Energetics and Water Flux in the Subterranean Rodent Family Bathyergidae

Frontiers in Ecology and Evolution, 2022
The doubly labeled water (DLW) technique and indirect calorimetry enable measurement of an animal’s daily energy expenditure (DEE, kJ/day), resting metabolic rate (RMR, kJ/d), sustained metabolic scope (SusMS), body fat content (BF, %) as well as water turnover (WTO, ml/day), and water economy index (ml/kJ). Small mammals have been the primary focus of

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

Journal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Detection of human-induced environmental disturbances in a show cave [PDF]

, 2011
Purpose: We investigated the effects of human-induced disruption in a subterranean stable environment containing valuable Palaeolithic paintings and engravings (Ardales Cave, Southern Spain) using a double analytical approach.

The mTORC1/eIF4E/HIF-1α Pathway Mediates Glycolysis to Support Brain Hypoxia Resistance in the Gansu Zokor, Eospalax cansus

Frontiers in Physiology, 2021
The Gansu zokor (Eospalax cansus) is a subterranean rodent species that is unique to China. These creatures inhabit underground burrows with a hypoxia environment.

Chinese Pangolin Changes Local Vertebrate Assemblages and Contributes to Their Interspecific Interactions by Burrowing and Revisitation

Integrative Zoology, EarlyView.
In this study, we systematically analyzed the utilization patterns of Chinese pangolin burrows by sympatric species in Guangdong Province, China, including differences in species composition using burrow mounds and burrow tunnels. We found that repeated visits to burrows by Chinese pangolin promoted the use of burrows by sympatric species, suggesting ...

Transcriptome analysis of the response provided by Lasiopodomys mandarinus to severe hypoxia includes enhancing DNA repair and damage prevention

Frontiers in Zoology, 2020
Background Severe hypoxia induces a series of stress responses in mammals; however, subterranean rodents have evolved several adaptation mechanisms of energy metabolisms and O2 utilization for hypoxia.

Masticatory musculature of the African mole-rats (Rodentia: Bathyergidae) [PDF]

PeerJ, 2020
The Bathyergidae, commonly known as blesmols or African mole-rats, is a family of rodents well-known for their subterranean lifestyle and tunnelling behaviour. Four of the five extant bathyergid genera (Cryptomys, Fukomys, Georychus and Heliophobius) are

Prenatal Environmental Hypoxia Enhances Adult Hypoxia Tolerance in Brandt's Voles (Lasiopodomys brandtii): Behavioral and Transcriptomic Insights

Integrative Zoology, EarlyView.
Prenatal hypoxia enhances adult hypoxia tolerance in Brandt's voles, preserving cognitive and memory functions. Transcriptomic analysis reveals adaptive changes in energy metabolism, oxygen transport, and neuroprotective mechanisms, highlighting developmental plasticity.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...
