Amy Yackel Adams, PhD
Amy Yackel Adams is a Research Ecologist focusing on improving management decisions of invasive reptiles worldwide.
Amy leads a diverse research program with other USGS scientists and various collaborators (NPS, USDA-NWRC, USFWS, DoD, universities, and state agencies) pertaining to early detection and rapid response, biology, ecology, genetics, control tool evaluation, eradication, and quantitative model development to improve adaptive management of invasive reptile species. Yackel Adams’ research areas in the Greater Everglades Ecosystem and Pacific Islands include: 1) Population and vital rate estimation of invasive Burmese Pythons, Veiled Chameleons, and Brown Treesnakes; 2) Estimating the impact of Brown Treesnakes on prey populations; 3) Enhancing early detection of invasive reptiles using new tools; and 4) Development and evaluation of removal and abundance models to inform and optimize eradication efforts.

Brown Treesnake trap captures, Guam National Wildlife Refuge, 2014 Brown Treesnake trap captures, Guam National Wildlife Refuge, 2014
Over a 22-week period both with and without active Brown Treesnake (BTS) snake removal, we evaluated snake-trap contact rates at mouse- and bird-lure traps within the Guam National Wildlife Refuge in 2014. Bird-lure traps served as a proxy for reintroduced nesting birds. Data consists of 3 files generated from camera surveillance and trapping using mouse and bird lures in conventional...
Offspring, dam, sire pedigree assignments in a managed population of Brown Treesnakes on Guam Offspring, dam, sire pedigree assignments in a managed population of Brown Treesnakes on Guam
In this dataset offspring are assigned to a dam and sire using information from single nucleotide polymorphisms (SNPs) from previously published pedigree reassignments of Brown Treesnakes within the U.S. Geological Survey's Brown Treesnake study enclosure on Northwest Field of Andersen Air Force Base, Guam (Levine and Yackel Adams 2021 and Nafus 2021) to update the overall pedigree...
Brown Treesnake detections on transects using potential attractants of live-mouse lures or fish-spray scent, Guam Brown Treesnake detections on transects using potential attractants of live-mouse lures or fish-spray scent, Guam
Nocturnal visual encounter surveys for Brown Treesnakes were collected and summarized into 4 plain text files (csv format): CapturesLure, SurveysLure, CapturesScent, and SurveysScent. Capture files contain unique Passive Integrated Transponder (PIT) tag identification and measurements of snakes with dates and locations of capture. Survey files contain the dates of transect sampling and...
Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python
Entire photo-documented sequence from 01 June 2021-09 September 2021, including novel interactions between intraguild predators in southern Florida - the native bobcat (Lynx rufus) and the invasive Burmese python (Python bivittatus). A bobcat depredated an unguarded Burmese python nest and subsequently the python exhibited nest defense behavior following the return of both animals to the...
Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019 Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019
These data reflect movement values for brown treesnakes from Guam that were translocated (moved by humans) to new locations or were resident (left in place) on Guam. The data are related to the specimen's treatment group, individual values, locations and other details affiliated with radio telemetry based acquisition and positional changes by the individual snakes across tracking events...
Brown Treesnake mating and reproductive success on Guam, 2004-2018 Brown Treesnake mating and reproductive success on Guam, 2004-2018
The mating and reproductive ecology of the invasive Brown Treesnake (Boiga irregularis) were generated by reconstructing a multigenerational genomic pedigree based on 654 single nucleotide polymorphisms for a geographically-closed population established in 2004 on Guam (N=426). The pedigree allowed annual estimates of individual mating and reproductive success to be inferred for snakes...

Divergent Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States Divergent Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States
Burmese python (Python bivittatus) is an invasive snake that has significantly affected ecosystems in southern Florida, United States. Aside from direct predation and competition, invasive species can also introduce nonnative pathogens that can adversely affect native species. The subfamily Serpentovirinae (order Nidovirales) is composed of positive-sense RNA viruses primarily found in...

Increasing the efficiency and power of camera traps for EDRR & ecological monitoring Increasing the efficiency and power of camera traps for EDRR & ecological monitoring
Invasive species are an ever-growing concern for Florida, especially in important environments like the Greater Everglades Ecosystem. One of the best ways to fight back against invasives is the use of the “Early Detection, Rapid Response” (EDRR) system. The earlier we can detect the presence of a nonnative species, and the faster we respond, the better our chance of stopping its spread...

Size distribution and reproductive phenology of the invasive Burmese python (Python molurus bivittatus) in the Greater Everglades Ecosystem, Florida, USA Size distribution and reproductive phenology of the invasive Burmese python (Python molurus bivittatus) in the Greater Everglades Ecosystem, Florida, USA
The design of successful invasive species control programs is often hindered by the absence of basic demographic data on the targeted population. Establishment of invasive Burmese pythons (Python molurus bivittatus) in the Greater Everglades Ecosystem, Florida USA has led to local precipitous declines (> 90%) of mesomammal populations and is also a major threat to native populations of...

Open removal models with temporary emigration and population dynamics to inform invasive animal management Open removal models with temporary emigration and population dynamics to inform invasive animal management
Removal sampling data are the primary source of monitoring information for many populations (e.g., invasive species, fisheries). Population dynamics, temporary emigration, and imperfect detection are common sources of variation in monitoring data and are key parameters for informing management. We developed two open robust-design removal models for simultaneously modeling population...

Invasive brown treesnakes (Boiga irregularis) move short distances and have small activity areas in a high prey environment Invasive brown treesnakes (Boiga irregularis) move short distances and have small activity areas in a high prey environment
Animal movements reflect temporal and spatial availability of resources as well as when, where, and how individuals access such resources. To test these relationships for a predatory reptile, we quantified the effects of prey abundance on the spatial ecology of invasive brown treesnakes (Boiga irregularis) on Guam. Five months after toxicant-mediated suppression of a brown treesnake...
