Armed conflict throughout the world's biodiversity hotspots poses a critical threat to conservation efforts. To date, research and policy have focused more on the ultimate outcomes of conflict for wildlife rather than on the ecological, social, and economic processes that create those outcomes. Yet the militarization that accompanies armed conflict, as well as consequent changes in governance, economies, and human settlement, has diverse influences on wildlife populations and habitats. To better understand these complex dynamics, we summarized 144 case studies from around the world and identified 24 distinct pathways linking armed conflict to wildlife outcomes. The most commonly cited pathways reflect changes to institutional and socioeconomic factors, rather than tactical aspects of conflict. Marked differences in the most salient pathways emerge across geographic regions and wildlife taxa. Our review demonstrates that mitigating the negative effects of conflict on biodiversity conservation requires a nuanced understanding of the ways in which conflict affects wildlife populations and communities.

“…Second, ponds close to the road also suffer from the risk of human‐mediated release of exotic turtles because of their easy accessibility, linking to the first factor discussed above. Although the overall trend of this negative factor is only marginally significant, this association is consistent with our previous conclusion that the road effect will negatively impact the native turtle population (Lin et al ., ).…”

“…In freshwater Testudines, habitat specialization has been shown to maintain partial reproductive isolation among different species (Via, ; De Busschere et al ., ). Based on our previous investigation, M. reevesii prefers ponds with dense vegetation inside and around the water body (Lin et al ., ), whereas M. sinensis seems to prefer open aquatic habitats at low elevations (Chen & Lue, ; also see the habitat description in Chen & Lue, , ). Human‐mediated dispersal facilitates encounters between the two turtles and disruption of their ecological boundary in nature.…”

“…In a comprehensive survey during 2004–2005, M. sinensis was not captured on these islands (Chen & Lue, ), indicating that this turtle had not yet established a stable population. However, the population size of this species seems to have increased during the last decade, possibly due to human‐mediated dispersal (Lin et al ., ). Similar cases among Mauremys species suggest that M. sinensis has the potential to breed with native M. reevesii and produce fertile hybrid offspring (Fong & Chen, ; Suzuki et al ., ; Xia et al ., ).…”

“…Given these conditions, the Kinmen Islands provide a valuable opportunity to study Reeves' turtle in the wild. This archipelago represents a recent case of protection of endangered wildlife in a demilitarized zone (DMZ) (You et al, 2013) and is one of very few sites in southeastern China sustaining a stable natural population of Reeves' turtle (Chen & Lue, 2010;Lin et al, 2015). Although located only 3 km from the coastline of continental China, these islands have been under military control by the Taiwanese government since the separation of the two political regimes after World War II.…”

Human disturbance as a possible cause of genetic introgression from exotic into native Mauremys turtles

The Kinmen Islands on the coastline of China represent a recent case of the protection of endangered wildlife in a demilitarized zone. These islands represent the last remaining habitat in southeastern China that supports a healthy natural population of Reeves’ turtle Mauremys reevesii. However, human‐mediated dispersal appears to have aided the establishment of an introduced population of the Chinese stripe‐necked turtle M. sinensis since the late 1990s, resulting in population mixture of the two congeners. To evaluate the potential impacts of hybridization, we evaluated the magnitude of genetic introgression in ponds on Kinmen using mitochondrial cytochrome b sequences and 13 microsatellite loci. We further used eight environmental and biological factors of the ponds to conduct general linear regression model analysis between environmental factors and the magnitude of genetic introgression. Among the 41 sampled ponds, M. reevesii was recorded in 21, of which 12 ponds (57.1%) contained genetic hybrids or backcrosses, corresponding to 11.3–12.7% of the total individuals on the islands. The magnitude of genetic introgression was positively correlated with the amount of introduced M. sinensis occurring in a pond, and marginally negatively associated with the shortest distance from the pond to secondary roads. We conclude that this considerable genetic introgression is attributable to human‐mediated dispersal of M. sinensis; roads and habitat modification may increase the likelihood of unexpected encounters between these two congeners.

Este trabajo busca corroborar la presencia de tortugas dulceacuícolas en la Reserva Ecológica Ciudad Universitaria-Costanera Norte, evaluar si existen variaciones mensuales en la abundancia relativa de alguna de las especies observadas y estudiar su comportamiento y uso del hábitat. Se realizaron avistajes semanales desde octubre de 2022 a junio de 2023, en cuatro puntos del humedal (HI1, HI2, HI3 y HC), entre 12:00 y las 16:00 h. Las tortugas observadas fueron identificadas y su comportamiento se clasificó en asoleamiento, desplazamiento y alimentación. Las variaciones en la abundancia relativa se analizaron por sitio mediante una prueba de Kruskal-Wallis, utilizando contrastes a posteriori de Benjamini-Hochberg si se encontraban diferencias entre meses. Detectamos la presencia de Phrynops hilarii, Trachemys dorbigni e Hydromedusa tectifera, siendo P. hilarii la única especie abundante y frecuente. No encontramos diferencias en la abundancia relativa de P. hilarii entre meses para HI2 (χ2=13.78; P=0.088) y HI3 (χ2=7.28; P=0.507), pero sí una mayor abundancia relativa en diciembre con respecto a mayo (z=-3.17; P.adj=0.028) y abril (z=-3.17; P.adj=0.028) en HI1, y en octubre en relación con noviembre (z=-2.99; P.adj=0.017), diciembre (z=-2.99; P.adj=0.017), enero (z=-2.99; P.adj=0.017), febrero (z=-2.99; P.adj=0.017), marzo (z=-2.99; P.adj=0.017) y junio (z=-2.99; P.adj=0.017) para HC. Los comportamientos de asoleamiento y desplazamiento se observaron en los cuatro puntos, mientras que la alimentación, solo en HI2 y HI3. Definimos áreas de asoleamiento en HI1 y HIC, asoleamiento y alimentación en HI2 y HI3, y tránsito en HI1, HI2 y HI3. Proponemos medidas de manejo para garantizar la conservación de las tortugas en la reserva.
