Advancing Genetic Stock Identification of Leatherback Turtles From Foraging Grounds in the Southwest Atlantic: Insights From Nuclear DNA (nDNA) Analysis. [PDF]

Ecol Evol
Genetic Stock Identification (GSI) of 78 stranded or incidentally caught leatherbacks from feeding grounds off the coasts of Argentina and Uruguay was genotyped with 15 microsatellite markers. Assignment analysis results indicated that 92% of leatherbacks in this region originated from Ghana and Gabon, with smaller contributions from the Northwest ...

Landscape Genomics and Evolutionary History of <i>Megamelus scutellaris</i>, a Biocontrol Agent of the Invasive Water Hyacinth (<i>Pontederia crassipes</i>). [PDF]

Evol Appl
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

Weight-Length Ratio of Piranhas <i>Serrasalmus</i> (Characiformes, Serrasalmidae) in Bolivia: Relationships to Molecular Divergence and Maximum Size? [PDF]

Ecol Evol
This study presents WLRs of nine piranha or palometa fish species of genus Serrasalmus present in the Amazon and La Plata basins of Bolivia and compares differences with genetic divergence (mtDNA COI locus) and the observed maximum size. All species showed an exponential (power type) growth pattern, and all WLRs were significantly different among all ...

First record of Aedes aegypti (L.) (Diptera: Culicidae) infected by the parasite Ascogregarina culicis (Ross) (Apicomplexa: Lecudinidae) in Argentina [PDF]

, 2005
n a survey for parasites and pathogens of Aedes aegypti conducted in La Plata, Argentina, an aseptate gregarine was found parasitizing larvae, pupae and adults of this mosquito species. This gregarine species was identified as Ascogregarina culicis based

Spiroxys contortus (Rudolphi, 1819) and Hedruris orestiae (Moniez, 1889) in Argentine turtles [PDF]

, 2016
Knowledge of parasites in turtles is scarce,particularly with regard to freshwater turtles of SouthAmerica. Here, we describe the association of Spiroxyscontortus (Rudolphi, 1819) in Phrynops hilarii (Duméril& Bibron, 1835) and S.

Ecology of the non-native snail Sinotaia cf quadrata (Caenogastropoda: Viviparidae). A study in a lowland stream of South America with different water qualities [PDF]

, 2017
Sinotaia quadrata is a snail native from Asia recorded for the first time in South America in 2009 in central Argentina. In 2015, this species was also found in a lowland stream with different water qualities. Our aims were to contribute to the knowledge

Evaluation of Mesocyclops annulatus (Copepoda: Cyclopoidea) as a control agent of Aedes aegypti (Diptera: Culicidae) in Argentina. [PDF]

, 2004
We evaluated the potential of Mesocyclops annulatus as a control agent of Aedes aegypti in La Plata city (Argentina). Mosquito larval survivorship due to predation by these copepods was estimated at weekly intervals during the oviposition period of A ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
