Habitat use and population genetics of golden jackals in Iran: Insights from a generalist species in a highly heterogeneous landscape
Generalist species are often characterized by low habitat specialization and reduced genetic structure in their populations. Here, we tested this common assumption on golden jackals in Iran, a wide country with a highly heterogeneous landscape where this carnivore is assumed to be widespread, although little is known about the ecology and population genetics of this species. We investigate distribution patterns, habitat requirements, and niche breadth of golden jackals by using GIS techniques and ecological modeling over a total of 452 presence records. We then assessed genetic diversity and population structure by analyzing 24 samples for 43 microsatellites. The observed distribution patterns show an extensive range across a wide climatic, ecological and altitudinal gradient, covering eight climate regions and 16 terrestrial ecoregions. Ecological modeling confirms high habitat plasticity of the golden jackal, with selection of mountainous areas with high slopes, moderate temperatures, and areas with low human population and activity while avoiding hyper-arid regions. Estimated values of niche breadth were high, indicating that is a generalist species in the study area. The observed genetic diversity was high, representing the highest value reported so far in this species. We found no signature of population structure, suggesting a single genetic cluster, as well as no evidence of hybridization with domestic dogs. Our results provide valuable ecological and genetic information on a widespread but poorly known carnivore, often disregarded in conservation strategies but under pressure from anthropogenic threats.
期刊介绍:
The Journal of Zoological Systematics and Evolutionary Research (JZSER)is a peer-reviewed, international forum for publication of high-quality research on systematic zoology and evolutionary biology. The aim of the journal is to provoke a synthesis of results from morphology, physiology, animal geography, ecology, ethology, evolutionary genetics, population genetics, developmental biology and molecular biology. Besides empirical papers, theoretical contributions and review articles are welcome. Integrative and interdisciplinary contributions are particularly preferred. Purely taxonomic and predominantly cytogenetic manuscripts will not be accepted except in rare cases, and then only at the Editor-in-Chief''s discretion. The same is true for phylogenetic studies based solely on mitochondrial marker sequences without any additional methodological approach. To encourage scientific exchange and discussions, authors are invited to send critical comments on previously published articles. Only papers in English language are accepted.
