“…Understanding where moose consume Z. arboreus and other intermediate hosts is important for designing effective interventions such as altered timber management practices that change gastropod distributions and assemblages (Severud et al 2023). Based on previous gastropod surveys in our study area (Lankester and Peterson 1996; Cyr et al 2014; Severud et al 2023), Z. arboreus is less common than other known P. tenuis hosts (e.g., Discus cronkhitei , Derocerus laeve , and S. ovalis ) and rarely climbs vegetation (McCoy and Nudds 1997; Hawkins et al 1998; Nekola 2003), making it less likely to be accidentally consumed by moose that are browsing live foliage. Moose may encounter Z. arboreus in forest types that contain paper birch ( Betula papyrifera ), because moose and deer spend significant time there, and those forest types support high Z. arboreus densities (Kearney and Gilbert 1978).…”

“…Although Punctum minutissimum has not been screened extensively for its ability to host P. tenuis (Lankester and Anderson 1968; Platt 1989; Cyr et al 2014), it shares the ground-dwelling trait that may make Z. arboreus a common host (Pilsbry 1939). Punctum minutissimum and moose both have documented preferences for recently logged or disturbed areas (Kralka 1986; Timmermann and McNicol 1988; Severud et al 2023), so further research is warranted to better understand the P. tenuis host potential of Punctum minutissimum .…”

“…Lankester and Peterson (1996) hypothesized that deer fawns consume approximately 50 gastropods a day in autumn, yet we only detected five gastropod consumption events in moose and none in deer over 265 samples. In addition, we did not detect the gastropod species most common in our study area based on timed searches ( Arion spp., 68% of all species; Severud et al 2023). Unlike previous studies, our study was specifically designed to observe consumption events.…”

“…The reference database (Ratnasingham and Hebert 2007) contained all Gastropoda COI sequences deposited in the Barcode of Life Database (BOLD) as of 10 November 2021. This database included at least one species representative of 83% of the surveyed gastropod species in our study area (Lankester and Peterson 1996; Cyr et al 2014; Severud et al 2023) and at least one genus representative of the remaining 17%. We also tested a 90% similarity threshold between the reference and the query to minimize the chance of excluding species that only had a genus representative in the database.…”

“…However, some gastropod host species may be yet to be investigated, because methods used in those studies underestimate both gastropod density and diversity (Hawkins et al 1998). Furthermore, knowing whether species detected as P. tenuis hosts in previous studies are actually consumed by moose would be a key step toward designing interventions that reduce contact between moose and gastropod hosts (Severud et al 2023).…”

Our understanding of wildlife multihost pathogen transmission systems is often incomplete due to the difficulty of observing contact between hosts. Understanding these interactions can be critical for preventing disease-induced wildlife declines. The proliferation of high-throughput sequencing technologies provides new opportunities to better explore these cryptic interactions. Parelaphostrongylus tenuis, a multihost parasite, is a leading cause of death in some moose (Alces alces) populations threatened by local extinction in the midwestern and northeastern US and southeastern Canada. Moose contract P. tenuis by consuming infected gastropod intermediate hosts, but little is known about which gastropod species moose consume. To gain more insight, we used a genetic metabarcoding approach on 258 georeferenced and temporally stratified moose fecal samples collected May–October 2017–20 from a declining population in the north-central US. We detected moose consumption of three species of gastropods across five positive samples. Two of these (Punctum minutissimum and Helisoma sp.) have been minimally investigated for the ability to host P. tenuis, while one (Zonitoides arboreus) is a well-documented host. Moose consumption of gastropods documented herein occurred in June and September. Our findings prove that moose consume gastropod species known to become infected by P. tenuis and demonstrate that fecal metabarcoding can provide novel insight on interactions between hosts of a multispecies pathogen transmission system. After determining and improving test sensitivity, these methods may also be extended to document important interactions in other multihost disease systems.

Moose (Alces alces; mooz [singular], moozoog [plural] in Anishinaabemowin, Ojibwe language) are an important species to many Indigenous rights‐holders and stakeholders throughout their circumpolar range. Management of moose can often lead to conflict when various perspectives of Indigenous nations are not recognized or appreciated. During the 55th North American Moose Conference and Workshop held in Grand Portage, Minnesota, USA, we held a workshop with 145 participants centered around co‐stewardship of moose among various Indigenous nations, federal, state, and provincial governments, academia, and non‐governmental agencies. Using a facilitator, the participants identified opportunities and challenges surrounding issues related to moose management. Participants then further identified priority improvements and action steps for co‐stewardship. Six core principles of Indigenous co‐stewardship were developed: 1) recognition of Indigenous Sovereignty, which specifies that co‐stewardship must begin with a recognition of the sovereignty of Indigenous nations and their inherent rights to manage, conserve, and preserve natural and cultural resources within their ancestral lands; 2) shared responsibility, where co‐stewardship is a shared responsibility between Indigenous nations, federal governments, and state governments; 3) cultural and ecological respect, which stipulates that co‐stewardship should honor the cultural significance of moose to Indigenous nations and recognize the ecological importance of moose within the broader ecosystem; 4) inclusive decision‐making, which details that co‐stewardship requires inclusive and equitable decision‐making processes that involve meaningful consultation and consent from Indigenous nations; 5) resource sharing and capacity building, where co‐stewardship involves the sharing of resources and knowledge between Indigenous and non‐Indigenous partners; and 6) adaptive management and sustainability, specifying that co‐stewardship should embrace adaptive management principles, where management strategies are continuously evaluated, adjusted, and improved based on new information and changing conditions. Some of the key takeaways from the workshop included that it will be essential to integrate Indigenous ways of knowing into an equitable and inclusive management system, there are existing models of co‐stewardship that can be built upon, it is critical to build trust among all key stakeholders and rights‐holders, and it will be important to establish formal and informal collaborative systems among all partners to support co‐stewardship at all levels. We discuss a study and synthesis on Indigenous co‐stewardship of moose and offer a synopsis and recommendations to advance restoration of moose in North America.
