In situ quantification of biogeochemicalprocesses at cold seeps [PDF]

open access: yes, 2009
This thesis focuses on the interaction between microbiology and geochemistry, and the physical driving forces for the biogeochemical cycles in the near-surface sediments of cold seeps. Cold seeps are extraordinary players in the marine realm, harboring a

Diversity of meiofauna at deep-sea hydrothermal vents and cold seeps with particular reference to nematodes

open access: yes, 2007
Deep-sea hydrothermal vents and cold seeps are remarkable for their spectacular megaandmacrofauna, many of which appear to have a high level of endemism to these chemosyntheticenvironments.

Higher Energy Demands and Lower Body Condition in a Hot Spring: Comparing Relict Leopard Frogs at Two Thermally Contrasting Sites

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Following range‐wide decline, all remnant populations of the relict leopard frog (Rana onca) in the eastern Mojave Desert of the southwestern USA occupied geothermally influenced hot springs. In recent years, however, several large populations have been established at cold‐water sites.

Methane emission and consumption at a Noth Sea gas seep (Tommeliten area) [PDF]

open access: yes, 2005
The Tommeliten seepage area is part of the Greater Ekofisk area, which is situated above the Tommeliten Delta salt diapir in the central North Sea (56°29.90' N, 2°59.80' E, Norwegian Block 1/9, 75 m water depth).

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

open access: yesGeophysical Research Letters
Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea.

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Climate Change and Reduction of Soil Organic Layer Thickness Increases Drought Risk in Mountain Forests of the Northern Alps

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Mobilizing Presence across Borders: Devotion to Papua New Guinea's Blessed Peter To Rot in Australia

open access: yesOceania, EarlyView.
ABSTRACT This article engages with the conjunctures between migration and religion by focusing on the celebration of Papua New Guinea's ‘National Patron Saint’, the Blessed Peter To Rot, in the Australian diaspora. Both in Sydney and Brisbane, Catholic Papua New Guinea (PNG) migrants have been ‘relocating’ PNG shrines, regalia, relics and ritual ...
