Optimizing Built Environment in Urban Negative Spaces Using Parametric Methods—Research on a High-Density City in China

Buildings
In the early stage of architectural design, addressing the challenges posed by negative spaces in high-density urban environments is crucial for enhancing spatial efficiency and building sustainability. Multiple studies employed digital methods and tools

Dietary Stress From Plant Secondary Metabolites Contributes to Grasshopper (Oedaleus asiaticus) Migration or Plague by Regulating Insect Insulin-Like Signaling Pathway

Frontiers in Physiology, 2019
Diets essentially affect the ecological distribution of insects, and may contribute to or even accelerate pest plague outbreaks. The grasshopper, Oedaleus asiaticus B-Bienko (OA), is a persistent pest occurring in northern Asian grasslands. Migration and

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Changes in the Range of Four Advantageous Grasshopper Habitats in the Hexi Corridor under Future Climate Conditions

Insects
Angaracris rhodopa (Fischer et Walheim), Calliptamus abbreviatus (Ikonnikov), Myrmeleotettix palpalis (Zubowsky), and Oedaleus decorus asiaticus (Bey-Bienko) are the main grasshoppers that harm the natural grassland in the Hexi Corridor in Gansu ...

Chromosome polymorphisms in natural populations of the South American grasshopper Sinipta dalmani

Genetics and Molecular Biology, 2008
Six populations of Sinipta dalmani from the provinces of Buenos Aires and Entre Rios (Argentina) were analyzed. The populations of "El Palmar" National Park (Entre Rios) were polymorphic for pericentric inversions in pairs M4 and M7 and for a centric ...

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

Physiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Resilience of floral scent emission after florivory

Plant Biology, EarlyView.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Planted grasslands have equivalent or higher arthropod biomass than native grassland important to nesting Sprague's Pipits (Anthus spragueii) early in the breeding season

Restoration Ecology, EarlyView.
Abstract Introduction Grassland species are declining globally. Sprague's Pipit (Anthus spragueii), a native grassland‐obligate, nests in planted grasslands in some regions. How food resources in planted grassland compare with those in native grassland is important to determine the relative benefits of creating new grassland by seeding cropland with ...
