East River Surface and Pore Water FTICR-MS Data Associated with “Implications of sample treatment on characterization of the riverine environmental metabolome”
Surface and pore water samples were collected from distributed locations around Meander A in East River (Crested Butte, CO, USA) during the summer of 2018. This dataset consists of the characterization of dissolved organic matter using 12 Tesla Fourier transform ion cyclotron resonance mass spectrom

From individuals to ecosystem function: toward an integration of evolutionary and ecosystem ecology
An important goal in ecology is developing general theory on how the species composition of ecosystems is related to ecosystem properties and functions. Progress on this front is limited partly because of the need to identify mechanisms controlling functions that are common to a wide range of ecosys
Effects of aggregation size and host plant on the survival of an ant-tended Membracid (Hemiptera: Membracidae): potential roles in selecting for generalized host plant use
Abstract Insect herbivores that are tended by ants exhibit a range in host plant use from specialists to extreme generalists. Potential factors that may influence relative suitability of different host plants include the presence or absence of ants and the size of aggregations formed by nymphs feedi
Bridging the generation gap in plants: pollination, parental fecundity, and offspring demography
Despite extensive study of pollination and plant reproduction on the one hand, and of plant demography on the other, we know remarkably little about links between seed production in successive generations, and hence about long-term population consequences of variation in pollination success. We brid
Predator effects on prey population dynamics in open systems
It is concluded that predation alone cannot explain variation in population dynamics of either mayfly species; and the relative importance of predation is species- and environment-specific compared to non-predatory losses, such as other agents of mortality and non-consumptive effects of predators.
Consumptive and non-consumptive effects of predators on metacommunities of competing prey
Although predators affect prey both via consumption and by changing prey migration behavior, the interplay between these two effects is rarely incorporated into spatial models of predator–prey dynamics and competition among prey. We develop a model where generalist predators have consumptive effects
Indirect fitness benefits do not compensate for the loss of direct fitness in yellow-bellied marmots
Abstract The contribution of indirect fitness to inclusive fitness is expected to increase as the reproductive skew increases, with indirect fitness being the only component of inclusive fitness of sterile individuals in eusocial species. However, the relative contribution of indirect fitness to inc
Longevity can buffer plant and animal populations against changing climatic uncertainty.
Senescence rates are determined by ranking on the fast-slow life-history continuum
AbstractComparative analyses of survival senescence by using life tables have identified generalizations including the observation that mammals senesce faster than similar‐sized birds. These generalizations have been challenged because of limitations of life‐table approaches and the growing apprecia
Diet and a developmental time constraint alter life-history trade-offs in a caddis fly (Trichoptera: Limnephilidae)
Environmental factors influence variation in life histories by affecting growth, development, and reproduction. We conducted an experiment in outdoor mesocosms to examine how diet and a time constraint on juvenile development (pond-drying) influence life-history trade-offs (growth, development, adul
Mechanisms of tolerance to floral larceny in two animal-pollinated wildflowers, <i>Polemonium viscosum</i> and <i>Ipomopsis aggregata</i>
Effects of climate change on phenology, frost damage, and floral abundance of montane wildflowers
The timing of life history traits is central to lifetime fitness and nowhere is this more evident or well studied as in the phenology of flowering in governing plant reproductive success. Recent changes in the timing of environmental events attributable to climate change, such as the date of snowmel
