Article Reference Fitness-heterozygosity associations differ between male and female winter moths Operophtera brumata L.
The association between heterozygosity and fitness is positive but weak on average and varies between studies. inbreeding has been invoked as the driving force between the positive heterozygosity-fitness associations, yet in spatio-temporally stable environments a negative correlation is expected. Furthermore, different patterns can arise because of the effects of natural selection on different loci and variation can be expected among groups of individuals that experience different levels of stress. In this paper we report on fitness-heterozygosity associations in the winter moth for six allozyme loci. The relationship is estimated for males and females separately, in four areas differing in their degree of fragmentation, and variation among loci is modelled. We introduce a linear mixed model framework to achieve this analysis. This approach differs from more traditional (multiple) regression analyses and allows testing specific interactions. We show that fitness, as estimated by body size, is negatively correlated with heterozygosity, but only so in females. This association does not vary significantly among loci and the four areas. We speculate that a trade-off between fitness-consequences of inbreeding and outbreeding at different stages of the winter moth life cycle could explain the observed patterns.

Article Reference A comparison of gene flow estimates based on private allele frequencies.
The frequency of private alleles is often used to assess the amount of gene flow (Nm) between populations, with the equations proposed by SLATKIN (1985b) and by SLATKIN and BARTON (1989). Although these equations express the same relationship, they may yield different estimates of gene flow for the same data. These differences increase with decreasing frequencies of private alleles. Comparisons of Nm estimates, based on different equations can therefore be misleading. It is advisable to use these equations method only to distinguish between Nm > 1 and Nm < 1.

Article Reference The EU Biodiversity Strategy for 2030: Opportunities and challenges on the path towards biodiversity recovery
The European Union (EU) has committed to an ambitious biodiversity recovery plan in its Biodiversity Strategy for 2030 and the Green Deal. These policies aim to halt biodiversity loss and move towards sustainable development, focusing on restoring degraded habitats, extending the network of protected areas (PAs), and improving the effectiveness of management, governance, and funding. The achievement of conservation goals must be founded on understanding past successes and failures. Here, we summarise the strengths and weaknesses of past EU biodiversity conservation policies and practices and explore future opportunities and challenges. We focus on four main aspects: i) coordination among and within the EU Member States, ii) integration of biodiversity conservation into socio-economic sectors, iii) adequacy and sufficiency of funds, and iv) governance and stakeholder participation.Whilst past conservation efforts have benefitted from common rules across the EU and funding mechanisms, they have failed at operationalizing coordination within and across the Member States, integrating biodiversity conservation into other sectoral policies, adequately funding and effectively enforcing management, and facilitating stakeholder participation in decision-making. Future biodiversity conservation would benefit from an extended and better-managed network of PAs, additional novel funding opportunities, including the private sector, and enhanced co-governance. However, it will be critical to find sustainable solutions to potential conflicts between conservation goals and other socio-economic objectives and to resolve inconsistencies across sectoral policies.
