Asymmetric responses of N-cycling gene to increased and decreased precipitation in arid grasslands

Mengying Zhao, Haihua Shen, Yankun Zhu, Aijun Xing, Jie Kang, Lingli Liu, Jingyun Fang This is a plain language summary of a Functional Ecology research article which can be found here. Soil microbes are important drivers of the nitrogen (N) cycle, and carry a variety of functional genes encoding corresponding enzymes associated with N turnover. Precipitation changes can greatly alter the soil N cycle, with … Continue reading Asymmetric responses of N-cycling gene to increased and decreased precipitation in arid grasslands

Nitrogen-induced phosphorus limitation affects soil carbon cycling

Min Luo, Daryl L. Moorhead, Raúl Ochoa-Hueso, Carsten W. Mueller, Samantha C. Ying, Ji Chen This is a plain language summary of a Functional Ecology review article which can be found here. Fossil fuel combustion and agricultural fertilization have more than doubled natural levels of reactive nitrogen (N) inputs to terrestrial ecosystems, whereas the input of phosphorus (P) is relatively small. These unbalanced N and … Continue reading Nitrogen-induced phosphorus limitation affects soil carbon cycling

Soil nitrogen supply capacity of different plateau grasslands 

Shuya Hu, Changhui Wang, Anita C Risch, Yuan Liu, Yang Li, Lei Li, Xiaohui Xu, Nianpeng He, Xingguo Han, Jianhui Huang This is a plain language summary of a Functional Ecology research article which can be found here. Soil nitrogen (N) supply capacity is a key biogeochemical process influencing plant available N and net primary productivity (NPP) in terrestrial ecosystems. However, the spatial variations and … Continue reading Soil nitrogen supply capacity of different plateau grasslands

Individual tree species within a mixed forest drive its nutrient use efficiency

Tania L. Maxwell, Nicolas Fanin, William C. Parker, Mark R. Bakker, Ariane Belleau, Céline Meredieu, Laurent Augusto, Alison D. Munson This is a plain language summary of a Functional Ecology research article that can be found here. Increasing the number of tree species within a forest has been shown to improve nutrient cycling due to factors such as complementarity between species that vary in structure … Continue reading Individual tree species within a mixed forest drive its nutrient use efficiency

The importance of soil bacteria related to N cycle in eucalyptus plantations under the near-natural management model

Zhao-lei Qu, Bing Liu, Yue-mei Zhang, Lin Huang, An-gang Ming, Hui Sun This is a plain language summary of a Functional Ecology research article that can be found here. Eucalyptus, due to its fast growth and high yield of commercial timber, is widely planted in China, especially in Guangxi province, a mountainous region in the far south of China. However, inappropriate plantation management strategies (e.g., … Continue reading The importance of soil bacteria related to N cycle in eucalyptus plantations under the near-natural management model

Active revegetation does not impact the nitrogen removal efficiency of a riparian zone

Lu Yao, Yu Gong, Chen Ye, Wenjun Shi, Kerong Zhang, Ming Du, Quanfa Zhang This is a plain language summary of a Functional Ecology research article that can be found here. Riparian zones, where the land meets rivers or streams, are the aquatic-terrestrial interface which can improve water quality by removing nitrogen via denitrification processes. Riparian zones are also some of the most degraded and … Continue reading Active revegetation does not impact the nitrogen removal efficiency of a riparian zone

Soil nutrient availability and tree height control the physiology of the world’s tallest tropical trees

David Bartholomew, Lindsay Banin, Paulo Bittencourt, Mohd Aminur Faiz Suis, Lina Mercado, Reuben Nilus, David Burslem, Lucy Rowland This is a plain language summary of a Functional Ecology research article which is published here. The tropical forests of Borneo in South-East Asia possess exceptionally high levels of biodiversity, act as important carbon stores and are home to the world’s tallest tropical trees. However, these characteristics … Continue reading Soil nutrient availability and tree height control the physiology of the world’s tallest tropical trees

Nitrogen fixation and input associated with mosses in tropical mountain cloud forests will decline in a future climate

Aya Permin, Aline B. Horwath, Daniel B. Metcalfe, Anders Priemé, Kathrin Rousk This is a plain language summary of a Functional Ecology research article that is published here. All life needs nitrogen (N) and in many terrestrial ecosystems, N enters via the process of biological N fixation. In this process, certain groups of bacteria transform the atmospheric N gas, inaccessible to organisms, into bioavailable N … Continue reading Nitrogen fixation and input associated with mosses in tropical mountain cloud forests will decline in a future climate

Soil acidification suppresses multiple ecosystem functions

Yanan Wei, Xin Jing, Fanglong Su, Zhen Li, Fuwei Wang, Hui Guo This is a plain language summary of a Functional Ecology research article which is published here. Globally, higher inputs of acid rain and fertilization cause lower soil pH values, i.e., soil acidification. The decreased soil pH may broadly influence both above- and belowground biota and their habitats, exerting substantial effects on multiple ecosystem … Continue reading Soil acidification suppresses multiple ecosystem functions
