A hydrodynamic sensory antenna used by killifish for nocturnal hunting.
The perception of sensory stimuli by an animal requires several steps, commencing with the capture of stimulus energy by an antenna that, as the interface between the physical world and the nervous system, modifies the stimulus in ways that enhance the animal's perception. The mammalian external ear, for example, collects sound and spectrally alters it to increase sensitivity and improve the de...
متن کاملAltered Behavior of Parasitized Killifish Increases Susceptibility to Predation by Bird Final Hosts
Parasites that are transmitted from prey to predator are often associated with altered prey behavior. Although many concur that behavior modification is a parasite strategy that facilitates transmission by making parasitized prey easier for predators to capture, there is little evidence from field experiments. We observed that conspicuous behaviors exhibited by killifish (Fundulus parvipinnis) ...
متن کاملDrilling Predation on Serpulid Polychaetes (Ditrupa arietina) from the Pliocene of the Cope Basin, Murcia Region, Southeastern Spain
We report quantitative analyses of drilling predation on the free-living, tube-dwelling serpulid polychaete Ditrupa arietina from the Cope Cabo marine succession (Pliocene, Spain). Tubes of D. arietina are abundant in the sampled units: 9 bulk samples from 5 horizons yielded ~5925 specimens of D. arietina. Except for fragmentation, tubes were well preserved. Complete specimens ranged from 3.1 t...
متن کاملThe comparative ecology of a killifish (Rivulus hartii) across aquatic communities differing in predation intensity
Background: Life-history theory predicts that populations experiencing different patterns of ageor size-specific mortality will evolve divergent life histories. Higher mortality can also cause indirect effects by reducing population density and increasing resources for survivors. How life histories evolve can ultimately be shaped by the interactions between the direct impact of predators on mor...
متن کاملMolecular Identification of Polychaetes Based on 18s rRNA Gene 103 7. MOLECULAR IDENTIFICATION OF POLYCHAETES BASED ON 18S rRNA GENE
Molecular tools have revolutionized the exploration of biodiversity, especially in organisms for which traditional taxonomy is difficult (Tang et al., 2012). The small subunit (SSU) 18S rRNA gene is one of the most frequently used genes in phylogenetic studies and an important marker for random target PCR in environmental biodiversity screening. 18S rDNA is a nuclear ribosomal gene, commonly re...
