Untangling Colour Diversity: Ecogeographic Patterns in Two Scolopendra Species Revealed by Citizen Science

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using citizen‐science records, we analysed ecogeographic patterns of colour polymorphism in two closely related centipede species across Japan. While two colour morphs in Scolopendra mutilans are broadly sympatric, they are geographically restricted in S. japonica despite overlapping climatic niches and biotic interactions.

Brood parasitism by shiny cowbirds

open access: yes, 2016
Brood parasitic birds lay eggs amongst the clutches of other species, which then assume all costs of parental care on their behalf. This thesis addresses several puzzles of avian brood parasitism, using field studies and theoretical modelling of the ...

Behavioural and physiological responses to brood parasitism and nest predation in two passerine species [PDF]

open access: yes, 2017
Brood parasitism and nest predation are two of the most important selective pressures in birds, particularly in altricial species, which are the species whose nestlings, being born unfeathered, blind and helpless, must be cared by parents.

SUPPORTING INFORMATION from Nest architecture influences host use by avian brood parasites and is shaped by coevolutionary dynamics

open access: yes, 2023
Brood (social) parasites and their hosts exhibit a wide range of adaptations and counter-adaptations as part of their ongoing coevolutionary arms races. Obligate avian brood parasites are expected to use potential host species with more easily accessible

Nest design as an adaptative tool to escape brood parasitism

open access: yes, 2023
1. Nest characteristics vary depending on environmental factors but may also be influenced by between-species interactions. As a defence against avian brood parasites, hosts can evolve specific nest architecture to minimise risks of brood parasitism by ...

Reproductive success and male traits in the spotless starling, Sturnus unicolor [PDF]

open access: yes, 2009
Selection operates when the variability among individuals in heritable traits translates to differences in the number of offspring that survive to breed, which is a close estimate of fitness. Consequently, the outcome of sexual-selection should be higher

Avian Brood Parasitism: Variation in Host Repsonse

open access: yes, 2016
Obligate brood parasites forego the cost of parental care by laying their eggs in the nest of other species, often to the detriment of that species. About 1% of all bird species are obligate brood parasites, but the most well-known and commonly studied ...

Conspecific brood parasitism: reevaluating a bird’s-eye view [PDF]

open access: yes, 2022
Conspecific brood parasitism, also known as intraspecific brood parasitism, is characterized by individuals depositing eggs into the established nests of others of the same species.

Interspecific egg rejection as ecological collateral damage from selection driven by conspecific brood parasitism [PDF]

open access: yes, 2015
Distinguishing between interspecific and intraspecific coevolution as the selective driver of traits can be difficult in some taxa. A previous study of an avian obligate brood parasite, the black-headed duck, Heteronetta atricapilla, suggested that egg ...
