Seismic detection and communication in amphibians
To date, seismic communication has been demonstrated in a single amphibian, the frog Leptodactylus albilabris. Calling males produce both acoustic and seismic signals simultaneously. The inflating vocal sac not only aids in radiating the call into the air, but also strikes the wet substrate generating vertically polarized Rayleigh waves. These animals are highly sensitive to seismic signals (-1...
متن کاملPheromone communication in amphibians and reptiles.
This selective review considers herpetological papers that feature the use of chemical cues, particularly pheromones involved in reproductive interactions between potential mates. Primary examples include garter snake females that attract males, lacertid lizards and the effects of their femoral gland secretions, aquatic male newts that chemically attract females, and terrestrial salamander male...
متن کاملHormones and acoustic communication in anuran amphibians.
Circulating hormone levels can mediate changes in the quality of courtship signals by males and/or mate choice by females and may thus play an important role in the evolution of courtship signals. Costs associated with shifts in hormone levels of males, for example, could effectively stabilize directional selection by females on male signals. Alternatively, if hormone levels affect the selectio...
متن کاملSeismic sensitivity and communication in subterranean mammals
Many subterranean mammals are reported to generate or respond to seismic vibrations. Potential uses of seismic sensitivity in these animals include intraspecific communication between burrow systems, location of prey, detection of predators and even “seismic echolocation” of distant obstacles. Although the auditory and/or somatosensory systems have been variously implicated, the mechanisms used...

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
