Sparrows and buntings : a guide to the sparrows and buntings of North America and the world by Clive Byers( Book )

3 editions published in 1995 in English and held by 255 WorldCat member libraries worldwide

Well as the buntings of Europe, Asia, and Africa, 110 species in all. The detailed, authoritative descriptions include not only the birds' identifying features but their natural history as well. The 39 color plates depict all the plumages of every species and race described. A range map is included for each species. This beautiful book will help solve the tricky identification problems posed by a delightful and diverse family of birds
Buntings and sparrows : a guide to the buntings and North American sparrows by Clive Byers( Book )

19 editions published between 1995 and 2013 in English and held by 102 WorldCat member libraries worldwide

Über die Inaktivierung der Amylase by Urban Olsson( )

7 editions published in 1925 in German and held by 20 WorldCat member libraries worldwide

Buntings and sparrows by Clive Byers( )

3 editions published between 1995 and 2010 in English and held by 15 WorldCat member libraries worldwide

Covers all the buntings (Palearctic) and sparrows (Nearctic) - 108 species - of the Holarctic region. These birds are members of the sub-family emberizinae, and are represented in nearly every habitat in the region. They also present considerable identification problems

Linneaus's Legacy Systematic Challenges, Past and Present by Urban Olsson( )

1 edition published in 2007 in Undetermined and held by 1 WorldCat member library worldwide

Tulisan ini menyampaikan perkembangan ilmu sistimatik. Pandangan Linnaeus menyerupai pandangan Aristotle dalam hal mengelompokkan organisme mengikuti Scala Naturae yaitu berdasarkan kemiripan. Namun pendekatannya berbeda, Aristotle lebih menekankan bahwa karakter yang berkaitan dengan gaya hidup organisme seperti bentuk tubuh sangat penting untuk klasifikasi.Sedangkan menurut Linnaeus justru karakter yang tidak terlihat, tetapi sangat penting dalam mempertahankan hidup sehari-hari justru jauh lebih penting. Saat ini kita menyusun organisme berdasarkan pohon filogenetik dengan cara mengelompokkannya kedalam kelompok monofiletik atau disebut juga kelompok alami yaitu dimasukkan kedalam suku (famili), ordo dan filum.Jenis-jenis yang termasuk kelompok tersebut harus berasal dari nenek moyang yang sama.Perbedaan yang terjadi pada bentuk tubuh atau fungsi bagian tubuh dipaparkan dengan ,cladistic'.Perkembangan pesat di bidang biologi molekuler termasuk tehnik-tehnik DNA dalam beberapa dasawarsa terakhir ini sangat membantu mengurai persoalan rumit yang dijumpai dalam melakukan klasifikasi
Explosive radiation and spatial expansion across the cold environments of the Old World in an avian family by Baoyan Liu( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Our objective was to elucidate the biogeography and speciation patterns in an entire avian family, which shows a complex pattern of overlapping and nonoverlapping geographical distributions, and much variation in plumage, but less in size and structure. We estimated the phylogeny and divergence times for all of the world's species of Prunella based on multiple genetic loci, and analyzed morphometric divergence and biogeographical history. The common ancestor of Prunella was present in the Sino-Himalayan Mountains or these mountains and Central Asia-Mongolia more than 9 million years ago (mya), but a burst of speciations took place during the mid-Pliocene to early Pleistocene. The relationships among the six primary lineages resulting from that differentiation are unresolved, probably because of the rapid radiation. A general increase in sympatry with increasing time since divergence is evident. With one exception, species in clades younger than c. 3.7 my are allopatric. Species that are widely sympatric, including the most recently diverged (2.4 mya) sympatric sisters, are generally more divergent in size/structure than allo-/parapatric close relatives. The distributional pattern and inferred ages suggest divergence in allopatry and substantial waiting time until secondary contact, likely due to competitive exclusion. All sympatrically breeding species are ecologically segregated, as suggested by differences in size/structure and habitat. Colonizations of new areas were facilitated during glacialperiods, followed by fragmentation during interglacials-contrary to the usual view that glacial periods resulted mainly in fragmentations
