ACTA OECOLOGICA-INTERNATIONAL JOURNAL OF ECOLOGY
ELSEVIER
Forests exhibit complex three-dimensional structures, wherein abiotic factors vary both vertically and horizontally. The interaction between organisms and these factors drives the remarkable biodiversity within forests. Tree trunks serve as vital conduits for organisms moving vertically within the forest, facilitating biodiversity maintenance. Organisms moving vertically through tree trunks in forests face varying abiotic conditions, which may enhance their resilience to long-term environmental changes. Despite numerous studies comparing canopy and ground communities, the distribution of organisms across multiple strata remains poorly understood. Here, we explore the correlation between the horizontal distribution of ants in a forest and environmental factors (topography, tree size, tree species), with a specific focus on their presence on tree trunks. Visual observations were conducted to document ant species richness on tree trunks, supplemented by pitfall traps to quantify soil arthropod biomass, serving as an indicator of protein availability. The results revealed that ant species richness on tree trunks varied based on topography and tree species, showing a positive correlation with tree size. However, no significant relationship emerged between soil arthropod biomass and ant richness on tree trunks. Furthermore, no discernible trend suggesting that certain species were less likely to co-occur was observed; instead, a tendency for some species to co-occur was found. These findings highlight the horizontal heterogeneity in the distribution of ants with respect to topography, tree species, and tree size within the forest.

Ants are known to show diverse mating behaviors across different species, but detailed reports on such behaviors are limited to only 0.7% of ant species. Therefore, we report on the mating behavior of the alate females and males in the small carpenter ant, Camponotus yamaokai. . Its process was classified into two phases: mating attempt and copulation. Out of the 53 pairs we observed, 23 pairs engaged in a total of 36 mating attempts. The mating attempt durations in cases where copulation failed were significantly longer than those leading to copulation. Among these attempts, copulation was observed ten times in 9 pairs, including multiple mating in one pair. The copulation lasted for 24.0 +/- 5.1 seconds (mean +/- SD). At the end of copulation, males pulled out their genitalia quickly to avoid potential attacks from the females. This behavior might be a strategy of males to minimize the risk of mortality during a single mating and support them in engaging in multiple matings.

Fear of thunder in dogs is notably prevalent worldwide. When the symptoms are severe, it becomes a notable stressor for dogs, not only shortening the dog's lifespan but also becoming a significant burden for the owner. Therefore, identifying the risk factors is crucial. Through previous research, some factors influencing the fear of thunder are known, but the impact of living environments and pet owners remains poorly understood. In this study, an online questionnaire was conducted to explore the risk factors for fear of thunder. The questionnaire included questions about fear of thunder, demographic features of dogs, and information regarding living environments, as well as the symptoms of fear of thunder, owner reactions, the age of onset or remission of symptoms, and the triggers associated with the onset or remission. A total of 1326 valid responses were obtained. According to the owners' reports, 43.6% of dogs exhibit fear of thunder. The symptoms obtained from the questionnaire indicated typical fear-related behaviors in dogs. Vocalization was independent of other symptoms. Those who have never been fearful of thunder were younger compared to those who have experienced fear of thunder. The results revealed that the prevalence rate increased with age but decreased in the elderly. Miniature Dachshunds and Toy Poodles were less fearful compared to other breeds. Dogs living in houses exhibited higher fear of thunder compared to dogs living in apartments. We also showed that dogs were significantly more fearful of thunder when their owners were afraid of it. The probability of fear of thunder increased when risk factors were stacked. The frequency of thunder in the region and the frequency of thunder during the dog's socialization period were not found to be significantly associated with fear of thunder. These findings suggest that a dog's fear of thunder is influenced not only by previously reported factors but also by the owner and living environment. We expect that this study contributes to the prevention, treatment, and management of the fear of thunder ultimately leading to the improvement of the well-being of dogs and their owners.

Ergatandromorphs are examples of genetic chimeras found in ants, in which they exhibit features of both minor workers and males. In this study, we report a lateral ergatandromorph of Camponotus yamaokai Terayama & Satoh, 1990. The right side of this specimen was characterized as a male and the left side as a minor worker, although some body parts did not show a clear division. The specimen had partially atrophied genitalia on the right side of the metasoma while the genital structures on the left side were absent. The individual engaged in frequent self-grooming and received trophallaxis and allogrooming from the nestmates. This is the first report of the lateral ergatandromorph in the genus Camponotus, which has few documented cases of gynandromorphism.

Fibrinogen A alpha-chain amyloidosis is a hereditary systemic amyloidosis characterized by glomerular amyloid depositions, which are derived from the fibrinogen A alpha-chain variant in humans. Despite its unique pathology, the pathogenic mechanisms of this disease are only partially understood. This is in part because comparative pathological studies on fibrinogen A alpha-chain amyloidosis are currently unavailable as there is a lack of reported cases in animals other than humans. In this study, mass spectrometry-based proteomic analyses of Japanese squirrels (Sciurus lis) that died in five Japanese zoos showed that they developed glomerular-associated fibrinogen A alpha-chain amyloidosis with an extremely high incidence rate (29/38 cases, 76.3%). The condition was found to be age-dependent in the Japanese squirrels, with 89% of individuals over 4 years of age affected. Mass spectrometry revealed that the C-terminal region of the fibrinogen A alpha-chain was involved in amyloidogenesis in Japanese squirrels as well as humans. No gene variations were identified between amyloid-positive and amyloid-negative squirrels, which contrasted with the available data for humans. The results indicate that fibrinogen A alpha-chain amyloidosis is a senile amyloidosis in Japanese squirrels. The results have also provided comparative pathological support that the amyloidogenic C-terminal region of the fibrinogen A alpha-chain is involved in the characteristic glomerular pathology, regardless of the animal species. This study elucidates the potential causes of death in Japanese squirrels and will contribute to future comparative pathological studies of fibrinogen A alpha-chain amyloidosis.

A new polycipivirus was identified in the arboreal ant Colobopsis shohki. The viral RNA was 11,855 nt in length with five 5'-proximal open reading frames (ORFs) encoding structural proteins and a long 3' ORF encoding the replication polyprotein. The protein sequences of these ORFs had significant similarity to those of the polycipiviruses Lasius niger virus 1 and Solenopsis invicta virus 2. The results of phylogenetic analysis and its genome organization suggested that this virus belongs to the genus Sopolycivirus in the family Polycipiviridae. The name Colobopsis shohki virus 1 (CshV1) is proposed for the new virus.

Invasion by the Argentine ant Linepithema humile (Mayr) (Hymenoptera: Formicidae) causes the collapse of global ecosystems. Attempts to exterminate this invasive ant have mostly been unsuccessful after colonization. However, some attempts are successful when they are applied in the initial stage of invasion, or the invaded area is limited. This indicates that early identification of invasion is crucial for successful extermination. The current methods of identification require special training and skills, suggesting that a new easy and fast method of identification is urgently required. Here, we report a method of identification using a species-specific trail pheromone. The Argentine ant uses (Z)-9-hexadecenal as a trail pheromone. (Z)-9-Hexadecenal is commercially available, because it is used to control the reproduction of a moth (Chilo suppressalis). We applied (Z)-9-hexadecenal 10 cm away from the trails of Argentine ants and 12 native Japanese ant species. The Argentine ant trails were largely disturbed, while the effect on the native Japanese ants was almost undetectable. These results suggest that this trail disruption identification method is an easy and fast method of identifying Argentine ants in Japan and that the effects of this method on native Japanese ants, if any exist, are small.

Dopamine (DA), one of the biogenic amines, has been suggested to regulate the motor activities of various animals. In honey bees, it has been reported to promote locomotor activity in queens, workers, and males, and to regulate the flight activity of workers and males. The role of DA in the flight activity of queens, however, has not yet been investigated. In this study, we tested the roles of DA in the flight activity of virgin queens. We first injected the DA receptor antagonist flupenthixol (10(-2) M or 10(-3) M) into the abdomens of 6-day-old virgin queens and measured the time to flight initiation. The same experiment was performed in workers, to confirm previous findings and compare them to the virgin queens. We then injected 10(-2) M flupenthixol into the queens and quantified their flight activity using a flight mill. The workers were deemed unsuitable for this round of experimentation. In both queens and workers, flupenthixol injection significantly delayed flight initiation. In flight mill experiments, flupenthixol decreased the flight performance of the queens in terms of distance, duration, and velocity. These results suggest the involvement of DA in the flight activity of virgin queens and workers, and indicate that DA is a key neuroactive substance in motor system activation with conserved effects among honey bee queens, workers, and males.

JOURNAL OF INSECT BEHAVIOR

During reproduction, ant colonies produce winged queens. These new queens usually leave the nest to mate and can then establish a new nest. If the new nest is close to an existing colony, it will be in competition with the existing colony. Therefore, workers will kill any mated queens they find outside the colony during the reproductive season. In this study, factors that might determine whether workers eliminate queens were investigated. Mating status (mated or unmated), colony origin (same or different to tested workers) and mating partners (inbred or outbred) of the queens of Japanese harvester ants (Messor aciculatus) were manipulated and the workers' behavior towards the queens was observed. Mated queens were always attacked by workers, though this was not affected by either colony origin or mating partners. These results suggest that mating status triggers elimination of queens by workers, and that the colony origin and mating partner are unlikely to be important roles in elimination of queens.

Fighting and aggression are important tasks for self-preservation in animals. In honey bees, virgin queens fight against each other for survival in a monogynous colony. Because the virgin queens have higher levels of dopamine (DA) in the brain than do mated queens with low aggressiveness, DA may promote fighting and aggression behaviours of virgin queens. In the present study, we investigated the effect of DA on the fighting and stinging response of honey bee virgin queens. We injected two concentrations (10(-3) M and 10(-2) M) of DA and the DA receptor blocker flupenthixol into the abdomen of one-day-old virgin queens and observed fighting and stinging responses. DA injection did not affect fighting and stinging. Injections of 10(-3) M flupenthixol decreased the winning rate significantly, whereas 10(-2) M flupenthixol increased the winning rate, indicating the opposite effects on fighting responses depending on the degrees of blockade of DA signalling. In terms of the stinging response, 10(-2) M flupenthixol-injected virgin queens stung significantly more often than control and 10(-3) M flupenthixol-injected virgin queens. These results suggest an involvement of DA signalling in the regulation of fighting and aggression in virgin queens, although a blockade of DA does not always inhibit these behaviours.

The effect of experience on the behavior of worker bees has been extensively investigated; however, few such studies have been conducted on male bees. Honeybee (Apis mellifera) males (drones), unlike the males of other social hymenopterans, return to their nest after performing a mating flight and have, therefore, an opportunity to learn from their experiences. This provides a chance to understand the significance of experience in social hymenopteran males. Here, we investigated whether experience improves the returning performance in drones (rate and time of return to the hive). We compared the returning performance of ”Experienced” drones that were allowed to fly freely and thus had an opportunity to learn the position of the hive before the experiment with ”Naive” drones that were not allowed to fly and therefore, had no opportunity to learn. We found that Experienced drones returned to the hive after a displacement, whereas Naive drones did not. Furthermore, time to return decreased with the age of drones. These results suggest that flight experience improves the returning performance, which should increase the possibility of mating success and overall colony fitness.
