Impact of upwelling on phytoplankton blooms and hypoxia along the Chinese coast in the East China Sea
<p>This study evaluates the rarely observed phenomenon of the simultaneous occurrences of phytoplankton blooms, hypoxia, and upwelling along the Zhejiang coast in the East China Sea. Results show that the upwelling uplifted bottom water to 5–10 m below the surface. In the upwelling region, phytoplankton blooms (Chl a = 10.9 μg L−1) occurred and hypoxia or low-oxygen appeared below the surface water. High concentrations of nitrate and phosphate were regenerated in the hypoxic regions, corresponding with mean values (± SD) of 16.9 (± 1.5) and 0.90 (± 0.14) μM, respectively. The upwelling expanded the region of hypoxic water, which nearly reached the surface, thereby increasing the threat to marine life. In addition to fluvial nutrients, the upwelling of water with high nutrient levels, especially phosphates, can enhance phytoplankton blooms. The results suggest that hypoxia can become more severe due to further decomposition of bloom-derived organic matter after blooms crash.</p>

Cascading impacts of earthquakes and extreme heatwaves have destroyed populations of an iconic marine foundation species
<p>Aim: Ecologists traditionally study how contemporary local processes, such as biological interactions and physical stressors, affect the distribution and abundance of organisms. By comparison, biogeographers study the distribution of the same organisms, but focus on historic, larger-scale processes that can cause mass mortalities, such as earthquakes. Here we document cascading effects of rare biogeographical (seismic) and more common ecological (temperature-related) processes on the distribution and abundances of coastal foundation species.</p> <p>Location: Intertidal wave-exposed rocky reefs around Kaikōura, New Zealand, dominated by large, long-lived, and iconic southern bull kelps (<i>Durvillaea antarctica</i> and <i>Durvillaea willana</i>).</p> <p>Methods: In November 2016, a 7.8 Mw earthquake uplifted the coastline around Kaikōura by up to 2 m, and a year later the region experienced the hottest summer on record. Extensive sampling of intertidal communities over 15 km coastline were done shortly after the earthquake and heatwaves and 4 years after the earthquake.</p> <p>Results: <i>Durvillaea</i> lost 75% of its canopy to uplift and the heatwaves reduced canopies that had survived the uplift by an additional 35%. The survey done four years after the earthquake showed that <i>Durvillaea</i> had not recovered, and that the intertidal zone in many places now was dominated by small turfs and foliose seaweed.</p> <p>Main conclusions: Cascading impacts from seismic uplift and heatwaves have destroyed populations of <i>Durvillaea</i> around Kaikōura. Surviving smaller and sparser <i>Durvillaea</i> patches will likely compromise capacity for self-replacement and lower resilience to future stressors. These results are discussed in a global biogeographical-ecological context of seismic activity and extreme heatwaves, and highlight that these events, which are not particularly rare in a geological context, may have common long-lasting ecological legacies.</p>

Canonical analysis showing Praomys mutoni (left-bank specimens only), Praomys minor, and a group of specimens from the Central African Republic (CAR), including two specimens from Kisangani that are craniometrically similar to the CAR specimens (both are classified correctly in the CON-RCA (Congo - central African republic) operational taxonomical unit, OTU, not shown). The percentage of individuals correctly classified by the canonical analysis in the OTU is given in the header, together with the number of individuals correctly classified out of the total number of individuals. The genetic clade is indicated if specimens within the OTU were sequenced.
