In this short note I have tried to make clear the issues surrounding a recent discussion on changing-radius paleobiogeographical problems of the Pacific Ocean biotic distribution. It is stressed that ...
Biodiversity is Biogeography:Implications for Conservation
Biodiversity Biogeography Conservation
2015/8/13
Three themes dominate this review. The first is that biodiversity is biogeography. Or, as Nelson and Ladiges (1990) put it: "Indeed, what beyond biogeography is 'biodiversity' about?" Second, watershe...
Penguin Biogeography Along the West Antarctic Peninsula: Testing the Canyon Hypothesis with Palmer LTER Observations
West Antarctic Peninsula Canyon Hypothesis
2015/7/16
The West Antarctic Peninsula (WAP) is home to large breeding colonies of the ice-dependent Antarctic Adélie penguin (Pygoscelis adeliae). Although the entire inner continental shelf is highly producti...
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation
Iron phosphorus nitrogen fixation
2014/4/2
We present a unified conceptual framework describing the competition between diazotrophs and non–
nitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...

Biostratigraphy Biogeography Early vertebrates Siluro-Devonian China
2014/3/26
During the past three decades, early vertebrates from the mid-Paleozoic of China have attracted extensive attention on account of their distinc-tive anatomical features, high diversity, early stratigr...

Biodiversity and Biogeography of Hydrothermal Vent Species: Thirty Years of Discovery and Investigations
Hydrothermal vents animal microbial community exploration the bottom of the sea
2015/7/22
The discovery of hydrothermal vents and the unique, often endemic fauna that inhabit them represents one of the most extraordinary scientific discoveries of the latter twentieth century. Not surprisin...
Biogeography of major bacterial groups in the Delaware estuary
Biogeography major bacterial groups Delaware estuary
2014/5/13
We used fluorescence in situ hybridization to examine the spatial and temporal variation in the abundance of major bacterial groups in the Delaware Estuary. The abundance of alpha- and beta-proteobact...
Genetic diversity in the Gammarus pecos species complex: Implications for conservation and regional biogeography in the Chihuahuan Desert
Genetic diversity Gammarus pecos species complex conservation and regional biogeography Chihuahuan Desert
2014/5/14
We used allozyme electrophoresis to quantify genetic variation in nine populations of the Gammarus pecos species complex endemic to spring systems of the northern Chihuahuan Desert. There was signific...
