the aim of this study was to investigate the effect of reforestation on physical and chemical soil properties particularly soil carbon storage in the berenjastanak forest. forestations were including acer velotinum boiss., fraxinus excelsior l., populus nigra l. and pinus brutia ten. a witness forest with mixed species was selected as region potential. four soil profiles were drilled in each fo...
Gene flow dynamics of common ash (Fraxinus excelsior L.) is affected by several human activities in Central Europe, including habitat fragmentation, agroforestry expansion, controlled and uncontrolled transfer of reproductive material, and a recently introduced emerging infectious disease, ash dieback, caused by Hymenoscyphus fraxineus. Habitat fragmentation may alter genetic connectivity and e...
Long-Term Effect of an Aqueous Fraxinus excelsior L. Seed Extract in Spontaneously Hypertensive Rats
The effect of long-term intake of different doses (20, 40, and 60 mg/kg/day) of a Fraxinus excelsior L. seed extract (FESE) on spontaneously hypertensive rats (SHR) was evaluated. Water was used as control and captopril (50 mg/kg/day) was used as positive control. Systolic blood pressure, body weight, and food and liquid intake were registered weekly in SHR. The antioxidant and vascular relaxin...
We tested which factors explain the distribution pattern of the epiphytic moss Neckera pennata on three spatial scales using the framework of generalized linear models. First, we tested which factors explained its occurrence in forest stands in a 2500 ha landscape. At this scale, we also tested the effect of the historic landscape structure. We recorded its occurrence in all suitable stands. Th...
Abstract Common ash ( Fraxinus excelsior L.) is an economically and ecologically important tree species in Europe acutely threatened by dieback. Here, we present a new set of Simple Sequence Repeat markers for F. six related based on published silico designed primers. Forty SSR markers, mainly from genic regions, were tested amplification polymorphism characterized two populations Germany. Tran...
Non-native plant pests and pathogens are increasing exponentially, causing extirpation of foundation species. The impact large-scale declines in a single host on associated biodiversity is widely documented. However, the multiple loss whether these impacts multiplicative has not been assessed. Ecological theory suggests that systems with greater functional redundancy (alternative hosts) will be...
