“…Further, given the marbled cat's avoidance of degraded forests (including edges and fragmented forests) and inability to adapt to oil palm landscapes, a population decline of more than 30% over the last 10‐year period can be reasonably suspected. These threats have not ceased (Estoque et al, 2019; Grantham et al, 2020; Sasaki et al, 2021; Wilcove et al, 2013) so the marbled cat likely meets the requirements to be classified as Vulnerable under criterion A2 subsection C of the IUCN RL categories criteria (IUCN Standards and Petitions Committee, 2019). Conserving and increasing the connectivity of large intact forests is a priority for marbled cat conservation.…”

Marbled cats in Southeast Asia: Are diurnal and semi‐arboreal felids at greater risk from human disturbances?

Southeast Asia supports the greatest diversity of felids globally, but this diversity is threatened by the severe forest loss and degradation occurring in the region. The response of felids to disturbances appears to differ depending on their ecology. For example, the largely terrestrial and nocturnal leopard cat (Prionailurus bengalensis) thrives near forest edges and in oil palm plantations where it hunts rodents (Muridae) at night, thereby avoiding human activity peaks. Conversely, we hypothesized that the sympatric and similar-sized marbled cat (Pardofelis marmorata) would respond negatively to edges and relatively open oil palm plantations as they are more arboreal than leopard cats, rely on tree connectivity for hunting, and are diurnal so have less potential to temporally avoid humans. We used camera trapping from Southeast Asia to test habitat associations at multiple spatial scales using zero-inflated Poisson generalized linear mixed models and hierarchical occupancy modeling. We found that marbled cats were positively associated with large intact forests and, in contrast to leopard cats, negatively associated with oil palm plantations. Furthermore, we found preliminary evidence suggesting marbled cats may adapt their diel activity to become more crepuscular in degraded forests, likely shifting their activity to avoid humans. These findings suggest that the marbled cat's International Union for Conservation of Nature (IUCN) Red List conservation status should potentially be upgraded from Near Threatened to Vulnerable, matching other forest-dependent felids in the region. We posit our findings may be generalizable such that semi-arboreal and diurnal felids could face greater threats from habitat degradation than their terrestrial and nocturnal relatives.

“…The conversion of cropland to forest increased carbon storage by 0.42 Tg; the conversion of wetland and water to forest was minimal, resulting in very limited reduction and increase in carbon storage, respectively; built-up land area was in continuous high expansion, and grassland was mainly converted to built-up land and cropland, so they did not produce a conversion to forest, resulting in no gain or loss of carbon storage (Table 5). Unlike tropical regions such as South America, Southeast Asia, and central Africa, where the reduction in carbon storage is due to the shrinking of forest areas [75][76][77][78][79], the change in carbon storage due to the change in forest on Hainan Island is positive, and even though some of the increase in carbon storage is offset by the reduction in carbon storage due to the transfer out of cropland, a small increase in carbon storage can still be maintained. From 1992 to 2019, the decrease in LULC carbon storage on Hainan Island caused by the continuous increase in built-up land area was 3.24 Tg, the absolute amount of change being greater than the absolute amount of change in carbon storage caused by the decrease in cropland or the increase in forest, and is the most critical aspect of carbon storage change on Hainan Island (Table 6).…”

“…The shrinking of forest in northern Brazil is widely known, so an ecological conservation development pattern will help increase carbon storage in this region [77]. Although contradictory to improving local living standards, the implementation of appropriate ecological protection policies in central Africa and Southeast Asia [79] can promote carbon storage. Even in temperate regions, such as China's Loess Plateau [55] and northwest desert regions [54], ecological conservation policies that promote the growth of forest and grassland areas can maximize carbon storage.…”

Land use and land cover (LULC) change in tropical regions can cause huge amounts of carbon loss and storage, thus significantly affecting the global climate. Due to the differences in natural and social conditions between regions, it is necessary to explore the correlation mechanism between LULC and carbon storage changes in tropical regions from a broader geographical perspective. This paper takes Hainan Island as the research object, through the integration of the CA-Markov and Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) models, based on multi-source data, analyses the dynamics of LULC and carbon storage from 1992 to 2019 and the relationship between the two, and predicts future LULC and carbon storage under different scenarios. The results show that (1) the built-up land area of Hainan Island expanded from 103.59 km2 to 574.83 km2 from 1992 to 2019, an increase of 454.91%; the area of cropland and shrubland decreased; and the area of forest increased. (2) Carbon storage showed an upward trend during 1992–2000, and a downward trend during 2000–2019. Overall, LULC changes during 1992–2019 reduced carbon storage by about 1.50 Tg. (3) The encroachment of cropland in built-up land areas is the main reason for the reduction of carbon storage. The conversion of shrubland to forest is the main driving force for increasing carbon storage. The increase and decrease of carbon storage have obvious spatial clustering characteristics. (4) In the simulation prediction, the natural trend scenario (NT), built-up land priority scenario (BP) and ecological priority scenario (EP) reduce the carbon storage of Hainan Island, and the rate of decrease is BP> NT > EP. The cropland priority scenario (CP) can increase the LULC carbon storage, and the maximum increase in 2050 can reach 0.79 Tg. This paper supplements and improves the understanding of the correlation between LULC and carbon storage changes in tropical regions, and can provide guidance for the optimization of LULC structure in tropical regions with high economic development from a low-carbon perspective.

“…However, the dynamic of ecosystem services in the deep soil may be different from those in the surface layer. In addition, spatial analysis can be carried out from the perspective of landscape to evaluate the spatio-temporal changes in different forest types and the evolution of ecosystem services [52,53], thus providing support for forest management.…”

The transition from natural forest to plantations has increased dramatically in the past decades. Forest conversion will affect soil properties and thus soil ecosystem services. Based on soil indicators, we studied the differences of soil ecosystem services among three forest types in Liuxihe National Forest Park and analyzed the effects of conversion from natural forest to artificial forest on soil ecosystem services. The results showed that the soil carbon sequestration of evergreen broadleaf forest (EBF) was stronger, and the soil organic carbon density (36.43 ± 0.97 kg m−3) was significantly higher than that of moso bamboo forest (MBF) (25.46 ± 1.72 kg m−3) and sugar orange forest (SOF) (19.31 ± 2.68 kg m−3) in the 0–10 cm soil layer. The soil water conservation of MBF was higher, and its soil water content was significantly higher than that of EBF in the three soil layers, which was more than 20% higher than that of EBF. There was no significant difference in soil total nitrogen content among the three forest types, while the soil total phosphorus content of MBF and SOF was more than twice that of EBF. It is important to consider soil ecosystem services in forest protection and restoration in forest parks.
