Survival and some physiological responses to freezing were investigated in three European water frogs ( Rana lessonae, Rana ridibunda, and their hybridogen Rana esculenta). The three species exhibited different survival times during freezing (from 10 h for R. lessonae to 20 h for R. ridibunda). The time courses of percent water frozen were similar; however, because of the huge differences in body mass among species (from 10 g for Rana lessonae to nearly 100 g for Rana ridibunda), the ice mass accumulation rate varied markedly (from 0.75 ± 0.12 to 1.43 ± 0.11 g ice/h, respectively) and was lowest in the terrestrial hibernator Rana lessonae. The hybrid Rana esculenta exhibited an intermediate response between the two parental species; furthermore, within-species correlation existed between body mass and ice mass accumulation rates, suggesting the occurrence of subpopulations in this species (0.84 ± 0.08 g ice/h for small R. esculenta and 1.78 ± 0.09 g ice/h for large ones). Biochemical analyses showed accumulation of blood glucose and lactate, liver glucose (originating from glycogen), and liver alanine in Rana lessonae and Rana esculenta but not in Rana ridibunda in response to freezing. The variation of freeze tolerance between these three closely related species could bring understanding to the physiological processes involved in the evolution of freeze tolerance in vertebrates.

Atrial Natriuretic

The localization of atrial natriuretic factor (ANF)-like immunoreactivity in the central nervous system of the frog Rana ridibunda was examined by the indirect immunofluorescence technique, using an antiserum against synthetic ANF (Arg101-Tyr126). Immunoreactive cell bodies were principally found in the dorsal and medial pallium, the medial septal nucleus, the ventrolateral and anteroventral areas of the thalamus, the lateral forebrain bundle, the posterolateral thalamic nuclei, the preoptic nucleus, the dorsal infundibular nucleus, and the anteroventral tegmentum nucleus of the mesencephalon. Numerous cell bodies and a very dense fiber bundle were visualized in the interpeduncular nucleus. All the areas mentioned above contained a high density of immunoreactive fibers. In addition, the amygdala, the infundibular nucleus, the median eminence, and most of the areas of the mesencephalon contained a moderate number of ANF-positive nerve processes. In the frog pituitary, fibers and nerve terminals were found in the peripheral zone of the neural lobe. The intermediate and anterior lobes of the frog pituitary were totally devoid of ANF immunoreactivity. These results indicate that ANF-like material is widely distributed in the frog brain and that ANF may be involved in various brain functions including neuroendocrine regulations.

Se presenta el catálogo de los anfibios y reptiles de Marruecos conservados en el Museo Nacional de Ciencias Naturales de Madrid (MNCN-CSIC) y se destaca la especial relevancia de las contribuciones realizadas por dos expediciones históricas para el conocimiento herpetológico de la región. Ambas expediciones sumaron un total de 31 especies colectadas principalmente en las regiones de Essaouira, Tánger y Ketama. Se constata la presencia en la colección de los ejemplares que representaron las primeras citas de Cerastes vipera y Scincus albifasciatus en Marruecos. Asimismo, alberga las series tipo de Rana ridibunda riodeoroi, Psammodromus algirus ketamensis y Salamandra algira tingitana. Los especímenes colectados en tiempos históricos conservados en colecciones científicas ofrecen una valiosa información para identificar cambios sufridos por las comunidades biológicas y diseñar medidas de conservación de la biodiversidad.

The type of tissue present at the point of amputation determines scarring or regeneration in the digits of Rana ridibunda. Scarring occurs when nonskeletal tissues proliferate; this is particularly true at the level of the proximal diaphysis, after periosteal resorption, between phalanges when the cartilage is intact in the articulation, and occasionally, at the level of the distal diaphysis when the reaction of the fibroblasts is intense. Regeneration occurs when skeletal tissues proliferate from the cartilages of either the epiphysis or the articulation, or from the periost. In such cases, centers of chondrogenesis develop into a cartilaginous axis that transforms into bone after 7 to 12 months. Nonskeletal conjunctive tissues (subcutaneous tissue, derma, synovial membrane) evolve into mesenchymal conjunctive tissue that will eventually reconstitute the structures from which it came originally.[Journal translation]
