Productivity of Black Oystercatchers in Southwest Alaska

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species. To address these issues, the goal of this research is to

 Standard Fish Sampling Techniques and Environmental DNA for Characterizing Fish Relative Abundance,
December 15, 2020

Standard Fish Sampling Techniques

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.

La encrucijada del fuego silvestre

La relación entre la gente y los incendios forestales siempre ha sido paradójica: el fuego es esencial como proceso ecológico y herramienta de gestión, pero también puede ser perjudicial para la vida y la propiedad.

Wildfire at the Crossroads

The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks. Reintroducing fire and its

I Am A...Chiropterologist (Halloween Edition)

As #BatWeek comes to an end, we figured it’s the perfect time to get a little bit more…animated. Over the last few weeks the USGS has been highlighting a handful of careers in our “I Am A..." web series. Since we are all batty at the moment, it seems like the perfect time to put the spotlight on chiropterologists, or bat scientists. One favor, though, please promise to not
