Identification, characterization and analysis of expression of genes encoding arylalkylamine N-acetyltransferases in the pea aphidAcyrthosiphon pisum
2013
Most organisms exhibit some kind of rhythmicity in their behaviour and/or physiology as an adaptation to the cyclical movements of the Earth. In addition to circadian rhythms, many organisms have an annual rhythmicity in certain activities, such as reproduction, migration or induction of diapause. Current knowledge of the molecular basis controlling seasonal rhythmicity, especially in insects, is scarce. One element that seems to play an essential role in the maintenance of both circadian and seasonal rhythms in vertebrates is the hormone melatonin. In vertebrates, the limiting enzyme in its synthesis is the arylalkylamine N-acetyltransferase (AANAT). Melatonin is also present in insects bu…
Photoperiodic effects on diapause-associated gene expression trajectories in EuropeanLeptinotarsa decemlineatapopulations
2014
Behavioural and physiological changes during diapause, an important strategy of insects for surviving harsh seasonal conditions, have been intensively studied. The genetic and molecular mechanisms underpinning diapause development are less well known. We took a candidate gene approach to study prediapause gene expression patterns in the Colorado potato beetle (Leptinotarsa decemlineata), an invasive insect that has rapidly spread northwards to high seasonality environments. Newly eclosed beetles originating from southern (Italy) and northern (Russia) Europe were reared under short- [12 h light (L):12 h dark (D)] and long-day (18L:6D) photoperiods for 10 days. This time period includes the s…
Photoperiodic regulation of life-history traits before and after eclosion: egg-to-adult development time, juvenile body weight and reproductive diapa…
2012
Photoperiod is the main environmental cue used by northern insects to predict the forthcoming seasonal changes and to adjust their life-history traits to fit these changes. We studied the effects of photoperiod on egg-to-adult development time, juvenile body mass and female reproductive diapause in two northern Drosophila montana populations with different patterns of voltinism. The most interesting findings were consistent between the populations: (1) when maintained before eclosion in short day conditions, representing early autumn, the flies developed faster and were lighter than when maintained in long day conditions, representing early summer, (2) photoperiodic time measurement is appa…
Northern Drosophila montana flies show variation both within and between cline populations in the critical day length evoking reproductive diapause
2013
Reproductive diapause, and its correct timing, plays an important role in the life cycle of many insect species living in a seasonally varying environment at high latitudes. In the present paper we have documented variation in the critical day length (CDL) for adult reproductive diapause and the steepness of photoperiodic response curves (PPRCs) in seven clinal populations of Drosophila montana in Finland between the latitudes 61 and 67°N, paying special attention to variation in these traits within and between cline populations. The isofemale lines representing these populations showed a sharp transition from 0% to 100% in females' diapause incidence in the shortening day lengths, indicate…
CONTINUO / DISCONTINUO. UNA QUESTIONE ITALIANA TRA PIANO E PROGETTO
2012
L’articolo introduce e commenta le questioni esposte nel contributo di Vito Corte sui piani particolareggiati per l’insediamento montano di Erice -vetta, prodotti da Bruno Gabrielli con lo stesso Vito Corte. L’approccio dei due piani al progetto del territorio [e del paesaggio] costituisce un contributo importante alla soluzione di questioni ormai cristallizzate nella dialettica tra piano e progetto. Se ne discutiamo con un occhio aperto soprattutto alla didattica del piano nelle facoltà italiane di architettura, e alla didattica del progetto di architettura nei corsi di laurea in pianificazione territoriale urbanistica e ambientale
Technical English for agriculture
2021
As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…
Odonats del País Valencià: diversitat, factors implicats en la composició de les seues comunitats i respostes als senyals de risc durant la fase d'ou
2017
Libèl·lules i espiadimonis són els noms comuns emprats per a anomenar eixos insectes que tan familiars en resulten i que configuren l’ordre escollit per a la realització d’aquesta tesi doctoral: el dels odonats. D’entre les característiques taxonòmiques que el configuren com a grup, cal destacar dos trets diagnòstics: un de la fase adulta i l’altre de la fase larvària. Un és l’òrgan copulador dels mascles adults, el qual s’ubica en el segon segment abdominal; aquesta característica determina un comportament reproductor exclusiu: durant l’aparellament el mascle doblega l’abdomen per a poder arribar a l’orifici genital de la femella. L’altre tret és la modificació del llavi inferior de les la…

Neurodidattica teatrale e la performance dell'apprendimento
2021
La Neurodidattica, o Neuroeducation, innestata nel campo della Neuropsicologia infantile, si colloca tra la Neurobiologia e le Scienze dell'educazione: la prima si basa sul principio per cui ogni apprendimento determina un cambiamento nel cervello, dato che le reti neurali subiscono alcune modifiche; le Scienze dell'educazione hanno come obiettivo quello di creare strategie e metodologie didattiche sempre più efficaci. L'incontro tra Neurodidattica e prassi teatrale genera un ripensamento di alcuni aspetti del processo di insegnamento apprendimento, quali la cognizione, l emozione, l espressività emotiva, i registri della comunicazione, con un esercizio significativo di quelle aree encefali…
Efecto de la dosis de intervención del Programa de Apoyo Psicológico P/Materno Infantil© sobre las madres y sus bebés
2014
This paper presents an analysis of the intervention dose-effect of the Parent Child Psychological Support Program© (Cerezo 1990) a program aimed at promoting protective adaptive system in children which is offered to all new-borns in a given catchment area. The program offers support to parents during the first 18 months of the baby's life. The program dose-effect is examined regarding the parents by examining the level of distress reported by them and with babies by examining the development of attachment using the Strange Situation test of Ainsworth et al. (1978). The study is based on 342 families who made between 2 and 4 visits to the Program before being evaluation post-intervention. T…
