The massive release of captive-bred native species (“intentional release”) is a pervasive method to enhance wild populations commercial and recreational species. However, such external inputs may disrupt the sensitive interactions that allow competing coexist, potentially compromising long-term community stability. Here, we use theory data stream fish communities show intentional destabilizes dynamics with limited demographic benefit enhanced Our predicted intensifies interspecific competition, facilitating competitive exclusion unenhanced otherwise stably coexist. In parallel, excessive input individuals suppressed natural recruitment via intensified within-species competition. Consequently, ecological reduced density unstable temporal dynamics. Consistent this prediction, showed greater fluctuations fewer taxonomic richness in rivers intensive hatchery salmon—a major fishery resource worldwide. findings alarm current overreliance on accelerate global biodiversity loss undesired consequences for provisioning ecosystem services.

Abstract Recovery of endangered species is challenging and lengthy, especially when it involves reintroduction dynamic environmental conditions. Because managers often need to decide between many management strategies with uncertain outcomes, periodically assessing progress toward recovery using population viability analysis (PVA) can help guide decision‐making. We developed a PVA for the critically Puerto Rican parrot ( Amazona vittata ) evaluate current status potential future reach goals set in Plan. Having grown from their nadir 13 birds 1976 686 2021, effort has made great progress. Using 15 years data, we built an individual‐based that included interactions two captive three wild populations connected via annual releases. If continues as planned, have no moderate risks extinction (0–32%) over next 100 years. However, remain dependent on releases sustain growth, targets stable growth connectivity not yet been reached. Our suggests hurricanes are impediment reaching impact some more than others based geography. Projections climate‐change‐induced higher hurricane resulted being less likely stabilize. identified demographic rates associated could positively populations: increasing reproduction (e.g., artificial nests, improving nest success) decreasing first‐year mortality targeted predator control). Based our understanding demographics, will continue be management‐dependent unless altered.

Abstract Long-lived territorial bird populations often consist of a few breeding adults and many nonbreeding individuals. Some are threatened by anthropogenic activities, because human conflicts for high-quality habitat. Therefore, habitat restoration projects have been widely implemented to improve avian population status. In conjunction with restoration, conservation translocations increasingly implemented. Adequate nonbreeder survival can be key factor in the success these attempts birds may represent reservoirs replacement breeders. The maintenance pair numbers is also influenced transition rate nonbreeders reintroduction Oriental Stork (Ciconia boyciana), long-lived, territorial, endangered species, was initiated Japan 2005 using captive hopes increasing population’s use restored Our objective this study elucidate factors determining reintroduced stork recruitment populations. We estimated participation sex, age, generation, wild-born or not, haplotypes, status storks during 2005–2022 Bayesian hierarchical models.

Abstract Evaluating population responses to management is a crucial component of successful conservation programs. Models predicting growth under different scenarios can provide key insights into the efficacy specific actions both in reversing decline and maintaining recovered populations. Bald eagle ( Haliaeetus leucocephalus ) United States has seen many successes over last 50 years, yet extent which bald Arizona, an important within Southwest region, remains area debate. Estimates species' trend evaluation ongoing nest‐level practices are needed inform decisions. We developed Bayesian integrated model (IPM) viability analysis (PVA) using 36‐year dataset assess Arizona dynamics their underlying demographic rates current possible future practices. estimated that grew from 77 females 1993 180 2022, average yearly increase 3%. Breeding sites had trained personnel (i.e., nestwatchers) stationed at active nests mitigate human disturbance 28% higher reproductive output than without this protection. Uncertainty around trends was high, but continued nestwatcher program were less likely predict abundance declines nestwatchers. Here, IPM‐PVA framework provides useful tool for estimating effectiveness past exploring needs delisted population, highlighting action may be necessary maintain even after meeting certain recovery criteria.

Reintroductions are increasingly used for re‐establishing populations, though the documented success rates variable. Success is typically measured by survival and breeding of released individuals subsequent establishment growth population. However, few studies quantify demographic reintroduced populations long‐lived species, with slower dynamics lower reproductive rates, generations, which determine population persistence, often unknown. We document reintroduction Common Crane Grus grus to south‐west England in UK, using analysis modelling whether overarching aim establishing a self‐sustaining likely be achieved. Between 2010 2014, 93 Cranes were hatched from wild eggs, custom‐reared soft‐released into suitable habitat. Survival all age‐classes was apparently higher than healthy individuals, particularly juvenile age‐classes, females males. Productivity relatively low, but increased age. Assuming that generations at levels estimated captive‐reared population, slow positive predicted over next 30 years. Sensitivity analyses showed persistence this sensitive even slight decrease values adult survival, impacted lesser extent productivity. This study highlights ability achieve despite low productivity when exceptionally high. It also illustrates need long‐term monitoring establish animals have life histories: 9 years after initial releases, remains dominated first‐generation birds skewed transient age‐structure late onset success.
