Livestock grazing promotes ecosystem multifunctionality of a coastal saltmarsh
<p>The effects of livestock grazing on grasslands have garnered much attention; however, little is known about how grazing affects ecosystems' ability to simultaneously support multiple ecosystem functions (i.e., ecosystem multifunctionality, hereafter EMF) in coastal saltmarshes.</p> <p>To comprehensively evaluate the ecological effects of livestock grazing and tidal flooding on saltmarshes, we conducted a grazing-exclusion experiment in the high and middle marsh zones of the Yangtze River Estuary, China.</p> <p>Livestock grazing generally enhanced EMF in the salt marshes, with a stronger impact in the middle marshes than in the high ones. Although plant biomass, aboveground N of plants, soil organic C, and sediment deposition rate decreased under grazing, activities of soil microbes and nematodes, soil N pool, N mineralization, decomposition and soil respiration increased.</p> <p><em>Synthesis and applications.</em> We suggest that tidal flooding and associated replenishment of sediments may mitigate the negative effects of grazing on plants and sedimentation and strengthen positive grazing impacts on nutrient cycling, consequently reinforcing the beneficial effects of livestock grazing on the saltmarsh ecosystem multifunctionality. Our results provide a holistic framework of ecosystem-level responses to livestock grazing in saltmarshes and highlight the regulatory role of external environmental factors such as tidal flooding. Although livestock grazing enhanced the overall EMF of saltmarshes in our study, it was not necessarily desirable for ecosystem services. Integration of ecosystem function-multifunctionality and ecosystem service-multifunctionality of saltmarshes need to be recommended in future multifunctionality studies.</p>
Data from: Possible adverse impact of contaminants on Atlantic cod population dynamics in coastal ecosystems
While many in-lab ecotoxicological studies have shown the adverse impact of pollutants to the fitness of an individual, direct evidence from the field on the population dynamics of wildlife animals has been lacking. Here, we provide empirical support for a negative effect of pollution on Atlantic cod (Gadus morhua) population dynamics in coastal waters of Norway by combining unique time series of juvenile cod abundance, body size, environmental concentration of toxic contaminants, and a spatially structured population dynamics model. The study shows that mercury concentration might have decreased the reproductive potential of cod in the region despite the general decline in the environmental concentration of mercury, cadmium, and hexachlorobenzene since the implementation of national environmental laws. However, some cod populations appeared to be more resistant to mercury pollution than others and the strength and shape of mercury effect on cod reproductive potential was fjord-specific. Additionally, cod growth rate changed at scales smaller than fjords with a gradient related to the exposure to the open ocean and offshore cod. These spatial differences in life history traits emphasize the importance of local adaptation in shaping the dynamics of local wildlife populations. Finally, this study highlights the possibility to mitigate pollution effects on natural population by reducing the overall pollution level but also reveals that pollution reduction alone is not enough to rebuild local cod populations. Cod population recovery probably requires complimentary efforts on fishing regulation and habitat restauration.
Data from: "Hot deals at sea": responses of a top predator (Bottlenose dolphin, Tursiops truncatus) to human-induced changes in the coastal ecosystem
The main response of top predators to human-induced environmental changes is often behavioural. Although human activities regularly impose a disturbance on top predators, they can also be a source of reliable and concentrated food resources for species with a high degree of behavioural plasticity. This study represents the first assessment of the influence of these resources on migratory patterns and social interaction of a marine top predator, the common bottlenose dolphin, Tursiops truncatus. Pollock's closed robust design models and association analyses were applied to data collected over nine consecutive years of research in a coastal area subject to significant use and pressure by humans. Photo-identification data were collected year-round during 955 boat-based surveys, resulting in 1 638 common bottlenose dolphin group encounters. Results of this study revealed a significant upward trend in density of bottlenose dolphins, preferences for a coastal area with higher human pressure, and a reduction of the social interactions associated to a temporal switch to the food sources provided by human activities. The observed link between human activities and changes in common bottlenose dolphin behaviour aim to contribute to a better understanding of the ecology of a marine top predator and provide some of the needed baseline data, from which effective management and conservation strategies can be designed.
