      Dolphins hold hands and use 'names' for their friends, according to new study

        Virus lives in pig and doesn't kill the host. But kills the secondary host eg something that eats pigs wolf or dog bear..very convenient for defence pigs survival?
        When you look into it there are all kinds of diseases that could adapt to human and kill or harm us.

          Mammals turn to night life to avoid people

          Researchers analysed 76 published studies that monitored the activity of 62 mammal species, including some that are mostly nocturnal by nature, on 6 continents. They compared the night-time activity of each species during periods of time or in regions with high human disturbance, such as during hunting season or in areas rife with roads, with their night-time activity during periods of time or in regions with low human disturbance. The findings1, published on 14 June in Science, show that most mammals become on average 20% more active at night in response to higher levels of human disturbance.

          OP: The influence of human disturbance on wildlife nocturnality

          As the human population grows, there are fewer places for animals to live out their lives independently of our influence. Given our mostly diurnal tendencies, one domain that remains less affected by humans is the night. Gaynor et al. found that across the globe and across mammalian species—from deer to coyotes and from tigers to wild boar—animals are becoming more nocturnal (see the Perspective by Benítez-López). Human activities of all kinds, including nonlethal pastimes such as hiking, seem to drive animals to make use of hours when we are not around. Such changes may provide some relief, but they may also have ecosystem-level consequences.

          We are driving back the mammal fauna to what it used to be when the dinosaurs were threatening it : noctural activities
          Yes we are the new dinos....
          As disturbing, invasive and threatening that the dinos were

            How warming seas are forcing fish to seek new waters


            Scottish fishermen have uncovered an intriguing way to supplement their income: they have added squid to the menu of marine creatures they regularly pull from the sea. A species normally associated with the warmth of the Mediterranean, rather than the freezing north, may seem an odd addition to their usual catches of cod and haddock. Nevertheless, squid has become a nice little earner for fishing boats from Aberdeen and the Moray Firth in recent years. Thirty years ago, squid was a rarity in the North Sea. Today, boats bring back thousands of tonnes a year – though cod and haddock still dominate catches. Nor is this warm-water addition to northern fish menus a unique feature. Red mullet, sardines and sea bass have also appeared with increasing frequency in North Sea fishermen’s nets in recent years. All of them are associated with warmer waters and their appearance is seen by many scientists as a sign that climate change is beginning to have a serious impact on our planet’s oceans.
            For Scottish lovers of fresh squid, this is good news. However, in many other parts of the world, rising sea temperatures – triggered by climate change – are providing fishing industries and governments with major headaches. Fish are moving hundreds of miles from their old grounds, sometimes out of zones that had been set up to protect them. In other cases, fish are simply disappearing from nets.
            In short fish stocks are moving. There will be some winners (mainly up North) and losers (mainly in already warm waters). And as fish stocks are moving, fish wars can be expected again

              Orange crocodiles (and i am not talking about Trump )

              A new variety (or sub specie) of dwarf crocodile
              but orange and cave dwelling
              were found re"cently in Gabon
              They feed on bats, crickets and algaes
