Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms
Darras, Kevin F. A.; Rountree, Rodney A.; Van Wilgenburg, Steven L.; Cord, Anna F.; Pitz, Frederik; Chen, Youfang; Dong, Lijun; Rocquencourt, AgnèsAim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. ...
The biogeography of community assembly: latitude and predation drive variation ...
Gross, Collin P.; Duffy, J. Emmett; Hovel, Kevin A.; Kardish, Melissa R.; Reynolds, Pamela L.; Boström, Christoffer; Boyer, Katharyn E.; Cusson, MathieuWhile considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Studying how the distributions of traits in communities vary along global gradients can inform how variation in interactions and other factors contribute to the process of community assembly. Using a model selection approach on ...
A Pleistocene legacy structures variation in modern seagrass ecosystems
Duffy, J. Emmett; Stachowicz, John J.; Reynolds, Pamela L.; Hovel, Kevin A.; Jahnke, Marlene; Sotka, Erik E.; Boström, Christoffer; Boyer, Katharyn E.Distribution of Earth's biomes is structured by the match between climate and plant traits, which in turn shape associated communities and ecosystem processes and services. However, that climate-trait match can be disrupted by historical events, with lasting ecosystem impacts. As Earth's environment changes faster than at any time in human history, critical questions are whether and how organismal traits and ec...
Latitude, temperature, and habitat complexity predict predation pressure in eel...
Reynolds, Pamela L.; Stachowicz, John J.; Hovel, Kevin; Bostrom, Christoffer; Boyer, Katharyn; Cusson, Mathieu; Eklof, Johan S.; Engel, Friederike G.Latitudinal gradients in species interactions are widely cited as potential causes or consequences of global patterns of biodiversity. However, mechanistic studies documenting changes in interactions across broad geographic ranges are limited. We surveyed predation intensity on common prey (live amphipods and gastropods) in communities of eelgrass (Zostera marina) at 48 sites across its Northern Hemisphere rang...
Harnessing positive species interactions as a tool against climate-driven loss ...
Bulleri, Fabio; Eriksson, Britas Klemens; Queiros, Ana; Airoldi, Laura; Arenas, Francisco; Arvanitidis, Christos; Bouma, Tjeerd J.; Crowe, Tasman P.Habitat-forming species sustain biodiversity and ecosystem functioning in harsh environments through the amelioration of physical stress. Nonetheless, their role in shaping patterns of species distribution under future climate scenarios is generally overlooked. Focusing on coastal systems, we assess how habitat-forming species can influence the ability of stress-sensitive species to exhibit plastic responses, a...
Biodiversity mediates top-down control in eelgrass ecosystems: a global compara...
Duffy, J. Emmett; Reynolds, Pamela L.; Bostroem, Christoffer; Coyer, James A.; Cusson, Mathieu; Donadi, Serena; Douglass, James G.; Ekloef, Johan S.Nutrient pollution and reduced grazing each can stimulate algal blooms as shown by numerous experiments. But because experiments rarely incorporate natural variation in environmental factors and biodiversity, conditions determining the relative strength of bottom-up and top-down forcing remain unresolved. We factorially added nutrients and reduced grazing at 15 sites across the range of the marine foundation sp...
