Summary: This study evaluated the potential effects of low concentration lead stress on the development and reproduction of Aleuroglyphus ovatus. The results showed that lead stress had both accelerating and retarding effects on the mite's development, with greater inhibitory effects at higher lead concentrations. Lead stress also significantly prolonged the immature stages of A. ovatus. Oviposition periods were longer in treatments with lower lead concentrations and shorter in treatments with higher lead concentrations. The survival rate and net reproduction rate of treated A. ovatus decreased with increasing lead concentrations.

Summary: Caterpillars and pupae are important sources of evidence for identifying primitive moths, and Incurvariidae is recognized as one of the most primitive group of extant Lepidoptera. The study introduces the immature stages, including caterpillar and pupa, of the monotypic genus Subclemensia within Incurvariidae for the first time, along with biological characteristics and DNA barcoding. This contributes to enhancing the understanding of the family's immature stages and stabilizing the generic nomenclature.

Summary: The study utilized DNA barcoding to explore species diversity in the Neotropical butterfly genus Hermeuptychia, revealing 45 potential species compared to the current taxonomy's recognition of 11 species. Comparative analysis showed that the Automatic Barcode Gap Discovery (ABGD) method was more reliable and plausible in delineating species boundaries.

Summary: This study describes the morphology and chaetotaxy of larvae and pupae of Phloeosinus tacubayae, determines the number of larval instars, sexual dimorphism in adults, and development time. The results reveal unique attributes in the body of P. tacubayae larvae compared to other genera in the subfamily, and provide useful morphological characters for identifying sexual dimorphism in adults. The development time of P. tacubayae lasts for 40 days, with the pupal stage taking the longest.

Summary: We report the immature stages and natural host plants of three species in the Taygetis clade of the Euptychiina subtribe. The study was conducted in Peru, and we found that Taygetis echo feeds on Olyra latifolia, Taygetis sosis feeds on Pariana lunata, and Pseudodebis valentina feeds on Guadua weberbaueri. We provide descriptions, photos, and illustrations of the immatures and host plants for each species.

Summary: The study compared the gene expression levels of newly established symbiotic hydra, native symbiotic hydra, and non-symbiotic hydra, revealing upregulation of lysosomal enzymes and downregulation of genes related to nematocyte development in symbiotic strains. Translation and respiratory chain genes were upregulated only in the newly established symbiotic strain. Treatment with rapamycin, inhibiting translation, induced degeneration in both symbiotic strains, particularly severe in the newly established strain. Results suggest that balancing cellular metabolism between host and symbiont is crucial for adapting to endosymbiosis with Chlorococcum.

Summary: Interactions between developing T cells and Aire(+) medullary thymic epithelial cells are crucial for central tolerance induction in the thymus. Self-reactive CD4(+) thymocytes control the transcriptional regulators and composition of mTEC(lo) subsets, including Aire(+) mTEC(hi) precursors, post-Aire and tuft-like mTECs. These interactions upregulate the expression of tissue-restricted self-antigens, cytokines, chemokines, and adhesion molecules important for T-cell development. Our study reveals that self-reactive CD4(+) thymocytes control multiple facets of immature mTECs, determining their heterogeneity.

Summary: This study shows that warning patterns of Heliconius butterflies act as both aposematic signals and mating cues. Visual attraction differences among individuals explain low-level assortative mating. Additionally, ecological mating cues' contribution to reproductive isolation may depend on immediate sensory conditions.

Summary: The detailed descriptions of immature stages of Lachnaeus crinitus, Rhinocyllus alpinus, and R. conicus belonging to Lixini (Curculionidae: Lixinae) provide valuable insights into the relationship between species and the taxonomic and phylogenetic value of the tribes and genera in the Lixinae. It is highlighted that the morphology of immature stages, often overlooked, plays a crucial role in identifying new characters for clarifying taxonomical and phylogenetic complexities based on adult studies only.

Summary: The biology of Holotrichia longipennis and Holotrichia sikkimensis was studied in north western Himalaya and their immature stages were described. The average length and width of newly laid eggs of H. longipennis were 1.41 x 1.10 mm, while for H. sikkimensis it was 2.16 x 1.18 mm. The larvae of H. longipennis had three instars with body lengths of 10.22, 23.48, and 36.59 mm, and head capsule widths of 1.74, 3.48, and 5.06 mm, respectively. The larvae of H. sikkimensis had body lengths of 11.53, 24.86, and 36.12 mm, and head capsule widths of 1.82, 3.98, and 5.15 mm for the three instars, respectively.

Summary: Plant secondary chemistry influences plant-insect community structure; phytochemical diversity plays a role in shaping the variation in plant secondary chemistry and its impact on community structure. Both compositional and structural dimensions of PD affect herbivory, caterpillar biodiversity, and plant-herbivore network structure at different scales, indicating that PD has distinct roles across biological organization scales.

Summary: Understanding the response of biodiversity to environmental changes requires linking local and regional ecological and evolutionary processes. In this study, we integrated evolution and mutualistic coevolution in a model of metacommunity dynamics and conducted numerical simulations to examine the effects of coevolution on species distribution and persistence. Our results demonstrate that coevolution and species richness synergistically shape distribution patterns by enhancing colonization and reducing extinction in metacommunities. Coevolution increases trait matching among mutualists at the landscape scale, counteracting local maladaptation and facilitating colonization and range expansions. Furthermore, coevolution buffers the effects of environmental changes, preventing species extinctions and metacommunity collapse. These findings elucidate the mechanisms by which coevolution promotes persistence under environmental changes, particularly in diverse systems with landscape connectivity.

Summary: This study examined the impact of five vegetation types on butterfly assemblages at a small scale in the Southern Amazon region. It found that different vegetation types influenced the composition and diversity of butterfly communities. The differences may be due to factors such as light levels, temperatures, humidity, and host plant availability. The results suggest that the presence of various vegetation types in the region promotes the coexistence of butterfly species and conservation efforts should address specific threats to each vegetation type.

Summary: Recent studies suggest that changes in fire regimes pose a significant threat to global biodiversity in the 21st century. To accurately identify species most at risk from fire, it is important to consider their physiological, ecological, and evolutionary traits along with their local fire exposure. A framework was developed to assess vulnerability to fire-induced stress in the Brazilian savanna, incorporating exposure (frequency, extent, and magnitude of fire) and sensitivity (biological, physiological, and behavioral traits). The Fire Vulnerability Index (FVI) categorizes species into four groups based on their vulnerability, from extremely vulnerable to least vulnerable, highlighting the need for a broader assessment method considering both traits and local fire exposure.

Summary: Ecological interactions are vital for maintaining biodiversity on Earth. This study investigates the impact of direct and indirect effects in mutualistic networks, showing that indirect effects play a major role in determining species fitness. Indirect effects prevent coevolving species from adapting to their mutualistic partners and other environmental pressures, resulting in decreased fitness. The topological effect of peripheral species experiencing more indirect effects and greater reduction in fitness compared to central species is evident. The study also highlights how honeybees as a central species in pollination networks increase indirect effects, thus reducing the fitness of other species.
