Potential Tool for Swift Fox (Vulpes velox) Conservation: Individuality of
Long-Range Barking Sequences. Journal of Mammalogy:84(4),1417-1427.<br>
ABSTRACT: Vocal individuality has been found in a number canid
species. This natural variation can have applications in several aspects of
species conservation, from behavioral studies to estimating population
density or abundance. The swift fox (Vulpes velox) is a North American
canid listed as endangered in Canada and extirpated, endangered, or
threatened in parts of the United States. The barking sequence is a
long-range vocalization in the species' vocal repertoire. It consists of a
series of barks and is most common during the mating season. We analyzed
barking sequences recorded in a standardized context from 20 captive
individuals (3 females and 17 males) housed in large, single-pair
enclosures at a swift fox breeding facility. Using a discriminant function
analysis with 7 temporal and spectral variables measured on barking
sequences, we were able to correctly classify 99% of sequences to the
correct individual. The most important discriminating variable was the mean
spacing of barks in a barking sequence. Potential applications of such
vocal individuality are discussed.<br>

Calls
of Pteronotus quadridens (Chiropters: Mormoopidae) in Cuba. Journal of
Mammalogy:84(4),1428-1436.<br>
ABSTRACT: Echolocation calls were recorded from Pteronotus
quadridens flying in the field and in an enclosed space. In the field,
search calls contained 1 or 2 harmonics. Patterns of call design show a
segment of quasi-constant frequency (QCF--2nd-harmonic at 81-84 kHz),
followed by a downward frequency-modulated (FM) component. The 2nd harmonic
was always more intense than the 1st. Search, approach, and terminal phases
of calls were described during hunting sequences of P. quadridens. The
transition between call phases was characterized by monotonic variations in
some acoustic parameters, including a decrease in call duration and an
increase in repetition rate, bandwidth, and slope of the FM component. We
also analyzed calls emitted by bats flying in confined spaces that
consistently contained 3 harmonics, of which the 2nd harmonic contained the
greatest energy. The values of call duration were shorter and bandwidth was
higher than values characterizing calls emitted during the search phase in
the field.<br>

Trends, Challenges, and Future Directions. Journal of Mammalogy:84(4),

ABSTRACT: Papers in this Special Feature were presented at a
symposium on the social biology of rodents that was held in June 2001 at
the 81st Annual Meeting of the American Society of Mammalogists. Our
decision to host a symposium on this topic resulted from our realization
that although rodents have played a vital role in research on social
behavior, no recent summaries of the social biology of these animals were
available. Given the number of biological disciplines, research strategies,
and species that are relevant to this topic, a comprehensive review of
rodent social biology was not possible. Instead, in structuring the
symposium, we chose to focus on a subset of behavioral issues for which
studies of rodents currently are providing exciting new insights. Topics
selected for inclusion--communication, kin recognition, philopatry, and
sociality--are timely and are of considerable interest to biologists
studying a wide array of animal taxa. Thus, papers presented in the
symposium reflect recent advances not only in our knowledge of rodent
social biology but also in our conceptual understanding of animal social
behavior.<br>

Rodents. Journal of Mammalogy:84(4), 1163-1181.<br>
ABSTRACT: Significant advances have been made in understanding kin
recognition as it pertains to nepotism (preferential treatment of kin) and
mate choice (optimization of inbreeding and outbreeding). Yet complementary
knowledge about how animals discriminate conspecifics on the basis of
genetic relatedness remains unclear for most species. Because of the
diversity of their scent sources and highly developed olfactory systems,
rodents present a unique opportunity for examining chemical communication
and kin recognition as a function of sociality. I review general processes
of kin recognition and summarize mechanisms of recognition used by rodents.
As a case study, I also examine recognition systems of ground squirrels,
relating odor production and perception to differences in patterns of
nepotism. Belding's ground squirrels (Spermophilus beldingi) produce >= 2
odors (from oral and dorsal glands) that correlate with relatedness (kin
labels), and they are able to use these odors to make precise
discriminations among their unfamiliar relatives. Thus, S. beldingi can
recognize their distant female kin and male kin, even though these kin are
not treated nepotistically (e.g., through cooperative territory defense or
alarm call production). Furthermore, S. beldingi use these kin labels and
recognition abilities to interact differentially with conspecifics as a
function of relatedness. In ground squirrels and in other rodents,
components of the kin recognition process (production of recognition cues,
discrimination of these cues, and differential treatment of conspecifics)
have evolved differentially among even closely related species. Kin
recognition abilities in the absence of nepotism might reflect selection
for inbreeding avoidance mechanisms, in addition to sex-biased natal
dispersal. Together, data and the review demonstrate that recognition
abilities cannot be predicted on the basis of sociality alone and suggest
that comparative analyses, by multiple assays of discrimination, might be
necessary to understand variation in the function of kin recognition within
and across species.<br>

Forgotten Rodents, Neglected Questions. Journal of
Mammalogy:84(4),1212-1227.<br>
ABSTRACT: I identify 4 topics for future research. 1) Our knowledge
of rodents from the developing world is limited, yet recent evidence
suggests that many species are highly social. I concentrate on South
American rodents to demonstrate the wealth of information available when we
study these taxa and incorporate the findings into our current paradigms of
social evolution. 2) Relatively little is known about proximate mechanisms
that govern social systems. Research on the neuroendocrine basis of
pair-bond formation and paternal care has provided valuable insights, but
many questions remain. 3) Mounting evidence indicates that, in addition to
genetics, social environment can play a major role in behavioral and
physiological development. Studies on effects of early social environment
would contribute to our understanding of ontogeny of individual differences
in social species. 4) Recent evidence suggests a significant geographic
variation in social characteristics of some rodent species. The extent and
ecological correlates of such intraspecific variation merit further
investigation.<br>
