Data from: Translocation strategies for multiple species depend on interspecific interaction type
Conservation translocations – anthropogenic movements of species to prevent their extinction – have increased substantially over the last few decades. Although multiple species are frequently moved to the same location, current translocation guidelines consider species in isolation. This practice ignores important interspecific interactions, and thereby risks translocation failure. We model three different two-species systems to illustrate the inherent complexity of multi-species translocations, and to assess the influence of different interaction types (consumer-resource, mutualism, and competition) on translocation strategies. We focus on how these different interaction types influence the optimal founder population sizes for successful translocations, and the order in which the species are moved (simultaneous or sequential). Further, we assess the effect of interaction strength in simultaneous translocations, and the time delay between translocations when moving two species sequentially. Our results show that translocation decisions need to reflect the type of interaction. While all translocations of interacting species require a minimum founder population size, which is demarked by an "extinction boundary", consumer-resource translocations also have a maximum founder population limit. Above the minimum founder size, increasing the number of translocated individuals leads to a substantial increase in the extinction boundary of competitors and consumers, but not of mutualists. Competitive and consumer-resource systems benefit from sequential translocations; but the order of translocations does not change the outcomes for mutualistic interaction partners noticeably. Interspecific interactions are important processes that shape population dynamics, and should therefore be incorporated into the quantitative planning of multispecies translocations. Our findings apply whenever interacting species are moved, for example, in reintroductions, conservation introductions, biological control or ecosystem restoration.
Calcium concentration regulates interspecific interaction of algae along the nutrient gradient
<p><span>Although many studies have focused on the influence of </span><span>abiotic stress gradient</span><span>s on biological interactions, few studies explained the effects of both resource and non-resource stress gradients on the facilitation between species.</span><span> We conducted a controlled experiment to study the effects of nutrient stress gradient on the interspecific relationship between <em>Phormidium corium</em> and <em>Scenedesmus quadricauda</em> under different calcium concentration. The results showed that when the calcium concentration was high, the change of interspecific relationship between the two algae along the nutrient stress gradient accorded with the SGH theory, that is, the competitive interaction changed into positive interaction. The reason for this phenomenon may be that in the stress environment, the population density is low and the encounter rate is low; secondly, facilitation may improve the harsh environment and make it more beneficial to the beneficiary species, which may enable the beneficiary species to survive in the environment that they could not survive before. When the calcium concentration was low, the change of interspecific relationship along resource stress was in line with the "Hump hypothesis", that is, facilitation reached the peak under medium resource stress. This phenomenon may be caused by the interaction between salt stress and nutrient. When calcium stress was high, it may not be conducive to the absorption of nutrients by algae, resulting in the fierce competition for limited resources in the harsh environment. While the facilitation effect may be strongest in the medium stress environment due to the relatively sufficient resource. These results emphasized the joint effects of various stress factors on interspecific relationships, especially the importance of non-resource stress in the study of community composition, pointed out a new direction for the study of facilitation, and provided theoretical guidance for the prevention and control of freshwater blooms.</span></p>

Data from: An assessment of phylogenetic tools for analyzing the interplay between interspecific interactions and phenotypic evolution
Much ecological and evolutionary theory predicts that interspecific interactions often drive phenotypic diversification and that species phenotypes in turn influence species interactions. Several phylogenetic comparative methods have been developed to assess the importance of such processes in nature; however, the statistical properties of these methods have gone largely untested. Focusing mainly on scenarios of competition between closely-related species, we assess the performance of available comparative approaches for analyzing the interplay between interspecific interactions and species phenotypes. We find that many currently used statistical methods often fail to detect the impact of interspecific interactions on trait evolution, that sister-taxa analyses are particularly unreliable in general, and that recently developed process-based models have more satisfactory statistical properties. Methods for detecting predictors of species interactions are generally more reliable than methods for detecting character displacement. In weighing the strengths and weaknesses of different approaches, we hope to provide a clear guide for empiricists testing hypotheses about the reciprocal effect of interspecific interactions and species phenotypes and to inspire further development of process-based models.

Data from: Spatial distribution of flower color induced by interspecific sexual interaction
Understanding the mechanisms shaping the spatiotemporal distribution of species has long been a central concern of ecology and evolutionary biology. Contemporary patterns of plant assemblies suggest that sexual interactions among species, i.e., reproductive interference, lead to the exclusive distributions of closely related species that share pollinators. However, the fitness consequences and the initial ecological/evolutionary responses to reproductive interference remain unclear in nature, since reproductive isolation or allopatric distribution has already been achieved in the natural community. In Japan, three species of blue-eyed grasses (Sisyrinchium) with incomplete reproductive isolation have recently colonized and occur sympatrically. Two of them are monomorphic with white flowers, whereas the other exhibits heritable color polymorphism (white and purple morphs). Here we investigated the effects of the presence of two monomorphic species on the distribution and reproductive success of color morphs. The frequency and reproductive success of white morphs decreased in area where monomorphic species were abundant, while those of purple morphs did not. The rate of hybridization between species was higher in white morphs than in the purple ones. Resource competition and habitat preference seemed not to contribute to the spatial distribution and reproductive success of two morphs. Our results supported that color-dependent reproductive interference determines the distribution of flower color polymorphism in a habitat, implying ecological sorting promoted by pollinator-mediated reproductive interference. Our study helps us to understand the evolution and spatial structure of flower color in a community.
