Rapid warming in the Gulf of Maine (GoM) is contributing to widespread shifts in the abundance, distribution, and quality of marine prey communities. These shifts cascade up the food web and will ultimately affect the fitness and viability of seabirds, the impacts of which are expected to be especially pronounced at the southern edge of their ranges. Using integrated population models, we analyzed 26 years (1998–2023) of demog...

Conservation of mobile organisms is difficult in the absence of detailed information about movement and habitat use. While the miniaturization of tracking devices has eased the collection of such information, it remains logistically and financially difficult to track a wide range of species across a large geographic scale. Predictive distribution models can be used to fill this gap by integrating both telemetry and census data...

Theory predicts the occurrence of threshold levels of habitat in landscapes, below which ecological processes change abruptly. Simulation models indicate that below critical thresholds, fragmentation of habitat influences patch occupancy by decreasing colonization rates and increasing rates of local extinction. Uncovering such putative relationships is important for understanding the demography of species and in developing sou...
