Experiences from the field

My fieldwork started in 2007. I have managed "and co-managed" dozen international scientific expeditions to New Guinea by involving more than 100 participants originated from 8 countries, 21 disciplines, >20 universities and research institutions. Since 2007, we have explored  more than 50% of surface plus underground water system of the Bird's Head and neck of Papuan Peninsula (Western part of New Guinea). 

 
 
 

New Guinean Rainbowfishes

Duration: 2007-2020
Project Leaders: Kadarusman PhD & Laurent Pouyaud PhD 

New Guinea is the world second large island after Greenland, covered by 70% rainforest and believed to home about 10% of the world biodiversity. Politically, The New Guinea is divided into two part, Eastern part is the state of Papua New Guinea while the western part is composed by two Indonesian provinces, Papua and Papua Barat. The western part of New Guinea is home >50% of the total Indonesian biodiversity. Currently, western New Guinea harbours >60% of the member Melanotaenids discovered. Rainbow fishes belongs to Melanotaenoidei composing three families, Bedotiidae is confined in Madagascar, Melanotaeniidae has distribution to Australia, New Guinea and surrounding island, whereas Pseudomugilidae spreads to wide range region, Sulawesi, New Guinea and Australia. The project aims at charaterizing the diversity of rainbow fishes by a couple approach, molecular and morphology analysis.


 

  

Lengguru-Kaimana

Duration: 2010-2020
Project Leaders: Kadarusman PhD, Gono Semiadi PhD & Laurent Pouyaud PhD, Dr. Irma Arlyza

The Lengguru Range is located in the Kaimana Regency (West Papua, Indonesia). It is characterized by series of parallels and oblique folds, with altitude ranging from 600 to 1500 m. These carbonate anticlines are separated by deep valleys sometimes closed and rifted with no outflow of collected water (i.e. endorheic). Lengguru’s topography consists of karsts limestone shaped by uplift or subsidence geologic events and under the dissolving action of water on carbonate bedrocks since a dozen of millions years (cc. 10-12 Myr.). This rough and fragmented landscape displays unusual surface and subsurface features including sinkholes, vertical shafts, lapies, loss-resurgence streams, complex underground systems and caves. These sedimentary outcrops are therefore characterized by a large array of ecological niches afforded by complex terrains and variable climatic conditions. Lengguru research project aims at studying the processes and the interactions between geodynamics and biodiversity in Papuan limestone karsts.


 

Catfishes and Palaemonids of New Guinea

Duration: 2014-2016
Project Leaders: Kadarusman PhD, A. Suhermanto & A. Sofian
 

A total species of freshwaterfishes in New Guinea counted less than 500 species, and  the most diverse family known, are Eleotridae and Gobiidae composing 115 species, following Melanotaeniidae >60 species. As the member of freshwater dweller, Papuan catfishes and giant prawn (Palaemonids) have widely distributed across the island, occupying all spectrum of freshwater bodies: river, swamp, lakes. Nevertheless, study on species diversity and phylogenetic relatedness are scarce, plus their taxonomy remains incomplete and somewhat confused.  The project aims at characterising their diversity by using the molecular and morphological analysis through systematical work. In order to standardize identification, we implement DNA-barcoding method (COI: >750 bp) and we amplify some markers to understand their biogeographical history. To integrate our scientific-work with the campus program for sustainable aquatic production, all live specimen caught during the fieldwork will be transported to domestication trial at iLitbangbiat-Poltek KP Campus West Papua. Since 2014, we have warm welcoming bachelor and master scholars from various universities, coming to our laboratory for studying this fascinating biota.
