Evidence of habitat fragmentation affecting fish movement between the Patos and Mirim coastal lagoons in southern Brazil

open access: yesNeotropical Ichthyology
The communication between the Patos and Mirim lagoon systems occurs via a natural channel called São Gonçalo. In 1977, a dam was built in this channel to prevent entrance of saline waters from Patos Lagoon estuary into the Mirim Lagoon.

Trophic interactions among sympatric zooplanktivorous fish species in volume change conditions in a large, shallow, tropical lake

open access: yesNeotropical Ichthyology, 2011
Significant reductions in the water volume of shallow lakes impose a restriction on species segregation promoting more interactions in the trophic relationships.

Upregulation of the Nr2f1-A830082K12Rik gene pair in murine neural crest cells results in a complex phenotype reminiscent of Waardenburg syndrome type 4

open access: yesDisease Models & Mechanisms, 2016
Waardenburg syndrome is a neurocristopathy characterized by a combination of skin and hair depigmentation, and inner ear defects. In the type 4 form, these defects show comorbidity with Hirschsprung disease, a disorder marked by an absence of neural ...

Using Nearshore Fish Communities to Evaluate Eutrophication Impact in Temperate Estuaries

open access: yesFishes
Using fishes as indicators of estuarine degradation is informative in long-term monitoring programs. Beach seine hauls were used in four estuaries that differed in their trophic and tidal status.

A function‐valued trait approach to estimating the genetic basis of size at age and its potential role in fisheries‐induced evolution

open access: yesEvolutionary Applications, 2019
Natural selection is inherently a multivariate phenomenon. The selection pressure on size (natural and artificial) and the age at which selection occurs is likely to induce evolutionary changes in growth rates across the entire life history. However, the

Stable isotope evidence for trophic overlap of sympatric Mexican Lake Chapala silversides (Teleostei: Atherinopsidae: Chirostoma spp.)

open access: yesNeotropical Ichthyology
We explore the trophic role that a diverse sympatric group of fishes in the genus Chirostoma play in a large, shallow lake in central Mexico, Lake Chapala.

Shrinkage of Inland Silverside Larvae Preserved in Ethanol and Formalin

open access: yesNorth American Journal of Fisheries Management, 2000
Length measurements of preserved larval fish are necessary in many types of larval fish surveys. If the fixative causes significant shrinkage, then the pre- served lengths cannot be used to indicate accurate live lengths. The objective of this study was to determine how preservation in two different concentrations of for- malin and ethanol affects the ...

Determination of Intrinsic Sodium in Grass-Fed Bonsmara (Bos taurus indicus) Meat

open access: yesApplied Sciences
There is a view that grass-fed beef has human health benefits coupled with better quality attributes. Yet, organic sodium in grass-fed beef remains elusive and overlooked in meat processing.
