Eradication via destratification: whole-lake mixing to selectively remove rainbow smelt, a cold-water invasive species.
Rainbow smelt (Osmerus mordax) are an invasive species associated with several negative changes to lake ecosystems in northern Wisconsin. We combined empirically based bioenergetics models with empirically based hydrodynamic models to assess lake destratification as a potential rainbow smelt eradication method. The dataset reported here is the otolith data from 20 age 1plus individuals.
Invasive rat eradication effects on seedling counts on Palmyra Atoll, 2004-2016
In order to investigate the impacts of rat eradication on plant communities on the Palmyra Atoll, Line Islands, Central Pacific Ocean ecosystem, a study was conducted surveying the native and non-native tree and palm seedling abundance before and after an eradication event which took place in June 2011. The common plant species examined were P. grandis and C. nucifera, while the less-common species were B. asiatica, C. subcordata, H. sonora, G. speciosa, N. oppositifolium, and C. inophyllum. Data for common plant species were collected in 2007, 2011, 2012, 2014, and 2016, and for less-common species in 2004, 2011, 2012, 2014, and 2016. Data were collected via survey methods; 55 transect sites were examined for the common species, and between 49 to 55 sites were examined depending on the year, for the less-common species.

A call to eradicate non-inclusive terms from science
<p>Source code and data associated with a commentary (Khan, 2021; eLife) that shows an increase of non-inclusive terms with racial connotations used in life-science literature and calls for action to make science inclusive for all.</p>
Gene drives for vertebrate pest control: realistic spatial modelling of eradication probabilities and times for island mouse populations
<p>Invasive alien species continue to threaten global biodiversity. CRISPR-based gene drives, which can theoretically spread through populations despite imparting a fitness cost, could be used to suppress or eradicate pest populations. We develop an individual-based, spatially explicit, stochastic model to simulate the ability of CRISPR-based homing and X-chromosome shredding drives to eradicate populations of invasive mice (Mus muculus) from islands. Using the model, we explore the interactive effect of the efficiency of the drive constructs and the spatial ecology of the target population on the outcome of a gene-drive release. We also consider the impact of polyandrous mating and sperm competition, which could compromise the efficacy of some gene-drive strategies. Our results show that both drive strategies could be used to eradicate large populations of mice. Whereas parameters related to drive efficiency and demography strongly influence drive performance, we find that sperm competition following polyandrous mating is unlikely to impact the outcome of an eradication effort substantially. Assumptions regarding the spatial ecology of mice influenced the probability of and time required for eradication, with short-range dispersal capabilities and limited mate-search areas producing `chase' dynamics across the island characterised by cycles of local extinction and recolonization by mice. We also show that highly efficient drives are not always optimal, when dispersal capabilities are low, rapid local population supression around the introduction sites can cause loss of the gene drive before it can spread to the entire island. We conclude that, although the design of efficient gene drives is undoubtedly critical, accurate data on the spatial ecology of target species is critical for predicting the result of a gene-drive release.</p>

Early detection at the Loxahatchee National Wildlife Refuge by a University researcher prompted a concerted effort to capture birds and employ the scout technique on two transmitter affixed birds. The scout method and reported species sightings resulted in identifying additional roost locations (4) where shooting operations took place.
