Over two thirds of the earth's surface is covered by water, and adaptation to the aquatic habitats dominated the first 150 to 200 million years of vertebrate development. More than half the living ...vertebrates are aquatic. Fish have evolved to colonise almost every type of aquatic habitat, and today they are a hugely diverse group of about 25,000 species. Evolution of this great diversity has resulted in fascinatingly different designs for special modes of life as well as solutions to the problems common to them all. Comparisons help to reveal the biological and physiological compromises fish have to make to satisfy the often conflicting demands on their lives. Today fish are found in almost every imaginable watery habitat, which include the shallows and depths of the oceans, coastal waters and estuaries, rivers, streams, lakes, ponds, and ephemeral water bodies. Many species inhabit freezing waters in polar regions whilst others thrive in ponds fed by thermal springs. Some have abandoned the water and become air breathers. Tunas in the open oceans swim rapidly and outperform their prey. How do they generate the forces required for high-speed swimming? Study of these fish shows that they have large masses of warmed red muscle, and that the required amounts of oxygen are delivered by unusually efficient respiratory and circulatory systems. Some freshwater carp are able to survive the long periods of very low oxygen levels that periodically occur in some ponds and lakes. How is their metabolism switched from aerobic to anaerobic pathways? The challenges of living in a particular environment are in part met by adaptations of body form and physiological function. Yet there are wider and equally important questions, such as why are these species successful in their particular environments? Answers to such questions may be found in the study of behaviour, in the dynamics of populations, in the ecology of the species and in evolutionary theory.
Ob raziskovanju sledov rimskodobne poselitve na Grubljah (Vipava) so bili izkopani 403 ostanki velikih sesalcev, od tega 108 taksonomsko določljivih. Skupno je bilo med njimi zastopanih ...najmanj pet vrst (tj. domače govedo z dobrima dvema tretjinama najdb, ovca in/ali koza, domači prašič, konj in jelen), morda pa tudi tur in zober. Biometrična analiza govejih kosti je pokazala na prisotnost ostankov velikih živali napredne “rimske” pasme tudi še v četrtem stoletju, tj. ob nastopu poznoan-tičnega obdobja. Prav tako je s podatki za rimskodobne primerke iz širše regije skladna plečna višina konja, kateremu je pripadala edina nepoškodovana dolga kost v celotnem gradivu (tj. stopalnica). Govedoreja, sicer osrednji vir mesa za lokalno prebivalstvo, je bila primarno domnevno usmerjena v izkoriščanje volov (in krav?) kot delovne živine. Največ 6,6-odstotni delež ostankov lovnih vrst priča o (količinsko) skromnem pomenu divjačine v lokalni prehrani.

Šmartno pri Litiji: v Šmartno pri Litiji je pred časom priletel par štorkelj in si na drogu električne napeljave začel urejati gnezdo. A ljudje so hitro opazili, da gnezdo na ozkem drogu ne bo preživelo niti močnejše sape, zato so delavci Elektra zavihali rokave in štorkljam priskočili na pomoč.- Šmartno pri Litiji: Some time ago, a pair of storks flew into Šmartno pri Litiji and started building their nest on the top of an electric pole. People quickly realised that the nest on a narrow pole won't survive any strong gusts of wind. A team of workers from the Elektro Company decided to assist the storks.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.

Dolenjska: obrežje Krke so zasedli bobri. Prvega so na Dolenjskem opazili leta 1998, zdaj jih je že toliko, da ob reki zmanjkuje vrb s katerimi se najraje hranijo. Zato se lotili še dolenjskih hrastov, kar lahko povzroči kopico težav.- Dolenjska: Beavers occupied the banks of the Krka river. The first one was spotted in the region in 1998, but they have multiplied so much that the willows, their favourite food, are disappearing from the banks. This caused beavers to start chewing on oaks which can cause numerous problems.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.

Piran: slovensko morje že nekaj dni gosti nevsakdanjega obiskovalca - kita grbavca. Najprej so ga opazili pri Trstu, zadnje dni pa kroži med Piranom in Strunjanom. Ker ta vrsta kitov sicer ne živi pri nas, strokovnjaki domnevajo, da se je ali izgubil, ali pa se je prišel sem hranit.- Piran: For several days, the Slovene sea is host to a very unusual visitor – a humpback whale. It was first spotted offshore Trieste, but now circles between the towns of Piran and Strunjan. Since the species does not live in our sea, experts assume the animal is lost or has come here in order to feed.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
