Biology’s drones:
Undermined by fear
IN HIS NEWS & ANALYSIS STORY “Drones
flying high as new tool for field biologists”
(2 May, p. 459), R. Schiffman reports the
use of drone technology for conservation
law enforcement to combat the surge in
elephant and rhino poaching. This rush
to deploy such technologies is based on
compelling ideas, partly influenced by nar-
ratives that describe the current situation
in terms of a war between poachers and
conservation staff.
The reality of conservation is much
more complicated, as many people live in
or around protected areas and depend on
them for fuel wood, medicines, and food (1).
Seen from the ground and through their
eyes, drones may be perceived as sinister
technologies of surveillance or be associ-
ated with warfare and civilian casualties.
Such negative perceptions could be seen as
a return to fortress conservation, reducing
support for protected areas and undermin-
ing the relationships on which successful
research and conservation projects are built.
Given the rise in poaching activities, one
could argue these negative risks are part of
a necessary trade-off. However, there are
two reasons for doubting the value of such
a compromise. First, the long-term cost-
effectiveness of drones in deterring
poaching remains untested. Second,
drone data will only be effective if fed into
well-functioning management and legal
systems, which are lacking in many coun-
tries. Thus, funding for enforcement may
be better spent on increasing park staff
numbers, resources, and training; develop-
ing intelligence networks to catch poachers
in the act and identify corrupt officials;
and strengthening the judicial system (2).

Biology’s drones:
New and improved
IN THE NEWS & ANALYSIS STORY “Drones
flying high as new tool for field biologists”
(2 May, p. 459), R. Schiffman presents a
new useful application of unmanned aerial
vehicles (UAVs) in the field of monitoring
wildlife, but the drones still have some
limitations. The quadrotor UAVs that they
use to drive elephants out of the woods or
monitor tigers can only work for a maxi-
mum of 20 minutes and have to fly back to
the ground station to recharge. In this case,
the supervision time that biologists could
get from the UAVs will be quite little.
To provide longer working time and
finish tasks in different flight conditions,
scientists and engineers are working
to improve the design of UAVs. At the
University of Pennsylvania, researchers
have added a mechanical claw at the bot-
tom of a quadricopter (1) to allow the UAV
to catch a target. At the University of Utah
(2) and Tsinghua University, UAVs can land
in hazardous terrain or even tree branches
thanks to their biomimetic design.
Such improvements that merge bionics
and robotics together will let UAVs fly
inside caves, claw into tunnels, or perch on
tress. Biologists or scientists in other fields
will then be able to track their targets
more effectively.

Investigative bioethics
IN HIS PLENARY ADDRESS at the 2009
annual meeting of the American Society
for Bioethics and Humanities, Carl Elliott
challenged attendees to take up the role
of the investigative reporter. Many past
research scandals, he noted, were not
brought to light by traditional scholar-
ship of professional bioethicists. Rather,
they were discovered through the diligent
efforts of investigative journalists who
followed evidence wherever it led and
then shared their findings in a way that
grabbed the attention of the American
public. As newspapers continue to
downsize or go bankrupt, Elliott argued,
it should be the goal of the bioethics com-
munity to fill that role in the realms of
clinical research and medicine. J. Couzin-
Frankel’s Feature “A lonely crusade” (23
May, p. 793) details Elliott’s efforts to live
by his own words.
I commend Couzin-Frankel for helping
to shine a light into those “odd, interest-
ing corners” of psychiatric drug trials of
the kind Elliott is investigating. Serious
questions remain unsettled about such
research, not just the CAFE study in which
Dan Markingson, who committed suicide
10 years ago, was a participant: questions
of conflicts of interest, the distinctions
between research and therapy, standards
for assessing competency to provide
informed consent, and the adequacy of the

regulatory framework under which this
research takes place. As bioethics is still
trying to sort out its features as a disci-
pline, I hope it heeds the example of Elliott
and his allies. Otherwise, these issues will
not receive the critical examination they
warrant and Markingson’s story will be,
sadly, one of many.

Deep-sea protection:
Coordinate efforts
THE PLIGHT OF deep-sea ecosystems in
areas beyond national jurisdiction (ABNJ)
has been persistently overlooked. As a
consequence, they remain very poorly pro-
tected despite calls for action dating back
more than a decade. In 2002, the United
Nations General Assembly called upon
intergovernmental organizations including
the Food and Agriculture Organization, the
Convention on Biological Diversity, and the
UN Secretariat itself to urgently consider
means to reduce risks to the biodiversity
of seamounts and other vulnerable deep-
sea habitats within the framework of the
United Nations Convention on the Law of
the Sea (UNCLOS) (1). Since then, various
international and regional bodies such as
the International Maritime Organization
(IMO), the International Seabed Authority
(ISA), and Regional Fisheries Management
Organizations (RFMOs) began exploring
measures and regulations pertaining to
shipment; oil, gas, and mineral extraction;
and fishing and trawling (2). However,
these efforts have been slow to materialize,
in addition to lacking effective coordina-
tion. Therefore, we praise the call by K. J.
Mengerink et al. (“A call for deep-ocean
stewardship,” Policy Forum, 16 May, p. 696)
for the UN General Assembly to consider
the resolution of governance issues of the
ABNJ as a priority in its 2015 deliberations.
States agreed during the Rio+20
Conference to address the issue of
conservation and sustainable use of
marine biological diversity of ABNJ (3).
This includes a call for the UN General
Assembly to consider the wisdom of
establishing an international instrument
under the UNCLOS to overcome the lack
of coordination between different inter-
governmental organizations and their
respective mandates. Such an instrument
could become more effective in promot-
ing comprehensive oceans governance
reform within the framework of an already
established convention, together with
fostering complementarity among relevant
organizations.
We also recognize the paucity of fund-
ing to generate baseline, protection, and
mitigation actions. At the same time, we
question whether the multiplication of
funding mechanisms would be practical or
even desirable. We believe that the finance
question should complement the resolu-
tion of the key governance issues, while
building on existing platforms.
