How Wolves Change Rivers

I came across the video below on the Wolf Conservation Centre web site.  The video shows an excellent example of the interconnectedness of nature.

Below is an excellent short video about the impact of predators on ecosystems.  The Mongabay news item Wolves Boost Food for Yellowstone’s Threatened Grizzlies is also worth reading, as is Yale Environment 360’s analysis The Crucial Role of Predators: A New Perspective on Ecology.

Iran’s Grey Wolf – Prey Selection

The grey wolf has the largest geographical range of large mammalian carnivores in west Asia, however, it is one of the least studied species.

A study which investigated the diet of the grey wolf in Ghamishlou found that livestock was the most important prey species with 47.1% of total biomass consumed, whereas Persian gazelle comprised 27.0% and wild sheep 15.9%.

Based on interview surveys, less than 1% of mean herd size was lost to wolf depredation, however, almost six times more died from non-depredation causes during each winter.

The study concluded the high occurrence of livestock in the wolves’ diet is mainly because of scavenging rather than depredation.
