Amphibians of Australia are limited to members of the order Anura , commonly known as frogs. All Australian frogs are in the suborder Neobatrachia , also known as the modern frogs, which make up the largest proportion of extant frog species. The Australian continent once formed part of the supercontinent Pangaea , which split into Gondwana and Laurasia approximately million years ago.

Processing, editing, and typesetting of manuscripts is carried out by an international team of editors.

Fauna of Australia

Dissection of 1, specimens provided data on reproductive cycles in six genera of skinks and three genera of agamids from the Alligator Rivers Region of Australia's Northern Territory. Comparative data on lizards from the temperate zone were gathered by dissecting specimens of three genera, and by reviewing published studies. The Alligator Rivers Region climate exhibits uniformly high temperatures but extremely seasonal rainfall.

By analogy with studies on tropical herpetofaunas in other parts of the world, we hypothesised that most species would breed during the wet-season. Instead, a great diversity in the seasonal timing of reproduction in tropical lizards was observed. For example, among the skinks, Cryptoblepharus breeds year-round, Carlia and Sphenomorphus breed in the wet-season, whereas Lerista, Morethia and most but not all Ctenotus breed during the dry-season.

Among the agamids, Diporiphora and Gemmatophora breed in the wet-season, and Chelosania in the dry-season. Temperate-zone lizards in Australia show less interspecific variation: all species breed in late spring and summer. Hypotheses concerning the evolutionary determinants of reproductive seasonality are reviewed in the light of these data. Thermal tolerances of developing embryos are unlikely to be important in determining breeding seasons of the Alligator Rivers Region herpetofauna, as there is little seasonal variation in temperature.

Differences in reproductive timing between microsympatric species are inconsistent with hypotheses giving a major role to the seasonality of fire, flooding or intensity of predation. There is no clear association between food habits and reproductive timing. The best predictor of breeding seasonality seems to be the biogeographic history of the taxon.

Alligator Rivers Region representatives of arid-zone taxa tend to breed in the dryseason, whereas representatives of mesic-adapted lineages tend to be wet-season breeders. A species from one cosmopolitan genus breeds year-round. We hypothesize that embryonic moisture tolerances may be an important determinant of breeding seasonality in this region, although some cases do not support this conclusion.

Location biases in ecological research on Australian terrestrial reptiles

Australian Reptiles and Frogs The definitive book. This definitive book by the Snakeman Raymond Hoser was highly sought after when it came out in and the 7, copies printed sold out by the mid 's. This exceptionally high quality CD-Rom also contains a vast number of other definitive and otherwise hard to get Australian wildlife publications including the book, Endangered Animals of Australia , also by Raymond Hoser, over major wildlife papers and articles by a number of authors and more. To find out more about this amazing CD-rom:. School teachers and others can now obtain for free for private use, full pdf page proofs mb each file of two definitive Australian wildlife texts by clicking the relevant text below.

Michael J. Australian Zoologist 1 December ; 38 2 : — The total identified herpetofauna community comprised 11 frog species three families and 35 reptiles 10 families and includes a mix of eastern Bassian , western Eyrean and northern Torresian species. This study demonstrates the significant species diversity, biogeographical interest and conservation value of the Pilliga forest's herpetofauna. Noteworthy findings from this study included a number of declining woodland reptile species Nobbi Diporiphora nobbi , Australian Coral Snake Brachyurophis australis and Inland Carpet Python Morelia spilota metcalfei , locally rare species Excitable Delma Delma tincta and Southern Rainbow Skink Carlia tetradactyla and edge of range species Litter Skink Lygisaurus foliorum. The study provides a useful benchmark of the composition and status of the herpetofauna community of Yarrigan NP in the first decade following a land management shift from timber production to conservation.

For each of the species there is a description of its appearance, distribution and habits. These descriptions are also accompanied by distribution maps and, in many cases, one of the book's more than colour photographs of living animals. In addition, it has a comprehensive list of scientific references for those wishing to conduct more in-depth research, an extensive glossary, and basic guides to the collection, preservation and captive care of specimens. This classic work was originally published in

Попав по назначению, программа фиксировала свое местонахождение в Интернете и передавала его в АНБ, после чего бесследно уничтожала маяк. Начиная с того дня, анонимные переадресующие компании перестали быть для АНБ источником серьезных неприятностей. - Вы сможете его найти? - спросил Стратмор. - Конечно. Почему вы не позвонили мне раньше. - Честно говоря, - нахмурился Стратмор, - я вообще не собирался этого делать.

 Мне кажется, коммандер приказал вам уйти. - Но монитор. Она показывает восемнадцать… - Коммандер Стратмор велел вам уйти. - Плевал я на Стратмора! - закричал Чатрукьян, и его слова громким эхом разнеслись по шифровалке. - Мистер Чатрукьян? - послышался сверху звучный возглас.

 Да поможет нам Бог, - прошептала.  - Мы можем принять участие в аукционе. Стратмор покачал головой: - Танкадо дал нам шанс. Это совершенно ясно. Тем не менее риск велик: если нас обнаружат, это, в сущности, будет означать, что он своим алгоритмом нас напугал.

Экран погас.

 Выключите ТРАНСТЕКСТ! - потребовала. Остановка поисков ключа Цифровой крепости высвободила бы достаточно энергии для срабатывания дверных замков. - Успокойся, Сьюзан, - сказал Стратмор, положив руку ей на плечо. Это умиротворяющее прикосновение вывело Сьюзан из оцепенения.

ГЛАВА 22 Дэвид Беккер быстро подошел к койке и посмотрел на спящего старика. Правое запястье в гипсе. На вид за шестьдесят, может быть, около семидесяти. Белоснежные волосы аккуратно зачесаны набок, в центре лба темно-красный рубец, тянущийся к правому глазу.

Я умер. Но я слышу какие-то звуки. Далекий голос… - Дэвид. Он почувствовал болезненное жжение в боку.

Ей в голову пришла и другая мысль - известно ли Хейлу, что Танкадо уже нет в живых.

    Species producing more than one clutch per year are larger than single-clutched ones.

    A unique feature of Australia's fauna is the relative scarcity of native placental mammals.
