Avian species host diverse communities of microorganisms which have important roles in the life of birds, including increased metabolism, protection from disease, and immune system development. Along with high human populations and a diversity of human uses of coastal zones, anthropogenic food sources are becoming increasingly available to some species, including gulls. Anthropogenic associations increase the likelihood of encountering foreign or pathogenic bacteria. Diseases in birds caused by ...

Farallonophilus cavernicolus (Rentz, 1972) is a member of the family Rhaphidophoridae (camel crickets) endemic to the Farallon Islands. Rentz (1972) hypothesized that F. cavernicolus had characteristics between those of the genera Pristoceuthophilus Rehn, 1903 and Ceuthophilus Scudder, 1862 but closest to the genus Pristoceuthophilus. Currently Pristoceuthophilus is placed in the tribe Pristoceuthophilini and Ceuthophilus in the tribe Ceuthophilini. Farallonophilus cavernicolus is currently plac...

Abstract The abundance and distribution of Northern anchovy ( Engraulis mordax ) and young of the year (YOY) rockfish ( Sebastes spp.) are critical for the survival and reproduction of seabirds, mammals, and predatory fish within the California Current Ecosystem. Traditional detection and quantification of forage fish by trawling can be time consuming and expensive, and may not provide the spatio-temporal resolution needed to examine ecological relationships in quickly-changing marine environmen...

We provide distribution and abundance information for Farallonophilus cavernicolusRentz, 1972, the Farallon camel cricket, and other commonly encountered ground dwelling arthropods (the tenebrionid beetles Coniontis sp. and Eleodes parvicollis Eschscholtz, 1829, Isopoda, and Microcoryphia) recorded during visits to the Southeast Farallon Island (SEFI) from 2013 through 2015. We found cricket populations in six caves and rock crevices, which were mapped and surveyed. One cave accounted for the gr...

Ocean acidification is a global phenomenon with highly regional spatial and temporal patterns. In order to address the challenges of future ocean acidification at a regional scale, it is necessary to increase the resolution of spatial and temporal monitoring of the inorganic carbon system beyond what is currently available. One approach is to develop empirical regional models that enable aragonite saturation state to be estimated from existing hydrographic measurements, for which greater spatial...

As global climate changes, there is increasing need to understand how changes in the frequencies of environmental variability affect populations. Age-structured populations have recently been shown to filter specific frequencies of environmental variability, favoring generational frequencies, and very low frequencies, a phenomenon known as cohort resonance. However, there has been little exploration of how changes in the spectra of environmental signals will affect the stability and persistence ...

Abstract Effective ecosystem-based fishery management involves assessment of foraging interactions among consumers, including upper level predators such as marine birds and humans. Of particular value is information on predator energetic and consumption demands and how they vary in response to the often volatile dynamics of forage populations, as well as the factors that affect forage availability and potential prey switching. We examined the prey requirements of common murre ( Uria aalge ), Bra...

Individuals increase lifetime reproductive output through a trade-off between investment in future survival and immediate reproductive success. This pattern may be obscured in certain higher quality individuals that possess greater reproductive potential. The Cassin's auklet (Ptychoramphus aleuticus) is a long-lived species where some individuals exhibit greater reproductive ability through a behaviour called double brooding. Here, we analyse 32 years of breeding histories from marked known-age ...
