Lethal and Sublethal Effects of Glyphosate (Roundup® Active) to Embryos of Colombian Anurans
Acta Biológica Colombiana, 2013 Glyphosate is an herbicide widely used in agriculture, which may affect non-target species. The aim of this study was to determine the lethal (Median lethal concentration - LC50) and sublethal effects (changes on body size and development) of glyphosate (

Relationships between summer Thermal variations and cell proliferation in heterothermic vertebrates, as revealed by PCNA expression in the brain of adult Rana bergeri (Günther, 1986) [PDF]
, 2018 About the issue if the natural encephalic proliferative activities can be infl uenced by the seasonal (thermal and photoperiodic) cyclic fl uctuations in adult earth-dwelling Anamnia and poikilothermal Amniota there is a gap regarding expressly summer ...

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 ...

Interaction between spring temperature-photoperiod and experimentally induced transient cold shock influencing proliferative activity in the brain of an adult terrestrial heterothermic vertebrate, Rana bergeri (Günther, 1986) [PDF]
, 2015 The seasonal thermal cycle and correlated variations in photoperiod exert antithetical influences on the proliferation of the reserve brain stem cells, which are mostly ependymal and sub-ependymal, of adult earth-dwelling heterothermic vertebrates upon ...

The Anatomical Record, EarlyView.Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Popliteal sinus venipuncture in anurans
Journal of the American Veterinary Medical AssociationAbstract OBJECTIVE To demonstrate an underutilized, reliable, and technically simple anuran venipuncture technique by use of the popliteal sinus. ANIMALS Medium to large (> 30 g) anuran species. METHODS The animal is manually restrained using an encircling grip around the pelvic girdle. With the ventrum facing the phlebotomist, the phlebotomist
