Welcome to The Natural History Museum repository
The Natural History Museum is an international leader in the study of the natural world. Our science describes the diversity of nature, promotes an understanding of its past, and supports the anticipation and management of the impact of human activity on the environment.
The Museum's repository provides free access to publications produced by more than 300 scientists working here. Researchers at the Museum study a diverse range of issues, including threats to Earth's biodiversity, the maintenance of delicate ecosystems, environmental pollution and disease. The accessible repository showcases this broad research output.
The repository was launched in 2016 with an initially modest number of journal publications in its database. It will expand significantly in the future through the addition of more journal articles, book chapters, blogs and multimedia items from Museum scientists

SEM-microphotogrammetry, a new take on an old method for generating high-resolution 3D models from SEM images(Wiley, 2017-03-22)The method we present here uses a scanning electron microscope programmed via macros to automatically capture dozens of images at suitable angles to generate accurate, detailed three‐dimensional (3D) surface models with micron‐scale resolution. We demonstrate that it is possible to use these Scanning Electron Microscope (SEM) images in conjunction with commercially available software originally developed for photogrammetry reconstructions from Digital Single Lens Reflex (DSLR) cameras and to reconstruct 3D models of the specimen. These 3D models can then be exported as polygon meshes and eventually 3D printed. This technique offers the potential to obtain data suitable to reconstruct very tiny features (e.g. diatoms, butterfly scales and mineral fabrics) at nanometre resolution. Ultimately, we foresee this as being a useful tool for better understanding spatial relationships at very high resolution. However, our motivation is also to use it to produce 3D models to be used in public outreach events and exhibitions, especially for the blind or partially sighted.
The use of anthropogenic marine debris as a nesting material by brown boobies (Sula leucogaster)(Elsevier, 2018-10-11)Marine debris is pervasive worldwide, and affects biota negatively. We compared the characteristics of debris incorporated within brown booby (Sula leucogaster) nests throughout their pantropical distribution by assessing the type, colour and mass of debris items within nests and in beach transects at 18 sites, to determine if nests are indicators of the amount of debris in local marine environments. Debris was present in 14.4% of nests surveyed, with the proportion of nests with debris varying among sites (range: 0–100%). There was minimal overlap between the type or colour of debris found in nests and on adjacent beaches at individual sites. This suggests that brown boobies do not select debris uniformly across their distribution. We propose that the nests of brown boobies can be used as a sentinel of marine debris pollution of their local environment.
