Genomic instability is a condition that may be associated with carcinogenesis and/or physiological disorders when genetic lesions are not repaired. Besides, wild, captive, and domesticated vertebrates exposed to xenobiotics, leading health due cytogenotoxicity. This chapter provides an overview of tests assess cytogenotoxicity based on micronuclei (MNi) formation. Bone marrow test (BmMNt), peripheral blood erythrocyte (PBMNt), lymphocyte cytokinesis blocking assay (CBMN) discussed. The most illustrative studies these techniques applied in different veterinary interest described. values spontaneous basal experimental, farm animals (rodents, hamsters, pigs, goats, cattle, horses, fish) summarized. In addition, flow cytometry technique presented reduce the time taken record MNi other cellular abnormalities. Flow helpful analyze some indicators genomic instability, such as cell death processes stages (necrosis, apoptosis) efficiently evaluate biomarkers genotoxicity like BmMNt, PBMNt, CBMN. intention provide professionals interpret anticipate therapeutic management at risk or degenerative diseases.

Insectivorous bats provide ecosystem services in agricultural and urban landscapes by consuming arthropods that are considered pests. Bat species inhabiting cities expected to consume insects associated with areas, such as mosquitoes, flying termites, moths, beetles. We captured insectivorous the Federal District of Brazil used fecal DNA metabarcoding investigate arthropod consumed five bat living colonies city buildings, ascertained whether their predation was related services.

Conventional agriculture occupies a substantial portion of Earth's terrestrial surface and adversely affects biodiversity through pesticide spread, mechanisation, loss spatial temporal heterogeneity farmed landscapes. Consequently, conventional has become primary target many restoration projects operating at various scales, from habitat to landscape. While these efforts aim increase farmland promote the delivery associated ecosystem services, unintended consequences may arise when important threats are not mitigated. For instance, animals be led make maladaptive choices, lured attractive sites with poor quality (ecological traps), resulting in adverse effects on individual fitness demography. We focus our review European as case study because its extensive presence continent particularly articulated legal framework regulating within Union. Europe's policy is dual-faced: one promotes development regardless management practices, while other advocates for protection measures that sometimes lack strong supporting evidence or overlook critical aspects. Insectivorous bats contribute significantly service insectivory agricultural landscapes, consuming large numbers pest arthropods. However, restoring habitats farmland, potential outcomes must considered, if actions accompanied by mitigation key threats.

Abstract Trifloxystrobin (TFS) is a strobilurin-type fungicide that should be investigated due to its risks non-targeted organisms. The goal of this study was assess the susceptibility Allium cepa L. TFS in multi-pronged approach. For 72 h, 0.2 g/L, 0.4 g/L and 0.8 doses were administered A. bulbs control group treated with tap water. toxic effects tested, considering physiological, cytogenetic, biochemical anatomical analyses. delayed growth by reducing rooting ratio, root elongation weight increase. Following treatments, mitotic index (MI) scores decreased, while formation micronucleus (MN) chromosomal aberrations (CAs) ascended. CAs types induced listed according their frequency as fragment, vagrant chromosome, sticky uneven distribution chromatin, bridge, nucleus vacuoles, reverse polarization irregular mitosis. provoked an increment superoxide dismutase (SOD) catalase (CAT) enzyme activities well accumulation malondialdehyde (MDA). Meristematic cells roots had various damages, including damaged epidermis, flattened cell nucleus, cortex thickness wall. All damages arising from treatments exhibited dose-dependency. findings present revealed serious toxicity plant. It not neglected evaluate potential hazards different tests.

Abstract Worldwide, artificial bat roosts (e.g., boxes, bark mimics, condos) are routinely deployed for conservation, mitigation, and community engagement. However, scant attention has been paid to developing best practices the use of as conservation tools. Although bats readily occupy roosts, occupancy abundance data misleading indicators habitat quality. Lacking information on behavior, health, fitness in their efficacy cannot be adequately validated. We considered proximal ultimate factors, such evolutionarily reliable cues, that may prompt preferentially show fidelity suboptimal even when high‐quality alternatives available. Possible negative health consequences roost inhabitants include exposure unstable extreme microclimates poorly designed vulnerability larger numbers ectoparasites longer lasting house colonies than natural roosts. Bats using have lower survival rates if predators easy access placed conspicuous locations. lured into occupying low‐quality habitats attractive polluted urban agricultural landscapes. To advance science behind we present testable research hypotheses suggestions improve quality decrease risks occupants. Because continued loss increase reliance alternatives, it is imperative this practice improved.
