Age‐related trends in niche position and specialization in Neotropical vertebrates
Ecography, EarlyView.Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

Oikos, EarlyView.Partner fidelity is a key component of reproductive strategies in socially monogamous species, yet its adaptive value remains context dependent and poorly understood outside environments with short breeding seasons. In most bird species, partners may remain together or re‐pair between successive nesting attempts, but it remains unclear which components

, 2003 To successfully reproduce in the Arctic, birds must modulate their neuroendocrine and behavioural systems. These adjustments include an attenuation of the stress responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis to external stimuli and a ...

Shifting Balancing Selection Underlies an Inversion Cline in Eurasian Blackcap. [PDF]
Ecol EvolWe investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulation‐based machine learning approach, we found that the inversion is under negative frequency‐dependent selection, and the optimal frequency is shifted ...

Wildlife Biology, EarlyView.Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Songbird Relationships to Shrub-Steppe Ecological Site Characteristics
, 2011 Rangeland managers are often faced with the complex challenge of managing sites for multiple uses and for the diverse interests of stakeholders. Standardized monitoring methods that can be used and understood by different agencies and stakeholders would ...

Wildlife Biology, EarlyView.Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

A comprehensive account of sound sequence imitation in the songbird.
Frontiers in Computational Neuroscience, 2016 The amazing imitation capabilities of songbirds show that they can memorize sensory sequences and transform them into motor activities which in turn generate the original sound sequences.

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains
Wildlife Biology, EarlyView.Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.

Effects of red imported fire ants on songbird nest survival [PDF]
, 2009 Invasive species are often implicated in population declines of native species through competition and predation. Red imported fire ant (Solenopsis invicta) predation of songbird nestlings and eggs has been documented.
