Spina H, Norris D, Nong L, Dobney S, Mueller S, Freeman N, et al.
Horm Behav . 2025 Jan; 168:105679. PMID: 39884216
Given that double-brooding (rearing two broods within a season) can increase annual fecundity, it is unclear why some females in multi-brooded populations rear only one brood per season. The Quality...

Sutton A, Strickland D, Lachapelle J, Young R, Hanner R, Brunton D, et al.
PLoS One . 2024 Apr; 19(4):e0300583. PMID: 38656932
Accurately determining the diet of wild animals can be challenging if food items are small, visible only briefly, or rendered visually unidentifiable in the digestive system. In some food caching...

Fuirst M, Strickland D, Freeman N, Sutton A, Norris D
Proc Biol Sci . 2023 Apr; 290(1997):20221863. PMID: 37072037
While delaying natal dispersal can provide short-term benefits for juveniles, lifetime fitness consequences are rarely assessed. Furthermore, competition for limited positions on a natal territory could impose an indirect fitness...

Sorensen M, Strickland D, Freeman N, Fuirst M, Sutton A, Norris D
Biol Lett . 2022 Jan; 18(1):20210532. PMID: 35078329
For many species, breeding performance increases through early adulthood followed by declines later in life. Although patterns of age-specific decline have been shown to vary between individuals, the factors that...

Leishman E, van Staaveren N, Mohr J, Wood B, Freeman N, Newman A, et al.
Animals (Basel) . 2021 Jul; 11(7). PMID: 34202059
Phenological differences in energy demand (i.e., reproductive status) might influence the measurement of corticosterone. The objective of this study was to compare corticosterone concentrations in feathers (FCORT) and plasma (PCORT)...

Freeman N, Norris D, Sutton A, Strickland D, Kyser T, Newman A
Integr Comp Biol . 2021 Jun; 61(1):9-19. PMID: 34086914
Individuals undergo profound changes throughout their early life as they grow and transition between life-history stages. As a result, the conditions that individuals experience during development can have both immediate...

Sutton A, Strickland D, Freeman N, Norris D
Glob Chang Biol . 2020 Dec; PMID: 33347694
Understanding how events throughout the annual cycle are linked is important for predicting variation in individual fitness, but whether and how carry-over effects scale up to influence population dynamics is...

Leishman E, Freeman N, Newman A, van Staaveren N, Wood B, Harlander-Matauschek A, et al.
Poult Sci . 2020 Nov; 99(11):5261-5264. PMID: 33142441
The measurement of corticosterone in feathers is an appealing tool for assessing glucocorticoids in wild and domestic bird species. Feather corticosterone measurements can be performed noninvasively and can provide a...

Sutton A, Strickland D, Freeman N, Norris D
Ecology . 2020 Sep; 102(1):e03203. PMID: 32970843
Although density regulates the abundance of most wild animal populations by influencing vital rates, such as fecundity and survival, the mechanisms responsible for generating negative density dependence are unclear for...

Freeman N, Norris D, Sutton A, Newman A
Ecology . 2019 Oct; 101(1):e02909. PMID: 31605623
Food availability early in life can play a vital role in an individual's development and success, but experimental evidence for the direct effects of food on body condition, physiology, and...
