The foraging strategy at abundant resources of the social wasp Vespula germanica includes scanning in the direction of the nest while memorizing resource-specific landmarks and contextual cues.In the present study,we sought to explore wasps'behavioral plasticity on foraging trips to resources whose location and composition changed after a single visit.We evaluated how contextual modifications of food displacement and replacements 60 cm apart from the original site,affect re-orientation for re-finding previously memorized food resources.The results showed that wasps detected and collected the resource faster when more changes were introduced on the following visit.If returning foragers discovered several modifications on both the location and the kind of resource,they collected food more rapidly from the displaced dish,than if only a single parameter in the environment had been changed.These findings illustrate the grade of behavioral plasticity in V.germanica while foraging on abundant resources,which may contribute to the understanding of the prodigious invasive success of this species in anthropized environments.

Background: The drivers of intraspecific variation in behavioral plasticity are poorly known. A widely held hypothesis is that brain size is positively correlated with behavioral plasticity.Methods: A total of 71 Chestnut Thrushes(Turdus rubrocanus) were caught in the wild population. We quantified behavior plasticity of activity of individuals measured in the same cage across two contexts(common and with a novel object stimulation), using a random regression analysis. We then investigated whether head volume(a proxy for brain size) was associated with behavioral plasticity in activity level using Spearman rank-order correlation.Results: We found no significant evidence that activity plasticity was associated with relative head volume. There was no sex difference in head volume or in variance in head volume.Conclusions: We speculate that the absence of an association between brain volume and activity behavior plasticity may result from the inaccuracy of using external skull measurements to estimate brain size, or from a particular part of the brain being responsible for plasticity in activity level.

Neural circuit formation and plasticity are largely dependent on the protein synthesis in the central nervous system. We have shown that newly-synthesized proteins are necessary for the behavioral plasticity in the developing Xenopus tadpoles. The visual avoidance behavior is greatly improved in response to 4 hour visual conditioning at stage 47 tadpoles. In particular, the enhancement of the visual avoidance index is largely blocked by a protein synthesis inhibitor, indicating that newly-synthesized proteins are required for the behavioral plasticity. To determine the identity of the newly-synthesized proteins, the tectal brain was injected with a methionine analogue of Azidohomoalanin（AHA） and tectal brains were homogenized to perform click chemistry reaction and Western blot. We find that the newly-synthesized proteins are significantly increased in the visual conditioned tadpoles compared to the control tadpoles. The increment of newly-synthesized proteins are also observed by the experiment of Dot blot. To screen the identity of newly-synthesized proteins, we combined the technologies of biorthogonal noncanonical amino acid tagging（BONCAT）and the label-free mass spectrometry. We find that hundreds of newly-synthesized proteins are dramatically increased in the visual conditioned optic tecta. It is interesting to find that the synaptic proteins of Rab3 family members of Rab3 a, Rab3 b and Rab3 c are differentially regulated in response to visual conditioning. Rab3 b and Rab3 c are significantly increased, while Rab3 a was dramatically decreased in the visual stimulated tectal brains by Western blot. The functional role of Rab3 family members in the visual experience-dependent behavioral plasticity is to be determined in our following experiments. These data suggested that BONCAT combined with Mass spectrometry largely improves the sensitivity for identifying newlysynthesized proteins in the central nervous system. Rab3 family members may play differential roles in mediating visual experience-dependent behavio

behavioral plasticity has been proposed as a means by which animals alter their phenotypes in response to changing conditions.Animals may display behavioral plasticity as a consequence of environmental variation.The detritus-based,bell-shaped cobweb spider Campanicola campanulata is an ideal model to study behavioral plasticity,because its web architecture is easy to be quantified,and the functions of different parts of the web are clear.Though the plasticity of cobweb architecture has been reported in a few species,retreats as impor-tant defensive structures have rarely been considered before because retreats in most cobwebs are relatively small compared with the web size.We studied the web-building behaviors of C.campanulata under different feeding regimes.We set up 3 spider treatments with different feeding conditions:marginally well fed,moderately well fed,and extremely well fed,and observed the differences in the web architecture among them.In addition,we measured the mechanical properties of anchor silk,and also calculated the foraging and defense investment of the spiders.The results showed that marginally well-fed spiders build cobwebs with significantly longer length of anchor silk,lower retreat to the ground,more number and longer gumfooted lines,and larger capture area,while extremely well-fed spiders build cobwebs with significantly bigger retreat volume and higher height of retreat to the ground.In addition,marginally well-fed spiders invest significantly less during cobweb construction.However,there was no significant difference between the breaking force and elongation at break in anchor silk among different treatments.These results demonstrated that marginally well-fed spiders invest more in foraging,and extremely well-fed spiders invest more in defense,and the spider made a balance between foraging and predator avoidance in response to changes in physiological state.Our study strengthens the current understanding of web construction in cobweb spiders,especially those facing high costs during retr

behavioral plasticity and the underlying neuronal plasticity represent a fundamental capacity of animals to cope with environmental stimuli.behavioral plasticity is controlled by complex molecular networks that act under different layers of regulation.While various molecules have been found to be involved in the regulation of plastic behaviors across species,less is known about how organisms orchestrate the activity of these molecules as part of a coherent behavioral response to varying environments.Here we discover a me chanism for the regulation of animal behavioral plasticity involving molecular sulfation in the brain,a modification of substrate molecules by sulfo transferase(ST)-catalyzed addition of a sulfonate group(SO3)from an obligate donor,3’-phosphoadenosine 5’-phosphosulfate(PAPS) to the substrates.We investigated aggregation behaviors of migratory locusts,which are well-known for extreme phase change plasticity triggered by population density.The processes of PAPS biosynthesis acted efficiently on induction of locust behavioral transition:Inhibition of PAPS synthesis solicited a behavioral shift from gregarious to solitarious states;external PAPS dosage,by contrast,promoted aggregation in solitarious locusts.Genetic or pharmacological intervention in the sulfation catalyzation resulted into pronounced solitarizing effects.Analysis of substrate-specific STs suggests a widespread involvement of sulfated neurotransmitters in the behavioral response.D opamine in the brain was finally identified to be actively sulfate conjugate d,and the sulfate conjugation enhanced the free DA-mediated behavioral aggregation.Similar results in Caenorhabditis elegans and mice indicate that sulfation may be involved more broadly in the modulation of animal aggregation.These findings reveal a general me chanism that effectively regulates animal social-like behavioral plasticity,possibly through sulfation-mediated modification of neural networks.

Native animals are facing long-term coexistence with invasive plants worldwide,the impacts of which on animal behavior remain poorly known.Potential ecological traps could threaten native birds breeding in invasive plant habitats,but behavioral strategies for birds to avoid such risks are few concerned.The invasion of Smooth Cordgrass(Spartina alterniflra) has seriously varied the vegetation landscape in the coastal wetlands of eastern China,and affected the habitat selection of native birds.Here,we investigated the nesting and breeding characteristics of a common native passerine,the Vinous-throated Parrotbill(Sinosuthora webbiana),in habitats dominated by native Common Reed(Phragmites australis) and exotic cordgrass.We found that parrotbills could complete their breeding cycle in cordgrass habitat.Most nest failure was attributed to predation in native habitat but tide inundation in cordgrass habitat.However,the nest success rate and daily survival rate(DSR) in cordgrass habitat were higher.Moreover,nest height was markedly higher in cordgrass habitat and was the most important influencing variable(positively correlated with the DSR).These results suggest that cordgrass habitat is a potential ecological trap due to the tide inundation,but some parrotbills seem to effectively avoid this risk by increasing nest height.Our study reveals that a native passerine changes its nesting behavior to accommodate invasive plant habitat and highlights that habitat changes caused by invasive plants may drive the adaptive evolution of native animal behavior.The limitation of these results must be acknowledged for the small sample size,and there is a need for a larger sample and long-term data for further verification.

Rapid advances in Ribonucleic Acid sequencing(or RNA-seq)technology for analyzing entire transcriptomes of desired tissue samples,or even of single cells at scale,have revolutionized biology in the past decade.Increasing accessibility and falling costs are making it possible to address many problems in biology that were once considered intractable,including the study of various social behaviors.RNA-seq is opening new avenues to understand long-standing questions on the molecular basis of behavioral plasticity and individual variation in the expression of a behavior.As whole transcriptomes are examined,it has become possible to make unbiased discoveries of underlying mechanisms with little or no necessity to predict genes involved in advance.However,researchers need to be aware of technical limitations and have to make specific decisions when applying RNA-seq to study social behavior.Here,we provide a perspective on the applications of RNA-seq and experimental design considerations for behavioral scientists who are unfamiliar with the technology but are considering using it in their research.

Superior species may have distinct advantages over subordinates within asymmetrical interactions among sympatric animals.However,exactly how the subordinate species coexists with superior species is unknown.In the forests west of Beijing City,intense asymmetrical interactions of food competition exist among granivorous rodents(e.g.Apodemus peninsulae,Niviventer confucianus,Sciurotamias davidianus and Tscherskia triton)that have broadly overlapping habitats and diets but have varied body size(range 15-300 g),hoarding habits(scatter vs larder)and/or daily rhythm(diurnal vs nocturnal).The smallest rodent,A.peninsulae,which typically faces high competitive pressure from larger rodents,is an ideal model to explore how subordinate species coexist with superior species.Under semi-natural enclosure conditions,we tested responses of seed-hoarding behavior in A.peninsulae to intraspecific and interspecific competitors in the situations of pre-competition(without competitor),competition(with competitor)and post-competition(competitor removed).The results showed that for A.peninsulae,the intensity of larder-hoarding increased and the intensity of scatter-hoarding declined in the presence of intraspecifics and S.davidianus,whereas A.peninsulae ceased foraging and hoarding in the presence of N.confucianus and T.triton.A.peninsulae reduced intensity of hoarding outside the nest and moved more seeds into the nest for larder-hoarding under competition from intraspecific individuals and S.davidianus.In most cases,the experimental animals could recover to their original state of pre-competition when competitors were removed.These results suggest that subordinate species contextually regulate their food-hoarding strategies according to different competitors,promoting species coexistence among sympatric animals that have asymmetrical food competition.

Marine invertebrates that move too slowly to evade unfavorable environmental change may instead exhibit phenotypic plasticity,allowing them to adjust to varying conditions.The orange-footed sea cucumber Cucumaria frondosa is a slow-moving suspension feeder that is preyed on by the purple sunstar Solaster endeca.The sea cucumber's antipredator behavior involves changing shape and detaching from the substratum,which might increase its probability of being displaced by water motion into an unsuitable environment.We hypothesized that sea cucumbers'antipredator responses would be diminished under stronger hydrodynamic forces,and that behavioral strategies would be flexible so that individuals could adjust to frequent changes in water flows.In a natural orange-footed sea cucumber habitat,individuals lived along a pronounced hydrodynamic gradient,allowing us to measure antipredator behavior under different water flow strengths.We placed purple sunstars in physical contact with sea cucumbers living at various points along the gradient to elicit antipredator responses.We then repeated this procedure in a laboratory mesocosm that generated weak and strong hydrodynamic forces similar to those observed at the field site.Subjects in the mesocosm experiment were tested in both wave conditions to determine if their antipredator behavior would change in response to sudden environmental change,as would be experienced under deteriorating sea conditions.Antipredator responses did not covary with hydrodynamic forces in the field.However,antipredator responses in the mesocosm experiment increased when individuals were transplanted from strong to weak forces and decreased when transplanted from weak to strong forces.Overall,our results indicate environmentally induced plasticity in the antipredator behavior of the orange-footed sea cucumber.

Habitats are characterized by different local environmental conditions that inﬂuence both behavior and morphology of species,which can result in habitat-dependent phenotypic differences among animals living in heterogeneous environments.We studied 3 alpine populations of Eurasian red squirrels(Sciurus vulgaris),1 living in a marginal high-elevation habitat at the edge of the species’altitudinal distribution,and 2 occurring in higher-quality habitats.Here,we investigated whether squirrels living in the marginal area differed in 2 morphological parameters(body size and body mass)and/or in the expression of 4 personality traits estimated with an openﬁeld test and a mirror image stimulation test(activity,exploration,activity-exploration,and social tendency).Furthermore,we tested whether within-individual variance of the traits(behavioral plasticity)was higher in the edge habitat.Male squirrels in the edge habitat were smaller and weighed less than in the other study areas,while among females,size–habitat relationships were less marked.These sex-speciﬁc patterns were explained by a strong association between body mass and reproductive success in female squirrels.Squirrels in the marginal habitat were more active,explorative,and had a more social personality than in the other habitats.However,in contrast to our predictions,behavioral plasticity was smaller in the marginal habitat,but only for the trait exploration.Our results suggest that animals choose the habitat that bestﬁts their personality,and that habitat-related differences in selective pressures may shape animals’morphology.
