Synonymies, diagnoses, descriptions, illustrations, an identification key and meristic frequency tables are provided for all species of Lonchopisthus. Most of the skeletal anatomy of L. higmani is also illustrated. A new jawfish, Lonchopisthus ancistrus n. sp., is described from the Gulf of Mexico and off Honduras based on 21 specimens 41‒89 mm standard length (SL). It differs from other congeners by the following combination of characters: posterior end of maxilla strongly hooked; membrane connecting maxilla and premaxilla and inner membrane covering posterior part of dentary pale; segmented dorsal-fin rays 11–13, with unbranched rays 2–5; longitudinal body scale rows 33‒39; and very long pelvic fins, 39.4‒75.3...

This dataset contains six individual tabular data files. These tabular data files contain measurements of aquatic habitat features and stream channel geomorphology from 20 sites in the Piedmont and Upper Coastal Plain physiographic regions of South Carolina. Specifically, the dataset titled "bedform_slope" contains enumeration of occurrence of bedforms, or macro-habitat features, and streambed and culvert bottom slopes. The dataset titled "culvert_characteristics" contains measurements and descriptions of the culverts. The dataset titled "large_woody_debris" contains measurements and classification of individual pieces of wood included in the assessment. The dataset titled "site_level_information" contains location...

The dataset is a composite of morphological data used in the description of a new species of marine fish, Trachinotus macrospilus (Teleostei: Carangidae), endemic to the Marquesas Islands of the Indo-West Pacific. 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.

Data represent dependent and independent variables used in logistic modeling for a study entitled "Evaluating Establishment Success of Non-native Fishes Introduced to Inland Aquatic Habitats of Tropical Pacific Islands." The phases of invasion of nonnative species are transport, introduction, establishment, and spread. To understand likelihood of establishment of species moved to new regions, investigators often use analytical methods that include life-history attributes, ecophysiological parameters, distributional factors, propagule pressure, introduction pathways, and other salient features that contribute to successful establishment. Introductions that fail to result in establishment are often unknown. In this...
