“…At present, it is dif®cult to determine the cause of such insular variation. Ecological conditions such as island area, resource competition and limitation, immigrant selection (Heaney, 1978;, and historical geographic events (Sara, Valvo & Zanca, 1990;Motokawa et al, 1996) may play a role. Heaney (1978) concluded that variation in body size of the Asian tricoloured squirrel Callosciurus prevostii is related to island area.…”

Crocidura tadae was ®rst reported as a new species from Orchid Island by Tokuda & Kano (1936). However, both C. tadae and C. kurodai from Taiwan were considered as subspecies of C. hors®eldii by subsequent researchers. In the present study, the karyotypic and morphological differences among the potential C. tadae specimens from Taiwan main island and two offshore islands (Orchid Island and Green Island) were examined. The results revealed that there is no signi®cant difference in the karyotypes of these shrews but that their karyotype is different from that of other Crocidura species. Therefore, the Tadae's shrew C. tadae Tokuda & Kano, 1936 should be a valid species. Furthermore, morphological variation in 25 external and cranial characters of 106 specimens were analysed using univariate statistics, and eight selected characters were used for multivariate analyses. Univariate statistical comparisons of the three insular samples revealed that shrews of the Green Island population were the largest in most measurements of characters and shrews of the Orchid Island population were the smallest. Multivariate analysis differentiated the Taiwan samples from the other two insular samples. Therefore, three subspecies of C. tadae are recognized: C. t. tadae (Orchid Island); C. t. kurodai (Taiwan) and C. t. lutaoensis subsp. nov (Green Island).

“…However, Bate () originally erected the genus Nesiotites for the species from the Gymnesic Islands, Sardinia and Corsica. The identification and number of Crocidura species have also been matters of discussion (Sarà, Lo Valvo & Zanca, ; Hutterer, ; Sarà & Vitturi, ).…”

How common is gigantism in insular fossil shrews? Examining the ‘Island Rule’ in soricids (Mammalia: Soricomorpha) from Mediterranean Islands using new body mass estimation models

The evolution of organismal body size in extant and extinct ecosystems of islands (Island Rule) is receiving much attention at present. Allometric models are a reliable way to predict the weight of extinct species, but are scarce or even absent for some groups of micromammals. To fill the gap, we carried out regression models with extant species of soricids (N = 63) using measurements of teeth, cranium, and postcranial bones, and applied these to fossil insular species and their mainland ancestors. Almost all models are significant (P < 0.05), except for those based on the width of occipital condyles. The femur can be considered the most reliable body-mass predictor, producing estimations not far from those derived from teeth (excepting molar widths). Predictions of insular species (in grams) show that those belonging to the tribe Nectogalini [
