The “Evolutionarily Significant Unit” concept and its applicability in biological conservation

LP Casacci, F Barbero, E Balletto - Italian Journal of Zoology, 2014 - Taylor & Francis
Although most conservationists claim to protect “species”, the conservation unit actually and
practically managed is the individual population. As resources are not unlimited, we need to …

Evidence based conservation of butterflies

JA Thomas, DJ Simcox, T Hovestadt - Journal of Insect Conservation, 2011 - Springer

Limited evidence for the demographic Allee effect from numerous species across taxa

SD Gregory, CJA Bradshaw, BW Brook… - Ecology, 2010 - Wiley Online Library
Extensive theoretical work on demographic Allee effects has led to the latent assumption
that they are ubiquitous in natural populations, yet current empirical support for this …

Lessons from insect conservation in Russia

SM Govorushko, P Nowicki - Journal of Insect Conservation, 2019 - Springer
Insect conservation in Russia has a long history, but it has been developing partly
independently from the conservation tradition of the Western world, and consequently it is …

Evidence for positive density-dependent emigration in butterfly metapopulations

P Nowicki, V Vrabec - Oecologia, 2011 - Springer
A positive effect of (meta) population density on emigration has been predicted by many
theoretical models and confirmed empirically in various organisms. However, in butterflies …
