Global climate change is a threat that continues to affect nearly every ecosystem on the planet through warmer temperatures, changes in precipitation patterns, and many other manifestations of a warmer world. Warming directly and indirectly affects plants and ecosystem functioning. In the natural wo

Invasive species are a major threat to biodiversity. Invasive plant species can alter ecosystems by outcompeting natives, lowering biodiversity, and change soil ecology. Additionally, invasive species can be costly to manage. Linaria vulgaris, a non-native noxious weed from Europe and Asia, was used

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

Manganese (Mn) plays a critical role in river water quality since Mn-oxides serve as

Pollinator mediated reproductive consequences of altered co-flowering under climate change depend on abiotic context

Evolutionary traps arise when organisms use novel, low-quality or even lethal resources based on previously reliable cues. Persistence of such maladaptive interactions depends not only on how individuals locate important resources, such as host plants, but also the mechanisms underlying poor perform

ANEMONE NARCISSIFLORA, L.-Six inches to a foot high, from a fibrous *Signs used: The degree (°) indicates feet.The minute (') indicates inches.The second ("') indicates lines, i. e. 4; of an inch.The hyphen means, to, i. e. 6-12' is 6 to 12 inches.The figures in parentheses are numbers under which t

Abiotic and biotic factors influence plant fitness by altering the physical environment and resource availability. According to the stress gradient hypothesis, increasing physical stress in an environment increases positive plant-plant interactions and decreases negative interspecies interactions. I

Mountain white-crowned sparrows’ (Zonotrichia leucophrys oriantha; hereafter MWCS) diet fluctuates across seasons given their changing nutrient requirements across life stages and environment. Insect population densities may influence the daily nest survival of MWCS who depend upon these organisms a

Network analyses can be used to examine multi-species interactions and have been applied to many ecological interactions such as food webs, antagonistic relationships such as plant- herbivory, and mutualistic relationships. A particular focus has been on plant-pollinator interactions given their imp

Nutrient cycling is crucial for proper functioning of aquatic ecosystems. Animals play an integral part of this process, especially in nutrient poor ecosystems such as the high elevation ponds at the Mexican Cut Nature Preserve. Nutrients such as nitrogen (N) and phosphorus (P) are both limiting nut

For many animals, group living is an effective strategy to mitigate predation risk and ensure survival. However, in yellow-bellied marmots (Marmota flaviventer), increased sociality is associated with lower female reproductive success, decreased female longevity, and increased over-winter mortality

WHO would not be attracted by the thought of a vacation spent on the Great Divide, that mighty crest of the conti nent, where towering peaks, jeweled lakes, tree-clad slopes, and green parks await the lover of nature and the out-of-doors? In the heart of this great mountain playground is the Cocheto
