Photo: Cover Photo: An Eagle Owl (Bubo bubo), the largest owl in the world,
has killed an adult Black Kite (Milvus migrans), a medium-sized diurnal raptor.
Proximity to the nest site of an Eagle Owl increases the probability of predation
for Black Kites, and is an integral component of territory quality for this
species. Kites have a very limited time to assess and choose a territory when
they return from spring migration, a problem that is exacerbated for inexperienced
individuals occupying a territory for the first time. Such individuals may resort
to cues such as the presence, abundance, and breeding performance of conspecifics
in previous years. The photograph was taken as part of a study conducted in
the Italian Alps by F. Sergio and V. Penteriani, Public information and
territory establishment in a loosely colonial raptor, to be published
in Ecology Volume 86(2), February 2005. Click on the photo for more photographs

AIMS
The Ecological Society of
America was founded in 1915 for the purpose of unifying the sciences of
ecology, stimulating research in all aspects of the discipline, encouraging
communication among ecologists, and promoting the responsible application
of ecological data and principles to the solution of environmental problems.
Ecology is the scientific discipline that is concerned with the relationships
between organisms and their past, present, and future environments. These
relationships include physiological responses of individuals, structure
and dynamics of populations, interactions among species, organization
of biological communities, and processing of energy and matter in ecosystems.

EDITORIAL
| I became a member of ESA
as a graduation gift from Dan Kozlowsky (A critical evaluation of
the trophic level concept. I. Ecological efficiencies. Ecology 49:4860,
1968 ). I had, since my freshman year at the University of Wisconsin,
been an avid reader of Ecology and Ecological Monographs. In fact every
Friday afternoon I would, as a treat, go to the library and take one or
two volumes and read the articles I felt were important. This, of course,
meant that as I worked my way through the volumes, I often went back to
volumes I had already looked at to reread articles whose value I now understood
and appreciated. I knew the Society mainly through its science journals. Consequently, when I received my first Bulletin, I realized that ESA really was a community of scholars. The Bulletin was at the time moving from being a vehicle to report the deadly boring minutes of Council meetings, the resolutions of respect, and the programs and abstracts of Annual Meetings, to having more general articles that discussed issues facing the Society that did not fit into the scholarly journals. These changes increased in tempo in the 12 years Allen Solomon was Editor-in-Chief of the Bulletin. He instituted a large number of innovations that made the Bulletin more a must read by all members. However, Allens most important contribution will be seen as making the Bulletin electronic. An electronic Bulletin has many interesting possibilities that the paper Bulletin did not have. We can put in more pictures, links can be made directly to meeting web sites, articles mentioned can be linked directly (in many cases), to computer programs and useful subroutines can be downloaded, PowerPoint material for lectures and seminars can be made available, even short videos can be incorporated. These technological opportunities should increase the Bulletins usefulness. |
However, technology will
not make the Bulletin necessary. If one reads the Visions
Committee report www.esa.org/ecovisions, one message runs
throughout. ESA must reach out to a wider audience. The Society actually
started doing this before the Visions Committee by developing a new journal,
Frontiers in Ecology and the Environment under the founding
Editor-in-Chief, Sue Silver. Frontiers has clearly filled
an empty niche in both ESA and in wider ecology and environmental communities.
In this issue of the Bulletin, you will find several new columns. I have
asked Susan Barker and Charles Anderson to edit a column that will be
of use to teachers, with articles that will bridge the gap between research
in the science of ecology and the needs and concerns of teachers. This
will include how students learn and understand ecology. I would also like
to start a similar column directed at ecologists who are environmental
consultants. David Inouye will now be assisted by Sam Scheiner in editing
the Technological Tools column under its new name, Emerging Technologies.
This will help keep us up-to-date on areas not in our speciality. I have
also asked the International Section to increase our international coverage,
particularly of what other ecological societies are doing. Finally, I
am starting a column that gives background and commentary on significant,
recently published ecological science papers. Ecology is now such a diverse
and eclectic field it is difficult to understand the significance of developments
in all parts of the discipline. I hope that this feature will keep us
aware. The Society owes Allen Solomon a large debt for his work for ESA over the last 12 years and for decades before. I have known Al since the 1970s, but I always remember him with a smile for a paper he gave at an Annual Meeting in the 1980s; the subject was the paleoecology of Lake Woebegone. E. A. Johnson |

Murray F. Buell Award and E. Lucy Braun Award
Murray
F. Buell had a long and distinguished record of service and accomplishment
in the Ecological Society of America. Among other things, he ascribed great
importance to the participation of students in meetings and to excellence
in the presentation of papers. To honor his selfless dedication to the younger
generation of ecologists, the Murray F. Buell Award for Excellence in Ecology
is given to a student for the outstanding oral paper presented at the ESA
Annual Meeting.
E.
Lucy Braun, an eminent plant ecologist and one of the charter members of the
Society, studied and mapped the deciduous forest regions of eastern North
America and described them in her classic book, The Deciduous Forests of
Eastern North America. To honor her, the E. Lucy Braun Award for Excellence
in Ecology is given to a student for the outstanding poster presentation at
the ESA Annual Meeting.
A
candidate for these awards must be an undergraduate, a graduate student, or
a recent doctorate not more than 9 months past graduation at the time of the
meeting. The paper or poster must be presented as part of the program sponsored
by the Ecological Society of America, but the student need not be an ESA member.
To be eligible for these awards the student must be the sole or senior author
of the oral paper (Note: symposium talks are ineligible) or poster. Papers
and posters will be judged on the significance of ideas, creativity, quality
of methodology, validity of conclusions drawn from results, and clarity of
presentation. While all students are encouraged to participate, winning papers
and posters typically describe fully completed projects. The students selected
for these awards will be announced in the ESA Bulletin following the
Annual Meeting. A certificate and a check for $500 will be presented to each
recipient at the next ESA Annual Meeting.
If
you wish to be considered for either of these awards at the 2005 Annual Meeting,
you must send the following to the Chair of the Student Awards Subcommittee:
(1) the application form below, (2) a copy of your abstract, and (3) a 250-word
or less description of why/how the research presented will advance the field
of ecology. Because of the large number of applications for the Buell and
Braun awards in recent years, applicants may be prescreened prior to the meeting,
based on the quality of the abstract and this description of the significance
of their research. The application form, abstract, and research justification
must be sent by mail, fax, or email (e-mail is preferred; send e-mail to sacchi@kutztown.edu)
to the Chair of the Student Awards Subcommittee: Dr. Christopher F. Sacchi,
Department of Biology, Kutztown University of PA, Kutztown, PA 19530 USA.
If you have questions, write, call (610) 683-4314, fax (610) 683-4854, or
email: sacchi@kutztown.edu. You
will be provided with suggestions for enhancing a paper or poster. The deadline
for submission of form and abstract is 1 March 2005; applications sent after
1 March 2005 will not be considered. This submission is in addition to the
regular abstract submission. Buell/Braun participants who fail to notify the
B/B Chair by 1 May of withdrawal from the meeting will be ineligible, barring
exceptional circumstances, for consideration in the future. Electronic versions
of the Application Form are available on the ESA web site, or you can send
an e-mail to sacchi@kutztown.edu and request that an
electronic version be sent to you as an attachment.

Ramón Margalef, Professor Emeritus of Ecology at the University
of Barcelona, Spain, passed away on 23 May 2004, four days after his
85th birthday. His wife, María Mir, whom he had met at the
university and married in 1952, died suddenly on 30 May 2004, just
one week after her husband. They had four children. Ramón Margalef
was Spains most important ecologist, and one of the worlds
prominent limnologists, marine biologists, and theoretical ecologists
of the 20th century. He was a pioneer in his own right, and made outstanding
contributions to these and other fields (e.g., biogeography, geology,
animal behavior, human evolution, and human ecology), leaving us an
enormous body of scientific literature consisting of about 400 articles
and 20 books and monographs. Taken together, this formidable scientific
production laid the foundations of a comprehensive, coherent ecological
theory. His scientific ideas have had a significant influence on several
generations of ecologists, both through teaching (in Spain and elsewhere)
and scientific publication.

2004 Edward S. Deevey Award
Edward S. Deevey, a founder of modern paleoecology, was a dedicated student advisor who mentored many investigators active in the field today. To honor his memory and encourage high-quality research by graduate students, the Paleoecology Section presents an award to the student or recent graduate making the best oral or poster presentation in paleoecology at the ESA Annual Meeting. Jason McLachlan, a recent Ph.D recipient from the Biology Department at Duke University, won the 2004 Deevey Award for his talk titled The importance of small populations in the postglacial dynamics of eastern forests. Dr. McLachlans presentation, which he conducted with coauthors James S. Clark and Paul S. Manos, used patterns of genetic variation in modern tree populations and fossil pollen data to reconstruct patterns of postglacial migration in eastern North America. |
The presentation synthesized results recently published in Forest Ecology and Management and currently in review in Ecology. The judges committee was particularly impressed with his innovative methodology and the significance of his work to future paleoecological research. Dr. McLachlan has a B.A. in Geography from Columbia University and an M.S. in Forest Ecology from the University of Washington. This fall, he is starting a postdoctoral appointment at the Harvard Forest, where he will continue to integrate fossil pollen data with molecular markers and statistical models to understand the historical population dynamics of forests. Philip Higuera received honorable mention for his presentation titled When does a charcoal peak represent a fire? Insights from a simple statistical model. Mr. Higuera is a graduate student in the College of Forest Resources at the University of Washington. Coauthors Daniel G. Gavin and Matthew E. Peters assisted Mr. Higuera with this research. The Paleoecology Section thanks students who competed for this years Deevey Award and encourages others to participate in the 2005 competition, to be held at the Annual Meeting in Montréal, Canada. The Section also appreciates the efforts of the 2004 Deevey Award Selection Committee: Jason Lynch (Chair), Lisa Carlson, Allen Solomon, Bob Booth, Don Falk, and Bryan Shuman.

Territory quality is a multifaceted concept, incorporating various components ultimately related to fitness potential, such as predation risk and availability of essential resources like food, suitable foraging habitats, and breeding sites. Gathering information on all such components may be a difficult task, especially for inexperienced individuals choosing a territory for the first time. The wrong choice may have severe consequences, including death. Evidence is increasing that individuals may employ comprehensive indirect cues to assess habitat and territory quality, including risk of predation. We examined the decision rules employed by a medium-sized opportunistic raptor, the Black Kite (Milvus migrans), to establish territories. Kites were studied for 12 years in various study plots scattered through the Alps. There, the diet is dominated by fish and Black Kites mainly breed in loose colonies on cliffs facing large lakes, their optimal habitat for foraging. Such habitat is also favored by Eagle Owls (Bubo bubo), which may prey on kite adults and nestlings, especially when the two species nest within one to two kilometers of each other. We found that Black Kites employed a mixture of direct and indirect cues to establish new territories. Independently of phylopatry and coloniality, new territories were typically near to already occupied ones that had higher than average breeding performance in the previous year, implying that the owners of the new territory watched their conspecifics in previous years to collect information on which to base their future decisions. Such exploitation of public information affected nest spacing and population trend. On one hand, as colonies grew, the distribution of nests within them became more clumped, while on the other hand, higher colony and population-level productivity in one year were followed by higher recruitment of new breeders in the following year. Finally, the establishment of new territories near conspecifics was not a peaceful process. There was much fighting between the new neighbors and a breeding cost for the previous residents, suggesting that conspecific cuing may be a form of information parasitism, at least in our study system. Look for the article by F. Sergio and V. Penteriani, Public information and territory establishment in a loosely colonial raptor, to be published in Ecology Volume 86, February 2005. |
| Enhancement of soil nitrogen (N) cycling by grazing has
been observed in many grassland ecosystems. However, whether grazing
affects the activity only of the key microbial functional groups driving
soil N dynamics, or also affects the size (cell number) and/or composition
of these groups remains largely unknown. We studied the enzyme activity,
size, and composition of five soil microbial communities (total microbial
and total bacterial communities, and three functional groups driving
N dynamics: nitrifiers, denitrifiers, and free N2 fixers) in grassland
sites experiencing contrasting sheep grazing regimes (one light grazing
[LG] site and one intensive grazing [IG] site) at two topographical
locations. Greater enzyme activities, particularly for nitrification,
were observed in IG than in LG sites at both topographical locations.
The numbers of heterotrophs, nitrifiers, and denitrifiers were higher
in IG than LG sites at both topographical locations. Phospholipid and
nucleic acid analyses showed that the composition of all the communities,
except nitrate reducers, differed between IG and LG sites at both locations.
For each community, changes in activity were correlated to changes in
the occurrence of a few individual PLFAs (phospholipid fatty acids)
or DNA fragments. Our results thus indicate that grazing enhances the
activity of soil microbial communities, but also concurrently induces
changes in the size and composition/structure of these communities on
the sites studied.
Look for the article by A. K. Patra et al., Effects of grazing
on microbal functional, groups involved in soil N dynamics,
in the February 2005 issue of Ecological Monographs 75(1).

Contributions
The problem with the messages of plantherbivore interactions in ecology textbooksPlantherbivore interaction is one of two parts of the first
trophic transfer of energy and nutrients between organisms in ecosystems
(the other part being the dead plantdetritivore path). Despite
its importance in understanding life on Earth, students in general
seem to have limited knowledge of what we have learned about plantherbivore
interaction (Stamp 2004). That can translate into the public not having
adequate background to evaluate government policy, for instance, relative
to effects of global warming on agriculture and forestry, genetic
modification of crops, insect pest and weed control, range management,
or zoonotic diseases reflecting human disturbance of plantherbivore
systems (e.g., Lyme disease). Historical perspective Given its era, each text had information, presentation, and features to recommend it. In the 1970s, there was an average of 0.4% of the text devoted to plantherbivore interactions and plantherbivore population dynamics, and another 0.2% on plant defense. The emphasis was on predatorprey interactions, especially conspicuous patterns of consumption of and damage to plants. In the 1980s, there was an average of 0.6% on plantherbivore interactions and dynamics, with another 0.6% on plant defense. The descriptions tended toward the arms-race view of plantherbivore interactions. In the 1990s, there was an average of 0.7% on plantherbivore interactions and dynamics, with another 0.5% on plant defense, but the messages tended to be diluted by the emphasis on specific examples. In the 2000s, there was an average of 0.7% on plantherbivore interactions and dynamics, with another 0.8% on plant defense, but the messages still werent coming across as clearly as needed. Messages in recent ecology textbooks Below are some key messages of plantherbivore interactions
and how they are (or are not) presented in ecology textbooks published
in the last 10 years. |
