Little Holland Tract and Wildlands Flux Study; Zooplankton, Phytoplankton, and Larval Fish Taxonomic Data, 2017-2018 This data set includes taxonomic data for zooplankton, larval fish, and phytoplankton sampled in Little Holland Tract and Liberty Island Conservation Bank, in the northern Sacramento-San Joaquin River Delta, California. Zooplankton and larval fish were collected with target specific trawl nets and phytoplankton was collected from water grabs. This data release includes all measured environmental parameters.

Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest proximity to M. occultus) form separate monophyletic clades based on sequences of two mitochondrial genes (cytochrome-b [cytb] and cytochrome oxidase subunit II [COII]). We re-evaluated the phylogenetic relationship between M. occultus and M. lucifugus based on mitochondrial sequences using an expanded dataset of cytb and COII sequences that originated from more genetically diverse specimens of M. lucifugus collected across...

In the addition to the newly described species, three previously named (nominate) species of the same genus are compared and redescribed in this same manuscript. The morphological data include both mensural (morphometric) and meristic (count) data. Synonymies are provided for all species, since many misidentifications have been made in the literature, which dates to the early 1800's.

Geologic data, compiled from published sources, include the location and characteristics of geologic contacts and faults, mapped geologic polygons, and ammonite fossils. The geologic database includes spatial feature classes that collectively contain the geologic information that are presented in the previously published map plate. The spatial data are accompanied by non-spatial tables that describe the sources of geologic information, a description of geologic map units, a glossary...
