#### Towards an Integrated Understanding of Terrestrial Evapotranspiration

Terrestrial evapotranspiration (ET), the second-largest component of the terrestrial water cycle, links water, energy, and carbon cycles and influences the productivity and health of our ecosystems. Despite the importance of ET, the dynamics of ET across a spectrum of spatiotemporal scale and their controls are uncertain. During an international ET workshop held in November 2021 by AmeriFlux, the

#### Fiber Optic Seismology for Earthquake Hazards Research, Monitoring and Early Warning

A revolution is underway in seismology that transforms fiber-optic cables into arrays of thousands of seismic sensors. Compared to the traditional monitoring networks using inertial seismometers, the fiber-optic approach can increase the spatial data density by orders of magnitude and enable data processing methodologies that require a high-fidelity wavefield. The Working Group aims to advance the

#### Using a network of networks for high-frequency multi-depth soil moisture observations to infer spatial and temporal drivers of subsurface preferential flow

Subsurface preferential flow (PF = water bypassing the soil matrix) provides rapid flowpaths for water and any substances transported with it, thereby profoundly impacting the recharge of aquifers, the spreading of contaminants, the health of the soil, and the functioning of ecosystems. It involves a complexity of processes that are poorly understood to the degree that current science provides no

#### Renewable Resilience: City-Scale Geothermal Energy Everywhere

Despite the proven efficacy of geothermal energy as a city-scale heating and cooling resource, the relative newness of most city-scale applications using diverse technologies has resulted in limited widespread adoption. We aim to develop authoritative information suitable for city-managers and other decision-makers. Geothermal resources are ubiquitous and diverse, with technologies available bot

#### Synthesizing patterns and drivers of changes in lake zooplankton community dynamics worldwide

Despite the critical services freshwater systems provide, freshwater biodiversity has been vastly under-studied compared to terrestrial and marine biomes. In fact, systematic compilations of freshwater zooplankton are surprisingly rare despite the critical roles zooplankton play in regulating and supporting ecosystem services, serving as key indicator species, and consequently, influencing emergen

#### Beyond waves and shifting sand: considering ecosystem processes in forecasts of coastal landscape change

Sea-level rise and storms cause major changes on coastal landscapes, including shifts in elevation, ecosystem type (for example, dunes and tidal wetlands), soils, and plant communities. Because these changes can have impacts on human communities, the local economy, and ecosystems, understanding how, when, and why these changes occur can be important for informing policy and natural resource manage

#### Standardizing, aggregating, analyzing and disseminating global wildlife genetic and genomic data for improved management and advancement of community best practices

Global biodiversity is rapidly declining, threatening humans, ecosystems, and the services that society relies upon. Monitoring and understanding the extent of biodiversity declines can support policy decisions. Genetic diversity is the foundation of biodiversity, determining the capacity of populations to adapt to environmental changes and to sustain function and structure in all ecosystems. Whil

#### Synthesis of the new North American tree-ring fire-scar network: using past and present fire-climate relationships to improve projections of future wildfire

Increasing wildfire activity in much of North America is having severe impacts on society and ecosystems. Climate change is a key driver of changing fire regimes across North America, with varying expressions across the continent. Modern fire records, while useful, are too short to fully characterize the complex patterns and non-linear dynamics of fire-climate relationships that are required to un

#### Developing a macroecological understanding of invasive plant impacts based on abundance and trait data

Understanding invasive plant impacts can provide insight into community assembly and inform the development of successful management strategies. The impacts of invasive species depend on how they alter patterns of abundance within recipient communities and on the characteristics of the invaders and the affected species. Research has suggested that common species may be more impacted by invasions,

#### Translational science for renewable energy and its wildlife concerns: a synthesis of wind energy buildout, bat population ecology, and habitat constraints

Wind energy is poised for rapid growth over the next 2-3 decades yet fatalities to birds and bats is a leading concern that may constrain wind energy development in the US. This working group will integrate wind energy forecasting models with bat ecological models and management policy considerations to transform our ability to understand and manage renewable energy development while minimizing un
