Please the survey is directed to people who have some empirical/theoretical
experience in demographic studies and is aware of the regulation/limitation
paradigms as initiated by John Nicholson versus Herbert Andrewartha in the
1930’s or followed by authors like Alan Berryman, Charles Krebs, Robert May,
Anthony Sinclair or Peter Turchin in the last two decades. Thank you

Subject: demographic density-dependence review


Dear listers and colleagues,

WHO: I am a PhD student reviewing the concept of density dependent (DD) in
ecology, under supervision of Corey Bradshaw and Barry Brook at the
University of Adelaide (South Australia).

REQUEST: I am gathering an audience of respondents to a fairly simple
questionnaire dealing with regulation of population size and demographic
density dependent (DD) feedbacks. The results of the questionnaire will be
incorporated in a manuscript in which I am reviewing the use of DD across
taxa and ecosystems in the ecological literature (1980-present).

AIM: Given that many authors have stated that a main cause of the regulation
debate has been terminology, my goal is not to produce new definitions
(which would do nothing but add more unnecessary rhetoric to the debate),
but to assess the degree of consensus in the conceptualization of DD and of
related terms. 

QUESTIONNAIRE DESIGN: a list of closed questions on 4 topics. It should take
you not more than 20 min. to complete. 

HOW: If you are interested in filling the questionnaire, please send me an
e-mail (to me not to the list). Questionnaires will be distributed next week
and would need to be completed within 1 week from reception. 

Looking forward to hearing from you, and many thanks for your time on this

Sincerely,  <mailto:salvador.herrando-perez from adelaide.edu.au> Salva
