Waterfowl poisoning halved by lead shot prohibition and more wildlife health news stories


Micropredators dictate occurrence of deadly amphibian disease

An international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredators may efficiently reduce the number of free-swimming infectious stages (zoospores) by consuming them.

This natural behavior will reduce the infection pressure on potential amphibian hosts and a goes a long way towards explaining the occurrence of chytridiomycosis, at least in temporal climatic regions. These results were published in the renowned scientific journal Current Biology. The team of researchers state that their results raise the hope of successfully fighting chytridiomycosis, nowadays one of the most deadly wildlife diseases.

Waterfowl poisoning halved by lead shot prohibition

Lead shot was forbidden in 2001 in Spanish wetlands on the Ramsar List of these areas of international importance. Ten years later, this prohibition -and the consequent use of steel shot by hunters- has started to bear fruit, according to a report in the journal 'Environment International'.

"The most important part of our work is that it shows that, despite it's still covering a partial area, the change of material from lead to steel shot has reduced waterfowl poisoning and the contamination of hunted meat," Rafael Mateo Soria of the Hunting Resources Research Institute (IREC) and co-author of the study, told SINC.
