Excitatory and inhibitory synapse reorganization immediately after critical sensory experience in a vocal learner

eLife, 2018
Excitatory and inhibitory synapses are the brain’s most abundant synapse types. However, little is known about their formation during critical periods of motor skill learning, when sensory experience defines a motor target that animals strive to imitate.

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Animal Logic: Locke and the Nature of Inference

Noûs, EarlyView.
ABSTRACT Can animals reason? If so, what would their reasoning consist in, and how, if at all, would it differ from its human counterpart? On these questions, John Locke stakes out a position that also merits consideration today. I argue that, for Locke, reasoning is a matter of the subject's construing her mental states as support for a conclusion ...

Exotic plants and other habitat characteristics do not impact Veery reproductive success at multiple spatial scales in northeastern Pennsylvania

Avian Conservation and Ecology
It is expected that birds have evolved nest site preferences that, on average, lead to positive fitness outcomes. It is possible, however, that mismatches occur between these preferences and reproductive success when a population experiences sudden ...

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

Plant Biotechnology Journal, EarlyView.
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Cross-scale habitat selection reveals within-stand structural requirements for fledgling Golden-winged Warblers

Avian Conservation and Ecology, 2021
The post-fledging period remains one of the most understudied portions of the avian lifecycle despite the fact that fledglings require resources distinct from those used during nesting.

Oculomotor learning revisited: a model of reinforcement learning in the basal ganglia incorporating an efference copy of motor actions

Frontiers in Neural Circuits, 2012
In its simplest formulation, reinforcement learning is based on the idea that if an action taken in a particular context is followed by a favorable outcome, then, in the same context, the tendency to produce that action should be strengthened, or ...

Planted grasslands have equivalent or higher arthropod biomass than native grassland important to nesting Sprague's Pipits (Anthus spragueii) early in the breeding season

Restoration Ecology, EarlyView.
Abstract Introduction Grassland species are declining globally. Sprague's Pipit (Anthus spragueii), a native grassland‐obligate, nests in planted grasslands in some regions. How food resources in planted grassland compare with those in native grassland is important to determine the relative benefits of creating new grassland by seeding cropland with ...

Assessing working lands as habitat for disturbance‐dependent birds using autonomous recording units

Restoration Ecology, EarlyView.
Abstract Introduction Working lands can provide habitat for declining disturbance‐dependent birds, such as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus), but it remains unclear whether restoration following intensive land use (e.g. surface mining) yields habitat comparable to less intensive land uses (e.g.

The alarmingly threatened Aquatic warbler: from early ecological insights to current conservation priorities

Restoration Ecology, EarlyView.
The Aquatic warbler (Acrocephalus paludicola) is the rarest songbird of continental Europe and a fen mire specialist. The systematic drainage in the eighteenth and nineteenth centuries resulted in the loss of almost all fen mires in the breeding range. In our conservative and cautious estimate, we assume that the total historical population was around ...
