2011-12-06 14:15 Exploring benefits of interactions between vultures<br />

and famers through multi-agent modelling<br />

The vulture’s conservation relies in part on the management of their<br />

trophic resources, which is, in Europe, largely linked to farming activities<br />

and constrained by sanitary regulations. Feeding vultures can be seen as a<br />

beneficial activity both preserving these flagship species and maintaining<br />

ecological carcass elimination. We conducted an interdisciplinary<br />

framework on carcass removal by vultures in an agro pastoral context,<br />

coupling social investigations and ecological data. We developed a multiagent<br />

model in order to investigate the consequences of various local<br />

managements of carcass elimination on a population of vultures and on<br />

the benefits of such natural carcass removal. Our results underline the<br />

advantages of a carcass disposal system directly managed by farmers, called<br />

light feeding station. However, the persistence of the vulture population<br />

and the associated benefits depend on the utilization of the light feeding<br />

stations, relying on the farmers’ perceptions of vultures. We will report on<br />

the relevance of interdisciplinary approaches and multi-agent modelling <strong>for</strong><br />

applied research and management.<br />

Cheetah and wild dog are the widest ranging large carnivores in Africa.<br />

With home ranges that can exceed 1000km2, these species need massive<br />

areas <strong>for</strong> their survival. Even the best protected areas harbour populations<br />

of cheetah and wild dog less than 10% of that of lions and their survival<br />

requires a new approach to conservation. This has led to the development<br />

of the range-wide conservation process <strong>for</strong> cheetah and wild dogs,<br />

combining the species as they have similar conservation needs, and two<br />

species rather than one increases leverage. The process has the ambitious<br />

aim of securing the survival of both species across their range in Africa, by<br />

engaging support at all levels, from local communities to governments, and<br />

establishing capacity <strong>for</strong> sustainable conservation. Regional strategies have<br />

been established <strong>for</strong> eastern and southern Africa, two regional co-ordinators<br />

are in place and 9 countries have developed national conservation action<br />

plans. Declines of cheetah and wild dog have been documented from much<br />

of their range: cheetah and wild dog are currently resident in less than 15%<br />

of their historical range. Here we describe this approach, and outline the<br />

current state of conservation <strong>for</strong> both species, and achievements made.<br />

(Nestor notabilis)<br />

The Kea (Nestor notabilis) is an endemic alpine parrot of the South Island<br />

of New Zealand. After 150 years of persecution, it was fully protected in<br />

1986, but the species is still declining over its whole range. Here I present<br />

data from twelve microsatellite markers <strong>for</strong> 400 Kea from nine populations<br />

along the length of the South Island. Kea are known to have considerable<br />

dispersal capabilities and are sometimes sighted far from their alpine<br />

habitat. It is t<strong>here</strong><strong>for</strong>e expected that such a potential <strong>for</strong> gene flow would<br />

make distant populations less genetically differentiated. However, we found<br />

a significant isolation by distance (IBD) pattern. Moreover, three distinct<br />

genetic clusters were identified with little areas of genetic admixture. Our<br />

data suggest that kea population may have been separated during the last<br />

glaciations. We discuss possible causes <strong>for</strong> this unexpected population<br />

structure, including social behaviour and call differences as a barrier to<br />

dispersal and the “beech-gap” hypothesis.<br />

2011-12-08 11:30 Age matters: Adult and juvenile survival rates will<br />

respond differently to climate change<br />

Dybala, Kristen*, University of Cali<strong>for</strong>nia, Davis;<br />

Established methods exist <strong>for</strong> identifying the impacts of environmental<br />

stressors on demographic processes, yet these methods have rarely been used<br />

to project the impacts of climate change. This study examined the effects<br />

of weather and density on adult and juvenile survival rates in a population<br />

of Song Sparrows (Melospiza melodia) in central coastal Cali<strong>for</strong>nia. Thirty<br />

years of mark-recapture data (N=4,608) were analyzed to test hypothesized<br />

effects of weather on survival, and to calculate expected average adult and<br />

juvenile survival rates under several climate change scenarios. Adult survival<br />

rates were most strongly and negatively affected by summer precipitation,<br />

and secondarily by winter weather. Juvenile survival was also most sensitive<br />

to breeding season conditions, but indirectly, through the effects of the<br />

previous winter’s weather on primary and secondary productivity. Under<br />

each of the climate change scenarios, the average adult survival rate is<br />

projected to increase, while the average juvenile survival rate is projected<br />

to decrease, due to warmer winter temperatures. This approach provides<br />

insight into the age group, time of year, and mechanisms that will drive<br />

the population’s response to climate change, which may warrant further<br />

investigation, more detailed monitoring, or even management intervention.<br />

In the aftermath of intensive pre-industrial whaling in the 19th century<br />

and illegal Soviet whaling in the 20th century, no southern right whale<br />

was seen around the coast of New Zealand <strong>for</strong> over 30 years. However,<br />

a remnant population persisted in the subantarctic Auckland Islands. To<br />

describe the genetic and demographic status of the Auckland Islands right<br />

whales we collected skin biopsy samples during annual winter surveys from<br />

1995-1998 (n=354) and again from 2006-2009 (n=833). DNA profiles,<br />

including genetically identified sex, mtDNA haplotype and microsatellite<br />

genotype (13 loci) were used to identify individuals and to estimate<br />

abundance using genetic capture-recapture. The population was estimated<br />

to number 910 whales (95% CI 641, 1354) in 1998, representing
