A Scalable Hydrology-Informed Monitoring System for Early Detection of Slope Failures Using IoT and ML

open access: yesIEEE Access
Landslides pose significant risks to infrastructure, the environment, and human life, particularly when triggered by intense or prolonged rainfall. Accurate and timely prediction of slope failures remains challenging due to the complex interactions ...

The performance of drones and artificial intelligence for monitoring sage‐grouse at leks

open access: yesWildlife Biology, EarlyView.
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

A new species and new records of Aphodius Illiger (Coleoptera: Scarabaeidae: Aphodiinae) from mammal burrows in Nebraska [PDF]

open access: yes, 2006
Direct sampling of rodent burrows in Nebraska resulted in the collection of 16 species of Aphodius Illiger previously unknown from the state, including specimens of four undescribed species.

Experimental lure design reveals the best attractants for increasing detection of multiple mesocarnivores

open access: yesWildlife Biology, EarlyView.
Many mesocarnivores have low detection rates that hinder practitioners' abilities to implement effective monitoring strategies. Using olfactory attractants (i.e. lures) may increase detection rates, but variation in effects among species is not well understood.

Analysis of soil and species composition [PDF]

open access: yes
Measurements were made during May to October, 1987 and June to August, 1989 over a tallgrass prairie near Manhattan, Kansas. Soil at the experimental site is predominantly Dwight silty clay loam.

Demographic viability of populations of \u3cem\u3eSilene regis\u3c/em\u3e in midwestern prairies: relationships with fire management, genetic variation, geographic location, population size and isolation [PDF]

open access: yes, 1998
We studied the demographic viability of populations of a long-lived iteroparous prairie perennial, Silene regia, in relation to management regimes, population sizes, geographical region (Ohio and Indiana vs.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

open access: yesWildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Energized fencing reduces risk of American black bear (Ursus americanus) damage to bird feeders in Minnesota

open access: yesWildlife Society Bulletin, EarlyView.
Energized fences were effective at reducing black bear damage to bird feeders. The fences were 100% effective in a good natural bear food year and 77% effective in a poor natural bear food year. When bears breached the fences, the cause was typically poor electrical grounding.

Design considerations for breeding waterfowl surveys

open access: yesWildlife Society Bulletin, EarlyView.
This study evaluated how different survey designs affect the accuracy and precision of breeding waterfowl population estimates in Iowa's Prairie Pothole Region. Using aerial survey data from 2016–2018, we found that conducting at least 2 visits per season reduced bias in pair estimates, particularly for wood ducks and blue‐winged teal, while mallard ...
