Plant community ecology of Tibetan grasslands.

This project is located in Qinghai province, China. Compared to grasslands 
worldwide, Tibetan grasslands have an extremely high level of plant 
diversity, averaging 30-40 species per 0.25m2. In contrast to other 
grasslands, forbs can represent up to 95% of NPP. This unique high alpha, 
high beta diversity and large functional group dominance differences make 
Tibetan plateau grasslands an ideal system to examine mechanisms driving 
plant diversity and plant species coexistence. The Tibetan plateau is also 
characterized by intense above- and belowground herbivory and a long 
evolutionary history of grazing. We hypothesize that this intense herbivory 
by a large array of different herbivores is an important factor driving 
plant diversity. A master’s degree in ecology is preferred. Starting date 
is open and two funded positions are available

My University, Xi'an Jiaotong Liverpool University, is in Suzhou which is 
located close to Shanghai, China, see (http://www.xjtlu.edu.cn/en/). 
Students will receive a Ph D degree from Liverpool University.

Population Biology Postdoctoral Research Fellowship

THE UNIVERSITY OF NEBRASKA-LINCOLN is seeking applications for a 2-year 
postdoctoral position in the Population Biology Program of Excellence.

The goal of the Population Biology-POE Postdoctoral Fellowship is to 
stimulate synergistic interactions between faculty and postdoctoral 
scholars interested in the broad area of Population Biology. We are seeking 
applications from recent PhDs who show promise of conducting cutting edge 
research related to, and expanding upon, faculty research areas in the 
Ecology, Evolution & Behavior (EEB) section in the School of Biological 
Sciences (http://biosci.unl.edu/research-specializations). The POE also 
seeks to identify potential postdoctoral fellows who will enhance graduate 
education, serve as a model for graduate students in career development, 
and promote interactions among faculty at UNL. Qualified candidates are 
required to submit a 2-3 page research proposal detailing the two-year 
program of research to be completed under the guidance of a faculty member 
in the Ecology, Evolution & Behavior (EEB) section in the School of 
Biological Sciences. Applicants are encouraged to reach out to potential 
faculty mentors before developing a proposal for additional guidelines and 
suggestions. The position does not include research funds so the extent of 
contributions from the faculty sponsor should be addressed in the proposal. 
While in residence, the postdoctoral fellow will be expected to lead a 
seminar, symposium or outreach project that will appeal to Population 
Biologists across campus. Applications must include a CV, a 1-page 
description of previous or current research and the description of proposed 
research. In addition, the applicant must arrange for two recommendation 
letters from non-UNL faculty, and one from the UNL faculty sponsor (a total 
of 3 letters) to be emailed to the address below.  The expected salary will 
be $45,000 per year with a start date of August 19, 2018. Priority will be 
given to applicants who have completed their degree and are new to UNL. 
Research descriptions for past and current POE postdoctoral fellows can be 
viewed at http://biosci.unl.edu/population-biology/

Application materials should be emailed to: Dr. Johannes Knops at:

application”.  Applications should be received by March 1, 2018. We 
anticipate notifying the successful applicant by April 1, 2018, with a 
starting date of August 19 or later in 2018. We strongly encourage 
applications from women and members of minority groups. The University of 
Nebraska is committed to a pluralistic campus community through affirmative

[ECOLOG-L] Graduate student opportunity in prairie ecology/restoration in Nebraska

2010-12-02 Thread Johannes Knops
I am looking for a Ph D student interested in vegetation dynamics in prairie 
remnants and prairie restorations. The Nature Conservancy has restored 1,500 
acres of grassland and manages 2,000 acres of remnant prairies and uses 
prescribed fire and grazing to increase habitat quality around Grand Island, 
Nebraska. However, it is increasingly clear that environmental factors such 
as soil composition and fertility, drought susceptibility, site history and 
species pools significant influence the vegetation composition. For 
instance, observationally, we see that remnant prairies are often dominated 
by invasive grasses and are low in forb diversity. Even when subjected to 
years of management to suppress invasive grasses and repeated over-seeding 
attempts, forb diversity fails to increase. Conversely, cropland 
restorations planted with 150-230 species successfully establish diverse 
plant communities. However, these restorations are threatened by the same 
invasive grass species and we see large variation among sites. There seems 
to be environmental variability, presently unaccounted for, that is 
hindering successful efforts to rehabilitate remnant prairies and restored 
prairies. 

We are currently examining how management (including fire and grazing), site 
history and site environmental factors correlate with vegetation 
composition, diversity, and the abundance of at-risk and invasive species. 
For this we have set up 800 permanently marked plots that are annually 
monitored for plant composition and abundance. In addition we have data of 
site history, management, soil fertility, soil texture and will collect 
productivity, nitrogen and water availability data in the next year. Based 
on this we will analyze the factors that control diversity, and propose 
hypotheses for management strategies that increase diversity, decrease the 
prevalence of invasive species, and increase the abundance of at-risk 
species. 

As a next step, we will experimentally examine these hypotheses on factors 
that controls plant diversity and how we may change the competitive balance 
among plant species to favor natives, increase the abundance of rare and 
threatened species, and decrease the prevalence of exotic weeds. 

If you are interested in such a research project for your Ph D, please 
contact me. This requires an interest in both basic and applied community 
and ecosystem ecology.

2010-01-15 Thread Johannes Knops
As part of the University of Nebraska’s Postdoctoral Fellowships in 
Population Biology, we are interested in sponsoring a postdoc working on 
Grassland Plant Population/Community Ecology with the following datasets, 
approach and questions.

Datasets:
•   Old field succession at Cedar Creek NHA in Minnesota. As part of the 
Cedar Creek LTER, we have a dataset of plant cover estimates of 2100 
permanent plots sampled six times since 1983, for plant cover, soil C and N, 
and annually at the field level for insect abundances.
•   Grassland restoration. The Nature Conservancy in Nebraska has 
restored 1,500 acres of grassland and manages 2,000 acres of remnant 
prairies around Grand Island. They have used seeding, prescribed fire and 
grazing to increase habitat quality. We have funding from the Nebraska Game 
and Parks Commission to establish this year permanent plots for a vegetation 
monitoring program. Our goal is to gain a better understanding of the 
factors that control diversity.
•   NUTNET. http://nutnet.science.oregonstate.edu/ We have established 
NUTNET sites at Cedar Point Biological Station and Bartha Brothers Ranch in 
Nebraska. These two sites as well as the entire network consists of a 
factorial addition of N, P and cations to examine nutrient limitation in 
grasslands. 

Approach: 
•   Data analysis, mathematical modeling or a combination.

Questions to address:
•   Controls over and patterns of diversity in relation to environmental 
factors, management or dominant species
•   Scaling from species traits to community modules to community 
composition to ecosystem functioning
•   Importance of environmental fluctuations
•   Other questions of interest to applicant

Consistent with the prior general announcement, applicant selection for the 
two-year position will be based on previous research and potential for 
successful collaboration with an established Population Biologist at UNL 
(see: http://popbio.unl.edu).  

Please contact either one of us ASAP if you have an interest.
