“…This result is consistent with field observations reporting that incoming solar radiation leads to sparser vegetation cover on SFS than NFS (Bass et al, 2017;Broza et al, 2004;Del-Toro-Guerrero et al, 2016) and in agreement with previous modelling studies considering the effect of aspect under uniform precipitation (Caylor et al, 2004;Flores-Cervantes et al, 2014;Gutiérrez-Jurado et al, 2013;Hinckley et al, 2014;Srivastava et al, 2019;Yetemen, Istanbulluoglu, Flores-Cervantes, et al, 2015;Zou et al, 2007).…”

Topography affects the intensity and spatial distribution of precipitation due to orographic lifting mechanisms and, in turn, influences the prevailing climate and vegetation distribution. Previous modelling studies on the impact of orographic precipitation on landform evolution have considered bare soil conditions. However, research on the effect of changes in precipitation regimes induced by elevation gradients (particularly in aspect-controlled semi-arid ecosystems) on landform patterns, trying to understand feedbacks and consequences for coevolving vegetation, has been limited. In this study, the Channel-Hillslope Integrated Landscape Development (CHILD) landscape evolution model coupled with the vegetation dynamics Bucket Grassland Model (BGM) is used to analyse the coevolution of semi-arid landformvegetation ecosystems. The CHILD+BGM model is run under different combinations of precipitation and solar radiation settings. Three precipitation settings, including uniform, elevation control, and orographic control on precipitation, are considered in combination with spatially uniform and spatially varied radiation settings. Based on the results, elevation control, aspect, and drainage network are identified as the major drivers of the distribution of vegetation cover on the landscapes. Further, the combination of orographic precipitation and spatially varied solar radiation created the highest asymmetry in the landscape and divide migration due to the emergence of gentler slopes on the windward than the leeward sides of the domain. The modelling outcomes from this study indicate that aspect control of solar radiation in combination with orographic precipitation plays a key role in the generation of topographic asymmetry in semi-arid ecosystems.

“…Sebagai komponen ekosistem, Collembola mempunyai peran yang beraneka ragam antara lain pengendali penyakit tanaman akibat jamur, perombak bahan organik, penyeimbang ekosistem, indikator hayati tingkat kesuburan atau keadaan tanah dan pengurai bahan beracun (Suhardjono et al 2012). Rusek (1998) Penyebarannya menunjukkan kemampuan adaptasi terhadap habitat dan vegetasi yang berbeda (Broza et al 2004). Husamah et al (2016) melaporkan bahwa keanekaragaman Collembola di hutan lebih tinggi dibandingkan di lahan pertanian dan pemukiman.…”

Collembola merupakan kelompok Arthropoda yang sangat beragam dan memiliki fungsi penting di dalam ekosistem tanah. Namun, kelimpahan dan keanekaragaman Collembola di Kalimantan Barat masih sedikit dipelajari. Tujuan penelitian ini adalah untuk mendapatkan informasi kelimpahan dan keanekaragaman Collembola, serta hubungannya dengan faktor lingkungan. Sampel dikumpulkan pada Desember 2016 dan Februari 2017. Collembola dikumpulkan dari hutan alami, hutan karet, kebun kelapa sawit, ladang dan lahan marginal. Hasil penelitian diperoleh tiga ordo, 10 famili dan 26 genus dengan total 393 individu. Terdapat perbedaan pada kelimpahan dan keanekaragaman ordo, famili dan ge-nus pada lima ekosistem yang berbeda. Perbedaan faktor lingkungan berperan penting terhadap kelimpahan dan struktur komunitas Collembola. Berdasarkan indeks keanekaragaman, hutan alami memiliki keanekaragaman Collembola tertinggi (2,69), diikuti oleh hutan karet (2,44), kebun kelapa sawit (2,37), ladang (1,52) dan lahan marginal (0,56). Hasil analisis korelasi menunjukkan terdapat korelasi positif antara beberapa genus Collembola dengan C organik, N total dan C/N rasio.

“…Studies from the ecology, soil science, hydrology, and geomorphology communities have been conducted at different locations throughout the world to understand the implications of aspect-controlled ecosystems on vegetation type, density, biodiversity, and phenology (Broza et al, 2004;Caylor et al, 2004;Kirkpatrick & Nunez, 1980;Nobel & Linton, 1997); chemical composition of soils (Klemmedson & Wienhold, 1992;Román-Sánchez et al, 2018) and plants (Vetaas, 1992;Xu et al, 2017); soil moisture (Cantón et al, 2004;Geroy et al, 2011); runoff production, erosion, and resulting landscape form (Hinckley et al, 2014;Yetemen et al, 2015;Richardson et al, 2020); and wildfire risks (Calviño-Cancela et al, 2017;Walsh et al, 2017). These studies report that denser and mesic vegetation is usually dominant on PFS, while EFS are occupied by sparser and xeric plants in both the Northern Hemisphere (NH) (Nevo, 1995;Sternberg & Shoshany, 2001) and the Southern Hemisphere (SH) (Armesto & Martinez, 1978;Badano et al, 2005).…”

Our current understanding of semiarid ecosystems is that they tend to display higher vegetation greenness on polar‐facing slopes (PFS) than on equatorial‐facing slopes (EFS). However, recent studies have argued that higher vegetation greenness can occur on EFS during part of the year. To assess whether this seasonal reversal of aspect‐driven vegetation is a common occurrence, we conducted a global‐scale analysis of vegetation greenness on a monthly time scale over an 18‐year period (2000–2017). We examined the influence of climate seasonality on the normalized difference vegetation index (NDVI) values of PFS and EFS at 60 different catchments with aspect‐controlled vegetation located across all continents except Antarctica. Our results show that an overwhelming majority of sites (70%) display seasonal reversal, associated with transitions from water‐limited to energy‐limited conditions during wet winters. These findings highlight the need to consider seasonal variations of aspect‐driven vegetation patterns in ecohydrology, geomorphology, and Earth system models.
