• Shift of the Vegetal Pole Area of Full-Grown Oocytes Toward the Ovulatory Site of the Ovary in the Medaka Fish, Oryzias latipes (Beloniformes: Adrianichthyidae).

  Authors:Takashi Iwamatsu, Shoji Oda, Hirokuni Kobayashi, Lynne R. Parenti, and Yasuhisa KobayashFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 20205,685 words Report 1380LThis study presents novel findings on the dynamics of growing oocytes in the ovary of the medaka fish, Oryzias latipes. In the ovary of mature females, all follicles are anchored tightly to the abdominal ovarian rete via...

• Seasonally Driven Sexual and Asexual Reproduction in Temperate Tethya Species.

  Authors:Megan R. Shaffer, Simon K. Davy, Manuel Maldonado, and James J. BellFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 202012,659 words Article 1360LMarine organisms that rely on environmental cues for reproduction are likely to experience shifts in reproductive phenology and output due to global climate change. To assess the role that the environment may play in the...

• Red Coloration in an Anchialine Shrimp: Carotenoids, Genetic Variation, and Candidate Genes.

  Authors:Ryan J. Weaver, Bryson K. Gonzalez, Scott R. Santos, and Justin C. HavirdFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 20208,455 words Article 1290LRed coloration is a widely distributed phenotype among animals, yet the pigmentary and genetic bases for this phenotype have been described in relatively few taxa. Here we show that the Hawaiian endemic anchialine shrimp...

• Direct Observation of the Setular Web That Fuses Thoracopodal Setae of a Calanoid Copepod into a Collapsible Fan.

  Authors:George Von Dassow and Richard B. EmletFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 20203,543 words Report 1390LCopepods are numerically dominant planktonic grazers throughout the waters of Earth, preyed upon in turn by a wide diversity of pelagic animals (1, 2). These crustaceans swim and feed using cuticle-covered, segmented,...

• Thermal Range and Physiological Tolerance Mechanisms in Two Shark Species from the Northwest Atlantic.

  Authors:Abigail B. Bockus, Christopher J. Labreck, Jodi L. Camberg, Jeremy S. Collie, and Brad A. SeibelFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 202010,427 words Report 1410LSpiny dogfish (Squalus acanthias) and smoothhound (Mustelus canis) sharks in the northwest Atlantic undergo seasonal migrations driven by changes in water temperature. However, the recognized thermal habitats of these...

• Phenotypic Variation in Growth and Gene Expression Under Different Photoperiods in Allopatric Populations of the Copepod Tigriopus californicus.

  Authors:Daniel T. Schneck and Felipe S. BarretoFrom:The Biological Bulletin (Vol. 238, Issue 2) Peer-Reviewed

  Apr. 20208,396 words Article 1320LDaylength is a major environmental condition that varies seasonally and predictably along a latitudinal cline, where higher latitudes exhibit greater ranges in total daylengths. Generally, the circadian clock acts as a...
