Sciences Prague, Czech Republic Alexis Karadžos --- Department of Zoology, Faculty of Science, Czech Republic Daniel Frynta --- Department of Zoology, Faculty of Science, Czech RepublicEvolution of long-distance communication in equids may correspond with species-specific types of social organization. To compare harem-forming species (type I) with those that do not establish permanent social units (type II), we conducted a comparative analysis of stallion long-range calls... -
Characteristics of the alarm calls of buff-streaked chat groups and African stonechat pairs in response to increased distances from surrogate raptors and snakes
Item type: Journal Article • Journal: African Zoology • Authors: N. Seoraj-Pillai --- Department of Nature Conservation, South Africa G. Malan --- Department of Nature Conservation, South AfricaMany animals emit alarm calls in response to a potential predator. These calls may transmit information about predator type and response urgency. This study compared the alarm calls of the social buff-streaked chat, Oenanthe bifasciata, to the asocial African stonechat,... -
