Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Effects of Hibernation on Colonic Epithelial Tissue and Gut Microbiota in Wild Chipmunks (Tamias sibiricus)

open access: yesAnimals
The gut microbiota plays a crucial role in the host’s metabolic processes. Many studies have shown significant changes in the gut microbiota of mammals during hibernation to adapt to the changes in the external environment, but there is limited research ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

open access: yesInsect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Liver transcriptome analysis reveals the molecular response to hibernation challenge in the Chinese soft-shelled turtle (Pelodiscus sinensis)

open access: yesFrontiers in Marine Science
Hibernation is a physiological strategy animals use to survive in hostile environments with extreme temperature challenges and food scarcity. During this state, significant changes occur in metabolism and cellular function, with numerous stress response ...

Immunoreactivities of PPARγ2, leptin and leptin receptor in oviduct of Chinese brown frog during breeding period and pre-hibernation

open access: yesEuropean Journal of Histochemistry, 2014
The Chinese brown frog (Rana dybowskii) is a special amphibian with one unique physiological phenomenon, which is that its oviduct expands prior to hibernation, instead of during the breeding period.

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

open access: yesIntegrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

The effect of hibernation on the morphological structure and expression of creatine kinase in the intestine of Pelodiscus sinensis

open access: yesAquaculture Reports
The intestinal function of hibernating animals undergoes seasonal changes, during which they are in a fasting state, which also affects the morphology, structure, and function of intestine.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians

open access: yesIntegrative Zoology, EarlyView.
We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.
