“…However, we cannot exclude the possibility that the "ghost" population might represent a native source population that has gone extinct at the time of our sampling. Including material from herbarium samples in future genetic studies would help to assess the likelihood of this being the case (Besnard et al., 2018). Another explanation for a "ghost" population could be that the unknown source represents an unsampled population from another non‐native range that was not included in this study (e.g.…”

“…In addition to heritable changes in the genetic code, modifications of DNA that do not involve changes in DNA sequence also contribute to organism responses to environmental change (Burggren, 2016;Lind & Spagopoulou, 2018). Epigenetic changes can influence gene expression that may be targeted by selection, and epigenetic changes can influence many aspects of evolution (Banta & Richards, 2018). Heritable transgenerational epigenetic changes may be particularly relevant in populations with low levels of genetic diversity where epigenetic change may preface genetic adaptations (Burggren, 2016).…”

“…In addition, NHCs harbour an immense diversity of organisms. For example, global herbaria (NHCs for plant and fungi) store ~350 M specimens (Besnard et al., 2018). This diversity makes a large range of species accessible to studies of systematics, phylogenetics, domestication and evolutionary biology; this is especially useful for hard to locate species in the wild (including extinct or endangered species).…”

A long‐standing question in biology is how organisms change through time and space in response to their environment. This knowledge is of particular relevance to predicting how organisms might respond to future environmental changes caused by human‐induced global change. Usually researchers make inferences about past events based on an understanding of current static genetic patterns, but these are limited in their capacity to inform on underlying past processes. Natural history collections (NHCs) represent a unique and critical source of information to provide temporally deep and spatially broad time‐series of samples. By using NHC samples, researchers can directly observe genetic changes over time and space and link those changes with specific ecological/evolutionary events. Until recently, such genetic studies were hindered by the intrinsic challenges of NHC samples (i.e. low yield of highly fragmented DNA). However, recent methodological and technological developments have revolutionized the possibilities in the novel field of NHC genomics. In this Special Feature, we compile a range of studies spanning from methodological aspects to particular case studies which demonstrate the enormous potential of NHC samples for accessing large genomic data sets from the past to advance our knowledge on how populations and species respond to global change at multiple spatial–temporal scales. We also highlight possible limitations, recommendations and a few opportunities for future researchers aiming to study NHC genomics.

“…Natural history collections represent a spatio-temporal window on life on earth, allowing us to study the evolution of biological diversity [1][2]. They are therefore not merely a collection of static objects, but offer a vast source of information on the origin and functioning of biodiversity and the mechanisms underlying evolutionary diversification awaiting scientific inquiry [3][4].…”

Museomics for reconstructing historical floristic exchanges: Divergence of stone oaks across Wallacea

Bagui monophyletic, raising the possibility of multiple independent dispersals along the outer edge of Wallacea. This suggests that dispersal of large seeded tree genera throughout Malesia and across Wallacea may have been less affected by large geographic distances and the presence of marine barriers than generally assumed. We demonstrate the utility of MIGseq in museomic studies using non-model taxa, presenting the first range-wide genomic assessment of Lithocarpus and tropical Fagaceae as a proof-of-concept. Our study shows the potential for developing innovative genomic approaches to improve the capture of novel evolutionary signals using valuable natural history collections of hyperdiverse taxa.
