AbstractGregarious larval settlement, a phenomenon in which cues associated with conspecifics induce larval settlement, plays a role in the growth of existing aggregations of many aggregation-forming sessile marine invertebrates. The format...
Confirmation of Spurilla braziliana (Mollusca: Nudibranchia) in the Southwest Atlantic: Morphology, Phylogeny, and Distribution [0.03%]

Ezequiel A Fiotto et al.
AbstractNudibranchs of the genus Spurilla (Aeolidiidae) are currently represented worldwide by five species: S. braziliana, S. croisicensis, S. dupontae, S. neapolitana, and S. sargassicola. Two of these, S. neapolitana and S. braziliana, h...
Tyramine (Dopamine) β-Hydroxylase and Octopamine Immunoreactivities in the Central Nervous System of the Snail Lymnaea stagnalis [0.03%]
Griffin A Beach,Alexander P Young,Russell C Wyeth et al.
Griffin A Beach et al.
AbstractResearch suggests that tyramine and octopamine have complementary distributions and roles in invertebrates somewhat analogous to those of norepinephrine and epinephrine in vertebrates. Interestingly, these groups of neurotransmitter...
Cuttlefish Turn Slowly but Tightly with Directional Flexibility Using Short Vortex Ring Jets [0.03%]

AbstractCephalopods, such as squids and cuttlefishes, play an integral role in food web dynamics as both prey and predator, whereby proficient turning is required for successful predator avoidance and prey capture. However, surprisingly lit...
The Armor of a Keystone Predator: Intraspecific Aboral Spine Variation in the Ochre Sea Star, Pisaster ochraceus (Brandt) [0.03%]
关键顶端捕食者铠甲：沿阶草海星（Pisaster ochraceus）种内底面棘刺变化

Angela J Jones
AbstractThe abrasive, high-impact environment of rocky intertidal zones produces important abiotic stressors that many calcifying organisms are armored against. The ochre sea star (Pisaster ochraceus), a slow-moving but ecologically importa...
Light Sensitivity of the Arctic Copepod Metridia longa during Midnight Sun and Polar Night [0.03%]
午夜太阳和极夜期间的北极桡足类动物Metridia longa的光敏感性

Meaghan Lightfoot
AbstractThe high Arctic is defined by an annual light regime ranging from 24-h light (Midnight Sun) to 24-h dark (Polar Night). Light acts as an important cue for marine zooplankton, influencing their orientation and vertical migration, pre...
Photophores in Stomiiform Fishes: Morphology, Distribution, and Putative Behavioral Roles [0.03%]

Ashley N Marranzino
AbstractBioluminescence is a common feature of the fishes inhabiting the dimly lit waters of the deep sea and is thought to play roles in prey attraction, predator avoidance, communication, and counterillumination. Stomiiformes, the most ab...
The Energy Cost of RNA Synthesis in Sea Urchin Embryos (Strongylocentrotus purpuratus) [0.03%]
海胆胚胎（Strongylocentrotus purpuratus）中RNA合成的能量成本

Francis T C Pan
AbstractDefining the metabolic cost of specific biochemical processes is key to understanding strategies of energy (ATP) allocation. In this study, we determined the energy cost of RNA synthesis and the allocation of the ATP pool to this bi...
Do Structural Changes in the Macrobenthic Community Drive Differences in the Reproductive Performance of the Pea Crab Austinixa patagoniensis? [0.03%]
底栖宏生物群落结构变化驱动的豌豆蟹Austinixa patagoniensis繁殖表现差异研究？

Ana Paula Andrieu
AbstractFecundity and egg size vary among females, depending on environmental conditions experienced by mothers, known as maternal effects. Temperature, salinity, food availability, competition, and predation can influence maternal allocati...
I Am Your Father: Investigating the Genetic Mating System in the Antarctic Sea Spider Nymphon australe [0.03%]
