This project examines the use of the 16S locus to amplify neotropical freshwater fishes native to Western Ecuador in a newly created 16S reference library for DNA barcoding and eDNA metabarcoding applications. Among the orders Characiformes, Siluriformes, Cichliformes, Gobiiformes, Cryprinodontiformes, Gymnotiformes, and Perciformes, a compendium of 105 specimens were sequenced, with 43 representing new 16S sequences previously unavailable on Genbank.

Animals are considered to possess personalities when individuals differ in behavior, and these differences are consistent between situations. Several studies have identified personalities in diverse groups but less is known about personality variation between the sexes. In this study, we examined variation in two key personality traits (boldness, activity) in female and male purple marsh crabs (Sesarma reticulatum) using a semi-field approach. Specifically, we measured boldness and activity on two consecutive days using the same behavioral assays during each time point. Consistency (personality) was determined using Kendall’s coefficient of concordance based on Spearman correlation coefficients for each behavior. …

Naticid gastropods are common predatory mollusks in marine systems where they feed on bivalve mollusks. Predation involves boring a hole through the shell of the prey, which provides the opportunity for beach collections of shells to be used to determine feeding preferences of predators in nature. We examined whether naticids exhibited preferences for prey size, valve side (left vs. right) and valve site (location on the shell) and whether these preferences differed between prey species (Mulinia lateralis, dwarf surf clam; Anadara brasiliana, incongruous ark clam). Random samples of A.brasiliana and M.lateralis were collected from Otter Island, …
