Distribution of vegetation in present day wetlands - some applications in geoscience

Upload by Logic

Wetland vegetation forms diverse habitats that host varied flora and fauna, ranging from freshwater swamp, mangrove, Nipa swamp, and peat swamp to peat-limited regions across Malaysia and Borneo. Many wetland plants survive harsh, waterlogged substrates through special adaptive mechanisms, including breathing roots and strategies to reduce excessive salinity while ensuring successful seed propagation. The study links fossil pollen records preserved in fine-grained rocks to reconstruct past vegetation history and addresses brief applications of wetland-derived pollen data in geoscience.

INTRODUCTION

ADAPTIVE MECHANISMS IN WETLAND VEGETATION

PAST RECORDS OF WETLANDS

# Distribution of vegetation in present day wetlands:some applications in geoscience Wetlands have important natural functions such as regulating flood flow,supply of water to reservoirs during dryseason,filter pollutants from air and water,and breeding grounds for some marine live.Some wetland plants producelarge quantities of pollen that become well preserved in fine-grained rocks.In this manner,the records of past vegetationhistory may be uncovered by retrieving the fossil pollen from the rocks.Based on these principles,records of fossilpollen have often been used to solve certain stratigraphic and geological issues. Abstrak:Kawasan tumbuhan paya merangkumi beberapa habitat unik yang menjadi perumah kepada pelbagai flora dannfauna.Di rantau ini,beberapa habitat yang biasa ditemui adalah seperti paya air tawar,paya bakau,paya nipah dan payagambut.Sesetengah tumbuh-tumbuhan ini telah mengalami perubahan adaptasi(penyesuaian)seperti sistem pernafasanakar yang khusus,sistem untuk mengurangkan lebihan garam/kemasinan dan mekanisme yang menjamin kejayaanpembiakan biji benih. Kawasan paya memainkan fungsi semulajadi yang penting seperti mengawal aliran banjir,menjadi sumber air bagitakungan ketika musim kering,menapis bahan cemar dari air dan udara dan menjadi tempat pembiakan untuk sebahagianhidupan laut.Terdapat tumbuh-tumbuhan kawasan paya ini yang menghasilkan sejumlah debunga yang terawet di dalambatuan berbutir halus.Dengan itu,rekod mengenai sejarah tumbuh-tumbuhan masa lampau dapat diketahui denganmemperolehi fosil debunga dari batuan tersebut.Berdasarkan kepada prinsip-prinsip ini,rekod fosil debunga kerap kalidigunakan untuk menyelesaikan isu-isu stratigrafi dan geologi. Kajian ini bertujuan untuk menunjukkan taburan tumbuhan dan rekod debunga dari beberapa habitat kawasan payamasa kini yang terdapat di Malaysia dan Borneo.Beberapa kegunaan/aplikasi dalam geosains hasil dari fosil debungakawasan paya juga dibincangkan secara ringkas. ## INTRODUCTION Wetlands are habitats that are primarily controlled byfluctuation of water level.The water in wetlands can eitherbe freshwater or brackish and flowing or static.In Malaysia,wetlands comprised mainly of freshwater swamp,peatswamp,mangrove and Nipa swamp.Freshwater swamps(Paya air tawar)can be found in the upper reach of SungaiSedili,Johor and in Tasek Bera and Tasek Cini in Pahang.Peat swamp(Paya gambut)is now limited to certain partsof Johor,Selangor and Perak.Large areas of peat swampcan still be seen in Sarawak and the Klias Peninsular inSabah.640,000 ha of Mangrove swamp(Hutan paya laut)exists in Malaysia,half of which is in Sabah.Nipa swampoccupies the area immediately behind the mangrove,oftenlining the tidal reaches of rivers.It is less extensive thanmangrove. Wetlands are important ecosystems for several reasons.For instance,during the wet season,a large volume ofwater can be stored in the wetland system to be released to AZMI MOHD YAKZAN PETRONAS Research &Scientific Services Sdn.Bhd.Bangi,Selangor Abstract:Wetland vegetation occupies several unique habitats that are host for diverse flora and fauna.In this region,some of the common wetland habitats are freshwater swamp,mangrove,Nipa swamp and peat swamp.Some plants haveedeveloped adaptation such as special breathing root systems,a means to reduce excessive salinity,and mechanism toensure successful propagation of young seedlings,to name a few.

FAQs

What habitats are covered under wetland vegetation in this work?

The paper focuses on freshwater swamp, mangrove, Nipa swamp, and peat swamp habitats, including examples found across Malaysia and Borneo.

Why are wetland plants able to survive in waterlogged environments?

Wetland plants develop adaptations such as breathing root systems for low-oxygen substrates, mechanisms to reduce excessive salinity, and reproductive strategies that support successful seed propagation.

How do fossil pollen records help in geoscience studies?

Fossil pollen preserved in fine-grained rocks can be retrieved to uncover past vegetation history and support solutions to stratigraphic and geological issues.
