A study on European anchovy (Engraulis encrasicolus) swimbladder with some considerations on conventionally used target strength

tailieu.vn

Effective quantification of the distribution and abundance of small pelagic fish such as anchovy and sardines is generally carried out by means of hydroacoustic studies (Simmonds and MacLennan, 2005). In principle, the method relies on integration of the echo intensity reflected by acoustically detectable fish schools (MacLennan, 1990). On the other hand, what determines the backscattering capacity of a fish...

Histological and histochemical study on the mesonephric kidney of Pelophylax bedriagae (Anura: Ranidae)

tailieu.vn

Histological and histochemical study on the mesonephric kidney of Pelophylax bedriagae (Anura: Ranidae). In vertebrates, the kidneys play a prominent role in the regulation of body fluid (Junqueira and Carneiro, 2006). The functional and structural unit of the kidney is the nephron, which is generally composed of the renal corpuscle, proximal and distal tubules, Henle’s loop, and collecting tubule and...

First record of the genus Spilomyia (Diptera, Syrphidae) from the Oriental region

tailieu.vn

First record of the genus Spilomyia (Diptera, Syrphidae) from the Oriental region. The genus Spilomyia Meigen, 1803 currently includes 38 species, mainly distributed in the Holarctic region with a few species occurring in the Neotropics (van Steenis, 2000). Despite their large size (9–22 mm) and widespread distribution, Spilomyia species are often overlooked in the field even by experienced collectors because...

Hibernation perturbs the number of hemocytes and causes hematological turnover: basal traits to understand season-dependent physiological variations in Helix pomatia (Gastropoda: Helicidae)

tailieu.vn

Hibernation perturbs the number of hemocytes and causes hematological turnover:. A great success in the evolution of animal behavior and physiology is the ability to survive seasonally unfavorable conditions, especially when it comes to variable and extremely low temperatures (Roots, 2006). Life activities of the gastropods depend on environmental factors throughout the whole year. The formation of the calcareous epiphragm,...

(Copepoda: Harpacticoida: Ameiridae) with the first report of the genus Pseudoameiropsis Pallares, 1982 outside of the South Atlantic Ocean. The family Ameiridae Boeck, 1865, with more than 400 species accommodated in 50 genera, is one of the most speciose harpacticoid families, which can be found in a wide range of habitats from marine to freshwater (Boxshall and Halsey, 2004.

Comalcandona gibsoni sp. nov. (Ostracoda, Candonidae) from Comal Spring, Texas, USA

tailieu.vn

Thalassocypridinae Hartmann and Puri, 1974) is known to have one of the widest distributions among ostracods (Danielopol et al., 2011). Of these, Candoninae, with about 510 ostracod species (Martens and Savatenalinton, 2011), is the largest subfamily in the world. The successful wide-ranging adaptation and distribution of these species may be related to the long evolutionary background of the subfamily, which...

Trophic analysis and parasitological aspects of Liolaemus parvus (Iguania: Liolaemidae) in the Central Andes of Argentina. Castillo et al., 2017b). The “sit-and-wait” strategy is employed by opportunist species that consume a smaller number of larger solitary prey (Pianka, 1966. Cox et al., 2007;. Background data have shown that populations (lizards of the same species occupying a particular geographic area) are...

Efficiency of pitfall traps and snap traps in small terrestrial mammals depends on their diet composition

tailieu.vn

Efficiency of pitfall traps and snap traps in small terrestrial mammals depends on their diet composition. Small terrestrial mammals are of extraordinary importance in most terrestrial ecosystems (Barrett and Peles, 1999. Weldy et al., 2019). At the same time, small terrestrial mammals are among the vertebrates that are most difficult to trace (Zejda, 1991). Different types of traps (snap traps,...

In mammals, the sex-determining region of the Y chromosome (SRY) initiates male sex determination, which is a testis-determining factor (Koopman et al., 1990. In contrast, Sry does not exist in nonmammalian vertebrates (Tiersch et al., 1991. Denny et al., 1992). In previous studies, genetic sex determination and environmental sex determination were performed in a range of vertebrate amphibian, reptile, and...
