Abstract Climate change can impact plant fitness and population persistence directly through changing abiotic conditions and indirectly through its effects on species interactions. Pollination and seed predation are important biotic interactions that can impact plant fitness, but their impact on pop

Abstract The results of a gravity meter survey across the Wellington Field, Larimer County, Colorado, both before and after elimination of the regional effect is presented in relation to the subsurface structure of the field. The method of eliminating the regional effect is shown.This information is

Published data concerning the standard weight in lake trout ( Salvelinus namaycush ) and brown trout ( Salmo trutta ) have been established. The standard weights were used to compute relative weights for data collected in the spring and summer of 2011 for brown trout and lake trout in the Blue Mesa

Abstract. Hillslope similarity is an active topic in hydrology because of its importance in improving our understanding of hydrologic processes and enabling comparisons and paired studies. In this study, we propose a holistic bottom-up hillslope clustering based on a region's integrative hydrodynami

The nonlinearity and fear hypothesis predicts that highly aroused vocal mammals and birds produce vocalizations (notably alarm calls and screams) which contain a variety of nonlinear phenomena (NLP). Such vocalizations often sound “noisy” because vocal production systems are over-blown when animals

It is unclear how environmental change influences standing genetic variation in wild populations. Here, we characterised envi- ronmental conditions that protect versus erode polymorphic chemical defences in Boechera stricta (Brassicaceae), a short-­lived perennial wildflower. By manipulating drought

Understanding the factors controlling the relative abundance, distribution, and diversity of organisms is a fundamental challenge in ecology. For plants and animals, macroecological rules have been developed that describe these large-scale distributional patterns and attempt to explain the underlyin

Long-term soil CO2 emission measurements are necessary for detecting trends and interannual variability in the terrestrial carbon cycle. Such records are becoming increasingly valuable as ecosystems experience altered environmental conditions associated with climate change. From 2013 to 2021, we con

Noccaea caerulescens (formerly Thlaspi caerulescens, Brassicaceae) is a model species for studying the genetics and physiology of metal hyperaccumulation and is economically valuable for phytoremediation. Its growth and survival under varying natural conditions remain relatively unstudied but such i

Primary nectar-robbers feed through holes they make in flowers, often bypassing the plant's reproductive organs in the process. In many robbed plants, multiple holes are made in a single flower. Why a flower should be robbed repeatedly is difficult to understand: a hole signals that a nectar forager

AbstractHow bees shift the timing of their seasonal activity (phenology) to track favorable conditions influences the degree to which bee foraging and flowering plant reproduction overlap. While bee phenology is known to shift due to interannual climatic variation and experimental temperature manipu

Abstract Variations in tree water sources are important to understand in semi‐arid ecosystems because climatic shifts towards lower snowpack and increased drought affect water availability in subalpine forests of the western US. Here, we use daily in situ measurements of stable isotopes ( 2 H 18 O)

Climate change is simultaneously increasing atmospheric carbon dioxide concentrations ([CO2]) and temperatures. We conducted a multi-factorial growth chamber experiment to examine how these climate change factors interact to influence the expression of ecologically relevant morphological and phenolo

Riparian floodplains are important regions for biogeochemical cycling, including nitrogen. Here, we present MAGs from nitrifying microorganisms, including ammonia-oxidizing archaea (AOA) and comammox bacteria from Slate River (SR) floodplain sediments (Crested Bute, CO, US). Addi�onally, we explore MA

Abstract Insectivorous birds have ecologically important effects on prey abundance, behavior, and evolution, and through top‐down control, birds indirectly reduce herbivory and promote plant growth. While several studies sought to characterize biogeographic patterns in top‐down control by birds, var
