Abstract

Livestock keeping forms main occupation in arid and semi-arid lands. Increase in drought frequency and intensity globally negatively affect livestock production and livelihood. Cattle are the most drought sensitive livestock due to size, grazing behavior and nutritional requirements. Factors for vulnerability of cattle to droughts are individual cattle parameters, health and husbandry practices. This cross sectional study aimed to those factors in semi-arid Kaloleni sub-county. Data on household (HH) head demographics, cattle and production collected from 194 enrolled HH using structured questionnaires. Cattle ages were grouped into young (<1 year old), growers (1-2 years old) and adults (>2years old). Data was analyzed using STATA 12 software. Univariate, bivariate and multivariate logistic regression analysis conducted and reported in Crude Odds Ratio (cOR), Adjusted Odds Ratio (aOR) and Confidence Interval (CI). We used Pearson product-moment correlation to determine relationship between HH head, cattle herd, individual cattle characteristics and drought characteristics, p = <0.05 being significant. Mean age HH heads was 40.7 {+/-} 12.6 years, 44.3% (86) had basic education, males were 65.3% (n=126). Mixed livestock production was practiced by 69.1% (134), while 86.1% (167) practiced free range communal grazing. Adult cattle were 54.1% (1295). Female cattle were 72.7% (1741). Average body condition score was 3.0 {+/-} 0.6, and calves had 2.6 {+/-} 1.3. About 20.6% had various forms of illness, calves mostly affected at 29.1%. Up to 63.4% HH, spray cattle at home, 93.3% HH reported no vaccination history. Home straying was protective (cOR 0.3, 95% CI 0.14 - 0.53). Herd size (aOR 2.9, 95% CI 1.5 - 5.5) and having no disease control method (aOR 2.8, 95% CI 1.85 - 9.19) were contributing to reporting disease. We report positive correlation between drought outcomes and HH head (r=0.076, p>0.01), cattle herd (r=0.216, p=0.003 and individual cattle characteristics(r=0.139, p>0.01). The findings on cattle conditions exacerbate their vulnerability in presence of stressful conditions like droughts especially in calves and cows. This study demonstrates weak disease control efforts and unorganized husbandry practices. We propose strategic and focused disease control plans to improve cattle resilience and further research on livestock based factors as drought response metrics for the livestock livelihood.

Beyond Single-Metric Assessments: Uncovering Masked Butterfly Declines via Multi-Scalar Analysis in Central Alberta

1. This study analyzed 21 years (2000-2025) of butterfly count data from Central Alberta, integrated with intensive 5-year (2021-2025) high-resolution intra-seasonal sampling. 2. Long-term macro-scale analysis revealed a significant decline in Shannon Diversity, a change that remained obscured when relying solely on traditional metrics of species richness and evenness. 3. This diversity decline was primarily driven by the severe, long-term collapse of the native Common Ringlet (Coenonympha tullia). 4. Four other dominant species--Cabbage White (Pieris rapae), Clouded Sulphur (Colias eriphyle), European Skipper (Thymelicus lineola), and Common Wood Nymph (Cercyonis pegala)--maintained long-term population stability, though their abundances were significantly constrained by extreme winter minimum temperatures and rapid spring warming. 5. High-resolution intra-seasonal analysis (2021-2025) demonstrated that community indices and species-specific abundances were strongly limited by daily weather, particularly wind velocity and temperature. 6. These findings illustrate that while traditional metrics like richness and evenness are fundamental to community ecology, they provide incomplete insights when applied in isolation; they are most effective when utilized as part of a complementary, multi-scalar framework. 7. This study highlights the necessity of coupling multi-decadal historical datasets with high-frequency, fine-scale sampling to accurately identify the mechanisms of community turnover that simpler metrics may overlook. 8. The results underscore the critical importance of standardized citizen science monitoring in quantifying environmental impacts and establishing conservation priorities for terrestrial insect groups.

From concentration to export: resource contrasts and bee traits shape pollinator spillover to crops

Floral plantings can either concentrate bees or export them to adjacent crops, yet the ecological conditions influencing these outcomes remain unclear. Here, we develop a mathematical model as proof of concept for our previous integrative hypothesis: concentrator and exporter outcomes can arise as alternative, context-dependent outcomes of the same underlying resource-selection process. Using bees as a model and focusing specifically on spillover from floral plantings to crops, we identified resource-specific thresholds separating concentration- and export-favoring conditions. Our model translates differences in relative patch attractiveness into context-dependent concentration and export outcomes and generates resource-specific, testable predictions about the conditions favoring pollinator movement into crops. In our simulations, the concentrator-exporter transition occurred at a lower flowering-intensity contrast than at pollen or nectar contrasts, which suggests that flowering intensity may provide an initial cue for bee movement, whereas nectar and pollen rewards refine or sustain bee responses once crops are perceived as attractive. Spillover thresholds differed among resource contrasts, whereas response steepness varied across bee-trait and community scenarios. Under the model's trait-sensitivity formulation, predicted spillover probability responded more strongly to flowering contrast for specialists than for generalists; colony size amplified this response, whereas bee richness dampened it. Together, these patterns show how flowering and resource contrasts interact with bee traits and community context to shape predicted spillover. Our results confirm that the concentrator and exporter hypotheses can be understood as context-dependent outcomes of the same ecological process rather than as mutually exclusive alternatives. Experimental tests of the predicted thresholds conducted in the field could reveal when and where floral plantings are most likely to promote bee spillover to crops, potentially supporting crop pollination.

A Computational Re-evaluation of Spatial Trials for Zoonotic Tuberculosis Control: Model Misspecification, Diagnostic Miss-classification, and the Illusion of Wildlife Culling Efficacy

1. Wildlife reservoir management frequently relies on the Randomised Badger Culling Trial's (RBCT) trade-off hypothesis, which posits that reductions in cattle herd infections are offset by a perturbation effect driven by disrupted host dispersal. This paper evaluates the computational and epidemiological robustness of this historical trial, which serves as the foundational empirical experiment guiding zoonotic tuberculosis (Mycobacterium bovis) control policies. 2. Using generalized linear mixed models with a generalized Poisson error distribution to explicitly address historical data overdispersion, this study contrasts traditional parametric inference against exact cluster-constrained permutation tests across distinct operational definitions of disease incidence. 3. Non-parametric diagnostics reveal that previously reported treatment and perturbation effects render as statistical artifacts under exact non-parametric permutation. Inside culling zones, parametric significance fails to withstand exact permutation verification due to extreme data leverage in localized cluster blocks. 4. Crucially, when diagnostic misclassification biases are eliminated by analysing total reactor datasets, all apparent culling effects disappear, and information criteria overwhelmingly favour nested null architectures. Unconfirmed reactors likely represent true biological infections missed by low-sensitivity post-mortem macro-necropsy, proving that host removal tracks observation noise rather than genuine zoonotic transmission pathways. 5. Finally, empirical scaling conducted in this study identifies a novel mathematical saturation effect, demonstrating that this sub-linear scaling is an operational artifact of unmodelled herd-level disease recurrence over time. 6. Policy implications. Because current zoonotic tuberculosis intervention frameworks are built upon a structurally misspecified statistical model, they have driven large-scale veterinary policies resulting in substantial, unevidenced ecological and economic interventions while failing to provide genuine public health, animal health, or disease control benefits.
