The post-fledging dependence period in the Lesser Kestrel Falcon naumanni [PDF]

, 1994
We studied the post-fledging dependence period of individually marked lesser kestrels (Falco naumanni) in southwestern Spain. Chicks fledged at a mean age of 37 d and remained at the breeding colony, depending on their parents for food, on ...

Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...

A Waterfowl Reproduction Model to Predict Carryover Effects of Oil Spills. [PDF]

Ecol Evol
For wintering and migrating birds, contamination from oil and other substances may delay arrival on the breeding grounds and lead to lower body mass upon arrival. These delays and losses of body mass could lead to smaller clutch sizes and lower propensity to renest.

Habitat use and characteristics of Connecticut Warbler during the nesting and post-fledging period

, 2023
Widespread declines in breeding bird populations have been documented across North America since the 1970s, and concerns about loss of avian biodiversity are growing.

A strategic method for expanding the Pacific Flyway Motus network

The Journal of Wildlife Management, EarlyView.
We identified high‐use areas of the Pacific Flyway by state where new Motus receiving stations would have the highest probability of detecting multiple tagged avian species of interest with the highest certainty. Abstract Understanding the movement and survival of birds of conservation concern during migration is critical for guiding conservation ...

Regulation of the Dependence Period in Booted Eagles: Effects of Nutritional Condition

Birds
The post-fledging dependence period is a crucial stage in the development of altricial birds that may influence their future performance and fitness. This period is regulated by parental investment, in terms of food provisioning and protection, and the ...

Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

Hatching and fledging? A meta‐analysis of the performance effects of business incubators

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Business incubators are among the most widely implemented instruments to foster entrepreneurship. Yet empirical evidence on their effectiveness remains fragmented and often contradictory. Limited research systematically compares how different types of incubators influence multiple venture performance outcomes, including ...
