Birch G, Nichols H, Mwanguhya F, Blount J, Cant M
R Soc Open Sci
. 2025 Feb;
12(2):242215.
PMID: 40012759
Alternative reproductive tactics (ARTs) allow less competitive individuals to reproduce by avoiding direct fights through sneaky strategies. Within cooperatively breeding groups ARTs are rarely reported, potentially owing to observational difficulties...

Khera M, Arbuckle K, Mwanguhya F, Cant M, Nichols H
Behav Ecol
. 2025 Feb;
36(2):araf007.
PMID: 39980874
Reproduction is an energetically costly activity and so is often timed to occur when conditions are most favorable. However, human-induced changes in long-term, seasonal, and short-term climatic conditions have imposed...

Birch G, Cant M, Nichols H, Meniri M, Businge R, Mwanguhya F, et al.
Sci Rep
. 2025 Jan;
15(1):1434.
PMID: 39789011
Promiscuous females reduce male reproductive control. Males can attempt to monopolise access to these females, but distractions and sneaky rivals mean extra copulations cannot always be blocked. By mating first,...

Arbon J, Morris-Drake A, Kern J, Howell G, Wentzel J, Radford A, et al.
R Soc Open Sci
. 2024 Oct;
11(10):241125.
PMID: 39359473
Cooperatively breeding societies show distinct interspecific variations in social and genetic organization. Long-term studies provide invaluable data to further our understanding of the evolution and maintenance of cooperative breeding but...

Birch G, Meniri M, Mitchell C, Mwanguhya F, Businge R, Ahabyona S, et al.
Antioxidants (Basel)
. 2024 Sep;
13(9).
PMID: 39334783
Reproductive activity is costly in terms of future reproduction and survival. Oxidative stress has been identified as a likely mechanism underlying this cost of reproduction. However, empirical studies have yielded...

Birch G, Nichols H, Mwanguhya F, Thompson F, Cant M, Blount J
Proc Biol Sci
. 2024 Sep;
291(2031):20241499.
PMID: 39288806
The costs of reproductive conflict can shape the evolution of life-histories in animal societies. These costs may change as individuals age and grow, and with within-group competition. Social costs of...

Khera M, Arbuckle K, Mwanguhya F, Kyabulima S, Mwesige K, Businge R, et al.
Biol Lett
. 2023 Nov;
19(11):20230328.
PMID: 37990567
Human-induced climate change is leading to temperature rises, along with increases in the frequency and intensity of heatwaves. Many animals respond to high temperatures through behavioural thermoregulation, for example by...

McCormack J, Arbuckle K, Fullard K, Amos W, Nichols H
Behav Ecol
. 2023 Nov;
34(6):950-959.
PMID: 37969551
Life-history theory suggests that individuals should reproduce until death, yet females of a small number of mammals live for a significant period after ceasing reproduction, a phenomenon known as post-reproductive...

Ellis S, Johnstone R, Cant M, Franks D, Weiss M, Alberts S, et al.
Nat Ecol Evol
. 2022 Sep;
6(11):1766-1776.
PMID: 36163259
The ultimate payoff of behaviours depends not only on their direct impact on an individual, but also on the impact on their relatives. Local relatedness-the average relatedness of an individual...

Meniri M, Evans E, Thompson F, Marshall H, Nichols H, Lewis G, et al.
Ecol Evol
. 2022 Mar;
12(3):e8644.
PMID: 35342583
The cost of reproduction plays a central role in evolutionary theory, but the identity of the underlying mechanisms remains a puzzle. Oxidative stress has been hypothesized to be a proximate...
