Introduction
Heidi Golden is a scientific consultant and founder of Golden Ecology LLC (www.goldenecology.com). She is a broadly trained, highly experienced ecologist with a focus on movement, ecology, and evolution of fish, including accompanying genetics, population, and trophic level drivers. Her academic research investigates ecological and evolutionary roles species play in ecosystems at different temporal and spatial scales.

Acanthobdellida gnaw into the sides of salmonid fishes in frigid Arctic lakes and rivers, latching on with fearsome facial hooks. Sister to leeches, they are an ancient lineage with two described species. Unfortunately, Acanthobdellida are rarely collected, leading to a paucity of literature despite their unique morphology. Populations range from E...

In recent decades, anthropogenic and natural disturbances have increased in rate and intensity around the world, leaving few ecosystems unaffected. As a result of the interactions among these multiple disturbances, many biological communities now occur in a degraded state as collections of fragmented ecological pieces. Restoration strategies are tr...
Conserving biodiversity in an era of rapid climate change requires understanding the mechanisms that influence dispersal, gene flow and, ultimately, species persistence. This information is becoming critical for conserving key species in rapidly warming places such as the Arctic. Arctic freshwater fish not only face warmer conditions, but also the...
Climate change is altering ecosystems across the globe, with ecological and evolutionary consequences affecting species persistence and biodiversity. I investigated the effects of changing hydrology on Arctic grayling (Thymallus arcticus) metapopulation structure, microgeographic differentiation, movement patterns and vital rates using neutral gene...
This chapter examines the basic ecology of streams in the Toolik Region. It prov information gathered from monitoring year-to-year variability and to identify long-term changes in the ecology of streams. It looks into the importance of understanding the role nutrients have in limiting and structuring stream ecosystems. It describes the ecological c...
The prolonged swimming speed and metabolic rate of 0+ year Arctic grayling Thymallus articus were examined with respect to current velocity, water temperature and fish size, and compared to conditions fish occupy in the river. Oxygen consumption (mg O2 h−1) increased with fish mass and temperature (6–23° C), with a steep increase in metabolic rate...
1.Anthropogenic-derived nutrient inputs to coastal environments have increased dramatically worldwide in the latter half of the 20th century and are altering coastal ecosystems. We evaluated the effects of nitrogen loading on changes in macrophyte community structure and the associated fauna of a north temperate estuary. We found that a shift in pr...
We examined the influence of river discharge and temperature on growth of adult and age-0 Arctic grayling Thymallus arcticus in the Kuparuk River (1985-1996) and Oksrukuyik Creek (1990-1996) during the Arctic growing season (late June to mid-August). Grayling growth was compared against six physical variables (river, nutrient level, mean summer dis...

1. Young (0+) Arctic grayling (Thymallus arcticus) have the potential to control the trophic structure of Arctic tundra streams through consumption, nutrient excretion and the modification of prey behaviour. The effect of young grayling on three trophic levels (algae, invertebrates and fish) was investigated by manipulating fish density and by fert...
This study examined the relative importance of bottom-up and top-down controls of an arctic stream food web by simultaneous manipulation of the top predator and nutrient availability. We created a two-step trophic system (algae to insects) by removal of the top predator (Arctic grayling, Thyrnallus arcticus) in fertilized and control stream reaches...
