Comment on "Climate-driven ecosystem succession in the Sahara: the past 6000 years".

چکیده
Kröpelin et al. (Research Articles, 9 May 2008, p. 765) interpreted a sediment record from Lake Yoa in the east-central part of North Africa as support for a weak biogeophysical climate-vegetation feedback in the Sahara during the mid-Holocene. We argue that the new data do not invalidate earlier modeling results on strong land-atmosphere coupling in the Western Sahara for which the Lake Yoa record is far less representative.

Comment on “Climate legacies drive global soil carbon stocks in terrestrial ecosystems”
Delgado-Baquerizo et al. (Science Advances, 12 April 2017, e1602008) use statistical correlations to infer that paleoclimate (6000 to 22,000 years ago) is a more important driver of current soil organic carbon stocks than the current-day climate. On the other hand, a wealth of radiocarbon measurements indicates that the organic carbon in most topsoils is only a few decades to perhaps a few cent...
متن کاملGenetic diversity within the Iranian spiny-tailed lizards and predicting species distribution in climate change conditions
There are different methods to investigate the effects of climatic fluctuations on the biota, two of which, molecular phylogeography and SDM, are the most useful tools to trace the past climate induced modifications on species’ geographic distributions. In this study, seven samples were collected from the species distribution range in Iran for the purpose of measuring the genetic variation with...
متن کاملEchoes from the Past: A Healthy Baltic Sea Requires More Effort
Integrated sediment multiproxy studies and modeling were used to reconstruct past changes in the Baltic Sea ecosystem. Results of natural changes over the past 6000 years in the Baltic Sea ecosystem suggest that forecasted climate warming might enhance environmental problems of the Baltic Sea. Integrated modeling and sediment proxy studies reveal increased sea surface temperatures and expanded ...
متن کاملShort communication:Potential ectoparasites of the endemic Mediterranean banded killifish (Aphanius fasciatus, Valenciennes, 1821) of the northern Sahara (Algeria)
The Aphanius fasciatus is an endemic fish species of the coastal Mediterranean region; and recently discovered in the northern Algerian Sahara. The aim of this study is to evaluate the infestation by ectoparasites on A. fasciatus in the new arid habitats where it was newly recorded. For this purpose, skin and gills of 95 fish caught in the Still Wadi (Still river), between September 2012 and Ju...
متن کاملCarbon dynamics in the future forest: the importance of long-term successional legacy and climate-fire interactions.
Understanding how climate change may influence forest carbon (C) budgets requires knowledge of forest growth relationships with regional climate, long-term forest succession, and past and future disturbances, such as wildfires and timber harvesting events. We used a landscape-scale model of forest succession, wildfire, and C dynamics (LANDIS-II) to evaluate the effects of a changing climate (A2...
