Modeling spatiotemporal abundance of mobile wildlife in highly variable environments using boosted GAMLSS hurdle models

Modeling organism distributions from survey data involves numerous statistical challenges, including accounting for zero‐inflation, …

Gradient boosting for distributional regression: faster tuning and improved variable selection via noncyclical updates

We present a new algorithm for boosting generalized additive models for location, scale and shape (GAMLSS) that allows to incorporate …

Where's the Grass? Disappearing submerged aquatic vegetation and declining water quality in Lake Mattamuskeet

Major threats to aquatic systems such as shallow lakes can include declining water quality, the loss of macrophyte beds, and the …

Bat activity during autumn relates to atmospheric conditions: implications for coastal wind energy development

The cryptic behavior of migrating bats leaves us largely uninformed of their seasonal distribution and abundance, important movement …

Two seconds is all it takes: European starlings (*Sturnus vulgaris*) increase levels of circulating glucorticoids after witnessing a brief raptor attack

Researchers typically study “acute” activation of the hypothalamic–pituitary–adrenal (HPA) axis by measuring levels of circulating …

Using land-based surveys to assess sea duck abundance and behavior in nearshore waters of southern New England, USA

Nearshore waters provide very important habitat for sea ducks (Tribe Mergini) during migration and winter, but gathering information on …

Using nocturnal flight calls to assess the fall migration of warblers and sparrows along a coastal ecological barrier

Atmospheric conditions fundamentally influence the timing, intensity, energetics, and geography of avian migration. While radar is …

Fruit removal rate depends on neighborhood fruit density, frugivore abundance, and spatial context

Fleshy-fruited plants depend fundamentally on interactions with frugivores for effective seed dispersal. Recent models of frugivory …

Birds select fruits with more anthocyanins during autumn migration

We evaluated whether fruit selection by autumn-migrating birds at an important stopover site in southern New England was related to …

A mass balance approach to identify and compare differential routing of 13^C^-labeled carbohydrates, lipids, and proteins in vivo

All animals route assimilated nutrients to their tissues where they are used to support growth or are oxidized for energy. These …

Deuterium measurements of raptor feathers: does a lack of reproducibility compromise geographic assignment?

Despite the widespread use of stable isotopes in studies of avian movement, key assumptions on which the methodology is based remain …

Intrafeather and intraindividual variation in the stable-hydrogen isotope (δD) content of raptor feathers

Stable-hydrogen isotope ratios (deuterium:protium; δD) in feathers enable researchers to evaluate patterns of avian movement and to …

Variation in the stable-hydrogen isotope composition of Northern Goshawk feathers: relevance to the study of migratory origins

The analysis of stable-hydrogen isotope ratios in feathers (δDf) allows researchers to investigate avian movements and distributions to …
