Following the invisible trail: kinematic analysis of mate-tracking in the copepod Temora longicornis.
We have analysed the fine-scale kinematics of movement of male and female copepods, Temora longicornis, to resolve how these small animals find their mates. Location of the trail initially involves rapid random turning and high rates of directional change. Males subsequently increase their rate of movement as they follow the trail, and execute a regular pattern of counter turns in both x,z and ...
متن کاملDynamics of gut pigment in the copepod Temora longicornis and the determination of in situ grazing rates
Gut fluorescence attributable to algae caten by an herbivorous zooplankter should be a function of chlorophyll consumption minus loss of pheopigments in defecation. The amount of chlorophyll ingested, as determined in a laboratory grazing experiment, minus the gut pigment content at the end in the grazers, should equal chlorophyll dcfecatcd and should also provide a calibration for the determin...
متن کاملLocating a mate in 3D: the case of Temora longicornis
Using laser optics to illuminate high-resolution video-recordings, we revealed behavioural mechanisms through which males of the calanoid copepod speciesTemora longicornis locate females. Males ofT. longicornis swam at signi¢cantly faster speeds than females along more sinuous routes, possibly re£ecting adaptations to increase encounter with females. Upon approaching within 2mm (i.e. two body l...
متن کاملromantic education:reading william wordsworths the prelude in the light of the history of ideas
عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
