Photoperiod and feeding behavior of the Antarctic fish Notothenia rossii (Perciformes: Nototheniidae) and functional morphology of chemical and visual sensory structures used in foraging Zoologia
Donatti,Lucélia; Zaleski,Tânia; Calil,Patrícia; Fanta,Edith.
The influence of photoperiod on the ability of Notothenia rossii Richardson, 1844 to detect prey was studied experimentally. In 12L/12D there was the highest number of individuals stimulated visually and chemically while in 24D chemical perception was the same as that observed in 12L/12D, the latter being lower than in 24L. The ultrastructure of chemo- and photo-sensory structures, involved in the detection of food, was studied. The photoreceptor cells of the retina are single and double cones, and rods. Taste buds were concentrated in the central part of upper and lower lips. Their shape is even, but the size is variable. The olfactory rosette has a sensory and a non-sensory epithelium, being rich in different mucosubstances. The conclusion was that in...

Morphological and morphometric variability of the squid Lolliguncula brevis (Mollusca: Cephalopoda) in Brazilian waters: evidence for two species in the western atlantic? Anais da ABC (AABC)
Zaleski,Tânia; Perez,José A. Angel; Gandara-Martins,Ana luiza.
Morphological and morphometric variability of the small-sized coastal squid Lolliguncula brevis was assessed along the largest part of its latitudinal range in the southern hemisphere, off the Brazilian coast (8º S - 27º S). A general homogeneity in form was found throughout the entire latitudinal range. In terms of body proportions, no latitudinal gradients were evident, but a few local "morphotypes" could be distinguished. The distinctive egg mass morphology, and size and form features, including a hectocotylus 20-40% longer than the opposing ventral arm and the presence of suckers on the buccal membrane, indicated that Lolliguncula from northern and southern hemispheres might comprise two different taxa.

Population structure of Phalloceros caudimaculatus (Hensel, 1868) (Cyprinodontiformes, Poeciliidae) collected in a brook in Guarapuava, PR BABT
Wolff,Luciano Lazzarini; Hreciuk,Ericsson Ricardo; Viana,Douglas; Zaleski,Tânia; Donatti,Lucélia.
The population structure of Phalloceros caudimaculatus was studied in a brook (sites A and B) existing in the CEDETEG - Guarapuava/PR. Fourteen length classes of 3 mm amplitude were defined for P. caudimaculatus. The widest length amplitude and the average and maximum sizes were observed in females. Females were significantly more predominant in the whole sample and more frequent in all length classes. The sexual proportion data, showed that the number of females was superior to that of males throughout most of the year. Young occurrence peaks were registered in November and March. Pregnant females were present from March to April, from July to August and in January, characterizing the reproductive season. At sampling site A, a higher occurrence of...

Population structure and somatic indexes of Hypostomus cf. ancistroides (Siluriformes, Loricariidae) collected from the Bonito river, Ivaí river basin, Turvo, Paraná BABT
Viana,Douglas; Wollf,Luciano Lazzarini; Zaleski,Tânia; Romão,Silvia; Bertoldi,Gustavo; Donatti,Lucélia.
This study aimed to provide information about the population structure and somatic index of Hypostomus cf. ancistroides collected from the Bonito river, located in the Ivaí river basin. The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length) predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1-30.0cm). The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The...
