Parlando dell'inverno (anche se ufficialmente siamo ancora in autunno!!) mi viene in mente quello del 2008-2009 qui sull'Appennino tosco emiliano.
A parte il freddo e la neve, fattori naturali e normali a certe altitudini, é stata la carenza di frutti del bosco (ghiande e castagne) a fare our friends suffer some ungulates.
remember that many animals have come closer to roads and houses to feed on hedges (much like those of Prunus laurocerasus and Viburnum tinus) and "peel" the trunks of fruit trees are not properly protected.
signs of hunger in the woods were clearly visible on the young chestnut trees and ivy, completely devoid of leaves up to "high Cervo.
Alps the situation is really dramatic with the discovery of so many dead deer.
That winter has been much debate whether or not interventions were just feeding the animals.
I do not want to go into the discussione ma, se da una parte l'inverno è l'unico "selettore naturale" (se escludiamo i pochi predatori naturali) di questi animali, dall'altra bisogna considerare che i Cervi e i Caprioli sono specie meno adatte alle dure condizioni dell'inverno alpino rispetto a bovidi come lo Stambecco o il Camoscio.
Il grosso problema non è tanto la temperatura rigida di questa stagione ma la quantità di neve caduta e la sua permanenza al suolo che impedisce la deambulazione e dunque la possibilità di cercare cibo.
Un istituto di ricerche faunistiche ed ecologiche di Vienna ha svolto recentemente studi sulla biologia del cervo; ad alcuni soggetti sono stati applicati apparecchi che, using telemetry techniques, transmitting data on heart rate and subcutaneous temperature.
has discovered that during the winter, the nights cooler and in a few hours of the day, to save energy can lower both the Deer and enter these parameters in real lethargic hibernation phase lasting 8-9 hours ( W. Arnold, Der verborgene Winterschlaf des Rothirsches , in "Wildbiologie Physiologie", 9, 3, 2003).
Some pictures of winter 2008-2009:

A BOOK that I recommend!
I recently read "With the eyes of a fawn" Elizabeth Marshall Thomas (Longanesi Publisher, € 18.60).
We are in rural New Hampshire, where the oak trees in the fall of 2007 decided to discontinue the usual production of acorns, jeopardizing much of the wildlife of the region.
A terrible episode in its simplicity, which gave to Elizabeth Marshall Thomas, the world-famous naturalist, the inspiration for a much broader search.
Trying to overcome the announced killing of starvation, it decided to distribute some corn fields next to his house more than thirty white-tailed deer (Odocoileus virginianus ) came to eat, a larger sample enough for a careful naturalist like her.
One of the chapters is titled "The risks of giving food to the animals "....
I highly recommend it! Let me know!!
