Bunun için, ekolojik niş modellemesi, moleküler filocoğrafya ile birlikte kullanılmıştır. MAXENT yazılımındaki maksimum entropi makine öğrenme algoritması kullanılarak, S. xanthoprymnus’un geçmiş [son buzullararası dönem (130 – 116 bin yıl önce) ve son buzul maksimum (21 bin yıl önce)] ve günümüz (1950 – 2000) biyoiklimsel koşulları altındaki potansiyel coğrafi dağılım alanını tahmin etmek için, bir ekolojik niş modeli geliştirilmiştir. Ayrıca, GenBank tarafından depolanan sitokrom b (cyt b) mitokondriyal (mt)DNA sekansları kullanılarak, Anadolu yer sincaplarında demografik tarih, cyt b mtDNA haplotiplerinin coğrafi dağılımı ile birlikte değerlendirilmiştir. Ekolojik niş modellemesi moleküler filocoğrafya ortak yaklaşımına göre, kendisi de ılıman kuşak (orta enlem) türü olan S. xanthoprymnus, Geç Kuvaterner buzul-buzullararası döngüleri boyunca gerçekleşen küresel iklim değişikliklerine, ılıman kuşak (orta enlem) türlerinden beklenenin aksi yönünde cevap vermiştir. Yani, Anadolu yer sincaplarının coğrafi dağılım alanı, buzul dönemlerde daralmak yerine genişlemiş, buzullararası dönemlerde ise genişlemek yerine daralmıştır. Diğer bir deyişle, S. xanthoprymnus, buzullararası dönemlerde sığınaklarda yaşamaktadır. Bu sonuçlar, ılıman kuşak türlerinin coğrafi dağılım alanının buzul dönemlerde daraldığı, buzullararası dönemlerde ise genişlediği şeklindeki klasik paradigmanın (genişleme-daralma modeli) daha önceden düşünüldüğü kadar geçerli olmadığını ileri sürmektedir.

Anahtar Kelimeler: Anadolu yer sincapları, ekolojik niş modellemesi, genişleme-daralma modeli, küresel iklim değişiklikleri, moleküler filocoğrafya, son buzul maksimum, son buzullararası dönem, Spermophilus xanthoprymnus

The major finding of bat surveys shows that montane areas have distinct chiropteran composition compared with those in lowland and logged areas. Disturbed habitats do pose a threat to the overall diversity of bats, with the generalist bats been more successful in colonising altered area than those with specialised habitat requirements. Sampling of bats targeted at different site and vegetation type from several protected areas in Sarawak have revealed the current record of bats in Sarawak and its diversity can be monitored for better management of biodiversity in this important region.

Biogeography and variation of the Malaysian fruit bat, Cynopterus brachyotis, in Sunda Shelf 2003

by M.T. Abdullah, PhD

Five more studies by BU, UKM & UNIMAS had tested and confirmed similar findings in this 2003 PhD study.

The small form is found in the closed canopy forest while the larger form utilised the open habitat. There is a new species within the C. brachyotis populations yet to be described.

Description of a new species of Aoplonema (Hemiptera: Miridae: Orthotylinae) with a biogeographic analysis and reassessment of the phylogeny of the genus.

A summary of the hypothesized phylogenetic species relationship is (A. princeps (A. lopidium (A. rubrum + A. nigrum))). A biogeographical analysis proposes that the Sierra Madre del Sur is the sister area to the rest of the areas occupied by the other species of Aoplonema.

Here we present the first evidence of giant titanosaurian sauropods from the Upper Cretaceous of North America: two enormous vertebrae and a partial femur, from the Naashoibito Member of the Ojo Alamo Formation, New Mexico, and referred to Alamosaurus sanjuanensis. One of the new vertebrae, a posterior cervical, is comparable in size to a posterior cervical described for Puertasaurus: an Argentinosaurus-sized titanosaurian from the Maastrichtian of Argentina. This makes A. sanjuanensis the largest dinosaur from North America, and among the largest in the world. These findings indicate that A. sanjuanensis is diagnosed based on immature remains, which may have implications for cladistic analyses.
