ABSTRACT
Litter decomposition is vital for carbon and nutrient turnover in
terrestrial ecosystems, and this process has now been thoroughly demonstrated
to be regulated by various mechanisms. The total environment has been
continuously changing in recent decades, especially in high-latitude regions;
these alterations, however, profoundly contribute to the decomposition process,
but a comprehensive recognition has not available. Here we reviewed the
empirical observations and current knowledge regarding how hydrological
leaching and freeze-thaw events modulate early decomposition of plant litter.
Leaching contributes a considerable percentage of mass loss and carbon and
nutrient release in early stage of decomposition, but the magnitudes are
different between species levels depending on the chemical traits. Frequent
freezing and thawing events could positively influence decomposition rate in
cold biomes but also hamper soil decomposer and there is no general and
predictable pattern has been emerged. Further experiments should be manipulated
to estimate how the altered freezing and thawing effect on carbon and nutrient
release from plant litter to better understanding the changing environment on
litter decomposition.
Keywords: cold biomes; freeze-thaw; leaching; litter decomposition
ABSTRAK
Penguraian sampah adalah penting untuk pusing ganti karbon dan
nutrien dalam ekosistem daratan dan proses ini kini telah dibuktikan secara
terperinci dikawal oleh pelbagai mekanisme. Persekitaran secara keseluruhan
berterusan berubah sejak beberapa dekad kebelakangan ini terutamanya di kawasan
berlatitud tinggi; perubahan ini, walau bagaimanapun menyumbang secara mendalam
kepada proses penguraian, tetapi tidak terdapat suatu pengiktirafan yang
komprehensif. Di sini kami mengkaji cerapan empirik dan pengetahuan semasa
tentang bagaimana kejadian hidrologi larut lesap dan beku-cair memodulatkan
proses awal pereputan sampah loji. Larut lesap menyumbang kepada peratusan
kehilangan jisim dan karbon serta pelepasan nutrien yang agak besar pada
peringkat awal pereputan, tetapi magnitud tersebut berbeza antara tahap spesies
bergantung kepada sifat kimia. Kekerapan kejadian larut lesap dan beku-cair
boleh secara positif mempengaruhi kadar penguraian dalam biom sejuk tetapi juga
menghalang tanah diurai serta tidak terdapat pola umum dan boleh diramal yang
muncul. Uji kaji susulan harus dimanipulasi untuk menganggarkan bagaimanakah
kesan pengubahsuaian larut lesap dan beku-cair ke atas pembebasan karbon dan
nutrien dari loji sampah untuk memahami dengan lebih baik persekitaran yang
berubah-ubah kepada penguraian sampah.
