TL;DR: Paleoecological, archaeological, and historical data show that time lags of decades to centuries occurred between the onset of overfishing and consequent changes in ecological communities, because unfished species of similar trophic level assumed the ecological roles of over-fished species until they too were overfished or died of epidemic diseases related to overcrowding as mentioned in this paper.

TL;DR: The conditions in which kelp forests develop globally and where, why and at what rate they become deforested are reviewed and overfishing appears to be the greatest manageable threat to kelp forest ecosystems over the 2025 time horizon.

TL;DR: Evidence suggests that aquatic and maritime adaptations played a significantly greater role in the demographic and geographic expansion of anatomically modern humans after about 150,000 years ago.

TL;DR: This work focuses on four major phases that witnessed broad anthropogenic alterations to biodiversity—the Late Pleistocene global human expansion, the Neolithic spread of agriculture, the era of island colonization, and the emergence of early urbanized societies and commercial networks.

TL;DR: It is proposed that one or more large, low-density ET objects exploded over northern North America, partially destabilizing the Laurentide Ice Sheet and triggering YD cooling, which contributed to end-Pleistocene megafaunal extinctions and adaptive shifts among PaleoAmericans in North America.
