The Pacific tarpon Megalops cyprinoides is a euryhaline fish that is widely distributed in offshore waters of the tropical and subtropical Indo-Pacific Ocean. It spawns in offshore waters and the larvae drift with tidal currents before recruiting to estuarine nursery areas at ~25 to 30 d posthatching. Young Pacific tarpon are found in coastal waters, rivers, estuaries, inner bays, and mangrove ...

The vestibulo-ocular reflex (VOR) generates compensatory eye movements in response to angular and linear acceleration sensed by semicircular canals and otoliths respectively. Gaze stabilization demands that responses to linear acceleration be adjusted for viewing distance. This study in humans determined the transient dynamics of VOR initiation during angular and linear acceleration, modificati...

Engagement of the otolith organs elicits differential activation of sympathetic nerve activity and vascular responses to muscle and skin in humans. Additionally, aging attenuates the otolith organ-mediated increases in muscle sympathetic nerve activity in older adults. In this study, we hypothesized that 1) the vestibulosympathetic reflex (VSR) would elicit visceral vascular vasoconstriction an...

We examined growth of recently settled juvenile red drum in salt marsh, seagrass, oyster reef, and on nonvegetated bottom areas in the Galveston Bay system of Texas (USA). We estimated growth using otolith microstructure from free-ranging fish collected in different habitat types and also measured growth of red drum in experimental enclosures where fish movement was restricted. Otolith growth w...

Ocean acidification affects a wide diversity of marine organisms and is of particular concern for vulnerable larval stages critical to population replenishment and connectivity. Whereas it is well known that ocean acidification will negatively affect a range of calcareous taxa, the study of fishes is more limited in both depth of understanding and diversity of study species. We used new 3D micr...

A five years old male individual of Spicara flexuosa was captured by trammel nets on February 13, 2021, at 15 m depths from Black Sea region. The total length and weight were measured as 235 mm 144.06 g. This specimen is the largest that has been reported in coastal waters Turkey. Some morphometric aspects sampled picarel also given. otolith determined 0.0563 Otolith width 8044.31 μm 4596.48 μm...

T H E R E is still little known about the formation of the mammalian otolith. Work carried out on this problem many years ago (Nishio, 1926) left many questions unanswered. In the meantime considerable knowledge has been gained of the development of other calcined structures, namely, bones and teeth, and the present paper consists of a reinvestigation of the development of the otoliths of the h...
