Reach and Effectiveness of Conservation Translocations When Founder Animals Are Sourced From Zoos

Animal Conservation, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

ABSTRACT Conservation translocations (e.g., reintroductions) are an important tool to replenish wildlife populations and manage biodiversity in lieu of emerging threats around the globe. Determining available effective founder animal sources evaluating outcomes conservation critical help mitigate challenges maximize opportunities. Zoos aquaria have a history broad engagement, but global assessment that used zoo‐sourced animals is lacking. We reviewed publications sourced founders from zoos ( n = 117) qualitatively quantitatively assessed trends factors associated with post‐release monitoring (PRM) duration author‐perceived project outcomes. Confirmed reproduction occurring recipient population(s) was longer PRM durations. Projects having long‐term objectives ex situ preconditioning (i.e., enriched for adaptability) had lower odds author‐deemed translocation failure. Notably, rate perceived failures among projects (8.6%) when compared broader various (20.9%). zoo reach across varying species risk statuses, although common regional taxonomic biases remain. This review provides support can lead identifies useful linked unsuccessful Founder quality over quantity may be key—sourcing individuals optimal survival viability long term will paramount. standardized reporting all recommend practitioners opportunities engage early planning stages assess feasibility inform strategies facilitate situ–in spectrum.

Translocation in a fragmented river provides demographic benefits for imperiled fishes

Ecosphere, Journal Year: 2024, Volume and Issue: 15(5)

Published: May 1, 2024

Abstract Fragmentation isolates individuals and restricts access to valuable habitat with severe consequences for populations, such as reduced gene flow, disruption of recolonization dynamics, resiliency disturbance, changes in aquatic community structure. Translocations mitigate the effects fragmentation loss are common, but few rigorously evaluated, particularly fishes. Over six years, we translocated 1215 four species imperiled fish isolated below a barrier on San Juan River, Utah, USA, that upstream habitat. We used re‐encounter data (both passive integrated transponder tag telemetry detections physical recaptures) collected between 2016 2023, inform spatially explicit multistate mark–recapture model estimated survival transition probabilities non‐translocated individuals, both above barrier. Individuals all moved large (>200 km) distances following translocation, maximum encounter distance varying by species. Results from suggested survived at higher rate compared three Above barrier, similar rates bluehead sucker ( Catostomus discobolus ) flannelmouth latipinnis ), while endangered Colorado pikeminnow Ptychocheilus lucius ; mean, 95% CI: 0.75, 0.55–0.88) razorback Xyrauchen texanus 0.86, 0.75–0.92) were relative (Colorado pikeminnow: 0.52, 0.51–0.54; sucker: 0.74–0.75).

Further, given costs or delays providing engineered passage structures achieving dam removal, translocations may provide an alternative conservation strategy fragmented river systems.

Biological control for One Health

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 951, P. 175800 - 175800

Published: Aug. 26, 2024

Biological control has been effectively exploited by mankind since 300 CE. By promoting the natural regulation of pests, weeds, and diseases, it produces societal benefits at food-environment-health nexus. Here we scrutinize biological endeavours their social-ecological outcomes through a holistic 'One-Health' lens, recognizing that health humans, animals, plants, wider environment are linked interdependent. Evidence shows generates desirable within all One Health dimensions, mitigating global change issues such as chemical pollution, biocide resistance, biodiversity loss, habitat destruction. Yet, its cross-disciplinary achievements remain underappreciated. To remedy this, advocate systems-level, integrated approach to research, policy, practice. Framing in context helps unite medical veterinary personnel, ecologists, conservationists agricultural professionals joint quest for solutions some most pressing planetary health.

Conservation science and the ethos of restraint

Conservation Science and Practice, Journal Year: 2021, Volume and Issue: 3(4)

Published: Feb. 20, 2021

Abstract Despite aiming to make conservation science and practice more effective, many conservationists default excessive precaution, advocating conservative actions—or even inaction. The field suffers from an understandable aversion unintended consequences, especially for approaches involving biotechnology “next‐generation” interventions. We call this precautionary attitude among the ethos of restraint argue replacing it with responsible action . Loosening will require (a) holistically accounting comparative risks, benefits, costs novel approaches; (b) gathering data on their consequences; (c) engaging in dialogue about intended consequences values; (d) pursuing adaptive implementation strategies. Adopting requires grasping that precaution proaction are not diametrically opposed attitudes. Instead, we must decide what level or is warranted, do, a case‐by‐case basis.

Social feasibility assessments in conservation translocations

Trends in Ecology & Evolution, Journal Year: 2022, Volume and Issue: 38(5), P. 459 - 472

Published: Dec. 23, 2022

Improving the effectiveness of conservation translocations could contribute to reversing global biodiversity loss. Although evaluations ecological factors affecting translocation outcomes are commonplace, consideration human social remains rare, hindering improvements this practice. We analysed 550 case studies explore inclusion in project feasibility assessments. Reviewed projects often failed assess feasibility, and assessments, where attempted, tended be narrow scope. Consequently, challenges such as proactively addressing conflict remained unaddressed. Insufficient knowledge sharing prioritisation detriment remain barriers effective planning. Successful linked early assessment establishment long-term commitments between people, places, partners.

Abstract The colonization of suitable yet unoccupied habitat due to natural dispersal or human introduction can benefit recovery threatened species. Predicting suitability and conflict potential areas facilitate conservation planning. Planning for reintroduction gray wolves ( Canis lupus ) the US state Colorado is underway. Assessing which occupancy sites minimize likelihood human–wolf during events seasonal movements critical success this initiative. We used a spatial absorbing Markov chain (SAMC) framework, extends random walk theory probabilistically accounts both movement behaviour mortality risk, compare viability (public lands >500 km 2 minimally meet wolf pack range area). SAMC framework produced spatially explicit predictions dispersal, philopatry risk ahead recolonization prior efforts. Our model included: (1) resistance based on terrain, roads housing density; (2) (absorption) livestock presence, social tolerance, land ownership boundaries; (3) site fidelity quality. Using model, we compared 21 public units by deriving of: (A) relative survival time outside each site, (B) intensity use retention within (C) probability adjacent lands. also predicted mapped hotspots associated with site. Among assessed, complex USFS Wilderness near Aspen, chiefly Hunter‐Fryingpan Collegiate Peaks areas, had best overall rankings when comparing metric. area balances high‐quality, well‐connected relatively low density high tolerance.
