From:Evolution (Vol. 52, Issue 1) Peer-ReviewedThe spatial arrangement of maternally inherited mitochondrial DNA and paternally inherited chloroplast DNA polymorphisms in a permanently marked stand of ponderosa pine was studied. Maternally inherited mtDNA moved only...

From:Ecology (Vol. 81, Issue 7) Peer-ReviewedGREGORY P. ZOGG [1,3] DONALD R. ZAK [1] KURT S. PREGITZER [2] ANDREW J. BURTON [2] Abstract. To determine the importance of microorganisms in regulating the retention of anthropogenic [[NO.sub.3].sup.-], we...

From:Science (Vol. 300, Issue 5627) Peer-ReviewedEver since W. D. Hamilton pointed out that cooperation is facilitated by genetic relatedness (1), kin selection has held a central place in the study of social behavior. Although most cooperative societies comprise...

From:Ecology (Vol. 81, Issue 6) Peer-ReviewedAbstract. A fundamental characteristic of any biological invasion is the speed at which the geographic range of the population expands. This invasion speed is determined by both population growth and dispersal. We...

From:Canadian Journal of Zoology (Vol. 99, Issue 12) Peer-ReviewedThe Coregonus lavaretus (Linnaeus, 1758) complex is a morphologically and genetically diverse group of whitefish. Its taxonomic structure has been controversial for almost a century. At least 25 forms of C. lavaretus...

From:BioScience (Vol. 41, Issue 7) Peer-ReviewedThe foraminifera, shelled protozoans usually less than 1 mm in diameter, exhibit a wide variety of morphology (Figure 1). Benthic foraminifera are distributed in all marine environments from marshes and bays to abyssal...
-
From:Crop Science (Vol. 41, Issue 5) Peer-ReviewedPollen is an important vector of gene flow in maize (Zea mays L.). Experiments were conducted to investigate the duration of pollen viability and the effectiveness of isolation distance for controlling gene flow. Pollen...
-
From:Ecology (Vol. 79, Issue 8) Peer-ReviewedCompetition for pollination is an important factor structuring flowering in many plant communities. We examined mechanisms reducing interspecific pollen flow in a community of 10 Acacia species in a highly seasonal...
-
From:PLoS ONE (Vol. 15, Issue 11) Peer-ReviewedBy considering the role of site-level factors and dispersal, metacommunity concepts have advanced our understanding of the processes that structure ecological communities. In dendritic systems, like streams and rivers,...
-
From:PLoS ONE (Vol. 12, Issue 1) Peer-ReviewedHuman-induced global warming and species introductions are rapidly altering the composition and functioning of Earth's marine ecosystems. Ascidians (Phylum Chordata, Subphylum Tunicata, Class Ascidiacea) are likely to...
-
From:Ecology (Vol. 76, Issue 4) Peer-ReviewedEmpirical studies of the spatial spread of insect pathogens have emphasized the importance of high dispersal rates, but typically rely strictly on observational data. In contrast, existing mathematical models on the...
-
From:Ecology (Vol. 76, Issue 7) Peer-ReviewedThe downstream displacement of individuals by drifting in the current is a prominent feature in the population biology of stream invertebrates. To compensate for the loss of individuals it has been proposed that adults...
-
From:PLoS ONE (Vol. 11, Issue 6) Peer-ReviewedThe wide distribution of many seagrasses may be attributable to exploitation of currents. However, many species have seeds heavier than seawater, limiting surface floating, and thus, deep water becomes a potential...
-
From:Web Ecology (Vol. 1, Issue 1) Peer-ReviewedThe age of dispersers is one of the important factors influencing the ecology and evolution of dispersal. Explanations in textbooks assume special social or genetic advantages to predict the dispersing age class....
-
From:PLoS ONE (Vol. 7, Issue 7) Peer-ReviewedPumice is an extremely effective rafting agent that can dramatically increase the dispersal range of a variety of marine organisms and connect isolated shallow marine and coastal ecosystems. Here we report on a...
-
From:International Journal of Evolutionary BiologyPeer-ReviewedAlthough there is a general consensus on African origin of early modern humans, there is disagreement about how and when they dispersed to Eurasia. This paper reviews genetic and Middle Stone Age/Middle Paleolithic...
-
From:PeerJ (Vol. 6) Peer-ReviewedDispersal and environmental selection are two of the most important factors that govern the distributions of microbial communities in nature. While dispersal rates are often inferred by measuring the degree to which...
-
From:Science (Vol. 296, Issue 5577) Peer-ReviewedThere is considerable public and scientific debate for and against genetically modified (GM) crops. One of the first GM crops, Brassica napus (oilseed rape or canola) is now widely grown in North America, with proposed...
-
From:Ecology (Vol. 78, Issue 2) Peer-ReviewedDispersal behaviors of organisms have been the subject of extensive ecological investigation at both the theoretical and experimental levels. One common framework for field studies of dispersal behavior that can be...
-
From:British Medical Journal (Vol. 316, Issue 7141) Peer-ReviewedOilseed rape (Brassica napus) has been cultivated without problems for centuries, and public suspicion that oilseed rape might have an adverse effect on health arose only when the acreage of this crop rapidly increased...
