Abstract Because of apparent reproductive isolation between Northern and Southern hemisphere populations the black drum Pogonius cromis , we tested hypothesis that advertisement calls from a southern population would differ known North American populations. Additionally, quantified disturbance calls, their changes with fish size sex, not previously examined in this species. Unlike most sciaenids, both sexes P. possess robust sonic muscles, produce when handled. However, only males an call...
Myelination of the peripheral nervous system requires Schwann cells (SC) differentiation into myelinating phenotype. The myelin protein-22 (PMP22) is an integral membrane glycoprotein, expressed in SC. It was initially described as a growth arrest-specific (gas3) gene product, up-regulated by serum starvation. PMP22 mutations were pathognomonic for human hereditary neuropathies, including Charcot-Marie-Tooth disease (CMT). Trembler-J (TrJ) heterozygous mouse model carrying same pmp22 point...
Length-weight relationships are commonly used in fisheries biology to convert length measures into weight and ascertain the growth characteristics related those variables. On other hand, length-weight for estimating fishes’ condition factor, these values comparing “condition”, “fatness” or “well-being” of fish (LE CREN, 1951; FROESE, 2006). The factor could reflect physiological state a fish, which is influenced by both intrinsic (gonadal development, organic reserves, presence absence food...
We analyzed the stomach contents of 2915 individuals whitemouth croaker, Micropogonias furnieri, ranging from 15.6 to 42.0 cm total length, collected a coastal lagoon in Rocha, Uruguay, during 1997–1999. A 56% (n = 1646) were found with content their stomachs. Six food items identified and classified as crustaceans (49%), polychaetes (26%), vegetal debris (15%), molluscs, juvenile fishes, unidentified contents, latter three representing less than 5% contents. Fishes displayed higher...

Picloram (PIC) is an herbicide widely used in Uruguay to control weeds, especially forest crops. In the present study, we evaluate acute toxicity and genotoxicity of formulated 24.9% PIC-based Tordon®24K on Boana pulchella tadpoles under standard laboratory conditions. test use mortality as endpoint obtained a 48-h LC50 16.5 mg/L, LOEC 14.5 NOEC 12.5 mg/L. We determined GS36 exposed sublethal concentrations 8.5 (NOEC/1.5) mg/L (NOEC) PIC using micronucleus frequency (MN) occurrence nuclear...
Paralichthys species have high commercial value and constitute a resource for demersal fisheries in the Southwestern Atlantic Ocean. Although six been described based on morphological characters Uruguayan Argentinean waters, only presence of three is accepted, being their distribution still uncertain. Genetic tools are useful identification as complement characters. This paper determines genetic morphometric variation between that inhabiting waters. The interorbital width (IN) length from...
