We highlight hitherto unreported populations of two globally threatened phalangerid species on south-east Sulawesi’s offshore islands – bear cuscus (Ailurops ursinus) and small Sulawesi cuscus (Strigocuscus celebensis) – and observations of a third range-restricted species – Peleng cuscus (Strigocuscus pelengensis). Our data are based on records made during 11 years of seasonal surveys on Buton, and short-term expeditions to Kabaena and Manui. Our observations of S. celebensis on Buton, where it occurs in three protected areas, represent an important range extension for this species, as do our observations of A. ursinus on Kabaena, where it is also widespread. We also report the unexpected presence of S. pelengensis on Manui. Buton, in particular, appears to be an important stronghold for both A. ursinus and S. celebensis, given that forest ecosystems here remain extensive and relatively intact. Both these species may also display a previously unreported adaptability to disturbed forest and even some non-forest habitats within our study area. Hunting pressures, a proven threat to these species in northern Sulawesi, may also be lesser here.

Understanding the stoichiometric traits of plants is critical for studying their ecological adaptation strategies. Facultative epiphytes (which can also live on the ground) are an important component of epiphytic flora of montane forest ecosystems. However, a key gap persists in our understanding how facultative epiphytes can adapt different nutritional conditions of ground and canopy habitats? To study adaptive strategies of facultative epiphytes and the characteristics of the content and stoichiometric homeostasis of C, N, and P elements, we conducted a field experiment and a greenhouse N and P additions cultivation experiment. We found that epiphytic individuals of facultative epiphytes showed lower C:N and C:P ratios, higher variation in elemental composition, and more pronounced N limitation than terrestrial individuals. Moreover, facultative epiphytes showed strong control over the elemental composition of leaves, and their stoichiometric homeostasis of leaves and stems were stronger than roots. Furthermore, the homeostasis of facultative epiphytes decreased in the order N > P. Our results indicated that epiphytic and terrestrial individuals of facultative epiphytes have difference in nutrient limitation, and they use plastic strategies in different habitats. Epiphytic individuals survive in the intermittent habitat through luxury consumption of nutrient while terrestrial individuals were relatively conservative nutrient users. Furthermore, our results implied that facultative epiphytes maintain stable metabolic leaf activity via variable element concentrations of roots to adapt to highly heterogeneous forest habitats.

The Impact

High-frequency disturbance forest ecosystems undergo complex and frequent changes at various spatiotemporal scales owing to natural and anthropogenic factors. Effectively capturing the characteristics of these spatiotemporal changes from satellite image time series is a powerful and practical means for determining their causes and predicting their trends. Herein, we combined the spatiotemporal cube and vegetation indices to develop the improved spatiotemporal cube (IST-cube) model. We used this to acquire the spatiotemporal dynamics of forest ecosystems from 1987 to 2020 in the study area and then classified it into four spatiotemporal scales. The results showed that the cube-core only exists in the increasing IST-cubes, which are distributed in residential areas and forests. The length of the IST-cube implies the duration of triggers. Human activities result in long-term small-scope IST-cubes, and the impact in the vicinity of residential areas is increasing while there is no change within. Meteorological disasters cause short-term, large scope, and irregular impacts. Land use type change causes short-term small scope IST-cubes and a regular impact. Overall, we report the robustness and strength of the IST-cube model in capturing spatiotemporal changes in forest ecosystems, providing a novel method to examine complex changes in forest ecosystems via remote sensing.

Forest fires constitute widespread and potentially destructive disturbances in forest ecosystems, particularly negative impact on soil mycorrhizal fungi which are major players of the belowground plant. This study investigated the short-term effects of wildfire on fungal communities in Left-Bank Ukraine with special emphasis on mycorrhizal fungi. During the fourteen months after autumn wildfire, fruiting bodies found in the plots were identified, and their mycological richness, diversity and production in both burned and unburnt areas were measured. Total fungal diversity decreased in burned plots, where fungal richness and diversity of mycorrhizal species were significantly lower. Our results also confirmed the data on a rather destructive influence of post-fire forest management on fungal diversity. Only three mycorrhizal fungi associated with Pinus sylvestris L. were common to both sites while pyrophilic species were in close association with burned sites. 3 Figs., 1 Table, 31 Refs.

We provide a list of amphibian and squamate species collected in the Raso da Catarina Ecological Station, Bahia state, Brazil, during two distinct periods. An initial visual inventory of amphibians was conducted monthly from March 2010 to February 2011, using transects in a forest and temporary ponds. The second inventory was conducted over a 30-day period between March and April, 2012, when 37 pitfall trap arrays, each consisting of four buckets and supplementary glue traps, were set in low scrub and forest, complemented by opportunistic searches. A total of 19 lizard species, two amphisbaenians, 21 frogs, and 11 snakes were recorded during the study. New records for the protected area include 10 lizards, one amphisbaenian, 15 amphibians, and 11 snakes (36 species in total). Several species typical of the Atlantic Forest were collected, reflecting the potential influence of this biome, especially in the sampled forest habitats (Mata da Pororoca).

AbstractAssessments of conservation status are usually carried out on a global scale but national priorities often necessitate a more focused approach. Using a typology of rarity first articulated in the early 1980s by Deborah Rabinowitz, coupled with presence/absence from protected areas, preliminary conservation status at the national level was assessed for 397 species of ferns and fern allies from El Salvador in Central America. Of these, 43 lacked sufficient data, 175 were considered not of conservation concern, 106 were considered to be at risk and 73 to be threatened. The majority of the threatened species were from cloud or montane forest habitats but aquatics and species restricted to pine–oak forests are also rare and occur outside protected areas. The utility of this simple methodology is discussed and the importance of field studies by local experts with local knowledge emphasized.
