Winners and losers: tropical forest tree seedling survival across a West African forest–savanna transition
UNLABELLED Forest encroachment into savanna is occurring at an unprecedented rate across tropical Africa, leading to a loss of valuable savanna habitat. One of the first stages of forest encroachment is the establishment of tree seedlings at the forest-savanna transition. This study examines the demographic bottleneck in the seedlings of five species of tropical forest pioneer trees in a forest...
متن کاملHolocene-Late Pleistocene Climatic Ice Core
Three ice cores to bedrock from the Dunde ice cap on the north-central QinghaiTibetan Plateau ofChina provide a detailed record of Holocene and Wisconsin-Wurm late glacial stage (LGS) climate changes in the subtropics. The records reveal that LGS conditions were apparently colder, wetter, and dustier than Holocene conditions. The LGS part of the cores is characterized by more negative 8180 rati...
متن کاملExplosive Pleistocene diversification and hemispheric expansion of a "great speciator".
Factors that influence speciation rates among groups of organisms are integral to deciphering macroevolutionary processes; however, they remain poorly understood. Here, we use molecular phylogenetic data and divergence time estimates to reconstruct the pattern and tempo of speciation within a widespread and homogeneous bird family (white-eyes, Zosteropidae) that contains an archetypal "great sp...
متن کاملPleistocene climatic fluctuations drive isolation and secondary contact in the red diamond rattlesnake (Crotalus ruber) in Baja California
Editor: Brent Emerson Abstract Aim: Many studies have investigated the phylogeographic history of species on the Baja California Peninsula, and they often show one or more genetic breaks that are spatially concordant among many taxa. These phylogeographic breaks are commonly attributed to vicariance as a result of geological or climatic changes, followed by secondary contact when barriers are n...
متن کاملProjected changes in distributions of Australian tropical savanna birds under climate change using three dispersal scenarios
Identifying the species most vulnerable to extinction as a result of climate change is a necessary first step in mitigating biodiversity decline. Species distribution modeling (SDM) is a commonly used tool to assess potential climate change impacts on distributions of species. We use SDMs to predict geographic ranges for 243 birds of Australian tropical savannas, and to project changes in speci...
