Apoptosis is not only pivotal for development, but also pathogen defence in multicellular organisms. Although numerous intracellular pathogens are known to interfere with the host’s apoptotic machinery overcome this defence, its importance host-parasite coevolution has been neglected. We conducted three inoculation experiments investigate respond during infection gut Nosema ceranae, which considered as potential global threat honeybee (Apis mellifera) and other bee pollinators, sensitive...
Ecuador belongs to the megadiverse countries of world. However, high diversity in species, ecosystems and their services are under threat by land use changes, invasive overexploitation, pollution climate change. There is a need monitor, manage, protect improve biodiversity ecosystem (BES) Ecuador; however, marginally represented international policy-science interface for protection BES. We analyzed 266 peer-reviewed papers that were published between 2000 2020 assess current impact human...
Determining how ant colonies optimize foraging while mitigating pathogen and predator risks provides insight into the ants have achieved ecological success. Ants must respond to changing resource conditions, but exploration comes at a cost of higher potential exposure threats. Fungal infected cadavers surround main trails carpenter Camponotus rufipes, offering system study foragers behave given persistent occurrence disease Studies on social insect behavior typically require many hours human...
We provide the first genetic sequence data for a Dipylidium species from wild carnivore plus an analysis of effects ecological, demographic, physiological and behavioural factors on sp. infection prevalence in social carnivore, spotted hyaena (Crocuta crocuta), Serengeti National Park, Tanzania. Our mitochondrial gene fragment (1176 base pair long) had similarity between 99% 89% to caninum. determined 146 faecal samples 124 known animals three groups (termed clans) using molecular screening...
Urbanization is a global phenomenon that can affect fitness and could challenge the persistence of most species, including wild bee pollinators. Yet, how which environmental features health within urban ecosystem remain unclear. Here, we placed experimental Bombus terrestris colonies in sites spanning from edge into city's core to investigate bumble parasitism, foraging behaviour, energetic stress, colony growth reproductive output. In each site, ambient temperature was recorded,...
A. dorsata builds its large exposed comb high in trees or under ledges of rocks. The "open" nest dorsata, shielded (only!) by multiple layers bees, is highly vulnerable to any kind direct contact close range attacks from predators. Therefore, guard bees the outer layer dorsata's monitor vicinity for possible hazards and an effective risk assessment required. Guard however, are frequently different objects like leaves, twigs other tree litter passing above falling ground. Thus, downward...
Abstract Insect populations are declining globally. A major driver of this decline is land use change, including urbanisation. However, urban environments can also offer a wide range floral resources to pollinators, through ornamental plantings, but these vary widely in their attractiveness insects. Often, the largest single planter plants an area municipality. Here we evaluated decorative plantings carried out by city municipality Regensburg, Germany, systematically surveying insect...
Abstract Bumble bees and honey provide crucial pollination service have become important insect model system. Despite their close relation, they differ in morphology, physiology, social organisation. Notably, workers exhibit age-based polyethism, while bumble display considerable body size variation. Though is known to affect foraging range, behaviour, flight ability, the influence of age remains less explored. Here we studied performance (distance speed) aging bee using tethered mills....

Deep learning (DL) based detection models are powerful tools for large-scale analysis of dynamic biological behaviors in video data. Supervised training a DL model often requires large amount manually-labeled data which time-consuming and labor-intensive to acquire. In this paper, we propose LFAGPA (Learn From Algorithm-Generated Pseudo-Annotations) that utilizes (noisy) annotations automatically generated by algorithms train ant videos. Our method consists two main steps: (1) generate...
Abstract Determining how ant colonies optimize foraging while mitigating disease risk provides insight into the ants have achieved ecological success. Fungal infected cadavers surround main trails of carpenter Camponotus rufipes , offering a system to study foragers behave given persistent occurrence threats. Studies on social insect behavior typically require many hours human labor due high density individuals. To overcome this, we developed deep learning based computer vision algorithms...
