The concentration of dissolved oxygen in aquatic systems helps to regulate biodiversity1,2, nutrient biogeochemistry3, greenhouse gas emissions4, and the quality of drinking water5.
Unravelling winter diatom blooms in temperate lakes using high frequency data and ecological modeling
temperate lakes winter diatom blooms winter phytoplankton ecological mode
2021/7/27
In temperate lakes, it is generally assumed that light rather than temperature constrains phytoplankton growth in winter. Rapid winter warming and increasing observations of winter blooms warrant more...
Major group of flowering plants is evolving twice as quickly in temperate zones as in the tropics（图）
Major group flowering plants evolving twice quickly temperate zones tropics
2020/7/10
In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as in the tropics. The finding runs counter to a long-held hypothesis that tropical regions, home...
Trophic Relationships and Diet of Consumers in Temperate Kelp Forest and Coral Reef Ecosystems
Temperate Kelp Forest Coral Reef Ecosystems
2015/7/16
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...
Increased temperature and precipitation interact to affect root production, mortality, and turnover in a temperate steppe: implications for ecosystem C cycling
precipitation root mortality root production root turnover temperate grassland warming
2015/2/5
Fine root production and turnover play important roles in regulating carbon (C) cycling in terrestrial ecosystems. In order to examine effects of climate change on root production and turnover, a fiel...
Modeling dissolved organic carbon in temperate forest soils: TRIPLEX-DOC model development and validation
Modeling dissolved organic carbon temperate forest soils
2014/12/18
Even though dissolved organic carbon (DOC) is
the most active carbon (C) cycling in soil organic carbon
(SOC) pools, it receives little attention from the global C
budget.
TURNING UP THE HEAT ON THE LITTLE THINGS THAT RUN THE WORLD: EVALUATING THE IMPACTS OF CLIMATE CHANGE ON ANT BIODIVERSITY IN THE TEMPERATE FOREST COMMUNITIES OF THE NORTHEASTERN UNITED STATES
Biodiversity Climate Change Ants Ecology Biogeography Macroecology
2014/12/18
Climatic change threatens biodiversity worldwide. In the forests of the northeastern United States, climate change is expected to increase mean annual temperatures by up to 4.5˚C and change preci...
Long-term vegetation changes in a temperate forest impacted by climate change
Alaska biodiversity Callitropsis nootkatensis
2015/11/13
Pervasive forest mortality is expected to increase in future decades as a result of increasing
temperatures. Climate-induced forest dieback can have consequences on ecosystem services, potentially
m...
Precise determination of Sr/Ca by laser ablation ICP-MS compared to ICP-AES and application to multi-century temperate corals
coral Sr/Ca laser ablation ICP-MS ICP-AES
2017/4/11
Coral skeletal Sr/Ca compositions are valuable tools for the reconstruction of past tropical climate. While solutionbased
ICP-AES has become the preferred method to obtain monthly-resolved Sr/Ca reco...

Nitrogen enrichment increases net silica accumulation a temperate salt marsh
2014/4/2
Two New England salt marshes exposed to different N availability were assessed seasonally for 1 yr, creating the first complete salt marsh Si budgets. Triplicate seasonal measurements were collected f...
Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
Genomic Analyses of Toll-like Receptor 4 and 7 Exons of Bos indicus from Temperate Sub-himalayan Region of India
Bovine TLR 4 TLR 7 Exons LRR Innate Immunity Sequence Analyses
2016/5/6
Toll-like receptors (TLRs) play an important role in the recognition of invading pathogens and the modulation of innate immune responses in mammals. The TLR4 and TLR7 are well known to recognize the b...
Partitioning of primary production among giant kelp (Macrocystis pyrifera), understory macroalgae, and phytoplankton on a temperate reef

2014/4/4
We experimentally investigated the response of phytoplankton and understory macroalgae to canopies of giant
kelp, Macrocystis pyrifera, by following changes in their biomass and net primary productio...
Effect of a flood event on the dynamics of phytoplankton and biogeochemistry in a large temperate Australian lagoon

2014/4/17
In episodically driven estuaries, nutrient delivery is typically confined to sporadic flow events, followed by intense biogeochemical recycling of nutrients. We document the response of a temperate la...
