Adaptation and differentiation across island populations of Berthelot’s pipit (Anthus berthelotii)
… diversity across populations of Berthelot’s pipit (Anthus berthelotii), a passerine bird endemic to the Canary Islands, Selvagens and Madeira archipelagos. To achieve this, I examined variation in pathogen infection, neutral microsatellites and functional major histocompatibility complex …

Landscape Scale Habitat Associations of Sprague's Pipit (Anthus Spragueii) Overwintering in the Southern United States
Sprague's Pipit (Anthus spragueii) is a North American endemic migratory grassland songbird that has experienced a substantial population decline over the last half-century. There has been very limited research done on Sprague’s Pipit especially on their wintering grounds. There is no complete …

Modelling the spatial and temporal dynamics of upland birds in Scotland
… species of upland birds: red grouse, meadow pipit and capercaillie. Populations of red grouse in the British Isles exhibit cyclic fluctuations in abundance. Time series data from 287 grouse moors across the United Kingdom were analysed to investigate co-variation in these fluctuations. …

Going through the motions : the impacts of frequent fires and grazing pressure on reproduction of Montane grassland birds
… grassland bird species (Yellow-breasted Pipit Hemimacronyx chloris, Grassveld Pipit Anthus cinamomerous, Orange-throated Longclaw Macrony capensis, and Ayre's Cisticola Cisticola ayressii). Breeding birds selected nest patches non-randomly and this differed between species. Comparison of …

The Effects of natural Gas Development on Density, Reproductive Success and Nest Survival of Grassland Songbirds in South-Western Saskatchewan
… Vesper Sparrow (Pooecetes gramineus), Sprague’s Pipit (Anthus spragueii), Savannah Sparrow (Passerculus sandwichensis), Baird’s Sparrow (Ammodramus bairdii), Horned Lark (Eremophila alpestris) and Western Meadowlark (Sturnella neglecta). I quantified and compared aspects of their breeding biology …

The spatial scale of immune gene variation within and among bottlenecked populations
… across and within populations of Berthelot’s pipit (Anthus berthelotii), a historically bottlenecked passerine endemic to the oceanic islands of the Canary, Selvagens and Madeira archipelagos. I first investigated the evolution of key innate immune genes among the populations that the pipits …
