Developing population models for assessing risks to terrestrial plant species listed as threatened or endangered under the Endangered Species Act (ESA) is challenging given a paucity of data on their life‐history. The purpose of this study was to develop a novel approach for identifying relatively data‐rich non‐listed species that could serve as re...

The assimilation of population models into Ecological Risk Assessment (ERA) has been hindered by their range of complexity, uncertainty, resource investment, and data availability. Likewise, ensuring that the models address risk assessment objectives has been challenging. Recent research efforts have begun to tackle these challenges by creating an...

Population models can provide valuable tools for Ecological Risk Assessment (ERA). A growing amount of work on model development and documentation is now available to guide modelers and risk assessors to address different ERA questions. However, there remain misconceptions about population models for ERA, and communication between regulators and mo...

In this paper, we analyze the impact of data gaps in the context of ecotoxicology when parameterizing a species using a widely recognized theory, the Dynamic Energy Budget (DEB) theory. DEB-based models are used in many ecological domains, and have been recognized as particularly useful in ecotoxicology. However, available datasets are often insuff...

Despite widespread acceptance of the utility of population modeling and advocacy of these approaches for a more ecologically relevant perspective, they are not routinely incorporated in ecological risk assessments (ERA). A systematic framework for situation-specific model development is one of the major challenges to broadly adopting population mod...

Pesticide risk assessment for “listed” (threatened and endangered) species is hampered by a lack of quantitative demographic information. Demographic information for non‐listed species could inform risk assessments and recovery plans for listed species, however it is unclear how representative demography of the former is of the latter. We performed...

Population models are used as tools in species management and conservation and are increasingly recognized as important tools in pesticide risk assessments. A wide variety of population model applications and resources on modeling techniques, evaluation and documentation can be found in the literature. In this paper, we add to these resources by in...

Estimating and projecting population trends using population viability analysis (PVA) are central to identifying species at risk of extinction and for informing conservation management strategies. Models for PVA generally fall within two categories, scalar (count-based) or matrix (demographic). Model structure, process error, measurement error, and...

Background/Question/Methods Population viability analysis (PVA) is commonly used to assess population trends and inform conservation management strategies. Models used in PVA generally fall within two categories, scalar (count based) or matrix (demographic) models. Both model types are often parameterized by time series data. Choice of model type...

Background/Question/Methods Assessing population trends is essential to ascertaining a taxon’s threat status and to the development of conservation management strategies. A widely used tool for this task is population viability analysis (PVA), where population models are used to estimate risk of decline or extinction within a specified time horiz...

Brood parasitic birds such as cowbirds (Molothrus spp., Icteridae) lay their eggs in the nests of other species, abandoning them to be incubated and raised by the hosts. Lack of investment in parental care results in high annual fecundities of female parasitic birds. Brood parasites lay eggs in series or clutches, separated by gaps or non-laying in...
