“…Our results suggest that the Asian elephant and the rhinoceroses tended to move northward when temperature was high.

Our results are also consistent with the qualitative analysis by Wen and Wen (2006) that changes of northern boundaries of Asian elephant and the rhinoceroses might be associated with fl uctuations of temperature.…”

Many species have experienced dramatic declines over the past millennia due to the accelerated impact of human activity and climate change, but compelling evidence over such long‐term time scales is rare. China has a unique system archiving historical records of important social, meteorological, agricultural and biological events over the last three millennia. We derived historical species occurrences (0–2000 AD) based on a comprehensive review of literature. To detect the driving forces of range contraction, we used correlation and multiple regression to quantify the linear association between species range indices and climate variables (five temperature series and three precipitation series), as well as a human population size series. We also used a machine learning technique, random forest, to quantify the nonlinear effects of the climate variables and human population size. The southward retreat of the Asian elephant Elephas maximus and the rhinoceroses (Dicerorhinus sumatrensis, Rhinoceros unicornis, R. sondaicus) was closely associated with climate cooling and intensified human impact (represented by high population size), and the westward retreat of the giant panda Ailuropoda melanoleuca was associated with intensified human impact. One temperature series and human population size showed interactive effect on range shift of the Asian elephant and the rhinoceroses; the effect of temperature was positive at low population size, but negative at high population size. Our results imply that a higher temperature caused the northward or eastward range shift of the Asian elephant, the rhinoceroses and the giant panda, and currently this trend is impeded by human activities. We also illustrate how human activity and climate act synergistically to cause range contraction.

“…Within our study group, we further narrowed our case studies to one reptile and eight mammals. The selected taxa met the following criteria: they are listed as “endangered” or “critically endangered” by the IUCN in our region of study; they have a written and fossil record that is sufficient to assess past changes in range, as well as ecological and environmental preferences, and the reasons for their decline; and they have suffered massive geographical range restrictions since the late Pleistocene (for examples of range reduction maps, see Antoine ; Louys ). These organisms are spread across diverse taxonomic and ecological spectra and have the potential to be translocated within former ranges or to act as species substitutions for conservation and/or ecological restoration purposes (Fig.…”

“…Elephants and stegodons apparently coexisted over much of this range, although only stegodons inhabited the smaller islands. There were at least five species of proboscidean present in the late Pleistocene, but by the Holocene only the Asian elephant (Elephas maximus) survived, confined to mainland Asia, Sumatra and Java (Louys et al 2007;Louys 2012). Asian elephant distributions have become progressively restricted in the last two millennia.…”

Alarm over the prospects for survival of species in a rapidly changing world has encouraged discussion of translocation conservation strategies that move beyond the focus of ‘at-risk’ species. These approaches consider larger spatial and temporal scales than customary, with the aim of recreating functioning ecosystems through a combination of large-scale ecological restoration and species introductions. The term ‘rewilding’ has come to apply to this large-scale ecosystem restoration program. While reintroductions of species within their historical ranges have become standard conservation tools, introductions within known paleontological ranges—but outside historical ranges—are more controversial, as is the use of taxon substitutions for extinct species. Here, we consider possible conservation translocations for nine large-bodied taxa in tropical Asia-Pacific. We consider the entire spectrum of conservation translocation strategies as defined by the IUCN in addition to rewilding. The taxa considered are spread across diverse taxonomic and ecological spectra and all are listed as ‘endangered’ or ‘critically endangered’ by the IUCN in our region of study. They all have a written and fossil record that is sufficient to assess past changes in range, as well as ecological and environmental preferences, and the reasons for their decline, and they have all suffered massive range restrictions since the late Pleistocene. General principles, problems, and benefits of translocation strategies are reviewed as case studies. These allowed us to develop a conservation translocation matrix, with taxa scored for risk, benefit, and feasibility. Comparisons between taxa across this matrix indicated that orangutans, tapirs, Tasmanian devils, and perhaps tortoises are the most viable taxa for translocations. However, overall the case studies revealed a need for more data and research for all taxa, and their ecological and environmental needs. Rewilding the Asian-Pacific tropics remains a controversial conservation strategy, and would be difficult in what is largely a highly fragmented area geographically.

“…This fossil evidence emphasizes the need to address the evolutionary issues of niche differentiation and competition between these three caprine taxa through space and time, and to understand better the past ecological factors driving the distribution patterns of their modern populations. Moreover, the understanding of the diet and habitat use of these sympatric species is crucial, not only for improving our knowledge on the refugial hypothesis but also to achieve more effective and efficient conservation plan of the species for the future, as it is currently implemented for other endangered species (e.g., Birks, 2012;Louys, 2012;Archer et al, 2019). Among several ecological approaches, stable isotope tracking on tooth enamel is recognized as a powerful tool for exploring several aspects of the life history of living and fossil animals.…”

Long-Term Isotope Evidence on the Diet and Habitat Breadth of Pleistocene to Holocene Caprines in Thailand: Implications for the Extirpation and Conservation of Himalayan Gorals

Paleoecology of Southeast Asian Caprines human impacts on Thai ecosystems. In addition to the loss or reduction of grasslands after the latest Pleistocene when rainforests became dominant and besides the human hunting and predation pressure, the high interspecific competition likely contributed to the extirpation of Himalayan gorals in Thailand. Developing a strategic plan for the future biodiversity conservation, a long-term historical isotope approach allowed us to predict the contrasting habitat suitability, a lowland grassland, for these two threatened goral species as testified by their ecological persistence during the Pleistocene.
