On the correlation between heterozygosity and fitness in natural populations
TLDR
An account of the recent progress on the subject of heterozygosity at polymorphic DNA markers is provided, and suggestions on how to distinguish between the three hypotheses in future studies are given.

Performance of Marker-Based Relatedness Estimators in Natural Populations of Outbred Vertebrates
TLDR
The five examples of vertebrate breeding systems suggest that due to the remarkably low variance in relatedness across the population, marker-based estimates may often have low power to address research questions of interest.

Temporal dynamics and diversity of avian malaria parasites in a single host species.
TLDR
A remarkable diversity of parasite lineages are unraveled in a long-term population study of great reed warblers Acrocephalus arundinaceus that was not foreseen from traditional microscopic examination of blood smears, suggesting that knowledge of extrinsic parameters such as vector distribution and alternative hosts are required to understand these patterns.

Selection for Heterozygosity Gives Hope to a Wild Population of Inbred Wolves
TLDR
The data show that for each level of f, it was the most heterozygous wolves that established themselves as breeders, a selection process that seems to have decelerated the loss of heterozygosity in the population despite a steady increase of f.

Hidden costs of infection: Chronic malaria accelerates telomere degradation and senescence in wild birds
TLDR
In a wild population of great reed warblers, it was found that low-level chronic malaria infection reduced life span as well as the lifetime number and quality of offspring.

New methods to identify conserved microsatellite loci and develop primer sets of high cross‐species utility – as demonstrated for birds
TLDR
A new approach to create microsatellite primer sets that have high utility across a wide range of species was developed using birds and the success was demonstrated using birds.

DOES LINKAGE DISEQUILIBRIUM GENERATE HETEROZYGOSITY‐FITNESS CORRELATIONS IN GREAT REED WARBLERS?
TLDR
The present finding of a significant within‐family multilocus heterozygosity‐survival association in a nonequilibrium population supports the view that LD generates HFCs in natural populations.

Microsatellite diversity predicts recruitment of sibling great reed warblers
TLDR
Evidence from wild birds is presented that genetic variation at five microsatellite loci predicts the recruitment success of siblings in great reed warblers, suggesting that the micros Satellite markers, which are generally assumed to be neutral, cosegregated with genes exhibiting genetic variation for fitness.

Maternal and genetic factors determine early life telomere length
TLDR
This study analysed telomere length measured early in life in both parents and offspring and applied statistical models (so-called ‘animal models') that are based on long-term pedigree data, which revealed a significant heritability and an equally large maternal effect.
