Understanding animal movement can be important for monitoring design and management decision making. Ungulate movement in the landscape is often driven by the local environment. Most, if not all, ungulate species select for food resources and safety, and their movement is facilitated by landscape structures. However, species do not necessarily respond to their environment in the same way. To quantify variability in species responses to their environment, we leveraged a multi-ungulate system in Northwest Montana. This area is heavily forested but heterogenous as areas of it are subjected to yearly wildfires, commercial logging, hunting, and dissected by roadways.

We collared 13 elk, Cervus canadensis, 25 white-tailed deer, Odocoileus virginianus, and 25 mule deer, O. hemionus during 2024-2025. We analyzed GPS fixes (3-hour intervals) using step selection functions. We built single-species models, tested for the effect of habitat features, and compared ungulate habitat selection with the same spatial and temporal extent and resolutions. This comparative study sheds light on similarities, but also differences in ungulate habitat selection. Results may also inform design of camera-trap based monitoring protocols.

Wildlife populations are exposed to diverse parasite communities, where co-infection is the rule rather than the exception. Understanding the mechanistic effects of co-infection on disease dynamics requires moving beyond the traditional focus on single pathogen - single host systems. We use infection of Sin Nombre hantavirus (SNV) in wild deer mice (Peromyscus maniculatus) as a model system to identify potential mechanistic effects of co-infection on disease dynamics of SNV in its reservoir host. We trapped and removed wild deer mice (n = 1,065) from six sites across western Montana from 2023-2025 and tested individual SNV serostatus (n = 78 seropositive of 1,054 tested to date) and adult helminth infection via gastrointestinal dissection (n = 181 infected of 318 dissected to date). We used joint species occupancy (infection probability) models with symmetric interactions to estimate parameters of non-independent infection (presence/absence) of co-infecting parasites. This approach allows us to describe infection probability of each parasite species conditional on infection with other parasites and is preferable to linear models which assume an effect of one species on another but not vice versa. We compared models to determine whether Trichuris stansburyi, Calodium hepaticum (tissue-invasive helminths), and SNV interact in individual mice and to estimate effects of host characteristics, sex and body length, on independent infection and on interactions. The top model incorporated (1) non-independent interactions between parasite species, (2) a strong positive effect of body length on each infection (likely because older individuals have more time to become infected) and (3) a positive effect of sex (being male) on interactions. Predicted SNV infection probability was significantly higher in mice (especially males) that were co-infected with C. hepaticum. These results confirm that co-infections in this system are not independent and are impacted by host characteristics, emphasizing the importance of integrating co-infection into investigations disease dynamics.

Uncertainties about population dynamics may hamper the ability of state agencies and commissions to make informed wildlife management decisions. In hunting district 121, Montana, bull elk harvest has declined since 2012. Minimum counts suggest populations have been stable; however, it’s unknown if these counts reflect actual abundance and there are no vital rate data available for the region. Due to these uncertainties, Montana Fish, Wildlife & Parks developed an adaptive management project to address data gaps and uncertainties. From 2022-2025, we GPS collared 124 adult females, 18 adult males, and 185 neonate or 6-month-old calves. Across all years, the average adult pregnancy rate was 84% (n = 122). Based on initial elk survival estimates through 2024, adult female survival was 0.891 (95% CI = 0.832 – 0.954) and adult male survival was 0.571 (95% CI = 0.301 – 1.0) with leading causes of mortality for all adults including harvest (n = 5/15) and mountain lions (n = 3/15). Calf survival was 0.537 (95% CI = 0.377 - 0.764) with leading causes of mortality including mountain lions (n = 10/27) and black bears (n = 6/27). We combined these population estimates with information about carnivores, habitat, and harvest into an IPM and initial results indicate the population is stable but has high bull harvest. Ultimately, this IPM will provide the analytical tool needed to inform management decisions and select management prescriptions to achieve elk population size objectives in an adaptive management framework.

Family Support, Gender Affirmation, and More: Community Resilience Factors for Trans and Gender Diverse Individuals

10:00 AM - 10:50 AM

Transgender and gender diverse (TGD) individuals face significant mental health disparities. Minority stress research has identified key contributors to these disparities and, more recently, begun to examine factors promoting resilience. While family support and gender-affirming care well-established protective factors, but few studies have evaluated additional potential sources of resilience. During a time of increased minority stress for TGD individuals, identifying protective factors and pathways to resilience are especially important.

278 TGD adults completed an online survey and answered questions about the following community-level resilience factors: perceived support from significant others, family, and friends;  LGBT community connectedness; medical and legal gender affirmation; engagement in collective action; media representation currently and in childhood; and identification as a positive role model. Five stepwise regressions examined the associations between these factors and depression, anxiety, alcohol use, psychological distress, and psychological wellbeing.

Resilience factors were significantly predictive of all outcomes except alcohol use. Perceived family support emerged as a significant predictor of lower depression, anxiety and psychological distress, as well as greater psychological wellbeing. Higher levels of gender affirmation were associated with less anxiety and general distress. In addition, greater perceived significant other support and media representation in childhood were significant predictors of lower depression and anxiety, respectively. Psychological wellbeing was uniquely positively associated with perceived friend support and identification as a positive role model.

Results reaffirm the particular importance of family support and gender-affirming care TGD adults. However, the presence of significant other and friend support, media representation, and identification as a positive role model as predictors also highlights that research on TGD health disparities should continue to examine multiple forms of resilience. Differences in predictors between psychological wellbeing and negative outcomes underscore the value of strength-based approaches through investigating positive outcomes.

Lovecraftian Hybrids and Transgender Embodiment

Mari K. Newman

10:00 AM - 10:50 AM

     While much of Howard Phillips Lovecraft’s oeuvre has been analyzed by queer theorists for homosexual metaphors within Lovecraft’s monsters, less argued is the subject of his hybrids mirroring transgender embodiment. I posit the rise of transgender identities in the Western mainstream and access to breakthrough gender-affirming care in the United States during Lovecraft’s life lend to a reading of his hybrids as embodying gender queerness. The proposed research is a literature review which draws upon interdisciplinary texts ranging from scholars in the social sciences—such as sociology and anthropology—to the hard sciences such as ecology and health sciences.

In this paper, I examine several of Lovecraft’s stories, including “The Hound,” “The Call of Cthulhu,” “The Shadow over Innsmouth,” and the novella At the Mountains of Madness. These texts showcase Lovecraft’s hybrid monsters, such as the titular Cthulhu, who takes the form of “an octopus, a dragon, and a human caricature” as a representation of transgender embodiment due to the monster’s queered hybridity. Additionally, I contribute that the “cosmic horror” felt by Lovecraft’s narrators stems from internal and externalized transphobic norms. By analyzing the historical context of H.P. Lovecraft’s stories and his life, his written works reveal a hybrid amalgamation of appendages, slimy abjection, and queer transference by cisnormative imaginations. Utilizing theorists such as Julia Kristeva, J. Halberstram, and Judith Butler, I argue Lovecraft’s monsters embody the horrors of the Old Weird fiction genre by showing the public the possibility of a new, weird way of reproducing that threatened to choke out the patriarchal standard of reproduction.

There is No Intonation Rule for Yes-No Questions in Blackfoot

Chance Lockwood, University of Montana, Missoula

10:00 AM - 10:50 AM

Cross-linguistically, the intonation of questions differs from the intonation of their declarative counterparts. For example, the intonation of an English question is normally raised at the end of the sentence, while the intonation of a statement is not. Also, in some languages the range of pitch is greater in questions than in statements. However, to my knowledge there are no intonation studies on Blackfoot that focus on questions, only on other elements of intonation, such as pitch movement, stress predictability, and rhythm. Using Praat, a program designed for acoustic speech analysis, I examined the intonation patterns of 19 statement-question pairs produced by a native speaker of Blackfoot. My research reports that sentence-final pitch raising does not occur in Blackfoot yes-no questions. I also examined the pitch range differences within each pair, and the results showed no significant differences between yes-no questions and their respective statements in Blackfoot. These findings suggest that speakers of Blackfoot do not use intonation to differentiate between questions and statements. This study has the following significances. (i) It contributes to the typological study of intonation in questions cross-linguistically. (ii) It also contributes to the descriptive study of pitch movement in Blackfoot by describing Blackfoot yes-no questions in terms of intonation. (iii) This study assists Blackfoot pedagogy with information on authentic pronunciation of yes-no question sentences: It informs language teachers and learners about how Blackfoot yes-no questions are pronounced in terms of intonation, specifically focusing on the absence of final pitch raising.
