3 International Conference on Rodent Biology and Management 3rd International Conference on Rodent Biology and Management Hanoi, Vietnam September 2006 rd 3 International Conference on Rodent Biology and Management 28 August - 1 September, 2006 Hanoi, Vietnam 28 August 2006 Prof. Nguyen Van Tuat National Institute of Plant Protection Chem Tu Liem Hanoi VIETNAM Dear Conference Participants On behalf of the Conference Organising Committee, I have great pleasure in welcoming you to 3rd International Conference on Rodent Biology and Management (3rd ICRBM) here at the Thang Loi Hotel, Hanoi, Vietnam. Following the success of both the 1st and 2nd Conferences held in Beijing in 1998 and Canberra in 2003, the objective of the 3rd Conference is to once again to bring together scientists and practitioners who are interested in all aspects of rodent biology and their management. Currently we are expecting up to 150 rodent biologists from around the globe to gather for 5 days to exchange research and ideas. The Committee trusts that you will make the most of this excellent opportunity to meet others working on many different aspects of rodent biology and management. We hope that many new friendships, learnings and collaborations will develop during the next few days. We look forward to meeting you during the Conference and welcome your contribution and participation. Please enjoy the hospitality and culture of Hanoi and Vietnam. Yours sincerely Prof. Nguyen Van Tuat On behalf of the 3rd ICRBM Conference Organising Committee List of Sponsors The Conference Organising Committee wishes to gratefully acknowledge the support of the following organisations National Institute for Plant Protection (NIPP), Hanoi, Vietnam Institute of Zoology (IOZ), Chinese Academy of Sciences, Beijing, China CSIRO, Canberra, Australia Australian Agency for International Development (AusAID), Canberra, Australia Australian Centre for International Agricutlural Research (ACIAR) The Technical Centre for Agricultural and Rural Cooperation (CTA), The Netherlands Local Organising Committee Dr. Nguyen Hong Son National Institute of Plant Protection (NIPP) Dr. Nguyen Phu Tuan Chem - Tuliem- Hanoi, VIETNAM National Institute of Plant Protection Chem Tu Liem Mrs. Pham Thi Hong Hanh Hanoi, VIETNAM National Institute of Plant Protection Chem Tu Liem Hanoi, VIETNAM - 4 - 3rd ICRBM Organising Committee Honorary Chairman Prof. Charles Krebs Dept of Zoology University of British Colombia Vancouver B.C.

Box 321 Khartoum, Sudan Non-geographic morphometric variation particularly at the level of sexual dimorphism and age variation has been extensively documented in many organisms including rodents, and is useful for establishing whether to analyse sexes separately or together and for selecting adult specimens to consider for subsequent data recording and analysis. However, such studies have largely been based on linear measurement-based traditional morphometric analyses that mainly focus on the partitioning of overall size- rather than shape-related morphological variation. Nevertheless, recent advances in unit-free, landmark/outline-based geometric morphometric analyses offer a new tool to assess shape-related morphological variation. In the present study, we used geometric morphometric analysis to comparatively evaluate non-geographic variation in two geographically disparate murid rodent species, Aethmoys ineptus from South Africa and Arvicanthis niloticus from Sudan , the results of which are also compared with previously published results based on traditional morphometric data. Our results show that while the results of the traditional morphometric analyses of both species were congruent, they were not sensitive enough to detect some signals of non-geographic morphological variation.

We developed the database of individual variants of B chromosome systems in A. peninsulae. In Siberian populations all animals had Bs. The karyotypes of the studied animals contain from 1 to 30 Bs differing in size and morphology. Analysis of B chromosome systems in 598 individuals from different localities of the range shows the presence of 286 variants of Bs combinations in these animals. Unique sets of B morphotypes make up most of these variants (64.7 ± 1.3%), probably suggesting that individual Bs systems normally result from stochastic processes in the populations. The proportion of animals with a large number of Bs gradually decreases, probably due to increased complexities in the inheritance of large numbers of Bs. A. peninsulae is thus proposed as a good model for studying the origin and evolution of extra elements in the karyotype.

Kartavtseva Institute of Biology and Soil Science, Russian Academy of Sciences, Far East Division, Vladivostok, Russia *email: [email protected] Received September 25, 2008 Abstract—A karyotype analysis of the Apodemus peninsulae (n = 355) from 41 trapping points from the Rus sian Far East has allowed us to identify B chromosomes in 87.9% of the animals, 61.7% of which are mosaics. Different levels of variability in the B chromosome numbers have been studied, including both the inter and intrapopulational, as well as intraindividual variability (mosaicism). It was found that the frequencies of the occurrence of individuals with B chromosomes and mosaicism between different population samples were not constant. The range of the modal B chromosome number variability and variation of the xB index (zero to four; on average, the xB amounted to 1.67) were studied for the first time in different samples and popula tions of this species. Individuals with the predominant numbers of B chromosome (as a rule, zero to two) were revealed in both groups of animals (with stable and mosaic karyotypes), but the frequency was different in geographical regions. The spectra of B chromosome variability were wider in mosaics (zero to seven) com pared to animals with stable karyotypes (zero to four).

For the first time the unique population of mouse Apodemus peninsulae which had numerous micro- B-chromosomes (12-30), was found in Krasnoyark region. The mouse population inhabits a site at the left bank of the Yenisey river in 85 km downstream of the town of Zheleznogorsk where the Mining and Chemical Combine with chemonuclear complex is situated. The population of A. peninsulae from Gorny Altai showed threefold increase in number of B-chromosomes, from 2,3 to 7,1, during 28-year (1980-2008) studied period. The region of Gornyi Altai is the area where details of rockets launched from the Baikonur cosmodrome fall down. It was shown that the frequency of B-chromosomes of the Siberian spruce Picea obovata is higher in urban plantations (Krasnoyarsk city) than in its native populations.

Factors affecting body temperature (Tb) fluctuations in winter were examined in Korean field mice Apodemus peninsulae. Animals were maintained under the following three conditions to mimic autumn followed by winter, plus two modes of behaviour, solitary and grouped, in winter: 1) short day (8 Light:16 Dark) at 25 ± 2°C and solitary, for 12 weeks towards the end of which their Tb was recorded; 2) constant darkness (DD) at 4 ± 2°C and solitary, for a week; and 3) DD at 4 ± 2°C and in groups (two or three animals in a cage), for about 10 days. Using implanted data loggers Tb was monitored in 13 mice that were exposed to these three conditions in sequence. When the animals’ body temperature was below 30°C, it was assumed that they were torpid according to the bimodal pattern of minimum daily Tb. The maximum period of daily torpor was 390 min/day, and torpor was exhibited by seven of the thirteen animals exposed to conditions-2) and -3).

As the past two decades have seen huge progress in application of molecular techniques, we decided to throw a glance on new data on Bs in mammals and to review them. We listed 85 mammals with Bs that make 1.94% of karyotypically studied species. Contrary to general view, a typical B chromosome in mammals appears both as sub- or metacentric that is the same size as small chromosomes of standard complement. Both karyotypically stable and unstable species possess Bs. The presence of Bs in certain species influences the cell division, the degree of recombination, the development, a number of quantitative characteristics, the host-parasite interactions and their behaviour. There is at least some data on molecular structure of Bs recorded in nearly a quarter of species. Nevertheless, a more detailed molecular composition of Bs presently known for six mammalian species, confirms the presence of protein coding genes, and the transcriptional activity for some of them.

    The Implications of Animal Movement on Camera Detections as a Means to Monitor Density by Kate Broadley A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Ecology Department of Biological Sciences University of Alberta © Kate Broadley, 2017 ABSTRACT Camera traps are an increasingly popular tool for wildlife management. Studies that use detection rates as a simple index of relative abundance assume that movement is not density- dependent. More complex techniques such as spatially-explicit capture recapture models, occupancy models, or N-mixture models make various assumptions about animal home range size in relation to camera spacing. While some assume individual animals can visit multiple camera sites, others assume sites are independent such that no individual can be detected at more than one camera. In all these methods, variation in space use has the potential to confound population estimates and compromise current applications of camera trapping as a monitoring tool. To assess this problem, I quantified how movement rate and home range size vary both between and within populations, and investigated the implications of this variation for camera trap data analysis. To quantify the relationship between space use and population density, I conducted a meta-analysis of studies reporting movement rate, home range size, or density for at least two populations of terrestrial mammals. I found that movement rate and home range size are significantly negatively correlated with density and positively correlated with each other. Using simulations of animal movement and density, I found that density-dependent movement can obscure trends in density indexed by detection rates.
