Tropical rodents change rapidly germinating seeds into long-term food supplies

Article Abstract:

A series of experiments was carried out to understand why red acouchies (Myoprocta exilis) scatter hoard Carapa procera seeds, which lack dormancy and germinate rapidly. It was found that acouchies intervened in germination by removing the protruding radicle and epicotyl after which they re-cached seeds suggesting that the trees use the rodents to achieve seed dispersal and gain from imperfect intervention in germination by the rodents.

Degree distribution in plant-animal mutualistic networks: Forbidden links or random interactions?

Article Abstract:

The study shows that ecological interaction networks depart from the 'scale-free' topologies observed in many other real world networks. The topology of 17 plant-animal mutualistic networks predicted by a simple null model that assumes that a species degree is a function of its frequency of interaction is compared.

Importance of Silene latifolia ssp. alba and S. dioica (Caryophyllaceae) as host plants of the parasitic pollinator Hadena bicruris (Lepidoptera, Noctuidae)

Article Abstract:

The mutualistic relationships between Hadena-species and Caryophyllaceae are studied. The pupal weight of animals reared on the seeds of S. latifolia ssp. alba was found to exceed that of animals reared on the seeds of S. dioica.

Study and teaching, Caryophyllaceae
