Introduced, free-ranging populations occur in S Spain, the Canary Is, USA (California, New Mexico, and Texas), and NE Mexico. Subspecies of free-ranging introduced populations are unknown because they originate from zoo animals of uncertain origin or from hybrids. Most introduced populations are probably from subspecies lervia, derived from European zoos. The Aoudad has become a widespread invasive species. in Bovidae

Phylogeny and evolution of Cupressaceae: updates on intergeneric relationships and new insights on ancient intergeneric hybridization
<p class="MsoNormal"><span>After the merger of the former Taxodiaceae and Cupressaceae <em>s.s.</em>, currently the conifer family Cupressaceae (<em>sensu lato</em>)<em> </em>comprises seven subfamilies and 32 genera, most of which are important components of temperate and mountainous forests. With the exception of a recently published genus-level phylogeny of gymnosperms inferred from sequence analysis of 790 orthologs, previous phylogenetic studies of Cupressaceae were based mainly on morphological characters or a few molecular markers, and did not completely resolve the intergeneric relationships. In this study, we reconstructed a robust and well-resolved phylogeny of Cupressaceae represented by all 32 genera, using 1944 genes (Orthogroups) generated from transcriptome sequencing. Reticulate evolution analyses detected a possible ancient hybridization that occurred between ancestors of two subclades of Cupressoideae, including <em>Microbiota-Platycladus-Tetraclinis</em> (MPT) and <em>Juniperus-Cupressus-Hesperocyparis-Callitropsis-Xanthocyparis </em>(JCHCX), although both concatenation and coalescent trees are highly supported. Moreover, divergence time estimation and ancestral area reconstruction indicate that Cupressaceae very likely originated in Asia in the Triassic, and geographic isolation caused by continental separation drove the <a name="_Hlk103290964"></a>vicariant evolution of the two subfamilies Cupressoideae and Callitroideae in the northern and southern hemispheres, respectively. Evolutionary analyses of some morphological characters suggest </span><span>that helically arranged linear-acicular leaves and imbricate bract-scale complexes represent ancestral states, and t</span><span>he shift from linear-acicular leaves to scale-like leaves was associated with the shift from helical to decussate arrangement. Our study sheds new light on phylogeny and evolutionary history of Cupressaceae, and strongly suggests that both dichotomous phylogenetic and reticulate evolution analyses be conducted in phylogenomic studies.</span></p>

FIGURE 1. Phylogenetic relationships of C. ×shangrilaense based on the combined plastid DNA. Galeandra devoniana and Eulophia graminea were used as outgroups. The three numbers near the nodes are Bayesian posterior probabilities (PP), maximum likelihood bootstrap percentages (BP ML), and maximum parsimony bootstrap percentages (BP MP), respectively. "*" indicates that the node has BP=100 or PP=1.00. "-" indicates that the node is incongruent between the topology of the Bayesian and MP/ML trees.
