Effect of Feathers as Nest Insulation on Incubation Behavior and Reproductive Performance of Tree Swallows (\u3cem\u3eTachycineta bicolor\u3c/em\u3e)

, 1995
Many species of birds line their nests with feathers, presumably because of the insulative qualities of feathers and because feathers may act as a barrier between nest parasites and nestlings.

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.

Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

Oikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

Assessing the Impact of Trap Nests on Megachile Bee Population in Mung Bean

Journal of Scientific Research and Reports
This study explores the impact of nest installation on Megachile bee populations, which are potential pollinators of mung bean crops in Uttarakhand, India. Field investigations over two seasons reveal that six Megachile species visit mung bean blooms regularly for their provisioning.

The Fourier binest algebra. [PDF]

, 1997
The Fourier binest algebra is defined as the intersection of the Volterra nest algebra on L2([open face R]) with its conjugate by the Fourier transform. Despite the absence of nonzero finite rank operators this algebra is equal to the closure in the weak

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Diversity and abundance of bees in Passiflora edulis Sims (Passifloraceae) orchard, associated with Solanum lycocarpum St. Hill. (Solanaceae)

Acta Scientiarum. Agronomy
Brazil is the third-largest producer of fruits in the world, with yellow passion fruit (Passiflora edulis) as one of its main crops. This species requires cross-pollination, with Xylocopa bees being the primary pollinators due to its self ...

Multi‐year partner fidelity is associated with higher annual reproductive output in a biparental subtropical shorebird

Oikos, EarlyView.
Partner fidelity is a key component of reproductive strategies in socially monogamous species, yet its adaptive value remains context dependent and poorly understood outside environments with short breeding seasons. In most bird species, partners may remain together or re‐pair between successive nesting attempts, but it remains unclear which components

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, EarlyView.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.
