Plethodon; biomass production; carbon; energy flow; energy transfer; forest ecosystems; forests; highlands; invertebrates; nutrient content; nutrients; salamanders and newts; trophic relationships; Missouri; New Hampshire
Abstract:
... The transfer of energy and nutrients largely depends on the role of animals in the movement of biomass between trophic levels and ecosystems. Despite the historical recognition that amphibians could play an important role in the movement of biomass and nutrients, very few studies have provided reliable estimates of abundance and density of amphibians to reveal their true importance. Here, we provi ...

Abstract:
... Self-fertilization can facilitate the colonization of new habitats because it allows a single individual to found a population. Here we investigated the relationship between mating systems and colonization in hay-scented fern (Dennstaedtia punctilobula (Michx.) T.Moore). Throughout eastern North America, this species has been called a “native invasive” for its tendency to dominate forest understor ...

Abstract:
... Pitcairnia encholirioides L.B.Sm. is an endangered species endemic to the Brazilian Atlantic Forest. This species exhibits limited flowering, late seed germination, and preference for clonal growth. Because little is known about its life cycle and female gametophyte development, the ovule development, gynosporogenesis, and gynogametogenesis were analysed to advance knowledge of the species’ life c ...
