Boom and bust: a review of the physiology of the marsupial genus Antechinus
TLDR
The high degree of life history synchrony and the cascade of endocrine-driven physiological events that result in male death are unusual physiological characteristics for mammals.
Eimeria taggarti N. Sp., a Novel Coccidian (Apicomplexa: Eimeriorina) in the Prostate of an Antechinus flavipes
TLDR
Bayesian phylogenetic analysis based on 18S rDNA gene sequences revealed that the novel coccidian clusters with reptile-host coccidians, forming an ancestral basal lineage of the eimeriid clade.
Breeding biology and growth in a new, threatened carnivorous marsupial
TLDR
There was a marked difference in A. argentus numbers between years and sites, and it is hypothesised that the disparate capture rates between sites may be at least in part linked to the effects of fire on vegetation.
Sperm competition drives the evolution of suicidal reproduction in mammals
TLDR
It is shown that as marsupial predators in Australia, South America, and Papua New Guinea diversified into higher latitudes, seasonal predictability in abundance of their arthropod prey increased in multiple habitats, and precopulatory sexual selection by females favored the evolution of suicidal reproduction in mammals.
Semelparity and Factors Affecting the Reproductive Activity of the Brazilian Slender Opossum (Marmosops paulensis) in Southeastern Brazil
TLDR
It is suggested that fruit availability controlled the length of breeding activity in M. paulensis, and it could play a role in the occurrence of semelparity in this species, however, semelParity may occur only due to phylogenetic constraints, whereas food supply works as a selective force maintaining this trait.
Size breeds success: multiple paternity, multivariate selection and male semelparity in a small marsupial, Antechinus stuartii
TLDR
Investigation of selection in male brown antechinus, Antechinus stuartii, and paternity success in 119 males is found to be related most strongly to body mass and scrotal size, thus providing support for both hypotheses for the evolution of semelparity.
A chromosome‐level genome of Antechinus flavipes provides a reference for an Australian marsupial genus with male death after mating
TLDR
The chromosome‐level A. flavipes genome provides a steppingstone to understanding an enigmatic life‐history strategy and a resource to assist the conservation of antechinuses.
Reproductive Suicide: Similar Mechanisms of Aging in C. elegans and Pacific Salmon
TLDR
It is argued that mechanisms of senescence operative in reproductive death exist in a less catastrophic form in iteroparous organisms, particularly those that involve costly resource reallocation, and exhibit endocrine-regulated plasticity.

Corticosteroid levels and male mortality in Antechinus stuartii
TLDR
Examining populations with simple, easily determined age structure, which also show abrupt changes in numbers, is begun.

TLDR
Mortality had a greater influence on population size than reproduction, and late sexual maturity and stereotyped reproductive pattern seem to preclude cyclical changes in population density.
Environmental Certainty, Trophic Level, and Resource Availability in Life History Evolution
TLDR
This work uses well-studied examples from the literature to identify causal mechanisms in the evolution of many well-known organisms and suggests the density of the population in relation to resources, the trophic and successional position of the Population, and predictability of mortality patterns all appear to be important determinants of adaptive strategies.
Optimal Reproductive Effort in Fluctuating Environments

TLDR
The possibility that iteroparity may be an evolutionary response to uncertain survival from zygote to first maturity is examined in a competition model and a genetic model and suggests the approach may contribute to understanding the dynamics of evolution.

Selection for Optimal Life Histories: The Effects of Age Structure
TLDR
It is shown that an optimal life history maximizes for each age class the expected fecundity at that age plus the sum of all future expected parameters, which suggests that related species, with similar ecologies, may have very different life histories, the differences resulting from historical accidents that have trapped each on a different adaptive peak.
