Here, we present an optimized methodology for producing mycelium-based composites (MBCs) from petrochemicals and polluting materials for thermal insulation applications. To become carbon-neutral and sustainable, biobased and compostable materials like mycelium bio-composite could be the solution. To determine if they meet the construction standards, several experiments were conducted.

This protocol describes a novel three-dimensional (3-D) culture model using a tyramine-linked hyaluronan hydrogel to encapsulate and culture preantral follicles from the mouse ovary. We also detail two approaches to ovarian follicle cryopreservation by vitrification.
FAQs
Placement and accessibility shape how easily animals can approach, pull, manipulate, and consume straw. These design features may alter feeding time, foraging activity, and interactions with the surrounding environment. In housing studies, changing the rack’s position or access conditions helps reveal whether animals receive comparable opportunities to engage in roughage-related behavior.
A straw rack changes the way animals obtain straw by requiring them to pull and manipulate material through a structure. Compared with unrestricted access to a pile, this arrangement can influence the duration and pattern of feeding, foraging activity, and environmental interaction. The comparison is useful when examining how resource-access design affects species-typical behavior.
Accessibility, placement, and construction can influence how animals share access to straw. If the design changes opportunities to approach or retrieve material, animals may show different patterns of interaction around the resource. Behavioral observations can therefore use straw racks to examine competition and how housing arrangements affect access to enrichment or roughage.
By permitting animals to pull, manipulate, and consume straw, a rack can provide opportunities for behaviors associated with natural feeding patterns. Researchers can examine whether animals use these opportunities and how their activity changes under different housing conditions. This makes the structure relevant to behavioral assessments of environmental enrichment and welfare-related activity.
Researchers can include straw racks when comparing housing conditions or resource-access designs. They may examine feeding time, foraging activity, inactivity, environmental interaction, and competition around the resource. Differences in these behaviors help indicate how the availability and arrangement of straw influence animals’ responses to their housing environment.
Evaluation should consider where the rack is placed, how easily animals can reach it, and how its construction shapes access to straw. These conditions may affect feeding activity, resource competition, and the expression of natural behavior. Considering the design together with observed behavior helps relate the structure to welfare and housing outcomes.
