Impacts on coral reefs in Oman were found to be attributable to both natural and human causes, resulting in significant and widespread degradation. Damage resulting from fisheries activities was the most commonly recorded human impact, with the most severe effects. Other human impacts resulted from ...

However, these climate change-driven declines are outweighed by the impact of deforestation. Consequently, our analyses suggest that regional land-use management is more important than mediating climate change for influencing sedimentation of Malagasy coral reefs....
High impact threats most tractable to regional management relate to ship traffic. Sensitivity analyses show that the results are robust to both data availability and quality. Managers can use these maps to (1) inform management and surveillance priorities based on the ranking of threats and their ...

nourishment predominantly impact coastal food webs from the bottom up; predators are affected by reduction in the abundance and diversity of their prey (Chapman et al.2009; Vargas-Fonseca et al.2016). These effects reduce the prevalence and abundance of sensitive species, especially larger predators...
Impacts of human activities on the ocean have been shown to be substantial, ubiquitous1 and changing2. The resulting cumulative impact of these activities often leads to ecosystem degradation or even collapse3,4,5,6,7, and studies of individual marine ecosystems (e.g., coral reefs, kelp fores...
However, much less evidence has been gathered on the impact of invasions and extinctions on the functional facet of biodiversity (Matsuzaki et al., 2013), or on its relationship with co-occurring changes in taxonomic dissimilarity among assemblages (Villéger et al., 2014). Therefore, it will ...
Climate change - Human Impact, Causes, Effects: The history of humanity—from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human species (Homo sapiens) beginning some 150,000 years ago—is integr
Forest-grassland mosaic ecosystems can exhibit alternative stables states, whereby under the same environmental conditions, the ecosystem could equally well reside either in one state or another, depending on the initial conditions. We develop a mathemat
