Flawed method puts tiger rise in doubt, calls for new approach
Flaws in a method commonly used in censuses of tigers and other rare wildlife put the accuracy of such surveys in doubt, a new study suggests.
New method to assess hormone metabolite concentrations in wildlife research
Measuring hormone metabolites in urine and faeces are essential for studies in wildlife conservation. Scientists from the German Leibniz Institute for Zoo and Wildlife Research (IZW) developed a new method ...
Laser scanning accurately 'weighs' trees
A terrestrial laser scanning technique that allows the structure of vegetation to be 3D-mapped to the millimetre is more accurate in determining the biomass of trees and carbon stocks in forests than current ...
New technique may help assess how plastic pollution impacts wildlife
By swabbing oil from a gland located at the end of a seabird's tail and analyzing the sample with gas chromatography-mass spectrometry, researchers have developed a way to measure wildlife's exposure to plastics.
Study reveals that particle size matters for environmental DNA monitoring
(Phys.org) —University of Notre Dame scientists have now published the first detailed investigation of just how small (or big) environmental DNA, or eDNA, particles really are, and their results provide ...
UV-radiation data to help ecological research
Many research projects study the effects of temperature and precipitation on the global distribution of plant and animal species. However, an important component of climate research, the UV-B radiation, is ...
Friendly information signs reduce vandalism on scientific equipment
Behavioural biologists conducting research in the field often depend on state-of-the-art techniques. Consequently, damage to or theft of technical equipment represents a dramatic financial and scientific ...
Tagging aquatic animals can disrupt natural behavior
American and Canadian researchers have for the first time quantified the energy cost to aquatic animals when they carry satellite tags, video cameras and other research instruments.
Scientists develop new method of estimating fish movements underwater
How do you track a fish? There's no "Google Maps" for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists ...
Marine diversity study proves value of citizen science
Citizen science surveys compare well with traditional scientific methods when it comes to monitoring species biodiversity – according to new research from the University of East Anglia.
Computerised 'mug-shots' provide a 'who's who?' of seals
(Phys.org)—A new computerised photo-ID system is helping scientists monitor and track the grey seal population in the UK and beyond.
Scientists develop novel method to study parasite numbers in wild seabirds
Scientists have developed a new method for studying parasite numbers in the stomachs of individual seabirds in the wild. The technique enables the recording of video footage of worms inside seabird stomachs ...
Preserved frogs hold clues to deadly pathogen
A Yale graduate student has developed a novel means for charting the history of a pathogen deadly to amphibians worldwide.
