Garden-based learning (GBL) curricula represents a pedagogy that increases student exposure to nature and connects them to engaging activities for higher classroom achievement. GBL is proposed to enhance student science self-perceptions, engagement, and desired outcomes in science learning and identity by connecting students to relatable, hands-on, and authentic learning experiences through a felt sense of place. Saint Louis Metro Area K-12 science educators were asked to describe their students' self-perceptions, engagement, and outcomes in science and possible teaching experiences with GBL. Experienced Saint Louis Metro Area garden educators offer authentic, hands-on activities that increase feelings of belonging, competence, and autonomy in science. GBL strongly encourages positive behavioral and emotional student interactions with science lessons by providing an outdoor space that hosts exciting and relatable topics that expand students' perceptions of their local environment, community, and themselves.

Our non-Black colleagues must fight anti-Black racism and white supremacy within the academy to authentically promote Black excellence. Amplifying Black excellence in ecology and evolution is the antidote for white supremacy in the academy.

Abstract: Purpose: To report ophthalmic examination findings and intraocular pressures (IOPs) in wild‐caught African giant pouched rats (Cricetomys ansorgei and gambianus) from Tanzania and Ghana. Procedures: After being placed under general anesthesia for examination, slit‐lamp biomicroscopy before and after pharmacologic mydriasis and indirect ophthalmoscopy was performed. Eyes were fluorescein stained and IOPs measured by rebound tonometry using the TonoVet®. Results: Thirty‐two sexually mature pouched rats (64 eyes) were examined, including 16 males and 16 females. The mean IOP (± standard deviation) was 7.7 (±2.9) mmHg. Fluorescein staining was negative in all eyes. One or more ocular abnormalities were detected in 21 pouched rats (35 eyes). These ocular lesions included the following: lens opacities (n = 23 eyes), persistent pupillary membranes (n = 5), chorioretinal scarring (n = 3), corneal vascularization (n = 2), palpebral margin defect with focal trichiasis (n = 2), phthisis bulbi (n = 1), and posterior synechiae (n = 1). Lens opacities included incipient anterior cortical opacities (n = 7), immature cataract (n = 6), incipient nuclear opacities (n = 5), punctate pigment on anterior lens capsule (n = 2 eyes), incipient suture tip opacities (n = 2), and hypermature cataract (n = 1). Conclusions: Ocular abnormalities were common in the evaluated population of giant pouched rats; however, most of the detected lesions were mild and believed to have minimal impact on vision. Rebound tonometry with the TonoVet® was a reliable and simple technique to measure IOPs in the anesthetized pouched rats. [ABSTRACT FROM AUTHOR]

African giant pouched rats (Cricetomys spp.) are large rodents native to subSaharan Africa. Wild-caught pouched rats identified as Cricetomys ansorgei (n = 49) were imported from Tanzania. A survey of gastrointestinal parasitism by fecal flotation revealed the presence of multiple parasites, including Nippostrongylus spp., Heterakis spp., Trichuris spp., Hymenolepis spp., Raillietina spp., and Eimeria spp. Oral self-administered fenbendazole (150 ppm), topical moxidectin (2 mg/kg), pyrantel pamoate (15 mg/kg), piperazine (100 mg/kg daily), and injectable ivermectin (0.25 mg/kg) were used to determine effective treatment options for the gastrointestinal parasites present in the colony. Pyrantel pamoate in a treat vehicle and piperazine in water bottles were easily administered and significantly reduced the numbers of animals shedding Nippostrongylus spp. and Heterakis spp. during the study. Moxidectin and ivermectin were clinically ineffective at reducing fecal egg shedding. Fenbendazole was most effective at clearing infection with Trichuris spp. Although 10 mg/kg praziquantel was ineffective, a single dose of 30 mg/kg praziquantel significantly reduced the number of African pouched rats that shed cestode embryos. A combination treatment may be necessary to successfully treat all parasites present in any given animal.
