Evidence of convergent character displacement in release vocalizations of Bufo fowleri and Bufo terrestris (Anura; Bufonidae)
Anuran release vocalizations prevent prolonged amplexus of males by conspecific and heterospecific males, whereas advertisement vocalizations potentially act as a premating isolation mechanism. Selection favouring prompt release during heterospecific amplexus should result in convergent character displacement in release vocalizations. Conversely, selection should produce divergent character dis...
متن کاملزیستشناسی و الگوی غذایی گونه آسیب‌پذیر وزغ تالشی (Bufo eichwaldi) (Amphibia; Anura; Bufonidae) در ایران
چکیده دوزیستان شکارچیان فرصتطلبی هستند که از منابع غذایی با فراوانی بیشتر در محیط اطرافشان تغذیه میکنند. این گروه، به‌دلیل تغذیه از حشرات، دارای اهمیت بسزایی در تعادل و کنترل بیولوژیکی آفات کشاورزی اکوسیستمهای مختلف هستند. در این تحقیق که در سال 1395 در شمال غرب استان گیلان انجام گرفت، ضمن بررسی وضعیت زیستی گونه در معرض آسیب وزغ تالشی (Bufo eichwaldi)، محتویات معده57 نمونه، به روش شستشوی معد...
متن کاملInvestigating opposing patterns of character displacement in release and advertisement vocalizations of Bufo fowleri and Bufo americanus (Anura; Bufonidae)
Anuran release vocalizations function to prevent prolonged amplexus between males, whereas advertisement vocalizations potentially act as a premating isolation mechanism. To facilitate rapid release during heterospecific amplexus, selection should favor convergent character displacement in release vocalizations. Conversely, to promote isolation between sympatric congeners, selection should favo...
متن کاملTadpole of Bufo taitanus (Anura: Bufonidae) with Notes on Its Systematic Significance and Life History
—The tadpole of Bufo taitanus is described from material recently collected at the type locality. Tadpoles of B. taitanus possess a crownlike structure on top of the head. Observations suggest that the crown likely acts as an accessory respiratory organ. Development in B. taitanus is rapid with metamorphosis completed after just 13 days. Based on its similarity to tadpoles of Stephopaedes anoti...
متن کاملAdvertisement calls of Cuban toads of the genus Bufo (Anura, Bufonidae)
Studies conducted during the last 30 years on the vocalizations in the genus Bufo have provided relevant information about the usefulness of the acoustic signals for species identification and have been used to examine phylogenetic relationships within this genus (Brown and Littlejohn 1972, Martin 1972, Cherry and Grant 1994, Cocroft and Ryan 1995, Gergus et al. 1997, Sullivan et al. 2000, Di T...
