THE ONTOGENY OF POSTCRANIAL INTEGRATION IN THE COMMON TERN,STERNA HIRUNDO [PDF]
Evolution, 1993 Empirical and theoretical work supports the concept that developmentally or functionally related characters tend to covary and hence evolve together. However, the dynamics of the developmental processes that establish within population covariance structures are not well understood.

The comparative breeding ecology of sympatric common and arctic terns in N.E. England [PDF]
, 1999 The life-history traits of two sympatric seabird species, the Common Sterna hirundo and Arctic Tern S. paradisaea, and the flexibility of these traits in relation to short and longer term changes in environmental conditions were measured at Coquet Island,

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Breeding performance of Common Terns (Sterna hirundo) does not decline among older age classes
The AUK: A Quarterly Journal of Ornithology, 2020 Declines in reproductive performance among older age classes have been reported in many bird and mammal species, and are commonly presented as demonstrating reproductive senescence.

Responses of Antarctic seabird populations to past climate change
Ecography, Volume 2026, Issue 10, October 2026.Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...
