Status and Trends Program

Home

To protect, conserve, and restore the living resources—plants, animals, habitats, ecosystems—entrusted to their care, land and resource managers must understand the condition, or status (e.g., abundance, distribution, productivity, health), of those resources as well as their trends (i.e., how these variables change over time).

How do we know it's spring?

How do we know it

The First Leaf and First Bloom Indices are synthetic measures of these early season events in plants, based on recent temperature conditions. Get weekly updates about spring leaf out and blooms from the National Phenology Network!

American Recent Eulipotyphla: Nesophontids, Solenodons, Moles, and Shrews in the New World

The mammalian taxonomic order Eulipotyphla is comprised of the living taxonomic families Erinaceidae (gymnures, hedgehogs, and moonrats), Solenodontidae (solenodonts), Soricidae (shrews), and Talpidae (desmans and moles). Morphological and molecular studies continue to alter our view of relationships within and among these families, and this...

Multidirectional abundance shifts among North American birds and the relative influence of multifaceted climate factors

Shifts in species distributions are major fingerprint of climate change. Examining changes in species abundance structures at a continental scale enables robust evaluation of climate change influences, but few studies have conducted these evaluations due to limited data and methodological constraints. In this study, we estimate temporal changes in...

Molecular systematics of swifts of the genus Chaetura (Aves: Apodiformes: Apodidae)

Phylogenetic relationships among swifts of the morphologically conservative genus Chaetura were studied using mitochondrial and nuclear DNA sequences. Taxon sampling included all species and 21 of 30 taxa (species and subspecies) within Chaetura. Our results indicate that Chaetura is monophyletic and...
