Megaherbivore carcasses represent sporadic but energetically rewarding resources for carnivores, offering a unique opportunity to study coexistence dynamics between facultative scavengers. South African fenced protected areas, such as Madikwe Game Reserve (Madikwe hereafter), host viable populations of large carnivores and high densities of elephants, . However, high carnivore densities can lead to potentially fatal interspecific encounters and increased competition, particularly around high-quality trophic resources.

Methods: This retrospective analysis compared two cohorts of patients undergoing lens replacement surgery with bilateral implantation of the Tecnis ICB00 or the Tecnis ZCB00 IOL (383 patients in each group). Monocular and binocular uncorrected distance (UDVA), intermediate (UIVA; 66cm), and near (UNVA; 40cm) visual acuities, refractive predictability, and patient-reported outcomes were compared.
Mammals in arid zones have to trade off thermal stress, predation pressure, and time spent foraging in a complex thermal landscape. We quantified the relationship between the environmental heat load and activity of a mammal community in the hot, arid Kalahari Desert. We deployed miniature black globe thermometers within the existing Snapshot Safari camera trap grid on Tswalu Kalahari Reserve, South Africa.

Setting: Private clinics, United Kingdom.
Design: Retrospective case series.
Purpose: To evaluate early clinical outcomes and adverse events (AEs) in cataract patients following implantation of a monofocal hydrophobic acrylic IOL with a new optimized non-constant aberration-correcting design (CT LUCIA 621P).
Methods: This retrospective study included patients with visually significant cataracts who underwent implantation of the CT LUCIA 621P IOL. Refraction, corrected (CDVA) and uncorrected (UDVA) visual acuity of the last available visit were used in the analysis.
Purpose: To compare refractive, visual, and patient-reported outcomes associated with a 1st generation wavefront-guided (WFG) treatment with those associated with a 3rd generation WFG treatment.
Patients And Methods: This retrospective study included patients who underwent femtosecond laser-assisted in situ keratomileusis (LASIK) for myopia/myopic astigmatism. Two random stratified samples of patients who underwent either 1stgeneration (WaveScan, Johnson & Johnson Vision, Santa Ana, CA) or 3rd generation (iDesign 2.
Carnivora occupy many ecological niches fundamental to ecosystem functioning. Within this diverse order, carnivore species compete to establish dominance, ensure survival and maintain fitness. Subordinate carnivores must, therefore, adapt their behaviour to coexist with dominant species.

Decisions on how best to manage such wildlife are ideally informed by regular and reliable estimates of spatiotemporal fluctuations in population size and structure. However, even in small, fenced areas, it is difficult and costly to regularly monitor key species using advanced methods.
View Article and Find Full Text PDFPurpose: To evaluate outcomes and the incidence of adverse events (AEs) in patients who underwent bilateral same-day refractive lens exchange (RLE).
Design: Retrospective case series.
Participants: Patients of a private intraocular surgery provider in the United Kingdom who underwent RLE in both eyes on the same day with treatment dates between March 2018 and December 2021.
Purpose: To evaluate clinical and subjective outcomes of a segmented bifocal IOL with a 2.0 D near addition.
Patients And Methods: Retrospective analyses of patients who had undergone refractive lens exchange with bilateral implantation of the SBL-2 IOL (Lenstec, Inc.
Seabird populations experience predation that can impact their breeding density and breeding success. The Cape gannet is endemic to the Benguela upwelling ecosystem and is classified as Endangered by the IUCN. They are affected by several threats, including predation by the Cape fur seal .

Setting: Private practice, United Kingdom.
Design: Retrospective case series.
Purpose: To evaluate clinical outcomes 1 year after implantation of an extended depth of focus intraocular lens (IOL) in a large series of patients.
Methods: Outcomes of patients who underwent refractive lens exchange or cataract surgery with the implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG) were retrospectively reviewed. The near (40 cm), intermediate (66 cm), and distance visual acuity, refractive outcomes, and cumulative rate of adverse events and secondary procedures were evaluated at 12 months postoperatively.
Purpose: To identify independent factors associated with postoperative satisfaction after refractive lens exchange with an extended depth of focus intraocular lens (EDOF IOL).
Methods: Patients who underwent a refractive lens exchange with bilateral implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec, Jena, Germany) and attended the 3-month follow-up visit were included in the analysis (N = 351 patients). Demographics, preoperative and postoperative clinical parameters, and patient-reported outcomes were used in a regression model to determine predictors of 3-month postoperative satisfaction.
Purpose: To describe our technique of sub-Tenon's anesthesia and report adverse events and patient comfort.
Setting: Optical Express, United Kingdom.
Design: Retrospective case series.
The subtle and cascading effects (e.g., altered interspecific interactions) that anthropogenic stressors have on local ecological assemblages often go unnoticed but are concerning given their importance in ecosystem function.

Methods: Setting: Private refractive surgery clinics.
Purpose: To evaluate clinical and patient-reported outcomes of a new extended depth of focus intraocular lens (IOL).
Methods: Data of patients treated between September 2017 and September 2018 who underwent a refractive lens exchange/cataract surgery with an implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG, Jena, Germany) and attended the 1-week, 1-month, and 3-month follow-up visit were reviewed.

Purpose: To compare refractive and visual outcomes, patient satisfaction, and complication rates among different age categories of patients who underwent refractive lens exchange (RLE).
Methods: A stratified, simple random sample of patients matched on preoperative sphere and cylinder was selected for four age categories: 45-49 years (group A), 50-54 years (group B), 55-59 years (group C), and 60-65 years (group D). Each group contained 320 patients.
