Fragmentation and Alteration of Seed Dispersal Processes: An Initial Evaluation of Dung Beetles, Seed Fate, and Seedling Diversity1
Given current accelerated trends of tropical land conversion, forest fragments are being incorporated into many conservation programs. For investing in fragments to be a viable conservation strategy, forest fragments must maintain their ecological integrity over the long term. Based on fieldwork in 22 forest fragments in the crater lakes region of western Uganda and in the continuous forest of ...
متن کاملSeed mass, seedling size and neotropical tree seedling establishment
1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...
متن کاملSeed storage oil mobilization is important but not essential for germination or seedling establishment in Arabidopsis.
Triacylglycerol (TAG) is a major storage reserve in many plant seeds. We previously identified a TAG lipase mutant called sugar-dependent1 (sdp1) that is impaired in TAG hydrolysis following Arabidopsis (Arabidopsis thaliana) seed germination (Eastmond, 2006). The aim of this study was to identify additional lipases that account for the residual TAG hydrolysis observed in sdp1. Mutants were iso...
متن کاملEffect of Seed Storage Duration and Seedling Raising method on Chamomile Seedling Establishment
Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...
متن کاملSEED DISPERSAL BY RED-RUFFED LEMURS: SEED SIzE, VIABILITY, AND BENEFICIAL EFFECT ON SEEDLING GROwTH
Frugivorous vertebrates play a critical role as seed dispersers of many tropical fruiting plants. In Madagascar, lemurs are the principal dispersers of fruit-bearing plants. This study aims to highlight the potential ecological role of the redruffed lemur (Varecia rubra) in the regeneration of a degraded forest, based on the quantity and size of passed seeds, their viability and germination, an...
