Using Unoccupied Aerial Vehicles (UAVs) to map and monitor changes in emergent kelp canopy after an ecological regime shiftVienna Saccomanno, Tom Bell, Camille Pawlak, Charlotte Stanley, Rietta Hohman, Kirk Klausmeyer, Kate Cavanaugh, Kyle Cavanaugh, Abby Nickels, Waz Hewerdine, Corey Garza, Gary Fleener & Mary Gleason
Kelp forests are complex underwater habitats that form the foundation of many nearshore marine environments and provide valuable services for coastal communities. Despite their ecological and economic importance, increasingly severe stressors have resulted in declines in kelp abundance in many regions over the past few decades, including the North Coast of California, USA. Given the significant and sustained loss of kelp in this region, management intervention is likely a necessary tool to reset the ecosystem...
Data from: Effects of multiple climate change stressors on gene expression in blue rockfish (Sebastes mystinus)Andrew J. Cline, Scott L. Hamilton & Cheryl A. Logan
Global climate change is predicted to increase the co-occurrence of high pCO2 and hypoxia in upwelling zones worldwide. Yet, few studies have examined the effects of these stressors on economically and ecologically important fishes. Here, we investigated short-term responses of juvenile blue rockfish (Sebastes mystinus) to independent and combined high pCO2 and hypoxia at the molecular level, using changes in gene expression and metabolic enzymatic activity to investigate potential shifts in energy metabolism. Fish were...
Data from: Increased diversity and concordant shifts in community structure of coral-associated Symbiodiniaceae and bacteria subjected to chronic human disturbanceDanielle Claar, Jamie McDevitt-Irwin, Melissa Garren, Rebecca Vega Thurber, Ruth Gates & Julia Baum
Coral-associated bacteria and endosymbiotic algae (Symbiodiniaceae spp.) are both vitally important for the biological function of corals. Yet little is known about their co-occurrence within corals, how their diversity varies across coral species, or how they are impacted by anthropogenic disturbances. Here, we sampled coral colonies (n = 472) from seven species, encompassing a range of life history traits, across a gradient of chronic human disturbance (n = 11 sites on Kiritimati (Christmas) atoll) in...
Data from: Ecosystem function in predator-prey food webs - confronting dynamic models with empirical dataAlva Curtsdotter, H. Thomas Banks, John E Banks, Mattias Jonsson, Tomas Jonsson, Amanda N. Laubmeier, Michael Traugott & Riccardo Bommarco
1. Most ecosystem functions and related services involve species interactions across trophic levels, e.g. pollination and biological pest control. Despite this, our understanding of ecosystem function in multi-trophic communities is poor, and research has been limited to either manipulations in small communities or statistical descriptions in larger ones. 2. Recent advances in food web ecology may allow us to overcome the trade-off between mechanistic insight and ecological realism. Molecular tools now simplify the detection of...
Data from: The molecular biogeography of the Indo-Pacific: testing hypotheses with multispecies genetic patternsEric D. Crandall, Cynthia Riginos, Chris E. Bird, Libby Liggins, Eric Treml, Maria Beger, Paul H. Barber, Sean R. Connolly, Peter F. Cowman, Joseph D. Dibattista, Jeff A. Eble, Sharon F. Magnuson, John B. Horne, Marc Kochzius, Harilaos A. Lessios, Shang Yin Vanson Liu, William B. Ludt, Hawis Madduppa, John M. Pandolfi, Robert R. Toonen, Contributing Members Of Diversity Of The Indo-Pacific Network & Michelle R. Gaither
Aim: To test hypothesized biogeographic partitions of the tropical Indo-Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location: The Indo-Pacific Ocean. Time Period: Pliocene through the Holocene. Major Taxa Studied: 56 marine species. Methods: We tested eight biogeographic hypotheses for partitioning of the Indo-Pacific using a novel modification to analysis of molecular variance. Putative barriers to gene flow emerging from this analysis...
Predation strongly limits demography of a keystone migratory herbivore in a recovering transfrontier ecosystemFred Watson, Matthew Becker, Daan Smit, Egil Droge, Teddy Mukula, Sandra Martens, Shadrach Mwaba, David Christianson, Scott Creel, Angela Brennan, Jassiel M'soka, Angela Gaylard, Chuma Simukonda, Moses Nyirenda & Bridget Mayani
Large herbivore migrations are imperiled globally; however, the factors limiting a population across its migratory range are typically poorly understood. Zambia’s Greater Liuwa Ecosystem (GLE) contains one of the largest remaining blue wildebeest (Connochaetes taurinus taurinus) migrations, yet the population structure, vital rates, and limiting factors are virtually unknown. We conducted a long-term demographic study of GLE wildebeest from 2012–2019 of 107 collared adult females and their calves, 7,352 herd observations, 12 aerial population surveys,...
