Comparison of the ectosymbionts and parasites of an introduced crab, Charybdis japonica, with sympatric and allopatric populations of a native New Zealand crab, Ovalipes catharus (Brachyura: Portunidae)
the success of biological invaders is often attributed to escape from specialist enemies in their natural range, such as predators and parasites. For enemy escape to have direct consequences in competitive interactions, invaders need to be less vulnerable to enemies than native competitors in the region they invade, but first the presence of these enemies must be established. We investigated th...
متن کاملA unique form of light re ̄ector and the evolution of signalling in Ovalipes (Crustacea: Decapoda: Portunidae)
The ¢rst demonstration, to our knowledge, of an evolutionary shift in communication mode in animals is presented. Some species of Ovalipes display spectacular iridescence resulting from multilayer re£ectors in the cuticle. This re£ector is unique in animals because each layer is corrugated and slightly out of phase with adjacent layers. Solid layers are separated from £uid layers in the re£ecto...
متن کاملPopulation ecology of the blue crab Callinectes danae (Crustacea: Portunidae) in a Brazilian tropical estuary.

متن کاملNew Zealand Bodotriidae (Crustacea: Cumacea).
The cumacean fauna of New Zealand has been little studied, and recent collections on the Chatham Rise and Challenger Plateau have yielded many new species and new genera of Cumacea. A recent manuscript on the New Zealand Nannastacidae (Gerken 2012) increased the described New Zealand fauna by 66%. Within the Bodotriidae, 6 new species were discovered. The new species Apocuma chathamensis n. sp....

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
