Seed predation limits post-fire recruitment in the waratah (Telopea speciosissima)
The role of post-dispersal seed predation in limiting seedling establishment after fire in T. speciosissima, in southeastern Australia was assessed and microsites with high-density vegetation and litter cover were more likely to have seed survival or germination than micro Sites with low-density cover.
Seed fate of Marah macrocarpus (Cucurbitaceae) following fire: do seedlings recruit from rodent burrows?

Findings of this study suggest that ecologists may have underestimated the role of burrows as locations for recruitment of large-seeded species.
Are seed dispersal and predation in fire-sensitive Persoonia species (Proteacae) associated with rarity?
Seed dispersal and predation are key processes affecting the colonization and extinction of populations in fire-prone environments. If these processes influence distribution and abundance, rare
Fire Occurrence Mediates Small-Mammal Seed Removal of Native Tree Species in a Neotropical Savanna
Seed dispersal and predation are critical processes for plant recruitment which can be affected by fire events. We investigated community composition of small mammals in gallery forests with distinct
Seed Banks, Seed Germination, and Implications for Conservation of the Endangered, Fire-Dependent Shrub, Arctostaphylos morroensis
ABSTRACT Conservation of obligate-seeding shrubs from Mediterranean-climate regions is an international conservation priority. Morro manzanita (Arctostaphylos morroensis) is one such shrub whose
Predispersal seed predation in shrubs of Grevillea (Proteaceae) from south-eastern Australia
Level of predispersal seed predation varied across different sampling years and species occupying the same site, with greatest losses in the two largest-seeded species.
Contingent fire effects on granivore removal of exotic woody plant seeds in longleaf pine savannas
It is suggested that ecotone habitats in this system experience greater seed removal than upland habitats, particularly as time since fire increases, and differences are mainly due to the activity of vertebrate granivores.
Are Long Fire-free Periods Needed to Maintain the Endangered, Fire-recruiting Shrub Arctostaphylos morroensis(Ericaceae)?
It is concluded that A. morroensis may require considerably longer than 40 years to establish an adequate seed bank to compensate for mortality and prevent population decrease or local extinction.
Flowering, seed dispersal, seed predation and seedling recruitment in two pyrogenic flowering resprouters
Doryanthes excelsa and T. speciosissima are amongst the slowest woody resprouting species to recruit seedlings after fire in south-eastern Australia and lag years behind species with soil or canopy seed banks.
Fire and flood: Soil‐stored seed bank and germination ecology in the endangered Carrington Falls Grevillea (Grevillea rivularis, Proteaceae)
The aims of this study were to examine the density and vertical distribution of the soil-stored seed bank and to investigate the role of heat and scarification as cues for germination of fresh and soil-Stored seed.


Changes in predispersal seed predation levels after fire for two Australian legumes, Acacia elongata and Sphaerolobium vimineum
Predispersal seed predation was estimated before and for 2-3 yr after a single fire for two legume species. The relationship between this seed predation and the build-up of a buried seedbank for
Soil seed bank dynamics in the rare obligate seeding shrub, Grevillea barklyana (Proteaceae)
The size and dynamics of the soil seed bank was small and increased during the first 16 years after fire before declining in the 21- and 26-year-old populations, which may limit population numbers.
Post-dispersal seed predation in grassland: its magnitude and sources of variation.
Post-dispersal seed predation by rodents and invertebrates, was studied in two grassland sites in Berkshire, UK and found density-dependence varied with seed size, with predation of large seeds less influenced by a reduction in seed density.
Factors contributing to postfire seedling establishment in chaparral : direct and indirect effects of fire
Comparison of the results of this study to those from similar experiments in maritime chaparral suggest that inconsistencies between the responses of Chaparral communities to fire may be due primarily to differences in species composition.
Small mammal responses to pyric successional changes in eucalypt forest
A replacement sequence in time was observed for species reaching their maximum abundance and was interpreted as species occupying stages in the succession when their optimal habitat requirements were fulfilled, which has important implications for the design of management policies using fire or fire regimes as tools for habitat maintenance or alteration.
Human activity has resulted in high fire frequency in many moist tropical savannas. To simulate the effects of increased fire frequency on woody plants of the cerrado savannas of Brazil, I
Ability of Prairie Rodents to Find Seeds in Plant Litter
Differential abilities of white-footed mice, deer mice and fulvous harvest mice to find seeds covered by 0 and 75 g of litter were assessed and imply that differences in the ability of grassland rodents to collect seeds in plant litter may be partially responsible for species-specific patterns of microhabitat.
