What the literature leaves open
The study addresses the lack of understanding of species range expansions to lower latitudes. The research fills a gap in the knowledge of the Italian parti-coloured bat's genetic and ecological uniqueness.
The Arctic ground squirrel (AGS, Urocitellus parryii) is a valuable model for studying extreme physiology, including metabolic suppression during hibernation and resistance to cerebral ischemia/reperfusion, yet no studies have evaluated AAV performance in the AGS brain.
Serotype-dependent differences in AAV cellular transduction rates in the hypothalamus of Arctic ground squirrels · 2026 · DOIThere is limited data on nucleus-specific regulatory mechanisms underlying torpor control in Djungarian hamsters. The specific mechanisms by which the hypothalamus coordinates torpor are not well understood.
Daily torpor in the Djungarian hamster (Phodopus sungorus) is orchestrated by the suprachiasmatic nucleus: evidence from immediate early gene mapping and nucleus-specific sequencing · 2026 · DOIThe Mexican Ground Squirrel was excluded from analysis due to an extremely small sample size (n = 1). The limited sample size in the daily heterotherm group (n = 13) may not infer a relationship.
The applicability of Bergmann's rule is highly debated due to the definition itself. There is a lack of studies examining the adherence to Bergmann's rule in heterothermic species.
Future studies may investigate the metabolic adaptation of other species or tissues to extreme energetic demands. The development of novel therapeutic strategies for cardiovascular disease may be informed by the study's findings. Further research may apply the study's approach to other species or tissues.
Metabolomics-constrained modelling reveals dominant oxidative metabolism in the Egyptian fruit bat myocardium · 2026 · DOIThe research highlights the need for further study of the impacts of urbanisation and climate change on urban biodiversity.
Native and immigrant bat niches in a city agglomeration: implication for urban landscape planning · 2026 · DOIFuture research should examine whether operational-state-dependent avoidance occurs in other regions and seasons. This study was conducted at two turbines at a single wind facility during fall migration, and the generalizability of these patterns across seasons, regions, and turbine configurations remains unknown.
Integrating 3-D thermal videography, ultrasonic acoustics, and weather radar to characterize bird and bat activity at wind turbines · 2026 · DOIBats can spread an array of infections caused by bacteria, viruses, fungi, and protozoa, although it is not fully understood the extent to which bats participate in zoonotic spillover.
Neotropical bats as sentinels for emerging zoonoses in Central America: A case study identifying Trypanosoma cruzi in bats from Belize using metagenomic next-generation sequencing · 2026 · DOIThe natural drivers shaping community variation at different spatial scales are largely unknown. The responses of particular biotic communities of savanna to extrinsic drivers promoting the habitat mosaic differ. There is a need to understand the bat communities in the savanna biome of Kruger National Park, South Africa.
The study faced challenges due to the remote location of the island and the limited availability of recording devices. The study faced challenges due to the cryptic nature of bat species and the difficulty of detecting them. The study faced challenges due to the limited number of sampling sites and the malfunction of recording devices at some sites.
Bats of a remote island: integrated genetic and bioacoustics monitoring confirms species occurrence in Flores (Azores, Portugal) · 2026 · DOIThere is a lack of understanding of viral dynamics in synanthropic molossid bats. The study aims to address this gap by assessing viral dynamics in two populations of Mops spp.
Longitudinal surveillance of synanthropic molossid bats reveals viral diversity and temporal patterns at the human–bat interface · 2026 · DOIDeveloping a methodology that can be applied to different bat species. Validating the methodology using a limited sample size. Investigating the application of the methodology to conservation efforts and disease monitoring in bat populations.
The number of species that have been reported for Algeria has essentially not changed since Kowalski and Rzebik-Kowalska (1991). There is still a lot of work to be done regarding a detailed knowledge of the distribution of bat species throughout Algeria. Many areas of Algeria lack surveys due to the country's large size and remote areas.
Future studies could investigate the role of kinship in co-swarming behavior, and explore the potential for reciprocal behaviors such as sharing and allogrooming. Further research could also examine the social importance of dawn swarming in roost selection within this species' fission-fusion dynamics.
Limited visibility of ground squirrels during certain times of the day. Challenges in identifying individual squirrels and recording their behavior.
Columbian ground squirrels cope with high thermal variability of montane habitats through behavioral thermoregulation · 2026 · DOIBecause high Cu-exposure causes alterations in select DNA-associated proteins and basic carbon-, nitrogen- and sulfur-metabolic proteins, further investigation into these pathways is warranted.
The performance of AAV vectors can vary across species and brain regions.
Serotype-dependent differences in AAV cellular transduction rates in the hypothalamus of Arctic ground squirrels · 2026 · DOIThe study was limited to a small number of sampling sites. The recording devices malfunctioned at two sites, reducing the number of available data points. The study relied on a single collected specimen for genetic analysis.
Bats of a remote island: integrated genetic and bioacoustics monitoring confirms species occurrence in Flores (Azores, Portugal) · 2026 · DOIThe study only focused on two populations of Mops spp. in northeastern Eswatini. The sample size was limited to 692 bats. No filovirus RNA was detected among the 772 samples tested.
Longitudinal surveillance of synanthropic molossid bats reveals viral diversity and temporal patterns at the human–bat interface · 2026 · DOIThe sample size was limited. The study did not investigate the application of the methodology to other bat species.
The study was limited by the COVID-19 restrictions, which affected the data collection. The dataset was reduced by 13% due to the age category change of some individuals. The study only analyzed the subset of data from midnight onwards.
Future research should address key gaps such as temporal replication across several winters to evaluate seasonal and yearly cave use and assemblage stability; expanding elevational sampling beyond 1334 m to find high-elevation specialists and upper thermal limits; combining cave morphology, depth, and microclimate to improve thermal buffering predictions under warming; and genetic analyses to examine population…
Thermal Niche Differentiation Shapes the Hibernating Bat Assemblages in Bulgarian Caves Across an Elevational Gradient · 2026 · DOIConducting bat inventories across Algeria, - Fine mapping of habitat preferences, - Establishment of conservation targets, - Investigating the bat species present at specific…
Compared with recent range maps, inferred distributions differ for Glossophaga commissarisi Gardner, 1962 and Glossophaga leachii (Gray, 1844), and reveal geographically isolated populations occupying distinct habitat types and biogeographic provinces, warranting further examination.
