Abstract Male swordtails in the genus Xiphophorus display a conspicuous ventral elongation of the caudal fin, the sword, which arose through sexual selection due to female preference. Females mate regularly and are able to store sperm for at least 6 months. If multiple mating is frequent, this would raise the intriguing question about the role of female choice and male-male competition in shaping the mating system of these fishes. Size-dependent alternate mating strategies occur in Xiphophorus; one such strategy is courtship with a sigmoid display by large dominant males, while the other is gonopodial thrusting, in which small subordinate males sneak copulations. Using microsatellite markers, we observed a frequency of multiple paternity in wild-caught Xiphophorus multilineatus in 28% of families analyzed, but the actual frequency of multiple mating suggested by the correction factor PrDM was 33%. The number of fathers contributing genetically to the brood ranged from one to three. -

Corresponding author: André F. Barreto-Lima, email: [email protected] Manuscript received: 2 April 2013 Abstract. We studied the activity, foraging mode and microhabitat use of Enyalius perditus in a disturbed reserve of Atlan- tic Forest in Minas Gerais, Brazil, during 2003 and 2004. We registered behavioural expressions of this species in the field for the first time. We inferred foraging modes based on distance covered, movement rates, and prey consumed by lizards. Activity was evaluated according to gender by frequency of movements per hour. This species exhibited diurnal activity, with all lizards foraging on the leaf litter, and males covered larger distances than females. The leaf litter was the micro- habitat used most often by the lizards. At dusk, E. perditus used shrubs as “perch dormitories” and refuges. There was no difference in microhabitat use between genders. AlthoughEnyalius species can be regarded as “sit-and-wait” foragers, our data showed that E. perditus can be an opportunistic forager, preying on leaf litter invertebrates, and moving about as a “cruising forager” in a disturbed forest model. -

ZooKeys 874: 31–45. https://doi.org/10.3897/zookeys.874.35618 Abstract Species checklists and dichotomous keys are valuable tools that provide many services for ecological stud- ies and management through tracking native and non-native species through time. We developed nine drainage basin checklists and dichotomous keys for 196 inland fishes of Texas, consisting of 171 native fishes and 25 non-native fishes. Our checklists were updated from previous checklists and revised using reports of new established native and non-native fishes in Texas, reports of new fish occurrences among drainages, and changes in species taxonomic nomenclature. We provided the first dichotomous keys for major drainage basins in Texas. Among the 171 native inland fishes, 6 species are considered extinct or extirpated, 13 species are listed as threatened or endangered by U.S. Fish and Wildlife Service, and 59 spe- cies are listed as Species of Greatest Conservation Need (SGCN) by the state of Texas. -
Life History Variation Along a Salinity Gradient in Coastal Marshes

A field study was conducted on natural populations of the sailfin molly Poecilia latipinna, the western mosquitofish Gambusia affinis and the least killifish Heterandria formosa col- lected from coastal marsh sites along a salinity gradient, to investigate the influence of salinity on body condition and reproductive life history traits. In brackish marsh sites male P. latipinna had the best body conditions, while females had similar body conditions across all 3 marsh types. Female P. latipinna had greater reproductive allotment and fecundity in brackish marshes, where this fish was most abundant. Specimens of G. affinis collected from fresh marsh sites had less favorable body condition, and females had lower reproductive allotment and fecundity than those collected from higher salinities. While G. affinis was more abundant in freshwater marshes than in higher salinity marshes, this higher abundance did not correspond with a better body condition or higher reproduc- tive effort, suggesting that G.
