Article Synopsis
- Population density is crucial for wildlife management, particularly in the Russian Far East, where methods like the FMP snow tracking are used to estimate ungulate densities and support Amur tiger conservation.
- Despite the effectiveness of FMP, reliability issues due to climate change and survey design challenges prompt the exploration of camera traps as an alternative for monitoring prey density, though their potential is still largely untested.
- A comparative study over three years found that, while both FMP and camera trap methods provided similar prey density estimates, discrepancies in prey biomass calculations highlight the need for caution in management decisions and suggest more research is necessary to improve estimation methods.
Objectives: This study aimed to evaluate the performance of a low-cost smoke sampling platform relative to environmental and occupational exposure monitoring methods in a rural agricultural region in central Washington state.
Methods: We co-located the Thingy AQ sampling platform alongside cyclone-based gravimetric samplers, a nephelometer, and an environmental beta attenuation mass (E-BAM) monitor during August and September of 2020. Ambient particulate matter concentrations were collected during a smoke and non-smoke period and measurements were compared across sampling methods.
Accurate identification of cyanobacteria using traditional morphological taxonomy is challenging due to the magnitude of phenotypic plasticity among natural algal assemblages. In this study, molecular approach was utilized to facilitate the accurate identification of cyanobacteria in the Sacramento-San Joaquin Delta and in Clear Lake in Northern California where recurring blooms have been observed over the past decades. Algal samples were collected from both water bodies in 2011 and the samples containing diverse cyanobacteria as identified by morphological taxonomy were chosen for the molecular analysis.
