Female alternative reproductive tactics: diversity and drivers
It is often argued that anisogamy causes alternative reproductive tactics (ARTs) to be more
common in males than females. We challenge this view by pointing out logical flaws in the …

Age-related changes in sperm traits and evidence for aging costs of sperm production in a sexually promiscuous passerine
In many animal species, organismal performance declines with age in a process known as
aging or senescence. Senescence typically leads to a deterioration of physiological …

Aging and Senescence across Reproductive Traits and Survival in Superb Fairy-Wrens (Malurus cyaneus)
Why do senescence rates of fitness-related traits often vary dramatically? By considering the
full aging trajectories of multiple traits, we can better understand how a species' life history …

Predictably philandering females prompt poor paternal provisioning
One predicted cost of female infidelity in socially monogamous species is that cuckolded
males should provide less parental care. This relationship is robust across species, but …

Experimental evidence that brighter males sire more extra‐pair young in tree swallows
LA Whittingham, PO Dunn - Molecular ecology, 2016 - Wiley Online Library
Across taxa, extra‐pair mating is widespread among socially monogamous species, but few
studies have identified male ornamental traits associated with extra‐pair mating success …

Extra-pair paternity patterns in European barn swallows Hirundo rustica are best explained by male and female age rather than male ornamentation
R Michálková, O Tomášek, M Adámková… - Behavioral Ecology and …, 2019 - Springer
Adaptive explanations for the evolution of extra-pair paternity (EPP) in birds often assume
cuckolding males to be better-ornamented than cuckolded males. Several studies have …

Extra‐pair paternity, breeding density, and synchrony in natural cavities versus nestboxes in two passerine birds
Most of what is known about extra‐pair paternity in hole‐nesting birds derives from studies
using artificial nesting sites, such as nestboxes. However, it has rarely been investigated …

Multiple paternity in a lek mating system: Females mate multiply when they choose inexperienced sires
Multiple mating by females is common and often driven by social constraints on female mate
choice. However, females mate with multiple males even in systems without these social …

Do the ages of parents or helpers affect offspring fitness in a cooperatively breeding bird?
Age-related changes in parental phenotypes or genotypes can impact offspring fitness, but
separating germline from nongermline transgenerational effects of ageing is difficult for wild …
