Annually emerging cicadas are a numerically and ecologically dominant species in Southwestern riparian forests. Humans have altered disturbance regimes that structure these forests such that floods are less common and wildfires occur more frequently than was historically the case. Impacts of these changes on primary consumers such as riparian cicadas are unknown. Because cicadas are consumed by...

We investigated signalling behavior in relation to social context in the cicada Fidicina mannifera. Four types of acoustic signals were recorded from males: songs, calls, low-amplitude songs, and disturbance sounds. Signal types were similar in frequency and fine temporal structure, but differed markedly in gross temporal structure. Songs and calls were the most frequently observed signals, and...

In the gorge of Ročica creek in southwestern Julian Alps we documented (with phytosociological relevés and tables) six plant communities moist rock crevices nine forest shrub that belong four Natura 2000 habitat types. The studied is unique for stands syntaxa Astrantio carniolicae-Pinguiculetum alpinae var. Valeriana saxatilis, Palustriello commutati-Veronicetum urticifolia, Veronico urticifoli...

Ilustrasi bergambar merupakan salah satu media komunikasi visual yang memiliki kemampuan untuk menjelaskan lebih jauh dibanding dengan foto menggunakan detail elemen visual. Oleh karena itu, bergantung pada semiotika menafsirkan tanda dan simbol. Salah contoh karyanya adalah buku ilustrasi “Cicada” karya Shaun Tan menyampaikan kondisi dunia kerja kedalamnya. Selain itu adanya fenomena semakin s...

In many insects the first abdominal segment possesses embryonic appendages called pleuropodia. Here we show the embryogenesis of pleuropodial cells of the periodical cicada, Magicicada cassini (Fisher 1851) (Insecta, Homoptera, Cicadidae). An antibody, anti-horseradish perioxidase (HRP), that is usually neuron-specific strongly marked the pleuropodial anlagen and revealed their ectodermal origi...

The tymbal muscle fiber in the cicada closely resembles the indirect flight muscle fiber in its structural detail. We agree with other authors that the tymbal muscle is a modified indirect flight muscle. The peripheral nerve branches to the tymbal and flight muscle fibers are similar to those in the wasp leg. The axon is loosely mantled by irregular turns of the mesaxon, enclosing cytoplasm. Th...
