Identification of 100 fundamental ecological questions

Fundamental ecological research is both intrinsically interesting and provides the basic knowledge required to answer applied questions of importance to the management of the natural world. The 100th anniversary of the British Ecological Society in 2013 is an opportune moment to reflect on the current status of ecology as a science and look forward to high-light priorities for future work. To do this, we identified 100 important questions of fundamental importance in pure ecology. We elicited questions from ecologists working across a wide range of systems and disciplines. The 754 questions submitted (listed in the online appendix) from 388 participants were narrowed down to the final 100 through a process of discussion, rewording and repeated rounds of voting. This was done during a two-day workshop and thereafter. The questions reflect many of the important current conceptual and technical pre-occupations of ecology. For example, many questions concerned the dynamics of environmental change and complex ecosystem interactions, as well as the interaction between ecology and evolution. The questions reveal a dynamic science with novel subfields emerging. For example, a group of questions was dedicated to disease and micro-organisms and another on human impacts and global change reflecting the emergence of new subdisciplines that would not have been foreseen a few decades ago. The list also contained a number of questions that have perplexed ecologists for decades and are still seen as crucial to answer, such as the link between population dynamics and life-history evolution. Synthesis. These 100 questions identified reflect the state of ecology today. Using them as an agenda for further research would lead to a substantial enhancement in understanding of the discipline, with practical relevance for the conservation of biodiversity and ecosystem function. © 2013 The Authors.

ECJ Fundamental Rights Jurisprudence between Member States' Prerogatives and Citizens' Autonomy

This chapter provides an analysis of the European Court of Justice's Fundamental Rights Jurisprudence, focused on the potential of Member States to maintain any positive regulatory role in supporting citizens' autonomy on the one hand, and on the impact of the Court's case law on citizens' opportunities to actually enjoy human rights within societies (substantive autonomy). It first sketches the notion of autonomy which is proposed as base of fundamental rights protection and promotion within a social reality characterized by not democratically legitimated dominance based on wealth and economic power. It proceeds to contextualize ECJ case law on fundamental rights. This section starts with a quantitative appetizer, which will formalize some assumptions and test them on a total of 150 cases before the European judiciary. The paper then offers a more conceptual recount around fundamental rights to equality and non-discrimination on the one hand and around fundamental rights of workers to actively shape employment and labor relations on the other hand. In conclusion some suggestions are made of how ECJ fundamental rights doctrine could develop more positively in order to moderate diverging interests of different parts of the citizenry in protecting fundamental rights.

The EU Charter of Fundamental Rights in the case law of the European Court of Human Rights

The European Court of Human Rights has begun to refer to the EU Charter of Fundamental Rights in order to support its reasoning for interpreting the European Convention on Human Rights in a particular way. But the EU Charter does not yet have any special status in that regard, being treated by the Court as on a par with numerous other documents of international law. The Court’s use of the Charter began in connection with arts 8 and 12 of the Convention (the right to a family life and the right to marry) but in subsequent years it has been extended to many other Articles of the Convention. It is in relation to art.6 (the right to a fair trial) that the Charter’s influence has been most noticeable so far, the Court having changed its position on two important aspects of Article 6 partly because of the wording of the EU Charter. But the influence on art.3 (in relation to the rights of asylum seekers), art.7 (in relation to retroactive penal laws), art.9 (in relation to the right to conscientious objection) and art.11 (in relation to rights of trades unions) has also been significant. The potential for the Charter to have greater influence on the Court’s jurisprudence in years to come remains considerable.

Gender Equality under the Charter of Fundamental Rights - a new lease for positive action?

This paper, which was published as a chapter of a Festskrift for Professor Ruth Nielsen, analyses Article 23 CFREU, the new provision on gender equality. It argues that Article 23 adds to the notion of gender equality in EU law, and not only allows, but also demands positive action measures if necessary to ensure equality between women and men. The provision also demands that positive action measures are suitable to achieve their aim. This implies that the EU legislator has to adapt positive action measure to the specific needs of the sector. The paper offers a critique of the proposal to introduce women quotas in board rooms, as proposed by the EU Commission in late 2012. It argues that the Commission unimaginatively copied rules developed for the German public service into a different sector, although these rules have not proven particularly efficient even in the public service. Consequently, a proposal that is demanding, but adapted to the sector should be developed.

Inbreeding uncovers fundamental differences in the genetic load affecting male and female fertility in a butterfly

Inbreeding depression is most pronounced for traits closely associated with fitness. The traditional explanation is that natural selection eliminates deleterious mutations with additive or dominant effects more effectively than recessive mutations, leading to directional dominance for traits subject to strong directional selection. Here we report the unexpected finding that, in the butterfly Bicyclus anynana, male sterility contributes disproportionately to inbreeding depression for fitness (complete sterility in about half the sons from brother-sister matings), while female fertility is insensitive to inbreeding. The contrast between the sexes for functionally equivalent traits is inconsistent with standard selection arguments, and suggests that trait-specific developmental properties and cryptic selection play crucial roles in shaping genetic architecture. There is evidence that spermatogenesis is less developmentally stable than oogenesis, though the unusually high male fertility load in B. anynana additionally suggests the operation of complex selection maintaining male sterility recessives. Analysis of the precise causes of inbreeding depression will be needed to generate a model that reliably explains variation in directional dominance and reconciles the gap between observed and expected genetic loads carried by populations. This challenging evolutionary puzzle should stimulate work on the occurrence and causes of sex differences in fertility load.
