动物行为活跃度及取食偏好对环境丰容中园林植物的影响OA

Implementing environmental enrichment practices helps improve the welfare of captive wildlife.Planting landscape plants in enclo-sures is one of the key approaches to environmental enrichment,contributing to enhanced animal welfare and better exhibit quality.However,the activity levels and feeding preferences of animals may impact the plants within their enclosures.To achieve harmonious coexistence be-tween flora and fauna in zoo exhibits,this study investigates the impact of animal activity levels and feeding preferences on landscape plants in environmental enrichment.It proposes design principles for landscape plants that accommodate animal behavioral patterns,offering a new per-spective for environmental enrichment research in animal enclosures.Findings reveal that the degree of plant damage in environmental enrich-ment is closely correlated with animals'feeding preferences.For instance,plant species highly favored by Trachypithecus germaini,such as Caryota sympetala,Megaskepasma erythrochlamys,Cordyline fruticosa,and Dypsis lutescens,exhibited severe damage.Moderately favored species like Eranthemum pulchellum and Strobilanthes hamiltoniana also sustained significant harm.Additionally,the degree of plant damage in environmental enrichment strongly correlates with animal activity patterns.In high-activity zones of Trachypithecus germaini,landscape plants showed a survival rate of 71.4%and a damage rate of 60.7%,whereas in low-activity zones,survival and damage rates were 100%and 10%,respectively.Based on the activity levels and feeding preferences of Trachypithecus germaini and survival status of landscape plants,the planting recommendations for landscape plants in environmental enrichment within Trachypithecus germaini enclosures have been provided:Recommended species for general planting:Aglaonema modestum and Aspidistra elatior.Suitable for low-activity zones:Megaskepasma erythro-chlamys,Alpinia zerumbet'Variegata',Curculigo capitulata,and Cordyline fruticosa.Unsuitable species:Caryota sympetala,Dypsis lutes-cens,Eranthemum pulchellum,Cordyline fruticosa,and Strobilanthes hamiltoniana.Guided by ethology,scientific enrichment design for zoo enclosures can be developed according to animals'activity levels and feeding preferences,achieving harmonious coexistence between flora and fauna while significantly enhancing animal welfare.
