Pollinators

Pollinators are crucial contributors to our environment and society by enhancing plant diversity in wild lands and providing food for humans in agricultural settings. Some three-fourths of all native plants in the world require pollination by an animal, most often an insect, and most often a native bee.

Experimental suppression of invasive lake trout: Implications for conservation of imperiled bull trout in Glacier National Park

After 14,000 years of dominance, Glacier National Park’s (GNP) greatest native aquatic predator is at high risk of extirpation (local extinction) in several lakes on the western slopes of the Continental Divide. The decline of threatened bull trout in GNP is directly attributed to the invasion and establishment of nonnative lake trout, which consistently displace bull trout in systems where...

Relationship of Bat Fatality to Activity in the Rotor-Swept Zone

We are conducting daily fatality searches for bat carcasses in order to relate fatality pattern to measures of bat activity, as well as to daily environmental conditions - such as weather, moon phase, and day of year.

Estimating the Abundance of an Animal Population When the Total Observed Count is Zero

We are developing the theoretical statistical framework that would allow inference from known search effort and detectability parameters regarding estimated fatality when there are no or few observed carcasses. In addition, we are developing software that resource managers as well as developers can use to design fatality monitoring protocols optimized for different objectives.

A General Estimator of Wildlife Fatality from Count Data

We are creating an estimator that allows a more general parameterization of carcass arrival and persistence times, while accommodating the different assumptions regarding the likelihood that a carcass is observed.

Fatality Estimation Software

We are developing publicly available open-source software that uses data provided by the user to estimate the probability that a searcher will miss a carcass and the probability that a carcass will be removed before a searcher has the opportunity to observe it. The estimates are combined with the observed casualties and an estimate of the fraction of the population of killed animals expected...

First Days - Harlequin Ducks

This ridiculously cute video of baby Harlequin Ducks (Histrionicus histrionicus) shows their first day outside the egg (about 20 hours old). Scientists at Patuxent Wildlife Research Center are training ducks to respond to sounds — just like a hearing test given to kids during elementary school — to learn more about their ability to hear underwater. This will inform the design of effective...

Not Just for Kissing: Mistletoe and Birds, Bees, and Other Beasts

Perhaps some of you have already experienced a sweet smooch or two under the holiday mistletoe, enjoying this fairly old kissing ritual for people. While figuring prominently in ancient lore, mistletoe is important in other vital ways: it provides essential food, cover and nesting sites for an amazing number of critters. In fact, some animals couldn’t even survive without mistletoe.
