Abstract Aichi Target 12 of the Convention on Biological Diversity (CBD) contains aim to ‘prevent extinctions known threatened species’. To measure degree which this was achieved, we used expert elicitation estimate number bird and mammal species whose were prevented by conservation action in 1993–2020 (the lifetime CBD) 2010–2020 timing 12). We found that 21–32 7–16 since 1993, 9–18 two seven 2010. Many remain highly may still become extinct. Considering 10 five did go extinct (or are...
Invasive alien species are a major threat to native insular species. Eradicating invasive mammals from islands is feasible and proven approach prevent biodiversity loss. We developed conceptual framework identify globally important for mammal eradications imminent extinctions of highly threatened using biogeographic technical factors, plus novel consider socio-political feasibility. applied this comprehensive dataset describing the distribution 1,184 vertebrate (i.e. those listed as...

Abstract Eradications of invasive rodents from tropical islands have a lower success rate compared to temperate islands. In the tropics wide range physical and biological conditions results in variety island biomes, with unique challenges windows opportunity for rodent eradications. We describe compare research operational details six successful eradications mice Mus musculus ship rats Rattus rattus carried out during 2011–2015. The work was conducted on two distinct archipelagos Mexico (one...
The Baja California Pacific Islands (BCPI) is a seabird hotspot in the southern Current System supporting 129 breeding populations of 23 species and over one million birds annually. These islands had history environmental degradation because invasive alien species, human disturbance, contaminants that caused extirpation 27 populations. Most mammals have been eradicated colonies restored with social attraction techniques. We recorded number pairs annually for most since 2008. To assess...
Guadalupe Island, off the Baja California peninsula, México, hosts most important growing Laysan Albatross (Phoebastria immutabilis) breeding colony in eastern Pacific. Since this seabird's first arrival 1983, it has been affected by predation from feral cats (Felis catus), present on since late 19th century. Heavy events have recorded island, so we initiated a cat control campaign 2003 and began collecting baseline information for developing an eradication plan. At same time, conducted...
Science-based planning and prioritization can help achieve greater return on investment of limited conservation funds. We conducted a GIS-based multicriteria decision analysis to prioritize efforts eradicate populations invasive alien species that threaten native biota the islands Mexico. evaluated 29 Mexican with documented presence mammals characterized following attributes each island: endemic taxa, threatened species, important seabird nesting areas, richness, likelihood reinvasion,...
Socorro Island, in the Revillagigedo Archipelago, has highest number of endemisms any Mexican island. It provides habitat for 117 vascular plants, 26 % which are endemic to Also island one reptile and eight terrestrial bird species. However, local ecosystem been heavily degraded by exotic mammals over past 140 years. The feral sheep (Ovis aries) contributed a 30% loss based on island's surface area. Another serious threat is cat (Felis catus), severely impacted communities tree lizard...
Sexual dimorphism in the Laysan albatross (Phoebastria immutabilis) on Guadalupe Island was evaluated during breeding seasons of 2015-2018 by measuring and comparing 10 morphological attributes: cranial length, bill nostril width, height, tarsus closed wing opened wingspan length reproductive adults (n = 135). Males were larger than females across all traits (Student's t-test, p < 0.05, 0.05). We created a logistic model using stepwise regression to predict sex based variables. This...
Isla Socorro es una isla oceánica rica en biodiversidad y endemismos. Sin embargo, la ha sido impactada por el gato asilvestrado desde 1957. A través del análisis contenido estomacal de 79 gatos se determinó dieta este depredador, cual está constituida mayormente ratón doméstico (Mus musculus, 22.16%), lagartija endémica (Urosaurus auriculatus, 15.09%), residuos antropogénicos (15.09%), e insectos (Orthoptera, 13.20%). Se identificó ámbito hogareño los a telemetría, utilizando cuatro...

San Benito Archipelago is internationally important for the conservation of 13 species seabirds. Oeste, largest and only inhabited island, was declared mammal-free in 2000 after a series eradications conducted collaboration between fishing cooperative Pescadores Nacionales de Abulón, Mexican organization, Grupo Ecología y Conservación Islas, A.C., Government. The archipelago remained until 2006, when an unusual invader, Cedros island cactus mouse (Peromyscus eremicus cedrosensis),...
