Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region
Abstract This data release includes a list of high-priority hazardous faults and associated spatial data (regional polygons and buffered fault traces) for the Intermountain West (IMW) region of the United States. These are the top five faults or regions of concern per IMW state, based on the 2025 (v
Global Bee Interaction Data
Last modified: January 09, 2025 IntroductionThis dataset comprises all bee interactions indexed by Global Biotic Interactions (GloBI; Poelen et al. 2014). It is published quarterly by the Big Bee Project (Seltmann et al. 2021) to summarize all available knowledge about bee interactions from natural
How do humans impact yellow-bellied marmots? An integrative analysis
While many studies document specific human impacts on the behaviour and physiological responses of wildlife to humans
From the ground up: Building predictions for how climate change will affect belowground mutualisms, floral traits, and bee behavior
Climate change affects species and their interactions, resulting in novel communities and modified ecosystem processes. Through shifts in phenology and distribution, climatic change can disrupt interactions, including those between mutualists. Mutualisms influence the structure and stability of comm
Nectar addition changes pollinator behavior but not plant reproduction in pollen rewarding <i> Lupinus argenteus</i>
The addition of nectar to pollen-rewarding plants resulted in modest increases in per-flower pollinator visit duration and pollen transfer, but had no effect on reproduction because, at the place and time the experiment was conducted, plants were not pollen-limited. These results suggest that a poll
Producer-scrounger relationships in yellow-bellied marmots
Bridging animal personality with space use and resource use in a free-ranging population of an asocial ground squirrel
Butterfly foraging and the dispersal of microbes among & within flowers
Dispersal is integral to the ecology and evolution of communities. Dispersal affects bacterial communities by impacting bacterial composition and diversity in many environments. One such environment is floral organs. Flowers are nutrient-rich environments for diverse and abundant microbes. Floral mi
Are ants botanists? Ant associative learning of plant chemicals mediates foraging for carbohydrates
Abstract 1. Although associative learning is widespread across animals, its ecological importance is difficult to assess because learning is rarely studied in the field, where informative cues are juxtaposed against complex backgrounds of uninformative noise. 2. Ants rely heavily on chemical cues fo
More social female yellow-bellied marmots, <i>Marmota flaviventer</i>, have enhanced summer survival
Competition for nectar resources does not affect bee foraging tactic constancy
1. Competition alters animal foraging, including promoting the use of alternative resources. It may also impact how animals feed when they are able to handle the same food with more than one tactic. Competition likely impacts both consumers and their resources through its effects on food handling, b
Floral reward strategies, visitor behavior, and plant reproductive outcomes
Many plants that bear hidden or recessed floral nectar experience nectar robbing, the removal of nectar by a floral visitor through holes pierced in the corolla. Although robbing can reduce plant reproductive success, many studies fail to find such effects. We outline three mechanistic hypotheses th
Trap behavior of <i> Zonotrichia leucophrys oriantha </i> at different elevations in the West Elk Mountains, Colorado
High-alpine ecosystems are particularly vulnerable to climate change. Thus, many ecosystem patterns are shifting due to warming temperatures, extreme weather events, and seasonal changes. This becomes an issue for birds that breed and live in high-elevation environments, as they may not be able to c
Effects of weather and floral density on foraging activity of cavity nesting bees (<i> Osmia </i>spp.)
Thermoregulation is an important factor for bee flight which ultimately contributes to an individual’s ability to forage and produce offspring. Rising temperatures could benefit insects by increasing their efficiency in reproduction and provisioning. However, warming could negatively impact floral r
Are Marmot Alarm Class Condition Dependent?
The production and structure of animal signals may be condition dependent and may provide more than one type of information to receivers. While alarm calls are not typically viewed as condition dependent, recent studies have suggested that their structure and possibly their propensity to be emitted
Social transmission of a novel foraging trait in yellow-bellied marmots
Social transmission of novel behaviors can be an adaptive technique to rapidly and flexibly change responses to the surrounding environment. Although the dynamics of social transmission have been studied in highly social birds, primates, otters, and bats, we lack a solid understanding of the dynamic
The Effect of Predation on Ant-aphid Mutualism in <i>Ligusticum porteri</i>
Predation and mutualism take up a large part of interactions within communities. These multi-trophic level interactions affect the makeup of the community. We explored how predation impacts the strength of mutualism between ants and aphids on the plant Ligusticum porteri. It has been a base assumpti
Transitivity and structural balance in marmot social networks
Social relationships are composed of both positive (affiliative) and negative (agonistic) interactions, representing opposing effects. Social network theory predicts that positive relationships should be transitive; thus, the friend of a friend is more likely to be a friend. Further, when considerin
Mixed support for state maintaining risky personality traits in yellow-bellied marmots
In a variety of taxa, individuals behave in consistently different ways. However, there are relatively few studies that empirically test the potential mechanisms underlying the causes and maintenance of these personality differences. Several hypotheses for the causes and maintenance of risky persona
