The dietary preferences of most rodents, especially in tropical countries, are poorly known. In the tropics, rodent diversity can be high and several species can coexist in the same habitats. In order to better document the dietary habits of Southeast Asian murid and diatomyid rodents, we examined microwear patterns in 21 species, with a particular focus on those living in karst habitats. Five variables of microwear scars (scratches and pits) were counted and measured on the dental facet of the first molar hypocone. We observed large variation and overlap in microwear patterns between and within genera, suggesting that feeding ecology is diverse (mostly generalist omnivorous species) within species and genus. For species living in agro-ecosystems, few differences were observed when we compared sympatric species within a genus, suggesting that niche partitioning is not achieved by feeding, neither in terms of diet composition nor in the way food is processed, or that food items are more homogeneous in terms of physical properties that affect microwear patterns. Differences between sympatric species were more pronounced in forest or karst contexts, suggesting that specialisation and niche differentiation have persisted in more preserved environments. Finally, differences were also observed in urban ecosystems suggesting that the communities of rodents evolved niche partitioning in these human-modified habitats. Our results also revealed differences in microwear patterns between karst and non-karst rodents, with all karst species showing a trend towards increasing numbers of small scratches and small pits. This suggested that the karst environment may influence the dietary habits of rodents, either in terms of the composition of the diet or by altering the general characteristics of the food.

Abstract The repeatable among-individual variation in behavior (animal personality) is considered to affect fitness. The variation in personality traits is shaped by complex evolutionary mechanisms involving energy allocation and resource acquisition. However, an association between personality and individual performance in energy gain in the natural environment still seems underexplored. The aim of our study was to test a hypothesis that consistent individual variation in behavior affects the energy acquisition of unpredictable food resources. We predicted that more explorative individuals would be finding ephemeral food resources with higher probability than those less explorative. The quasi-experiment with ‘random-walking-feeders’ was performed to assess the use of unpredictable food resources in the natural habitat occupied by free-ranging arboreal rodents — edible dormice Glis glis . A repeated open field test at laboratory conditions was conducted to assess whether male dormice show consistent among-individual variation in behavior. The open field test analysis indicated two main components of dormice behavior: exploration and boldness, from which only the first one was repeatable and thus considered as a component of animal personality. The probability of finding a feeder increased with exploration, independently of dormice age and body size. The results indicate that exploration can be considered an adaptive trait that improves energy acquisition. We suggest that the behavioral among-individual variation within populations persists due to the usage of distinct foraging strategies in the face of fluctuations in food resources availability.
