Questo nuovo libro nasce dal rispetto e dallamore profondo verso le piante e le "semplici" erbe officinali in particolare. Con spirito curioso ed affascinato, Saccavini cerca le leggende, le favole, le meraviglie, le virtu di queste piante, conosciute fin dal profondo passato e che sono oggi spesso confermate da prove scientifiche. Queste pagine vogliono essere un invito, un gentile richiamo, a ricordare i nostri rapporti stretti ed eterni con il mondo vegetale, proprio in questo tempo in cui ci troviamo di fronte ad atteggiamenti distruttivi o di fredda indifferenza verso le piante.

Leruzione del Krakatoa; lestinzione dei dinosauri e le altre grandi estinzioni di massa; la tragedia del Vajont; la Peste Nera. Sono solo alcune delle catastrofi che hanno segnato la violenta storia del nostro pianeta, mettendo in gioco forze inarrestabili, gigantesche, incommensurabili, e che talvolta hanno toccato da vicino la vita e le certezze umane.Cosa determina eventi tanto straordinari? Quali meccanismi ne sono allorigine? Alcuni disastri sono prevedibili?Breve storia delle catastrofi planetarie e un testo di ampio respiro, dove i temi trattati i disastri, di ordine sia naturale che artificiale si pongono come argomento di interesse in quanto tale, ma offrono loccasione per analizzare i processi naturali che animano e modellano il pianeta e le tecnologie coinvolte negli eventi, illustrando le deviazioni dalla norma che li hanno trasformati in agenti catastrofici. Gli eventi vengono illustrati, le cronologie sviscerate, la scienza esaminata da vicino. Descrivendo eventi straordinari della storia del pianeta, il volume offre una panoramica dettagliata dellintero arco di esistenza dello stesso. Chiude il volume unappendice che riassume le tappe piu violente della storia della Terra, dalla formazione del Sistema Solare alle grandi collisioni continentali ai terremoti storici.La presente edizione offre, rispetto alla precedente, un miglioramento della veste grafica, alcuni approfondimenti, la correzione di refusi marginali e unappendice cronologica piu estesa.Roberto Ciccariello (Gaeta, 1 ottobre 1988) e divulgatore e insegnante di Matematica e Scienze.

El búho es una contradicción. Es la más conocida y también la menos conocida de las aves. Pidamos a cualquiera que dibuje un búho y lo hará. Preguntémosle cuándo vio uno por última vez y dirá que no lo recuerda. Como ilustracion en un libro, si; como ave en un documental o en jaula de un zoologico, probablemente. Pero ¿cuando vio por ultima vez un buho vivo en la naturaleza? El buho es un timido predador nocturno de vuelo silencioso. A menos que salgamos de nuestro camino para avistarlo o hagamos incursiones nocturnas, no lo encontraremos facilmente. Sin embargo estamos muy familiarizados con su apariencia por la forma de su cabeza y su mirada, que parecen humanas. Esas cualidades humanas nos hacen atribuirle profundos pensamientos.Este libro nos cuenta como a lo largo de la historia los buhos han sido simbolo de sabiduria, de reflexion y tambien de maldad; incluso fueron tomados como vehiculo divino.En el siglo XXI, cuando por fin comenzamos a apreciar la fauna salvaje del planeta y a preocuparnos por su dramatica declinacion, tambien queremos conocer la fascinante biologia del buho.

The Burmese pythons, the subject of this care guide, is a giant snake with specific feeding, housing, and handling requirements, that is not ideal for most hobbyists and an unusual choice as a pet. Nonetheless, author Philippe de Vosjoli notes in the first chapter that his favorite snake was indeed a Burmese python, as no other snake "has ever equaled this particular animal in terms of personality and responsiveness." Indeed, he says, the Burmese pythons docile nature has done much to help dispel scary myths and misconceptions about snakes in general. For snake hobbyists interested in purchasing and keeping this gentle giant, Burmese Pythons is an excellent introduction to the selection and purchase of a healthy snake offering no-nonsense advice about handling, housing, feeding, and breeding these snakes. The authors chapter titled "How Accidents Happen" presents commonsense tips about handling Burmese pythons, discussing bites, the tail, and constriction, essential reading for all keepers, regardless of their experience level. Dr. Roger Klingenberg offers a chapter on diseases and disorders which proves useful and informative. A fully illustrated chapter dedicated to other large pythons offers information about size, longevity, morphs, maintenance, and breeding for the following giant snakes: the Indian python (a subspecies to the Asiatic rock python, like the Burmese python), the Sri Lankan python, the reticulated python, and the African rock python. Resources and index included.

ATTRACTIONS Succulent plants have been a feature of the horticultural scene for a long time, yet their appeal has not been dimmed by the passing years. When first brought into cultivation, their exotic appearance made them objects of great curiosity. Contemporary accounts reveal the sense of wonderment induced in the minds of those acquainted only with the familiar garden plants of the day. The first flowering of some of those early introductions was often deemed newsworthy but then, as now, the press reports were sometimes greatly distorted. Films and television have made the plants more familiar today. They are freely available from garden centres and chainstores, and one might assume that they would no longer retain their fascination. Yet one has only to watch the reaction of children at a flower show to realise that there is something elemental about the attractions of the plants. The children will pass magnificent displays of roses, chrysanthemums and the like with scarcely a glance, but very few will fail to linger in front of a display of succulent plants. What is it about these plants that appeals? It is usually cacti that make the initial impact. Their appearance is so different from that of other plants that attention is drawn to them. Instead of slender leafy stems, the majority of cacti have swollen stems with spines taking the place of leaves. The association of the plants with a struggle for life in a hostile environment enhances their appeal. The climax comes when the first flowering cactus is seen. Cactus flowers have a delicate beauty which contrasts with the stark appearance of the plants, and they are often brightly coloured. The range of forms among the cacti is considerable. Hollywood has made everyone familiar with the columnar organ pipe and flat-padded prickly pear types, but there are also cacti with globular bodies and many which offset to form mounds of clustering stems. In size they range from tiny plants with bodies less that in (1cm) in diameter to giants 40ft (12m) or more in height. In addition to the cacti, many other plants have evolved to survive in arid regions. Some have an appearance superficially similar to that of the cacti, with fleshy stems and an absence of leaves. Some are rosette plants with fleshy leaves, while others compromise by having stout moisture-retaining stems and deciduous non-fleshy leaves. The variety of forms among these is even greater than among the cacti. Add the fact that many of the leaves are of delicate pastel colours, or covered with a powdery farina, or clad with soft hairs just appealing to be stroked, and one can understand why people find it difficult to resist touching the plants. The exotic appearance of these plants might lead the uninitiated to think that they are difficult to cultivate. This is not the case: they are among the easiest of plants to grow. Apart from a small number, which are best avoided until experience has been gained by growing a variety of types, cacti and succulents are undemanding in their requirements. Given a porous compost, a position in good light, moderate watering and enough warmth to maintain a temperature just above freezing point, the majority can be expected not only to survive but to flourish and flower. It is possible to grow fine specimens on a windowsill, though a greenhouse makes life easier for the plants and their owner. Having evolved to cope with the rigours of a harsh natural environment, the plants are forgiving of neglect. A plant that can survive months of drought in the wild will not take exception to lack of watering while its owner is away on holiday.

Californian Flower Therapy is based on the same principles as Bach Flower Therapy with the difference that the essences used are those of flowers that grow spontaneously on the slopes of the Sierra Nevada, in California, in an area not yet directly contaminated by pollution.There are many more Californian remedies than Bachs (103 against Bachs 38 classic remedies), but the main difference lies in their extreme specificity and topicality; compared to Bach flowers, the Californian ones work on more modern and topical specific problems which at the time in which Bach lived were not as preponderant or were not yet talked about as today: anorexia and bulimia, sexual disorders, diseases resulting from environmental pollution. Usually, in fact, the flower remedies that have succeeded those of Bach have a more limited, targeted, therefore more symptomatic field of action. California flower essences were created in the late 1970s by a group of researchers led by Patricia Kaminski and Richard Kats, founders of the Flower Essence Society (FES), the distributor of these essences.The research that led to the identification of the remedies makes use of medical-holistic, psychological, botanical knowledge, in particular the plant is observed a lot, the environment in which it grows, and the way in which the plant relates to the environment, in this way it is possible to grasp the subtle nuances which will then help to clarify its use.

Neste livro me dediquei a falar mais sobre o dromedário que é da família dos camelos, também chamado de camelo árabe ou camelo de uma corcunda. O camelo de duas corcundas é comum na Ásia. Como estive em Dubai, Egito e em Israel onde reina absoluto os dromedarios e foi com esta especie que tive bastante contato em maio de 2023. Animal domesticavel, forte, resistente, util para transporte de pessoas e carga, fornece leite para alimentaço humana e tambem carne e pele para confecço de roupas ou tendas. Sem o auxilio destes animais seria muito mais dificil a vida humana nos desertos.
