The growth and spawning of Lacuna pallidula and L. vincta were measured in the laboratory over 7 months. In both cases, there were significant differences between the mean number of eggs per batch or weight of egg batches from females of the same species and also between rates of spawning by females of the same species. The reproductive effort of L. vincta, estimated by the ratio total spawn weight: body weight and by the time taken to exceed body weight in cumulative spawn, is approximately… Expand
Reproductive energetics of two species of dorid nudibranchs with planktotrophic and lecithotrophic larval strategies
TLDR
It appears that there is a threshold of absolute energy required to support the lecithotrophic larval strategy in nudibranchs, and that this is not attained by the smaller species, A. muricata, but by the larger species, O. proxima, which appears to have both reproductive strategies open to it.

Inter- and intraspecific patterns of reproductive effort in four species of cone shells (Conus spp.)
TLDR
Data on the 4 species of Conus examined support the hypothesis that reproductive effort should be positively correlated with extrinsic adult mortality and negatively correlated with the variability of juvenile survivorship and suggest a possible relationship between reproductive effort and the cost of parental care.

Reproductive effort of winkles (Littorina spp.) with contrasted methods of reproduction
TLDR
No general relationship was found between the magnitude of reproductive effort and either reproductive type or population ecology among the Littorina spp. Expand
On the biology of the prosobranch Lacuna Parva in the Øresund
TLDR
The habitats of 2 sparse populations of Lacuna parva in the northern Oresund are described and the species has an annual life cycle with copulation prior to the production of spawn in March, death of adults in May–June and main hatching of young in June–July. Expand
Reproductive strategies in contrasting populations of the coastal gastropod Hydrobia ulvae. II. Longevity and life-time egg production
TLDR
It is argued that H. ulvae may biologically be an iteroparous species that is normally rendered functionally semelParous by high rates of mortality, and that considerable evolution towards a true semelparous reproductive strategy has occurred. Expand
Reproductive effort in four species of intertidal limpets
TLDR
Reproductive effort was measured in 4 species of intertidal limpets from south-eastern Australia, and these 4 species are ranked in different orders with respect to “reproductive effort”, depending upon which index is used. Expand
Patterns of reproduction in different populations of five species of the amphipod genus Gammarus
TLDR
Different features of reproduction were studied in five species of Gammarus in the Baltic Sea and in the Limfiord, Denmark and in two species at localities along the west coast of the European continent. Expand
On living in cold water: K-strategies in antarctic benthos
TLDR
It is concluded that many features of the polar benthos are explicable in terms of a general evolution of typical K-strategies and the role of low temperature in the widespread evolution of K-Strategies may be crucial. Expand
Reproductive Strategies of Marine Benthic Invertebrates: A Settlement-Timing Hypothesis
TLDR
It is proposed that for a given species there is an optlmal time to spawn and an optimal time for the larva to settle and that a species in which two or more alternative strategies appear supportable may select that strategy which appropriately 'bridges' the period between the optimal time tospawn and to settle.

Fecundity and energy partitioning in Capitella capitata type I (Annelida: Polychaeta)
TLDR
Assessment of reproductive energetics in a laboratory population of the capitellid polychaete Capitella capitata type I found that reproductive output varies more widely and is greater than in other iteroparous polychaetes. Expand

EFFECT OF WAVE ACTION AND COMPETITION ON BROODING AND REPRODUCTIVE EFFORT IN THE SEASTAR, LEPTASTERIAS HEXACTIS'
TLDR
Comparisons of life history characteristics of two competing starfish suggest the generality of r- and K-selection theory should be determined before theoretical elabora- tion of this theory is safe. Expand

Lizard reproductive effort: caloric estimates and comments on its evolution
TLDR
The energy content of eggs of 10 lizard species was determined and used as a measure of reproductive effort, suggesting that the demographic environment may not be the primary selec- tive pressure determining reproductive efforts, and that reproductive effort mayNot be posi- tively correlated with age in all species.

The Concept of r- and K-Selection: Evidence from Wild Flowers and Some Theoretical Considerations
TLDR
The crucial evidence needed for r- and K-selection is whether an organism is allocating a greater proportion of its resources to reproductive activities than another related one (K-strategist) under any and all D.I. mortality conditions. Expand

TLDR
It is evident that the effects of these rhythms upon the population dynamics of pelagic invertebrate larvae, as demonstrated by the present data on the Velikaya Salma Sound, must also follow world-wide regularities. Expand
