El albinismo en Pelobates cultripes ha sido recientemente descrito por BOSCH (1991) sin que existan citas anteriores o nuevos hallazgos hasta la fecha.
Applying the UDA‑ODA discrimination technique to a herpetological association: the case of the Middle Palaeolithic site of El Salt (Alcoi, Spain)
2022
AbstractEl Salt (Middle Palaeolithic; Alcoi, Spain) is a key site for understanding the disappearance of Neanderthals in the eastern Iberian Peninsula, a process that is observed along its stratigraphic sequence. To improve our understanding of the palaeoclimatic context in which this process took place, we applied the UDA-ODA discrimination technique to the fossil herpetological assemblages from Stratigraphic Units (SU) Xb (52.3 ± 4.6 ka) and V (45.2 ± 3.4/44.7 ± 3.4 ka). This method is based in the application of an ecological criterion, the maximum altitude of each species on each Iberian range, to discern and remove those areas that do not meet their ecological requirements (UDA) from t…
Recensione a: NIVARDUS GANDENSIS, Ysengrimus, Libro I, a cura di Fr. Stella, Pisa 2009 (in «Maia», n.s., 63,2, 2011)

Recensione all'ediz., con trad. ital. e commento, del libro I dell'«Ysengrimus» attribuito a Nivardo di Gand, poema epico-animalesco del XII sec., curata da Francesco Stella e pubblicata nel 2009 dalla casa editrice Pacini di Pisa.
Situación de las poblaciones del Galápago europeo (Emys orbicularis, L., 1758) y el Galápago leproso (Mauremys leprosa, Schweigger, 1812) en la provi…
2000
Se analiza la situación actual de las poblaciones de Emys orbicularis y Mauremys leprosa en Castellón, aportando datos sobre su distribución en cuadrículas UTM de 10 km de lado. E. orbicularis está presente en 11 localidades, todas ellas de la franja litoral. En cambio, M. leprosa es exclusiva de ríos del interior de la provincia, estando presente al menos en seis puntos. La presencia de esta especie fue independiente de los valores de pH, conductividad o salinidad, mientras que E. orbicularis aparece asociada a aguas salobres y de conductividad elevada. Se estudió igualmente la distribución de Trachemys scripta como especie competidora, confirmándose la presencia en cuatro localidades. -- …
Helminths of some lizards of the Iberian Peninsula: bioindicators of the ecology of their hosts.
2021
Parasitological studies carried out for more than three decades have been compared in twelve of the species of lizards that inhabit Iberian Peninsula. The species studied exhibit different ecological strategies in distinct aspects of their way of life. The working hypothesis is that these different ecological characteristics of these hosts will condition the quality and quantity of their helminth communities. Several parameters of host helminth faunas have been compared, such as prevalence, intensity and abundance of infection, and Brillouin diversity index in order to establish similarities and differences between the parasitic communities of the different hosts. Indeed, there are notable …
Serpientes y helmintos parásitos en el este peninsular español: la influencia del hábitat y el modo de vida en la helmintofauna de los ofidios ibéric…
2021
Se han analizado helmintológicamente una serie de ejemplares de ofidios terrestres del este peninsular ibérico y los datos obtenidos se han comparado con los de otras serpientes ibéricas y europeas. Se ha detectado una notable pobreza de la helmintofauna de estos ofidios que se explica en términos de sus características bioecológicas, principalmente la estrategia de alimentación y la ocupación de hábitats secos. Snakes and parasitic helminths in Eastern Spain: the influence of habitat and lifestyle on the helminthfauna of Iberian snakes. A number of specimens of terrestrial snakes from the east of the Iberian Peninsula have been helminthologically analyzed and the obtained data were compare…
Dominància i ocupació de l'espai en grups de primats no-humans: un model basat en conducta adaptativa
2007
L'estructura jeràrquica és una de les característiques fonamentals de les societats de primats, que condiciona en gran mesura el comportament dels individus que conviuen al grup. Quines lleis regeixen la formació i l'estructura d'aquestes jerarquies? Per què en determinats grups els subjectes més dominants se situen al centre del grup i en uns altres de la mateixa espècie no? En el camp de la conducta animal s'han proposat múltiples hipòtesis, però no n'hi ha cap que siga totalment satisfactòria, ja que a causa de les múltiples variables que hi infl ueixen, és difícil desplegar una teoria que explique tota la complexitat que s'observa empíricament. La nostra proposta d'estudi es basa en l'e…
Un Churel Mandir in Gujarat. Note sulla diffusione delle rappresentazioni della figura della strega in India
2021
The churels are figures of the folk imagery of a vast area of South Asia. They, commonly identified with witches, are spirits of women who died during pregnancy or childbirth, and who return to the world of the living, possessing them. The aim of this study is to provide an interpretative analysis of the representations of the churels and of the ambiguous climate that has been created around these figures in recent decades in India. A reflection on the power of the representations of the churels throughout history up to present-day India could be considered a key to penetrating the dense network of relationships and reinventions, but also of divergences and contradictions, sometimes with tr…
Il culto dei gatti in India. Continuità ed evoluzione di credenze e pratiche religiose dall’India vedica all’India contemporanea
2019
Cat as an animal is a sporadic presence in Vedic mythology and Brahmanic works on rituals, while it appears in a few cult practices of contemporary popular religiosity in India. This article holds that in Indian devotional practices, the cat is conceived as an animal with an ambiguous nature. It also suggests that the cat cult is linked with the need to tame chaos, violence, and con$ict, and to place them in a controlled, orderly, and pacified cosmos. To understand these phenomena, this article studies, from a multidisciplinary perspective, contemporary religious practices in the light of the Indian tradition, and suggests that the cat cult was subject to substantial Brahmanization.
Una forma leggiadra. Simboli sessuali dell'altalena in India nel rito del mahavrata e in alcune pratiche contemporanee
2022
In the grammar of rituals described in Vedic texts, the swing was an object whose meanings referred to the propitiation of fertility and solar symbolism. Although its use remains in various contemporary festive contexts, its meaning has been differently defined. By analyzing the passages from works belonging to the ancient religious literature, this article examines the description of the swing’s construction and the rite performed on it by the officiant named hotr. Such an approach allows us to focus on the symbolic elements related to the swing in one of the focal points of the sequence of the mahavrata ceremony. Through a diachronic investigation and considering the data from the compara…
