  • Hatching Success Affects the Timing of Spawning by the Intertidally Spawning Puffer Takifuguniphobles

As the season progresses, however, the tlming of spawnlng cvents pro- gressively sh~ftsfrom just before to just after the new or full moon. This study explains why there is the seasonal shift In the timing of spawning from the viewpoint of larval hatching success. Larval sampling in the field and rearlng experiments in the laboratory indicated that hatching occurred only when the nighttime h~ght~des flood the stranded eggs. Accord~ngto ambient temperatures, incubation penods tended to be shorter as the season progressed. Therefore. spawning occurs prior to the peak spnng t~des(dates of new and full moons) early In the season to allow sufficient t~mefor completion of embryo- logical devclopment prior to the occurrence of neap tides, which may not flood the intertidal spawnlng site. The relationship between the zone of stranded eggs and the tidal reglme at the site indicated that most of the completely developed embryos can be successfully submerged by nighttime high tides

  • UNIVERSITY of CALIFORNIA Los Angeles Introgressive Hybridization Among Gulf of California Endemic Species of the Genus Colpicht
    UNIVERSITY OF CALIFORNIA Los Angeles Introgressive hybridization among Gulf of California endemic species of the genus Colpichthys in relation to environmental change in the Colorado River Delta A thesis submitted in partial satisfaction of the requirements for the degree Master of Science in Biology by Long Fung Lau 2017 © Copyright by Long Fung Lau 2017 ABSTRACT OF THE THESIS Introgressive hybridization among Gulf of California endemic species of the genus Colpichthys in relation to environmental change in the Colorado River Delta by Long Fung Lau Master of Science in Biology University of California, Los Angeles, 2017 Professor David K. Jacobs, Chair The unique habitats of the Northern Gulf of California are home to many endemic vertebrate and invertebrate taxa. Owing to their limited geographic range, these taxa are often vulnerable to extinction. Located at the tip of the Northern Gulf is the Colorado River Delta. Upstream damming and water diversions in the past century have turned the Delta into an inverse estuary. The resulting rise in salinity and environmental impacts in the region have raised concerns for the local endangered fauna. Among these is the endemic silverside fish, Colpichthys hubbsi, which is narrowly restricted to the tidal channels within the Delta. Its sister species, Colpichthys regis, inhabits lagoons and estuarine channels on both sides of the Gulf. The two species share a region of syntopy at the southwestern edge of the Delta where hybridization is suspected to occur. Combining phenotypic and molecular data, this study shows evidence for introgressive ii hybridization between C. regis and C. hubbsi. While we find no evidence for recent population decline in C.

  • Introgression Between Ecologically Distinct Species Following Increased Salinity in the Colorado Delta- Worldwide Implications for Impacted Estuary Diversity
    Introgression between ecologically distinct species following increased salinity in the Colorado Delta- Worldwide implications for impacted estuary diversity Clive L.F. Lau and David K. Jacobs Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA, United States of America ABSTRACT We investigate hybridization and introgression between ecologically distinct sister species of silverside fish in the Gulf of California through combined analysis of morphological, sequence, and genotypic data. Water diversions in the past century turned the Colorado River Delta from a normal estuary to a hypersaline inverse estuary, raising concerns for the local fauna, much of which is endangered. Salinity differences are known to generate ecological species pairs and we anticipated that loss of the fresher-water historic salinity regime could alter the adaptive factors maintaining distinction between the broadly distributed Gulf-endemic Colpichthys regis and the narrowly restricted Delta-endemic Colpichthys hubbsi, the species that experienced dramatic environmental change. In this altered environmental context, these long- isolated species (as revealed by Cytochrome b sequences) show genotypic (RAG1, microsatellites) evidence of active hybridization where the species ranges abut, as well as directional introgression from C. regis into the range center of C. hubbsi. Bayesian group assignment (STRUCTURE) on six microsatellite loci and multivariate analyses (DAPC) on both microsatellites and phenotypic data further support substantial recent admixture between the sister species. Although we find no evidence for recent Submitted 21 September 2017 population decline in C. hubbsi based on mitochondrial sequence, introgression may be Accepted 27 October 2017 placing an ancient ecological species at risk of extinction.

  • Absence of Countergradient and Cogradient Variation in an Oceanic Silverside, the California Grunion Leuresthes Tenuis
    Vol. 461: 175–186, 2012 MARINE ECOLOGY PROGRESS SERIES Published August 8 doi: 10.3354/meps09802 Mar Ecol Prog Ser Absence of countergradient and cogradient variation in an oceanic silverside, the California grunion Leuresthes tenuis Elizabeth E. Brown*, Hannes Baumann, David O. Conover School of Marine and Atmospheric Sciences, Stony Brook University, Stony Brook, New York 11794-5000, USA ABSTRACT: Spatial adaptations that maximize a species’ fitness in its local environment, particu- larly in the form of countergradient variation (CnGV = genotypic influences counteract environ- mental effects on trait variation) and cogradient variation (CoGV = genotypic influences accentu- ate environmental plasticity), have been documented in many estuarine and anadromous fishes. However, their prevalence in more oceanic fishes, where extensive gene flow and reduced envi- ronmental selection may preclude local adaptation, remains unclear. If oceanic species lack genetic structure, they may be limited in their ability to adapt to global climate change. We exam- ined the potential for adaptation in oceanic fishes by testing whether an oceanic silverside, the California grunion Leuresthes tenuis, displays CnGV in growth capacity and CoGV in vertebral number across a latitudinal gradient as found in estuarine silversides. Common garden experi- ments revealed that reaction norms for growth in response to temperature differed little among 3 L. tenuis populations from different latitudes. Growth rates of wild adult L. tenuis measured from scale analysis suggested that growth may be slightly faster at more southern latitudes, likely due to environmental variation. Mean vertebral number in wild L. tenuis, determined from radio- graphs, were nearly identical for all populations. Overall, our results did not provide evidence for spatial adaptations in these traits of L.
