SummaryTwo closely related long-lived rosette plants in the genusLobelia occur on alpine Mount Kenya.Lobelia telekii grows in drier sites and is semelparous (dies after first reproduction).Lobelia keniensis grows in wetter sites and is iteroparous (flowers repeatedly). I used long-term data to evaluate two related models of the evolution of semelparity (‘reproductive effort’ and ‘demographic’), and found evidence to support only one. Eight years of population data indicate that a simple… 
A demographic model explains life‐history variation in Arabis fecunda
TLDR
Life-history variation in the perennial herb Arabis fecunda (Brassicaceae), in which differences in the frequency of iteroparity and terminal flowering (facultative semelparity) are expressed among populations, is reported on.
Meristem allocation and life-history evolution in herbaceous plants
TLDR
This work used phylogenetically independent contrasts to compare reproductive and vegetative function in annual semelparous and perennial iteroparous species.
A unique life history among tetrapods: An annual chameleon living mostly as an egg
TLDR
The discovery of a remarkable annual tetrapod from the arid southwest of Madagascar: the chameleon Furcifer labordi, with a posthatching life span of just 4–5 months is reported, suggesting that the notorious rapid death of chameleons in captivity may, for some species, actually represent the natural adult life span.
Echium simplex, ein seltener Schopfrosettenbaum auf Teneriffa
TLDR
It is concluded that E. simplex despite its restricted occurrence in a small area is not endangered at the moment, but the plant deserves careful observation to allow immediate conservation measures in case of a decline in population size.
Secondary reproduction in the herbaceous monocarp Lobelia inflata: time-constrained primary reproduction does not result in increased deferral of reproductive effort
TLDR
The characteristics of secondary reproduction found in L. inflata are consistent with predictions of incomplete or transitional evolution to annual semelparity.
Towards a general perspective on life-history evolution and diversification in parasitoid wasps
TLDR
Four life-history correlates out of the 11 investigated are shown to account for the association between the two predictors: the relative level of resource investment per egg, pre-adult lifespan, female lifespan, and maximum egg load.
Demography of the giant monocarpic herb Rheum nobile in the Himalayas and the effect of disturbances by grazing.
TLDR
It is concluded that natural populations of this unique species are viable, but that conservation efforts should be taken to minimise disturbances by grazing and to protect this slow-growing flagship plant from the high Himalayas.
Maternal Care, Iteroparity and the Evolution of Social Behavior: A Critique of the Semelparity Hypothesis
TLDR
Iteroparity was common both among nesting species with non-overlapping broods and in species where a female produces broods of different aged offspring in the same nest (within-nest iteroparity).
Evolutionary demography of long‐lived monocarpic perennials: a time‐lagged integral projection model
TLDR
The extended IPM accurately described the demography of a long-lived monocarpic perennial using data collected over a relatively short period and could show that the evolution of flowering strategies in short- and long- lived monocarps seem to follow the same general rules but with a longevity-related emphasis on survival over fecundity.
Reproductive ecology of five sympatric Agave Littaea (Agavaceae) species in central Mexico.
TLDR
It is proposed that the presence of diurnal pollinators may increase the reproductive success of the plant when offering pollinator services additional to the coadapted pollinator, and evidence for character displacement in rosette sizes and separation of spatial and temporal resource use in pollinator composition among species is found.

The Comparative Demography of Semelparous Lobelia Telekii and Iteroparous Lobelia Keniensis on Mount Kenya
TLDR
The evolution of semelparity in Mount Kenya Lobelias may have been favoured by the demonstrated higher adult mortality and greater time between reproductive episodes shown by Lobelia keniensis plants in drier sites.
A General Model of Comparative Fecundity for Semelparous and Iteroparous Life Histories
  • T. Young
  • Environmental Science
    The American Naturalist
  • 1981
TLDR
A general model is produced which incorporates population growth rate, juvenile and adult survivorship, prereproductive development time (PDT), time between reproductive episodes (TBR), and senescence and the biological implications of this model are discussed.
The adaptive significance of variations in reproductive habit in the Agavaceae
TLDR
This chapter summarises evidence implicating pollinator foraging behaviour as the factor which has led to the evolution of “Big Bang” reproduction in yuccas and agaves and considers the effects of variation in plant reproductive expenditure on the pollinators.
LOBELIA TELEKII HERBIVORY, MORTALITY, AND SIZE AT REPRODUCTION: VARIATION WITH GROWTH RATE
TLDR
Several age x stage interactions in the demography of Lobelia telekii, a long-lived semelparous rosette plant on Mount Kenya are demonstrated and it is suggested that slow-growing plants occupied less favorable microsites than fast- growing plants.
COMPARATIVE REPRODUCTIVE BIOLOGY OF ALPINE BIENNIAL AND PERENNIAL GENTIANS (GENTIANA: GENTIANACEAE) IN CALIFORNIA.
TLDR
Seed production in the perennial species was limited by high rates of flower predation, insufficient amounts of pollen reaching stigmas, an unusually late flowering period, and by the relatively small proportion of biomass allocated to reproduction.
A comparative demographic study of annual and perennial Hypochoeris (Asteraceae)
TLDR
A population model was used to compare effects of variation in seed mortality and dormancy on annual and perennial population growth rates in annuals and perennials.
The Adaptive Significance of Variations in Reproductive Habit in the Agavaceae II: Pollinator Foraging Behavior and Selection for Increased Reproductive Expenditure
TLDR
A coevolutionary hypothesis accounting for the evolution of Big Bang reproduction in yuccas and agaves is proposed, and evidence incidentally supports the notion that insect pollinators visit flowers in qualitative accord with the dictates of optimal diet theory.
Intermediate perennial-annual populations ofOryza perennis found in Thailand and their evolutionary significance
TLDR
It is suggested that the intermediate perennial-annual type is probably the wild progenitor ofO.
Energy Allocations in Annual and Perennial Lupines (lupinus: Leguminosae)
The energy allocation patterns of 3 species of lupine, an annual, a perennial herb, and a shrub were investigated and related to life cycle differences as well as ecological differences among the
Reproductive strategies and growth patterns in four legumes
TLDR
The stolons of T. repens can behave as an r strategist in an environment imposing density-dependent regulation (a ‘K' type environment) and thus permit this species to reproduce sooner than Medicago lupulina can reproduce by seed.
