Biogeographic variation in environmental and biotic resistance modifies predicted risk of marine invasions by ships Open
Introduction Global shipping has accelerated the spread of non-native species. Factors such as environmental filtering and interactions with local biota can affect invasion likelihood, yet their relative contribution to predicting invasion…

Biogeographic and seasonal differences in consumer pressure underlie strong predation in the tropics Open
Biotic interactions play a critical role in shaping patterns of global biodiversity. While several macroecological studies provide evidence for stronger predation in tropical regions compared with higher latitudes, results are variable eve…

When species don’t move together: Non-concurrent range shifts in Eastern Pacific kelp forest communities Open
Species range shifts due to changing ocean conditions are occurring around the world. As species move, they build new interaction networks as they shift from or into new ecological communities. Typically, species ranges are modeled individ…

Habitat isolation interacts with top-down and bottom-up processes in a seagrass ecosystem Open
Habitat loss is accelerating at unprecedented rates, leading to the emergence of smaller, more isolated habitat remnants. Habitat isolation adversely affects many ecological processes independently, but little is known about how habitat is…

Predation facilitates the abundance of biofouling non-indigenous species in estuarine marinas in NE Atlantic Portugal Open
Harbours are highly modified habitats that differ from natural areas. They are hotspots of non-indigenous species (NIS) and act as stepping-stones in invasive processes. However, local communities can exert biotic resistance against biolog…

Biotic interactions shape trait assembly of marine communities across time and latitude Open
Assembly processes are highly dynamic with biotic filters operating more intensely at local scales, yet the strength of biotic interactions can vary across time and latitude. Predation, for example, can be stronger at lower latitudes, whil…

Extreme Weather Preparedness for Institutions of Higher Education Open
BACKGROUND: On September 1, 2021, a tornado touched down at Temple University’s Ambler, PA campus. The tornado, a byproduct of Hurricane Ida, damaged most of the buildings on the campus, destroyed thousands of academic resources and killed…

Asymmetry of marine invasions across tropical oceans Open
Understanding the mechanisms of spatial variation of biological invasions, across local‐to‐global scales, has been a major challenge. The importance of evolutionary history for invasion dynamics was noted by Darwin, and several studies hav…

A New Field Station, Footsteps from Philadelphia Open
The Temple Ambler Field Station, located just 40 minutes outside of Philadelphia, Pennsylvania, offers new opportunities for environmental field research and education (Fig. 1). Temple University’s Ambler Campus was officially designated a…

Predation shapes invertebrate diversity in tropical but not temperate seagrass communities Open
The hypothesis that biotic interactions are stronger at lower relative to higher latitudes has a rich history, drawing from ecological and evolutionary theory. While this hypothesis suggests that stronger interactions at lower latitudes ma…

Multi-trophic native and non-native prey naïveté shape marine invasion success Open
Invasive predators have caused rapid declines in many native prey species across the globe. Predator invasion success may be attributed to prey naïveté, or the absence of anti-predator behavior between native and non-native species. An und…

Prior predation alters community resistance to an extreme climate disturbance Open
Short‐term physical disturbances occur amid a backdrop of longer‐term biotic interactions, including predation, which shape communities. Effects of consumer interactions typically begin in early stages of assembly and continue throughout p…
