“…The main causes of declines in Colombia are overexploited for human consumption, habitat loss or degradation, and the construction of hydroelectric power plants (Morales-Betancourt, Lasso, Trujillo, De La Ossa, Forero, and Páez, (2012), Morales-Betancourt, Lasso, Páez, Trujillo, Vargas-Ramírez, Forero-Medina, Hernández, and Trujullo (2012)). Recently, two species from northern Colombia were identified as high priorities for conservation (Forero-Medina et al., 2016; Morales-Betancourt, Lasso, et al., 2015, Morales-Betancourt, Páez, and Lasso, 2015). One is Podocnemis lewyana (Duméril, 1852), the Magdalena River Turtle.…”

The endemic species Podocnemis lewyana, the Magdalena River turtle, is listed worldwide as one of the turtle species at highest risk of extinction, and Trachemys callirostris, the Colombian slider, is the most trafficked turtle species in Colombia. An ethnozoological approach was used to analyze people's attitudes and perceptions on the effectiveness of conservation programs for these species and to identify conservation measures that would contribute to turtle population sustainability. Available statistics on turtle trade were also used as complementary information. We interviewed local residents who were exposed (n ¼ 50) and not exposed (n ¼ 50) to turtle conservation initiatives. When evaluating the two focal turtle species, we found differences in direct use between people exposed and not exposed to conservation programs, where people exposed to conservation initiatives made less direct use of these focal species. However, when other sympatric turtle species were considered, there were no significant differences in levels of turtle exploitation between people exposed and not exposed to conservation programs. Thus, successfully reducing the consumption of a focal turtle species might lead to an increased use of other local turtle species. Almost all interviewed locals were aware of turtle population declines, with the perceived most serious risk to turtle species reported being habitat loss and degradation followed by human consumption. Regarding turtle trade, we did not find significant differences between the two groups. Illegal trade levels in 2010 were 6.5 greater compared to 2016. We propose several new directions for turtle management and conservation of these species.

“…We argue that future research on the already well-studied species would best be directed towards monitoring demographic tendencies and evaluating the effectiveness of existing or future management programs (Páez et al, 2015). We also hope the explosion of knowledge on Colombian freshwater turtle and tortoise species continues, including the trend of publishing more in indexed journals in English, but hopefully in a way that also includes more of the poorly-studied species (Morales-Betancourt et al, 2015b;Forero-Medina et al, 2016), especially those that lack IUCN conservation status categorization (being listed currently as Data Deficient).…”

The citations contained in a recent literature review on the freshwater turtle and tortoise species of Colombia were analyzed. Publishing rates on these species have been increasing exponentially since the 1950s, although many of the publications would not be detected using internet-based literature searches. The most common topics of publications were systematics and phylogeography, nesting ecology, and management. In the 1970s and 1980s, the rate of publishing on the ecology and genetics of Colombian populations lagged behind the rate of publishing on these topics for populations of Colombian freshwater turtle and tortoise species located in other countries, but currently the production of the two regions is comparable. Also, in other countries there were trends towards publishing more over time in English and in journals with higher impact factors, but these trends were not significant for publications on Colombian populations. In Colombia, a disproportionate number of studies have been published on large-bodied species that face conservation problems. We argue that future studies of already well-studied Colombian species should focus on evaluating the effectiveness of management programs, and priority also should be given to increasing our knowledge of the many poorly-studied species in the country, especially those currently classified by the IUCN as data deficient (DD).Keywords: knowledge, literature, meta-analysis, publications, Testudines. RESUMENAnalizamos las referencias incluidas en una reciente revisión literaria sobre el estado de conocimiento de las tortugas continentales de Colombia. La tasa de publicaciones sobre estas especies ha incrementado exponencialmente desde los años 1950s, aunque muchas de éstas no podrían haber sido detectadas usando búsquedas de literatura por internet. Los tópicos más comunes de las publicaciones fueron sistemática y filo-geografía, ecología de anidación, y manejo. En los años 1970s y 1980s, la tasa de publicaciones sobre temas de ecología y genética de poblaciones ocupando el territorio colombiano, estuvo por debajo de publicaciones sobre estos dos tópicos con poblaciones de las mismas especies en otras regiones de Suramérica. Sin embargo, actualmente la producción en ambas regiones es comparable. En otros países, detectamos una tendencia temporal significativa de publicar cada vez más en inglés y en revistas de mayor impacto; esta tendencia no fue significativa para las publicaciones sobre poblaciones de tortugas colombianas. En Colombia, un número desproporcionado de las publicaciones son sobre especies de tamaños grandes que enfrentan problemas de conservación. Argumentamos que estudios futuros de las especies de tortugas continentales de Colombia relativamente bien conocidas, se deberían enfocar en evaluar la efectividad de los programas de manejo, y también debemos dar prioridad a investigaciones que aumenten el estado de conocimiento de las especies de tortugas continentales poco estudiadas en el país, especialmente de aquellas que actualmente están cat...

Approximately 356 species of turtles inhabit saltwater and freshwater habitats globally, except in Antarctica. Twenty-four species of turtles have been reported in Malaysia, four of which are sea turtles. The state of Terengganu harbored the highest number of turtles, with 17 different reported species. Based on the IUCN Red List, 29% of turtle species in Malaysia are critically endangered. In comparison, another 25% are classified as endangered. Likewise, CITES reported that 67% of Malaysia’s turtles are threatened, while 25% are classified as critically endangered. This review discusses the checklists, molecular genetics work, conservation status, recent trends, and recommendations for future research. Factors contributing to their population declines and current endangered status are also discussed.
