“…Asimismo, los recuentos celulares se encontraron dentro de los rangos publicados para otras especies de anuros de distintas regiones del mundo (Glomski et al 1997, Wojtaszek & Adamowicz 2003. La relación RGB/RGR fue 1:114 (rango 1:54-222).…”

“…Esto podría deberse al período en que se realizó la recolección de ejemplares (enero), señalado por varela y Sellares (1938) como uno de los meses con menor recuento de hematíes para R. arenarum. Este patrón se repite en otras especies de anfibios, en el que se observan los mayores recuentos de eritrocitos en primavera, disminuyendo en los meses de verano, para llegar a los mínimos valores en otoño (Wojtaszek & Adamowicz 2003, Arserim & Mermer 2008. Por otra parte, si consideramos que la frecuencia de eritrocitos inmaduros (eritroblastos y PO) representa la eritropoyesis (Allender & Fry 2008), podemos decir que los ejemplares de R. fernandezae no se encuentran en un período de renovación eritrocítica ya que dicha frecuencia fue baja (0.24±0.34).…”

Recibido 12-v-2010.Corregido 15-vIII-2010. Aceptado 17-IX-2010.Abstract: Hematology and blood cell cytochemistry of Rhinella fernandezae (Amphibia: Anura) from Espinal and Delta-Islands of Paraná River, Argentina. The description of amphibian hematology is scarce and most of these studies have been done in species from North America, Asia and Europe. With the purpose to obtain basic hematological information of Rhinella fernandezae, 23 blood samples from Santa Fe and Entre Ríos natural reserves were studied. Blood of each individual was extracted by cardiac puncture and hemograms were carried out. Morphological and cytochemical description of blood cells were analyzed in slides and were inspected for extra and intra cellular parasites. Five leucocytes types were observed, being lymphocytes the predominant ones followed by basophiles. Heterophils and eosinophils were positive to PAS, Sudan B and peroxidase. The erythrocytes and its precursors were negative for cytochemical reactions. Micronuclei and nuclear alterations frequencies were scarce. No significant differences (p>0.05) were observed between sexes neither in hemograms nor in blood cells morphology. Microfilarias were the only hemoparasites found with a relative low prevalence and infection intensity. The hematological characteristics studied were similar to those reported for other amphibians, suggesting that R. fernandezae individuals present optimal nutritional and immunological status. Rev. Biol. Trop. 59 (1): 17-28. Epub 2011 March 01.

“…Toads mainly inhabit terrestrial environments, whereas frogs inhabit semi-aquatic or aquatic environments (GÜL et al 2011). The terrestrial habitat has selected a series of adaptive structures and mechanisms in frogs that have enabled them to function under conditions of changeable humidity and partial oxygen pressure in terrestrial environments (BARAQUET et al 2013, FOXON 1964, WOJTASZEK & ADAMOWICZ 2003. Second, erythrocyte size may be dependent on the level of metabolism in vertebrates (WOJTASZEK & ADAMOWICZ 2003).…”

Through our field investigation, we found that two toad species (B. gargarizans and D. melanostictus) that crawl slowly and have lower metabolic rate consume less energy than the other three species that are agile in their jumping and swimming activity.…”

“…Nevertheless, there are few studies available on Neotropical amphibian hematology (CABAGNA-ZENKLUSEN et al, 2005;CABAGNA-ZENKLUSEN et al, 2011;LAJMANOVÍCH et al, 2012), and scarce studies on anuran white blood cell morphology (ARIKAN; ÇIÇEK, 2010;. Few morphometric studies of red blood cells (BARNI et al, 1992;ATATÜR et al, 1999;WOJTASZEK;ADAMOWICZ, 2003;GRENAT et al, 2009) and white blood cells (FOXON 1964;NANO et al, 1991;TOZETTI et al, 2014) are available. To the authors' knowledge, this is the first study on white blood cell morphology in Neotropical anurans from South America.…”

Amphibians are potentially reliable and efficient bioindicators. Existing anuran white blood cell morphology studies are limited, with only a few morphometric studies available. We employed morphometric techniques to characterize leukocytes of selected Neotropical anurans from Brazil and compare our findings with the exotic American Bullfrog (Lithobates catesbeianus), genus Ranidae. We compared blood smears of 28 specimens from six different genera (Hyla, Phyllomedusa, Hypsiboas, Scinax, Physalaemus, and Proceratophrys) with samples from L. catesbeianus. Leukocyte average diameter was calculated by an image analysis software. One-way analyses of variance and Bonferroni tests were used on statistical analyses. Lymphocytes, neutrophils, eosinophils, and basophils were significantly smaller than the reference ranges reported for other amphibian genera, including Lithobathes, whereas monocyte diameters did not differ significantly between genera. This is the first study to evaluate leukocyte morphometrics of Brazilian anuran species. Our findings suggest that geographical separation could possibly influence leukocyte morphometry. Keywords: Anura. Morphometry. South America. White blood cells. ResumoAnfíbios são indicadores ambientais potencialmente confiáveis e eficientes. Estudos referentes à morfologia de leucócitos de anuros são limitados, com poucos estudos morfométricos disponíveis em literatura. O presente estudo empregou técnicas morfométricas para caracterizar leucócitos de anuros Neotropicais brasileiros selecionados e compará-los com a espécie exótica rã-touro (Lithobates catesbeianus), família Ranidae. Esfregaços sanguíneos de 28 espécimes pertencentes a seis gêneros diferentes (Hyla, Phyllomedusa, Hypsiboas, Scinax, Physalaemus e Proceratophrys) foram comparados com amostras de esfregaços de L. catesbeianus. A média do diâmetro dos leucócitos foi calculada por um software de análise de imagens. One-way e teste de Bonferroni foram utilizados para avaliação estatística. Linfócitos, neutrófilos, eosinófilos e basófilos mostraram-se significativamente menores que os valores de referência reportados em outros gêneros de anfíbios, incluindo Lithobathes; por outro lado, a média do diâmetro dos monócitos não demonstrou variação significativa entre os gêneros. Esse é o primeiro estudo de avaliação morfométrica de leucócitos em espécies de anuros brasileiros. Nossos resultados sugerem que a separação geográfica possivelmente influencia a morfometria leucocitária. Palavras-chave: Anura. Morfometria. América do Sul. Leucócitos. | 160Braz.
