SPLASH Field Study; CLAMPS2 Doppler Lidar VAD Data (NCEI Accession 0304717)

These files contain 24-hour periods of data collected from the CLAMPS2 Halo Streamline XR+ Doppler lidar. The Doppler lidar conducts regular conical scans at a set elevation angle. These data are then passed through a typical VAD algorithm to retrieve horizontal wind speed and direction profiles. Th

Determining pollinator behavior differences bumblebees and flies.

Pollinator behavior is integral to understanding community network interactions. These interactions can serve as a proxy for community health. This study aims to compare the behavior between bumblebee pollinators and fly pollinators. This will take place around the area of Gothic, CO, at an elevatio

Are juvenile female golden mantle ground squirrels dispersing from their natal burrow due to high-stress levels?

Many mammals disperse from the area they were born in. Dispersal is done to avoid inbreeding, resources, and mate competition. Dispersal in mammals tends to be male-biased as juvenile males are the ones that often leave their natal burrow, and females do not. The cost of dispersal is expensive as ma

Effects of Altitude on the Growth, Mortality, and Recruitment of Subalpine Tree Species in the West Elk Mountains of Colorado.

Subalpine ecosystems in Colorado occur between 9,000-11,000ft in elevation and are composed of several species of conifers. The elevation range of each species is slightly different, but they tend to form established communities, such as the Engelmann spruce-subalpine fir community. It has been show

Characterization of thermal tolerance in sub-alpine bumblebee species

Temperature is one of the limiting factors of life, and it influences an organism’s growth, sexual reproduction, sexual determination, distribution, and metabolism. the interaction between temperature and organisms therefore an essential component of their ecology. Temperature impacts organisms in d

Looking through leftovers: an analysis of bee bowl bycatch

In this lab I analyzed the species composition of arthropods in bee bowl bycatch. The results of an analysis of these different communities show a significant difference in the compositional Orders of arthropods found in both the bowl colors and among the different sites along an elevational gradien

The Impact of Environmental Factors on Arizona Tiger Salamander Larval Growth

Amphibians have been hit particularly hard by the recent era of biodiversity loss (Collins 2009). Understanding the factors that influence their growth and development can help us understand their global decline as well as the dynamics of populations in widely different habitats. Growth rates have b

Limnephilus externus Case Grazing

The subalpine region of Colorado hosts a variety of aquatic habitats. The organisms that inhabit these ecosystems are presented with many ecological adversities and differing predator guilds.

Effects of a caddisfly range shift on competition and facilitation in high elevation ponds

As temperatures warm, the climate crisis is having a significant influence on species all across the world and altering their distributions. Colorado's high elevation ponds have recently observed a species range shift, traveling to higher altitudes than they have previously inhabited. The Mexican Cu

The (surprising) importance of males in a matrilineal society: behavioural insights from a topological knockout study

Social group structure often has consequences for individual fitness and ecological and evolutionary processes, but group structure is not fixed because of demographic processes: individuals die, disperse or are recruited into social groups. Thus, it is important to understand how demographic social

Agonistic and affiliative social relationships are associated with marmot docility but not boldness

All animals must face predation risks at some points in their lives and individuals may vary in how much risk they are willing to accept. While it is well recognized that sociality is a way to manage risks, and social group size effects are well studied, the specific ways in which different types of

Individual life histories: neither slow nor fast, just diverse

The slow-fast continuum is a commonly used framework to describe variation in life-history strategies across species. Individual life histories have also been assumed to follow a similar pattern, especially in the pace-of-life syndrome literature. However, whether a slow-fast continuum commonly expl

Differential response of three large mammal species to human recreation in the Rocky Mountains of Colorado, USA

Outdoor recreation benefits local economies, environmental education, and public health and wellbeing, but it can also adversely affect local ecosystems. Human presence in natural areas alters feeding and reproductive behaviors, physiology, and population structure in many wildlife species, often re
