Ortega A, Merkle J, Sawyer H, Monteith K, Lionberger P, Valdez M, et al.
Ecology . 2024 Jan; 105(4):e4238. PMID: 38212148
Growing evidence supports the hypothesis that temperate herbivores surf the green wave of emerging plants during spring migration. Despite the importance of autumn migration, few studies have conceptualized resource tracking...

Xu W, Gigliotti L, Royaute R, Sawyer H, Middleton A
J Anim Ecol . 2023 Jan; 92(3):677-689. PMID: 36598334
Fences have recently been recognized as one of the most prominent linear infrastructures on earth. As animals traverse fenced landscapes, they adjust movement behaviours to optimize resource access while minimizing...

Broekman M, Hilbers J, Huijbregts M, Mueller T, Ali A, Andren H, et al.
Glob Ecol Biogeogr . 2022 Oct; 31(8):1526-1541. PMID: 36247232
Aim: Macroecological studies that require habitat suitability data for many species often derive this information from expert opinion. However, expert-based information is inherently subjective and thus prone to errors. The...
5.
Aikens E, Wyckoff T, Sawyer H, Kauffman M
Nat Ecol Evol . 2022 Oct; 6(11):1733-1741. PMID: 36202922
The ability to freely move across the landscape to track the emergence of nutritious spring green-up (termed 'green-wave surfing') is key to the foraging strategy of migratory ungulates. Across the...

Sandoval Lambert M, Sawyer H, Merkle J
Ecol Appl . 2022 May; 32(7):e2652. PMID: 35543078
While migrating, animals make directionally persistent movements and may only respond to human-induced rapid environmental change (HIREC), such as climate and land-use change, once a threshold of HIREC is surpassed....
7.
Esmaeili S, Jesmer B, Albeke S, Aikens E, Schoenecker K, King S, et al.
Ecol Lett . 2021 Jul; 24(10):2178-2191. PMID: 34311513
The forage maturation hypothesis (FMH) states that energy intake for ungulates is maximised when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource...

Kauffman M, Cagnacci F, Chamaille-Jammes S, Hebblewhite M, Hopcraft J, Merkle J, et al.
Science . 2021 May; 372(6542):566-569. PMID: 33958460

Xu W, Barker K, Shawler A, Van Scoyoc A, Smith J, Mueller T, et al.
Ecology . 2021 Feb; 102(4):e03293. PMID: 33554353
Migratory ungulates are thought to be declining globally because their dependence on large landscapes renders them highly vulnerable to environmental change. Yet recent studies reveal that many ungulate species can...

Morrison T, Merkle J, Hopcraft J, Aikens E, Beck J, Boone R, et al.
J Anim Ecol . 2021 Jan; 90(4):955-966. PMID: 33481254
While the tendency to return to previously visited locations-termed 'site fidelity'-is common in animals, the cause of this behaviour is not well understood. One hypothesis is that site fidelity is...
