“…In this sense, forensic entomology has much to benefit from the use of spatial statistics because many important questions, both at the fundamental and practical levels, require a spatial solution. As evidence of this, it is useful to note that other fields of forensics (e.g., [50][51][52]), the field of criminology (e.g., [53]), and other fields studying decomposition (e.g., [54][55][56]) have already adopted spatial methods.…”

Spatial and scale effects have barely been considered in forensic entomology, despite their pervasive influence on most of the parameters affecting the development of insect larval stages and the progression of insect succession on cadavers. Here, we used smoothing/interpolation techniques and semivariograms to document the spatial dynamics of sarcosaprophageous Calliphoridae, an important forensic taxon, in the Greater Moncton area in New Brunswick, Canada. Results indicated that the spatial dynamics of Calliphoridae differed between species, some species showing strong patterns of regional aggregation while others did not. Multivariate spatial correlations indicated that interspecific relationships in space varied widely, ranging from local and large-scale aggregation to spatial anticorrelation between species. Overall, this study suggested that even within a restricted timescale, the spatial dynamics of Calliphoridae can operate at many scales, manifest in different patterns, and be attributed to multiple different causes. We stress that forensic entomology has much to benefit from the use of spatial analysis because many important forensic questions, both at the fundamental and practical levels, require a spatial solution.

“…For a resource to be considered available, it must be present and accessible. Landscape connectivity, physical barriers, artificial lighting, noise, and predation risk may deter or prevent wildlife from accessing a resource (Holloway 2018, Grande et al 2020, Mourant et al 2021). Furthermore, the availability of a preferred resource can be temporal (Amorim et al 2018).…”

While the use of anthropogenic resources by wildlife in degraded habitats has been frequently documented, the use of such alternative resources in natural and semi‐natural habitats is not yet well understood. We explored the use of artificial water sources by bats in a semi‐natural habitat by conducting acoustic monitoring surveys at swimming pools on Amakhala Game Reserve in the Eastern Cape of South Africa from 2018 to 2020. We identified 7 of 23 local species in 24,909 recorded activities associated with resource use at the swimming pools, including 1,374 feeding buzzes and 9,286 drinking buzzes. This study confirmed that bats were using swimming pools in the game reserve as a foraging and drinking resource and indicates that such anthropogenic features could be of value to bats and potentially other wildlife in natural and semi‐natural habitats.

During the mid-Pliocene (Zanclean, ca. ∼ 3.9 Ma), parts of the Canadian High Arctic experienced mean annual temperatures that were 14–22°C warmer than today and supported diverse boreal-type forests. The landscapes of this vegetated polar region left behind a fragmented sedimentary record that crops out across several islands in the Canadian Arctic Archipelago as the Beaufort Formation and correlative strata. Paleoecological information from these strata provides a high-fidelity window onto Pliocene environments, and prominent fossil sites yield unparalleled insights into Cenozoic mammal evolution. Significantly, many of the strata reveal evidence for life-sediment interactions in a warm-climate Arctic, most notably in the form of extensive woody debris and phytoclast deposits. This paper presents original field data that refines the sedimentological context of plant debris accumulations from the anactualistic High Arctic forests, most notably at the ‘Fyles Leaf Beds' and ‘Beaver Pond' fossil-bearing sites in the ‘high terrace deposits' of central Ellesmere Island. The former is a remarkably well-preserved, leaf-rich deposit that is part of a complex of facies associations representing lacustrine, fluvio-deltaic and mire deposition above a paleotopographic unconformity. The latter yields tooth-marked woody debris within a peat layer that also contains a rich assemblage of vertebrate and plant fossils including abundant remains from the extinct beaver-group Dipoides. Here we present sedimentological data that provide circumstantial evidence that the woody debris deposit at Beaver Pond could record dam-building in the genus, by comparing the facies motif with new data from known Holocene beaver dam facies in England. Across the Pliocene of the High Arctic region, woody debris accumulations are shown to represent an array of biosedimentary deposits and landforms including mires, driftcretions, woody bedforms, and possible beaver dams, which help to contextualize mammal fossil sites, provide facies models for high-latitude forests, and reveal interactions between life and sedimentation in a vanished world that may be an analogue to that of the near-future.

Size matters: When resource accessibility by ecosystem engineering elicits wood‐boring beetle demographic responses

Abstract: Disturbances represent an important component of ecosystem dynamics (Bengtsson et al., 2003). Episodic natural disturbances, for instance, are known to play a key role at different scales of magnitude in ecosystem renewal (Holling, 1986), spatial heterogeneity
