Stable Isotope Dynamics in Cownose Rays (Rhinoptera bonasus) within the Northwestern Gulf of Mexico [PDF]

open access: yes, 2015
The cownose ray (Rhinoptera bonasus) is a durophagous mesopredator that exerts for top-down control on commercial shellfish stocks along the Atlantic coast. Although the trophic ecology of this elasmobranch has been the subject of extensive investigation,

An Examination of the Diet and Movement Patterns of the Atlantic Cownose Ray Rhinoptera bonasus within a Southwest Florida Estuary [PDF]

open access: yes, 2005
Cownose rays are benthic, suction feeders whose foraging activities have been implicated in severe damage to commercial shellfish industries and seagrass habitat.

Hydrodynamic effects of body-undulation kinematics on thrust production and wake-structure formation in a batoid fish (cownose ray, Rhinoptera bonasus) [PDF]

open access: yes, 2013
本文以數值方法研究牛鼻魟魚(Rhinoptera bonasus)游動之拍撲動作模式對於推進力與三維流場結構之影響。全文分為三大部分,第一部分為在週期推力方向合力為零的條件下建立完整魟魚數值模型,揭示週期定速游動之魟魚拍撲流場結構。第二部分闡述水中拍撲運動之翼尖渦流之特性與其對推力表現的影響,藉由調控順流向翼拍撲波動振幅與翼展向翼拍撲振幅,模擬不同的魟魚拍撲動作。翼尖渦流之傳遞途徑直接受到胸鰭表面波動運動軌跡的影響,在拍撲頻率與翼展向振幅不變的情況下,翼前緣的拍撲波動振幅降低 ...
