Margit Smelt: The Effect Of Saltwater Intrusion On Terrestrial Vegetation In Village Forest Gardens On The Northeast Coast of Java and Its Socio-Economic Consequences

Wageningen Universiteit & Research

Village forest gardens  are special types of gardens with layers of shrubs, bamboos, palms, and trees around homes. These gardens provide a variety of things like fuel, building materials, fruits, food, and even medicine. In places like southeast Asia, these gardens are a tradition and a symbol of sustainability. Village forest gardens also solve problems like land damage, loss of forests, and lack of energy in rural areas. They are vital for a community’s health, jobs, economy, food, and the environment. This study presents information on the effects of saltwater intrusion on the composition , land usage and growth characteristics of terrestrial vegetation in village forest gardens at Java’s Northeast coast and its socio-economic consequences.

It was concluded that the extent of saltwater intrusion in village gardens decreases moving away from the coast to land inwards. Tidal floods are increasing in frequency in this area and affecting livelihoods that are facing land subsidence, coastal erosion and saltwater intrusion. The study indicates that village gardens in coastal livelihoods play an important role in sustaining the biodiversity of relevant economic relevant food source species like Jambu air (Syzygium aqueum), mango (Mangifera indica) and banana (Musa paradisiaca). However, Jambu air and mango showed significance differences in abundance between low and high saline environments indicating the threat of saltwater intrusion to these crops. I am grateful for all the experiences and wonderful people I have met during my time in Indonesia, I could not have done my thesis without them.

Ruben ter Harmsel: The History and Current Floristic and Abiotic State of Dutch Calcareous Grasslands

Radboud Universiteit

Dutch calcareous grassland is a rare, semi-natural, species rich habitat type, protected by EU law. Understanding which factors influence its floristic composition could help conservation and restoration efforts. To research this, I made vegetation relevés and took soil samples across calcareous grasslands in Southern Limburg. I also collected historical vegetation data. My research showed that areas have their own floristic and abiotic identity, and that this identity has been present during the past century. I found that the current differences in floristic composition could not be directly explained by current differences in size, exposition, inclination, or type of management of an area. I found that the levels of nitrate and ammonium in the soil could be related to the current floristic composition of calcareous grasslands, but only slightly. I also found that there have been large changes in floristic composition in the last century on a habitat-level and on an area-specific level. Because of the uniqueness of each area, a sustainable conservation-strategy should focus on conserving and increasing habitat quality of areas, as well as on increasing the total surface area and connecting existing areas. Furthermore, species-specific interventions are needed to prevent more local extinctions of rare species. (Foto: l. Ruben ter Harmsel, r. Wiene Bakker)

Maarten van Emmerik: Effect of Urban Heat Island on Germination of Common Dandelion

Radboud University

During this MSc internship, I studied urban dandelions in Amsterdam, Nijmegen, and Maastricht. The aim was to investigate adaptation to the Urban Heat Island (UHI) effect. This effect causes overheating of stony areas due to heat retention during sunny days. I sampled plants from the hot city center and compared these to plants in surrounding rural areas. To investigate adaptation, I first conducted germination experiments in climate chambers. And I sequenced heat resistance genes of a selection of different genotypes samples along urban-rural transects. I discovered that seed weight had a positive correlation with germination speed and -success. A gene lineage tree based on sequence diversity showed that clonal lineages on streets are nested within lineages from rural areas, indicating repeated colonization of the UHI by dandelions from outside cities. Of the 34 genes analyzed, a total of 5 genes showed fixation to certain nucleotides in city center plants, possibly due to adaptation to the UHI. In short, my internship indicated that urban dandelions adapt to the UHI but at what speed is not yet known.

Lucas Chojnacki: Shaping Tropical Forests

Wageningen University & Research

Secondary forests, most often regenerating from abandoned lands, offer insights into post-disturbance recovery. Succession, the dynamic process of change in forest structure and composition, is influenced by various factors. Understanding the role of dominant and rare species in driving forest attributes is essential is for estimating restorative potential of secondary forests. To do so, our research capitalizes on a unique experiment applying distinct harvest treatments to dominant and rare species in young secondary forests in Ghana. We found striking dominance of a few species in or forest plots. They significantly characterize forest structure and composition at early successional stage. Removing are species induced the largest changes in forest structural attributes, tree diversity, functional trait and microclimatic conditions as rare species are the main sources of heterogeneity at the start of succession. The dominant species displayed some acquisitive traits, typical of pioneer species, but also some conservative traits which are probably linked to investment in leaf longevity. The removal or rare species affected microclimatic conditions in the forest understory the most, emphasizing the crucial role of rare species in modulating light availability. The extent of recovery in forest attribute is predominantly defined by the structural and compositional legacy of the treatments.

Fabiënne de Jager: The effect of stressors on the onset of pneumatophore development of black mangroves

Wageningen University & Research

For my Master Thesis I went to Semarang to study the effects of flooding events on the Avicennia mangrove species in the Demak Regency (Timbulsloko). Seawater with a high salinity (30 ppt) flows further into the estuaries and rivers, which causes salinity concentrations in aquifers, aquaculture ponds and in ground water. Pneumatophores act as mechanical barrier and reduce the speed of the waves coming from storm surges during rain season (November till March) or during spring tides (mostly occurring in May-June). Therefore, the need of maintaining and rebuilding these mangroves are crucial for coastal protection. Mangroves are the most important plant species in this area to protect the coastal villages around Timbulsloko. I mainly found two Avicennia species in the area; Avicennia marina and Avicennia alba. These species are recognizable by their aerial roots which grow above the sediment to catch extra oxygen from the air. This happens when the soil conditions are anoxic. My hypothesis is that salinity and sediment type is also a stimulating factor for pneumatophore growth. Results showed that salinity of the surface water did have a significant effect on the pneumatophore growth of the mangroves. The other variables didn’t seem to have an effect on the pneumatophores. This could be due to the big differences in sites and trees during the sampling and the wide variance of the data.

In short during this field research I gained a lot of knowledge about mangroves and the species differences, which I can take with me in the future.

Xenia Davide: Effects of Temperature and Rainfall on Stem Growth in the Tropical Tree Species Toona ciliata

Maastricht University and Wageningen University

Tropical forests are essential to the regulation of climate and the global carbon cycle. They account for a third of global primary productivity, drive fluctuations in the terrestrial land sink, and thus have the potential to influence the pace of climate change. Multiple investigations revealed declining tree growth rates and forest productivity, making it increasingly important to comprehend how climate variability, particularly temperature and rainfall patterns, affects tropical trees. Both rainfall and maximum temperature have been found to be crucial factors in influencing stem growth. The predicted increase in climate change-related variability also increases the necessity of understanding tree growth responses. Despite their critical function, there is currently an absence of comprehensive understanding of tropical tree physiological and growth responses to climate variability.
With this project, I aim to bridge this gap by analysing samples of Toona ciliata, a tropical tree that was shown to make tree rings, with standard dendrochronological methodology. The samples were collected in multiple locations in the wet tropics world heritage, Queensland, Australia. By doing so, I want to provide new insights into the effects of climate on the growth and physiology of this species in the region.
