Seed Dispersal: The Blind Bomb Maker
نویسنده
چکیده
A recent study shows that a desert shrub uses a 'mustard oil bomb' to regulate the behaviour of seed-predating rodents - transforming these predators into mutualistic seed dispersers.

Intraspecific Directed Deterrence by the Mustard Oil Bomb in a Desert Plant
Plant secondary metabolites (SMs) acting as defensive chemicals in reproductive organs such as fruit tissues play roles in both mutualistic and antagonistic interactions between plants and seed dispersers/predators. The directed-deterrence hypothesis states that SMs in ripe fruits deter seed predators but have little or no effect on seed dispersers. Indeed, studies have demonstrated that birds ...
متن کاملEndozoochorous seed dispersal of plant species in semi-steppe rangelands
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...

متن کاملانتقال بذر توسط علفخواران اهلی در اکوسیستم‌های مرتعی منطقه زاگرس مرکزی
To assess seed dispersal by domestic herbivores (sheep and goat) in Central Zagros region, 12 different rangeland sites, located 200 km west of Isfahan city, were studied. For each site, a pooled dung sample of 10 freshly pellet groups from domestic herbivores was collected in four different periods (mid June, July, August and September) during grazing season (in total, 48 pooled dung samples)....
متن کاملInterspecific variation in primary seed dispersal in a tropical forest
1. We investigated the relationships of seed size, dispersal mode and other species characteristics to interspecific variation in mean primary seed dispersal distances, mean annual seed production per unit basal area, and clumping of seed deposition among 41 tropical tree species on Barro Colorado Island, Panama. 2. A hierarchical Bayesian model incorporating interannual variation in seed produ...
