Tropical niche conservatism explains the Eocene migration from India to Southeast Asia in Ochyroceratid spiders
<p><span>Biological migrations between India and Southeast (SE) Asia provide an ideal system for exploring the effects of geology and climate on species ranges. Geologists have confirmed that the direct collision between India and Eurasia occurred in the Early Eocene, but most migrations occurred between the Indian subcontinent and SE Asia rather than the former and the southern margin of Eurasia. To explain this seemingly paradoxical disconnect between the routes of plate movement and biological migration, we studied the evolutionary history of the tropical spider family Ochyroceratidae based on 101 globally distributed species. We infer a robust dated phylogeny using both transcriptomic data and a dataset of classical markers and relate these to biogeographic and climatic analyses. Our results indicate that the monophyly of Ochyroceratidae is strongly supported, and the divergence times suggest a Cretaceous Gondwanan origin of the family. Reconstructed biogeographic histories support a dispersal event from the Indian subcontinent to islands of SE Asia 55–38 million years ago. Climatic analyses and the fossil record reveal that ochyroceratids are characterized by a high degree of tropical niche conservatism, and that the ancestor of the Indian and SE Asian clades originated in very warm, wet environments. Early Eocene tropical, perhumid climates in India and SE Asia may have facilitated ochyroceratid migration, whereas the dry or seasonal climate extending from the eastern coast of China to Central Asia may have acted as a barrier, preventing dispersal. Our analyses suggest that climate plays a more important role than geology in biological migration from the Indian subcontinent to SE Asia, providing new insights into the Indian–Asian biogeographic link.</span></p>

Fig. 2. Bayesian tree obtained from the analyses of COI and Cytb genes. The values on the nodes indicate posterior probabilities (PP). In the COI tree, PPs were calculated from two DNA alignments of CO1 sequences (728 nt or 291 nt; see text for details). The sequence HM914921 was obtained from a specimen originally identified as T. robustula. In the Cytb tree, the sequence EU521635 was obtained from a specimen originally identified as T. robustula.

Phenotypic plasticity determines differences between the skulls of tigers from mainland Asia
<p>Tiger subspecific taxonomy is controversial because of morphological and genetic variation found between now fragmented populations, yet the extent to which phenotypic plasticity or genetic variation affects phenotypes of putative tiger subspecies has not been explicitly addressed. In order to assess the role of phenotypic plasticity in determining skull variation, we compared skull morphology amongst continental tigers from zoos and the wild. In turn, we examine continental tiger skulls from across their wild range, to evaluate how the different environmental conditions experienced by individuals in the wild can influence morphological variation. Fifty-seven measurements from 172 specimens were used to analyse size and shape differences amongst wild and captive continental tiger skulls. Captive specimens have broader skulls, and shorter rostral depths and mandible heights than wild specimens. In addition, sagittal crest size is larger in wild Amur tigers compared with those from captivity, and it is larger in wild Amur tigers compared to other wild continental tigers. The degree of phenotypic plasticity shown by the sagittal crest, skull width, and rostral height suggests that the distinctive shape of Amur tiger skulls compared with that of other continental tigers is mostly a phenotypically plastic response to differences in their environments. </p>

Genetic diversity, genetic differentiation and demographic history of Cryptomeria (Cupressaceae), a Tertiary relict plant in East Asia based on RAD sequencing
<p>Genetic structure and distribution patterns of modern floras are strongly affected by climatic change and geographical isolation. In the present study, we applied restriction-site-associated DNA sequencing (RAD-seq) to analyze the genetic structure and to simulate the demographic history of two extant <em>Cryptomeria</em> species in Japan (<em>C. japonica</em>) and Southeastern China (<em>C</em>. <em>japonica</em> var. <em>sinensis</em>). Thirteen natural populations representing the entire species distributed in East Asia were collected from Japan and China. At the species level, the genetic diversity of <em>Cryptomeria</em> was moderate (<em>H<sub>o</sub></em> = 0.217, <em>H<sub>e</sub></em> = 0.203) with a significant genetic differentiation among populations (85.30%, P < 0.001), especially between Japan and China lineages (<em>F</em><sub>ST</sub> = 0.147). Except for the Lushan (LS) population in China, all populations were clustered into two lineages (Japanese and Chinese), which was consistent with their geographical distribution. Approximate Bayesian computations (ABC) model indicated that the current two geographical lineages diverged from a common ancestral lineage and that their divergence time was about 0.417 ~ 0.139 million years ago (Mya). Geographical isolation, climate change in the Quaternary, and human disturbance played important roles in genetic variation and distribution patterns of <em>Cryptomeria</em> in East Asia. Our results shed light on the speciation processes of <em>Cryptomeria</em> and provide a reference for the conservation of this species.</p>
