Terborgh, Duke University, Durham, NC, and approved August 5, 2015 (received for review March 16, 2015) Loss of megafauna, an aspect of defaunation, can precipitate many megafauna loss, and if so, what does this loss imply for the future ecological changes over short time scales. We examine whether of ecosystems at risk for losing their megafauna today? megafauna loss can also explain features of lasting ecological state shifts that occurred as the Pleistocene gave way to the Holocene. We Approach compare ecological impacts of late-Quaternary megafauna extinction The late-Quaternary impact of losing 70–80% of the megafauna in five American regions: southwestern Patagonia, the Pampas, genera in the Americas (19) would be expected to trigger biotic northeastern United States, northwestern United States, and Berin- transitions that would be recognizable in the fossil record in at gia.

However, terrestrial carbon fluxes remain the largest uncertainty in the global carbon cycle. Here, we develop spatially explicit estimates of carbon stock changes of live woody biomass from 2000 to 2019 using measurements from ground, air, and space. We show that live biomass has removed 4.9 to −1 −1 5.5 PgC year from the atmosphere, offsetting 4.6 ± 0.1 PgC year of gross emissions from disturbances and −1 adding substantially (0.23 to 0.88 PgC year ) to the global carbon stocks. Gross emissions and removals in the tropics were four times larger than temperate and boreal ecosystems combined. Although live biomass is responsible for more than 80% of gross terrestrial fluxes, soil, dead organic matter, and lateral transport may play important roles in terrestrial carbon sink. -

Ecological Consequences of Human Niche Construction: Examining Long-Term Anthropogenic Shaping of Global Species Distributions Nicole L
SPECIAL FEATURE: SPECIAL FEATURE: PERSPECTIVE PERSPECTIVE Ecological consequences of human niche construction: Examining long-term anthropogenic shaping of global species distributions Nicole L. Boivina,b,1, Melinda A. Zederc,d, Dorian Q. Fuller (傅稻镰)e, Alison Crowtherf, Greger Larsong, Jon M. Erlandsonh, Tim Denhami, and Michael D. Petragliaa Edited by Richard G. Klein, Stanford University, Stanford, CA, and approved March 18, 2016 (received for review December 22, 2015) The exhibition of increasingly intensive and complex niche construction behaviors through time is a key feature of human evolution, culminating in the advanced capacity for ecosystem engineering exhibited by Homo sapiens. A crucial outcome of such behaviors has been the dramatic reshaping of the global bio- sphere, a transformation whose early origins are increasingly apparent from cumulative archaeological and paleoecological datasets. Such data suggest that, by the Late Pleistocene, humans had begun to engage in activities that have led to alterations in the distributions of a vast array of species across most, if not all, taxonomic groups. Changes to biodiversity have included extinctions, extirpations, and shifts in species composition, diversity, and community structure. We outline key examples of these changes, highlighting findings from the study of new datasets, like ancient DNA (aDNA), stable isotopes, and microfossils, as well as the application of new statistical and computational methods to datasets that have accumulated significantly in recent decades. We focus on four major phases that witnessed broad anthropogenic alterations to biodiversity—the Late Pleistocene global human expansion, the Neolithic spread of agricul- ture, the era of island colonization, and the emergence of early urbanized societies and commercial net- works. -

Nonetheless, deforestation continues, and seemingly intact forest areas are being degraded. Furthermore, REDD+ may fail to consider the crucial ecosystem functions of forest fauna including seed dispersal and pollination. Throughout the tropics, forest animal populations are depleted by unsustainable hunting to the extent that many forests are increasingly devoid of larger mammals—a condition referred to as empty forests. -

We show that between 2000 License 4.0 (CC BY-NC). and 2013, direct clearance of intact tropical forest areas accounted for 3.2% of gross carbon emissions from all deforestation across the pantropics. However, full carbon accounting requires the consideration of forgone carbon sequestration, selective logging, edge effects, and defaunation. When these factors were considered, the net carbon impact resulting from intact tropical forest loss between 2000 and 2013 increased by a factor of 6 (626%), from 0.34 (0.37 to 0.21) to 2.12 (2.85 to 1.00) petagrams of carbon (equivalent to approximately 2 years of global land use change emissions).

Newman* Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ, United States With the accumulating evidence of changing disturbance regimes becoming increasingly obvious, there is potential for disturbance ecology to become the most valuable lens through which climate-related disturbance events are interpreted. In this paper, I revisit some of the central themes of disturbance ecology and argue that the knowledge established in the field of disturbance ecology continues to be relevant to ecosystem management, even with rapid changes to disturbance regimes and changing disturbance types in local ecosystems. Disturbance ecology has been tremendously successful over the past several decades at elucidating the interactions between disturbances, biodiversity, and ecosystems, and this knowledge can be leveraged in different contexts. Primarily, management in changing and uncertain conditions should be focused primarily on the long-term persistence of that native biodiversity that has evolved within the local disturbance regime and is likely to go extinct with rapid changes to disturbance intensity, frequency, and type. -
