Genetic data are useful for detecting sudden population declines in species that are difficult to study in the field. Yet this indirect approach has its own drawbacks, including population structure, mutation patterns, and generation overlap. The ivory gull (Pagophila eburnea), a long-lived Arctic seabird, is currently suffering from rapid alteration of its primary habitat (i.e., sea ice), and dramatic climatic events affecting reproduction and recruitment. However, ivory gulls live in remote areas, and it is...

An inventory of crop wild relatives and wild-utilized plants in Canada

In the face of global pressures of change and biodiversity loss, crop wild relatives (CWR) and wild-utilized plants (WUS) urgently require conservation attention. To advance conservation, we assembled a national inventory of CWR and WUS in Canada. To assess current ex situ conservation, we gathered a virtual metacollection of CWR and WUS accession data from national genebanks and from botanical gardens. The inventory includes 779 CWR and WUS taxa (658 distinct species), with 263 (222...

Variation and correlation in the timing of breeding of North Atlantic seabirds across multiple scales

Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, for most populations we lack evidence of strong drivers. Here we adopt an alternative approach, examining the degree to which different populations positively covary in their annual phenology to infer whether phenological responses to environmental drivers are likely to be (i) shared across...
