Ceanothus: Taxonomic patterns in life history responses to fire.

Ceanothus (Rhamnaceae) is a large genus of shrubs that dominate California chaparral and are resilient to fires. Persistence is ensured by resprouting and/or seedling recruitment from dormant seed banks. Some species do both and others, the obligate seeders, are entirely dependent on seedling recruitment. The distribution of these two modes within the genus is poorly documented. We used all available publications that document species responses to fire and filled most gaps in the literature based on extensive field studies of more than 60 recent wildfires in California. The genus is divided into two subgenera, Ceanothus and Cerastes. Ceanothus is widely considered to comprise mostly resprouting species and Cerastes to consist of only obligate seeders. The subgenus Ceanothus includes resprouting species throughout their range from the eastern United States and Midwest to western United States. Within the California Floristic Province (CFP), a few species are unique in producing massive lignotubers that develop from repeated fires; however, within the CFP, the majority of species in this subgenus do not resprout and are obligate seeders. Two have disjunct subspecies that are facultative seeders or obligate seeders. Previously, speciation in this genus was contended to have occurred in the late Miocene within the CFP. The syndrome of obligate seeding is most strongly represented in this region, and we hypothesize that evolution of this syndrome was a response to increased predictability of fire driven by the Mediterranean climate and the long interval between fires.

Exploring botanical diversity, ecological traits, and edaphic determinants in Kala Chitta National Park, Pakistan: Implications for conservation and management

Globally, environmental degradation has prompted several countries to strengthen their protected area networks to halt biodiversity loss. National parks incorporate into their design, are based on scientific evidence, and offer a complete management mechanism to enable successful conservation for the most ecologically critical and vulnerable ecosystem. However, managing these protected areas effectively requires a grasp of the complex dynamics of plant ecosystems and edaphic factors. Nevertheless, Pakistan's protected areas have seen the least investigation of these relationships. To fill this knowledge gap, this study investigates the vegetation dynamics and edaphic factors that influence plant distribution in Kala Chitta National Park of Pakistan. A comprehensive botanical survey documented 203 plant species across 60 study sites, revealing a diverse flora comprising species from 160 genera and 54 families. The most abundant families were Poaceae (34 species) and Fabaceae (21 species), Amaranthaceae (13 species) and Asteraceae (15 species). The majority of species were herbaceous (49.2%), followed by grasses (16.7%) and shrubs (15.2%). Climbers and ferns constituted 1.4% and 1.9% of the total, respectively, with co-dominant habits of tall reed and sedge accounting for 2.9% of the vegetation. Ecologically, Therophytes emerged as the most numerous life forms (42.8%), followed by hemicryptophytes (17.7%) and megaphanerophytes (8.3%). Analysis of leaf spectra revealed Nanophylls as the dominant type (36.9%), followed by Microphylls (33%). Phytogeographical distribution highlighted three major clusters, with Asia Tropical, Asia Temperate, and Europe accounting for 45% of species. Four distinct plant communities were identified using TWINSPAN analysis: Senegalia-Dichanthium-Justica (SDJ), Neltuma-Lantana-Cannabis (NLC), Prosopis-Saccharum-Desmostachya (PSD), and Dodonaea-Alhagi-Oxalis (DAO). Each community exhibited unique species compositions and ecological gradients influenced by edaphic factors. PCA revealed associations between specific edaphic variables and plant communities, with available phosphorus (AP) and potassium (AK) linked to the NLC community. At the same time, total nitrogen (TN) was predominantly associated with the DAO community. These findings highlight the importance of soil conservation and sustainable land management practices for preserving biodiversity and ecosystem integrity within Kala Chitta National Park. Future research should focus on long-term monitoring of vegetation dynamics and collaborative conservation initiatives involving local stakeholders to promote ecosystem resilience in the face of environmental change.

Genetic Identification of Endemic Fish Nomorhamphus liemi Vogt, 1978 from Sigi, Central Sulawesi, Indonesia

Sulawesi Island is geographically included in the Wallacea region, a transitional area between the Oriental and Australian zones, which makes Sulawesi’s fresh waters have a high level of fish species diversity. Some fish species found in Sulawesi freshwater are endemic. Research on Sulawesi endemic fishes in rivers is not as much as research on endemic fishes in lakes. Nomorhamphus liemi or locally known as angculung is one of Sulawesi’s endemic fishes. This species belongs to the sub-family Zenarchopterinae. The majority of species from the Zenarchopterinae sub-family are sexually dimorphic. This study aimed to molecularly identify angculung fish species using COI markers in the region. A total of nine angculung fish were collected and preserved using 96% alcohol. In the laboratory, tissue taken from the back of the dorsal fin was isolated and extracted, then amplified by PCR before sequencing. Sequencing results were validated on BLASTn, showing that nine samples belonged to Nomorhamphus liemi with 98-99% sequence similarity. The nucleotide base sequences were then analyzed using MEGA 7.0 software. The genetic distance of mackerel in these waters showed a close relationship. Phylogeny tree results showed population mixing so that mackerel in these waters can be managed in one management unit, especially in Sulawesi.

Out of and in East Asia: Phylogeny, biogeography and diversification of Thalictroideae (Ranunculaceae) in the Northern Hemisphere.

Understanding the biogeographical patterns and processes underlying the distribution of diversity within the Northern Hemisphere has fascinated botanists and biogeographers for over a century. However, as a well-known centre of species diversity in the Northern Hemisphere, whether East Asia acted as a source and/or a sink of plant diversity of the Northern Hemisphere remains unclear. Here, we used Thalictroideae, a subfamily widely distributed in the Northern Hemisphere with the majority of species in East Asia, to investigate the role of East Asia in shaping the biogeographical patterns of the Northern Hemisphere and to test whether East Asia acted as a museum or a cradle for herbaceous taxa. Based on six plastid and one nuclear DNA regions, we generated the most comprehensive phylogeny for Thalictroideae including 217 taxa (ca. 66% species) from all ten of the currently recognized genera. Within this phylogenetic framework, we then estimated divergence times, ancestral ranges, and diversification rates. The monophyletic Thalictroideae contains three major clades. All genera with more than one species are strongly supported as monophyletic except for Isopyrum, which is nested in Enemion. The most recent common ancestor of Thalictroideae occurred in East Asia in the late Eocene (ca. 36 Ma). From the Miocene onwards, at least 46 dispersal events were inferred to be responsible for the current distribution of this subfamily. East Asian Thalictroideae lineages experienced a rapid accumulation at ca. 10 Ma. The biogeographical patterns of Thalictroideae support the "out of and in East Asia" hypothesis, i.e., East Asia is both a source and a sink of biodiversity of the Northern Hemisphere. The global cooling after the middle Miocene Climatic Optimum, combined with the exposed land bridges due to sea-level decline, might have jointly caused the bidirectional plant exchanges between East Asia and other Northern Hemisphere regions. East Asia serves as evolutionary museums and cradles for the diversity of Thalictroideae and likely for other herbaceous lineages.

Utilizing Indigenous Knowledge Systems on Climate Change for Forestry Conservation in Kenya

A study on the toothing of edible caterpillar plants planted with FAS in Ibi- a village on the Batékéen Plateau the Democratic Republic of Congo. The main objective of this study was to identify and characterize the species of edible caterpillar plants planted in Ibi-village on the Batéké plateau. To do so, we used observation as a research method. In this study, 35 species of edible caterpillar host plants were identified, divided into 16 families and 7 orders. Regarding the ecological spectra of florule, Mesopotamians and sarcochores are predominant. On the phytogeographical level, the strong representativeness of the Guineo-Congolese element. Morphologically, the majority of species are trees. In this study, Pentaclethra eetveldeanaes the most dominant species. The most represented families are those of Fabaceae et Euphorbiaceae.

Relationships between environmental variables and fish functional groups in impounded reaches of the Upper Mississippi and Yangtze Rivers

Large rivers throughout the world have been transformed by anthropogenic stressors that are known to influence the structure and composition of fish assemblages. Management of large rivers requires balancing socio-economic and political considerations with biodiversity conservation efforts. By exchanging best management practices between rivers, management efforts can be improved. However, data limitations have largely prevented comparative analyses among fish assemblages in large rivers, potentially limiting the effectiveness of shared management strategies. To improve understanding of the similarities and differences between the Upper Mississippi and Yangtze Rivers, we (1) compared environmental variables and functional traits of fish assemblages between the two systems, (2) identified traits responsible for distinguishing functional groups from one another, and (3) investigated relationships between similar functional groups of fishes and environmental variables to establish expectations for how fish assemblages in large rivers might respond to anthropogenic stressors. Regional species pools in the Upper Mississippi and Upper Yangtze Rivers were characterized by a similar composition of functional traits; the majority of species were omnivorous, had affinities for gravel or sand substrates, and produced sinking eggs. Few species were pelagic, planktivorous, or herbivorous. Functional groups in both rivers were primarily distinguished according to species' trophic habits and substrate preferences, with secondary contributions from species’ water column positions and life history characteristics. Pelagic planktivores and small-bodied guarders with an affinity for structural habitat complexity tended to increase downriver in both systems, in direct association with total phosphorus concentrations, agricultural land use, and temperature. In contrast, proportions of lithophilic species with affinities for gravel or cobble substrates were highest in segments located furthest upriver. By highlighting the sensitivity of different groups of fishes to anthropogenic stressors, we provide insights into the functional ecology of fishes inhabiting the Mississippi and Yangtze Rivers.

A new metric for conducting 5‐year reviews to evaluate recovery progress under the Endangered Species Act

AbstractThe Endangered Species Act (ESA) provides legal protection to imperiled populations and their associated habitats. As a part of this process, listed species must undergo a general status review (also called 5‐Year Review) to assess the progress toward recovery every 5 years. However, almost all 5‐year reviews result in a status of “no change,” prompting scientists to question if the review process is robust enough to detect changes in recovery. The U.S. Fish and Wildlife Service (USFWS) was therefore interested in developing a standardized metric for monitoring more nuanced recovery progress as part of the status review. In collaboration with the USFWS, over 75 biologists from five different organizations developed and tested a set of novel metrics to summarize recovery progress of listed species by considering current and future conditions, threats, and conservation measures. We found that, although the majority of species had reviews with a recommendation of no change, scorers were able to use the metrics to interpret more nuanced changes in the 3Rs (resiliency, redundancy, and representation), threats, and conservation measures than in the status review. Our results suggest that these metrics could illuminate more nuanced areas of recovery and decline in species' conditions, but consistency among scorers and status reports should be a focus of future development. Our approach offers a rigorous set of metrics to systematically track the recovery progress of all ESA species.

A Systematic Analysis of the Mediterranean Sea (IHO Sea Area) in the WRiMS Database

The invasion of non-native species (NNS) is one of the greatest threats to biodiversity loss and represents a major problem in the Mediterranean Sea. Although many recent EU policies and directives address this problem and numerous scientific papers have been published, the available data remains scattered and incomplete. In 2021, the World Register of Introduced Marine Species (WRiMS), a newly established database, was launched but has not yet undergone systematic analysis. This study performed a thorough examination of the NNS documented in the WRiMS database within the Mediterranean Sea (International Hydrographic Organization Sea Area). Our findings revealed that the majority of species in the WRiMS database for the Mediterranean are classified as “unspecified” or “uncertain”, with only 79 species labeled as “invasive” and 13 as “of concern”. The number of recorded animal species exceeds that of plants, and most species belong to the phyla Chordata and Mollusca. Callinectes sapidus and Fistularia commersonii were the most frequently recorded species in the WRiMS for the Mediterranean. Although there exists some data on the impact of NNS and the vectors of their introduction, the information remains incomplete and requires further scientific research. The synthesized and summarized data in the supplement can be valuable input for a range of management decisions and for guiding further scientific research concerning NNS invasions in the Mediterranean Sea.

Birds have always fascinated mankind with their naturally attractive plumage, harmonious songs and creative behavior. Avifaunal Diversity is one of the most important ecological indicators, displays the environmental quality of an area, its pollution level, safety and accessibility of food and habitat. Cantonment area is one of the distinctive locations represents a sub-urban area of Lucknow. Cantonment area is an abundant green area around 23.43 square kilometer, preferred by number of bird species at its different types of habitat like shaded trees, bushes, grasses, grounds some parks and buildings etc. They provide food and shelter for the urban terrestrial bird’s community. The study was performed in Cantonment area for six months from February, 2022 to July, 2022. Bird surveys were carried out using the Line transect method across four different transects at this area. As a result of six months observation, 55 bird species were recorded belonging to 15 orders and 29 families. Majority of species were observed in the order Passeriformes and family Muscicapidae. Data analysis showed that 29 avian species were Common, 12 were Fairly Common, 6 were Uncommon and 8 were Rare, whereas 52 avian species were residents and 3 avian species were migrants.

Sem Studies on Spermoderm of some Species of <i>Medicago</i> (Papilionoideae-Trifolieae)

Seeds of 9 species of Medicago have been investigated under light and scanning electron microscope to find out the systematic significance of spermoderm pattern. Under light microscope, the surface is smooth in all the species except M. monantha and M. orbicularis where it is tuberculate. Under scanning electron microscope, majority of species viz., M. laciniata , M. lupulina, M. minima, M. orbicularis. M. polymorpha var. vulgaris and M. × varia show tuberculate (papillose) pattern while M. edgeworthii, M. monantha and M. sativa show false reticulate, reticulate and rugulate patterns respectively. The nature of tubercules differs from species to species and thus spermoderm pattern can be used in the identification of plants at specific level.

A new species of Mexicope Hooker, 1985 (Crustacea, Isopoda) - the first record of Acanthaspidiidae Menzies, 1962 from the Mediterranean Sea.

The marine isopod family Acanthaspidiidae Menzies, 1962 (Asellota, Janiroidea) has global distribution from shelf to hadal depth. The majority of species has been recorded from relatively deep waters and the Southern Hemisphere. To date, 36 species have been described in the family belonging to three genera: Ianthopsis Beddard, 1886; Iolanthe Beddard, 1886; and Mexicope Hooker, 1985. Here, a new species of Mexicope is described from Maltese waters, adding a fourth species to the genus. It is the first member of the family reported from the Mediterranean Sea. The new species can be recognised by the unique combination of the following characters: cephalothorax with pre-ocular spine large and pointed anterolaterally, rostral projection blunt, eyes reduced; pereonal sternites each with one ventral spine; pereonite two lateral margins with single projection; pleotelson posterior apex long, projecting to approximately half of the length of the uropod protopod; pleopods I distolateral lobes projecting beyond distomedial lobes, apices curved and pointed laterally; uropod exopod length approximately 0.5 endopod length. An identification key to the species of Mexicope is presented and the generic diagnoses of Ianthopsis and Mexicope are compared, discussed and revised.

Phylogenetics of the rust fungi (Pucciniales) of South Africa, with notes on their life histories and possible origins

ABSTRACT South Africa has an indigenous rust (Pucciniales) funga of approximately 460 species. This funga was sampled with species from as many genera as possible. The nuclear ribosomal large subunit (28S) region was amplified from samples representing 110 indigenous species, as well as the small subunit (18S) region and the cytochrome c oxidase subunit 3 (CO3) in some cases, and these were used in phylogenetic analyses. One new species is described, 12 new combinations made, six names reinstated, and two life history connections made. The life histories of this funga were summarized; it is dominated by species with contracted life histories. The majority of species are autoecious, with a small proportion being heteroecious. Of the autoecious species, many will likely be homothallic with no spermagonia. A shortened life history with homothallism allows for a single basidiospore infection to initiate a local population buildup under the prevailing unpredictable climatic conditions. Suggestions are made as to the possible origin of this funga based on the development of the modern South African flora. It is postulated that the rusts of South Africa are of relatively recent origin, consisting of three groups. Firstly, there is an African tropical element with members of the Mikronegerineae (Hemileia), the Sphaerophragmiaceae (Puccorchidium, Sphaerophragmium), and certain Uredinineae (Stomatisora). Their immediate ancestors likely occurred in the tropical forests of Africa during the Paleogene. Secondly, there is a pantropical element including the Raveneliaceae (e.g., Diorchidium, Maravalia, Ravenelia sensu lato, Uropyxis). This likely diversified during the Neogene, when the mimosoids became the dominant trees of the developing savannas. Thirdly, the Pucciniaceae invaded Africa as this continent pushed northward closing the Tethys Sea. They diversified with the development of the savannas as these become the dominant habitat in most of Africa, and are by far the largest component of the South African rust funga.

Survey of plant species used in the treatment of common ailments in Hawul Local Government Area, Borno State, Nigeria

To record the locals' knowledge of some of the medicinal plant species in the area, a survey of plant species used for the treatment of common ailments was carried out in Hawul Local Government Area Borno State. A semi-structured questionnaire was used to collect the data. Numerous quantitative indices, including Informant Consensus Factor (ICF), Use Value (UV), Fidelity Level (FL), Shannon Weiner Index, Simpson Index, Relative Frequency of Citation (RFC), and Family Importance Value (FIV), were used to quantify the advantages, significance, and coverage of ethnomedicine. The Jaccard Index (JI) was used to assess the degree of homogeneity between the current study and earlier research as well as within indigenous tribes. A total of fifty-five (55) medicinal plants species, which were distributed under twenty-nine (29) families were documented from one hundred (100) informants. The majority of species that have been identified are tree species, and the most common plant portion used to make ethnomedicines is leaf material. The Fabaceae were the predominate families among the species that had been documented (11 species) Accacia nilotica, Piliostigma thonningii, Detarium microcarpum, Faidherbia albida, Sennia siamea, Prosopis Africana, Parkia baglobosa, Tamarindus indica, Pterocarpus erinaceus, Senna occidentalist, Senna obtusifolia, while the least represented was (1 species) Apocynacea. For digestive system problems, the highest ICF score was 0.77. According to the data gathered from the questionnaires, pile, yellow fever, malaria, typhoid, stomach ache, and ulcer were the most prevalent diseases, in that order. Based on UVs, the two most commonly cited ethnomedicinal plant species in the study area were Khaya senegalensis (0.40), Piliostigma thonningii (0.35) while the least was (0.01) Guinea senegalensis. The most common method of preparation was by decoction and the major route of administration was oral while least cited was sit bath. Phytochemical profiles demonstrated that flavonoids, alkaloids phenols, saponins and tannins were the major phytochemical component in Khaya. senegalensis and Piliostigma. thonningii leaves. This further justifies the frequent application of these plants in folklore medicine by the traditional herbal practitioners to treat different forms of illnesses. It is stated that due to their physiologically active ingredients and accessibility, herbal medicine will continue to play a significant role in the community's health care delivery system.

Rethinking pathways to the dioecy-polyploidy association: Genera with many dioecious species have fewer polyploids.

Numerous studies have found a positive association between dioecy and polyploidy; however, this association presents a theoretical conflict: While polyploids are predicted to benefit from self-reproduction for successful establishment, dioecious species cannot self-reproduce. We propose a theoretical framework to resolve this apparent conflict. We hypothesize that the inability of dioecious species to self-reproduce hinders their establishment as polyploids. We therefore expect that genera with many dioecious species have fewer polyploids, leading to a negative association between polyploidy and dioecy across genera. We used three publicly available databases to determine ploidy and sexual systems for 131 genera and 546 species. We quantified (1) the relationship between the frequency of polyploid species and the frequency of dioecious species across genera, and (2) the proportion of polyploids with hermaphroditism and dioecy across species, adjusting for phylogenetic history. Across genera, we found a negative relationship between the proportion of polyploids and the proportion of dioecious species, a consistent trend across clades. Across all species, we found that sexual system (dioecious or not) was not associated with polyploidy. Polyploids are rare in genera in which the majority of species are dioecious, consistent with the theory that self-reproduction favors polyploid establishment. The low frequency of polyploidy among dioecious species indicates the association is not as widespread as previously suggested. Our findings are consistent with previous studies identifying a positive relationship between the two traits, but only if polyploidy promotes a transition to dioecy, and not the reverse.

Another Brick in the Wall of Tear Film Insights Added Through the Total Synthesis and Biophysical Profiling of anteiso-Branched Wax and Cholesteryl Esters.

The tear film lipid layer (TFLL) plays a vital part in maintenance of ocular health and represents a unique biological barrier comprising unusual and specialized lipid classes and species. The wax and cholesteryl esters (WEs and CEs) constitute roughly 80-90% of the TFLL. The majority of species in these lipid classes are branched and it is therefore surprising that the synthesis and properties of the second largest category of species, i.e., the anteiso-branched species, remain poorly characterized. In this study, we have developed a total synthesis route and completed a detailed NMR spectroscopic characterization of two common anteiso-branched species, namely: (22S)-22-methyltetracosanyl oleate and cholesteryl (22'S)-22'-methyltetracosanoate. In addition, we have studied their structural properties in the bulk state by wide-angle and small-angle X-ray scattering and their behavior at the aqueous interface using Langmuir monolayer techniques. A comparison to the properties displayed by iso-branched and straight-chain analogues indicate that branching patterns lead to distinct properties in the CE and WE lipid classes. Overall, this study complements the previous work in the field and adds another important brick in the tear film insights wall.

Two new species of Erythroneurini (Hemiptera, Cicadellidae, Typhlocybinae) from southern China based on morphology and complete mitogenomes.

Erythroneurine leafhoppers (Hemiptera, Cicadellidae, Typhlocybinae, Erythroneurini) are utilized to resolve the relationship between the four erythroneurine leafhopper (Hemiptera, Cicadellidae, Typhlocybinae, Erythroneurini): Arboridia (Arboridia) rongchangensis sp. nov., Thaia (Thaia) jiulongensis sp. nov., Mitjaevia bifurcata Luo, Song & Song, 2021 and Mitjaevia diana Luo, Song & Song, 2021, the two new species are described and illustrated. The mitochondrial gene sequences of these four species were determined to update the mitochondrial genome database of Erythroneurini. The mitochondrial genomes of four species shared high parallelism in nucleotide composition, base composition and gene order, comprising 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs) and an AT control region, which was consistent with majority of species in Cicadellidae; all genes revealed common trait of a positive AT skew and negative GC skew. The mitogenomes of four species were ultra-conservative in structure, and which isanalogous to that of others in size and A + T content. Phylogenetic trees based on the mitogenome data of these species and another 24 species were built employing the maximum likelihood and Bayesian inference methods. The results indicated that the four species belong to the tribe Erythroneurini, M. diana is the sister-group relationship of M. protuberanta + M. bifurcata. The two species Arboridia (Arboridia) rongchangensis sp. nov. and Thaia (Thaia) jiulongensis sp. nov. also have a relatively close genetic relationship with the genus Mitjaevia.

Homogeneity Gut microbiome Characteristics in Autoimmune Epithelitis: Primary Biliary Cholangitis and Primary Sjögren’s Syndrome.

Background : Accumulating studies had revealed that dysbiosis of the gut microbiome was involved in the occurrence and development of Primary biliary cholangitis (PBC) and Primary Sjögren’s syndrome (pSS). Aims : To examine the similarities and differences in gut microbiome as well as the relationship with pathogenesis in PBC and pSS. Methods : High throughput sequencing was conducted to analyze the 16S rDNA V3-V4 region of fecal microbial samples from 109 subjects including PBC (n=38), pSS (n=41) and healthy controls (HC, n=30) from the Affiliated Hospital of Qingdao University. The composition, diversity and markers of gut microbiome were compared between PBC, pSS and HC. Inter-group comparisons were conducted using analysis

Investigation of potential rubber-degrading bacteria and genes involved.

COVID-19 pandemic has generated high demand for natural rubber gloves (NR) leading to crucial issues of rubber waste and waste management such as burning, dumping, stockpiling, discarding waste in landfills. Hence, rubber biodegradation by microorganisms is an alternative solution to the problem. The biodegradation method is environmentally friendly but normally extremely slow. Numerous microorganisms can degrade NR as a source of carbon and energy. In this study, Rhodococcus pyridinivorans KU1 was isolated from the consortium CK from previous study. The 40% rubber weight loss was detected after incubated for 2months. The bacterial colonization and cavities on the surface of rubber were identified using a scanning electron microscope (SEM). The result demonstrated the critical degradation of the rubber surface, indicating that bacteria can degrade rubber and use it as their sole carbon source. The result of whole-genome sequencing (WGS) revealed a gene that is 99.9% identical to lcp which is responsible for poly (cis-1,4-isoprene) degradation. The results from Meta16S rRNA sequencing showed that the microbial communities were slightly shifted during the 2-month degradation, depending on the presence of monomers or oligomers appeared during the degradation process. The majority of species were soil bacteria such as phylum Proteobacteria, Actinobacteria, and Firmicutes. Members of Pseudoxanthomonas seemed to be the dominant degraders throughout the degradation.

A life-and-death struggle: interaction of insects with entomopathogenic fungi across various infection stages.

Insects constitute approximately 75% of the world's recognized fauna, with the majority of species considered as pests. Entomopathogenic fungi (EPF) are parasitic microorganisms capable of efficiently infecting insects, rendering them potent biopesticides. In response to infections, insects have evolved diverse defense mechanisms, prompting EPF to develop a variety of strategies to overcome or circumvent host defenses. While the interaction mechanisms between EPF and insects is well established, recent findings underscore that their interplay is more intricate than previously thought, especially evident across different stages of EPF infection. This review primarily focuses on the interplay between EPF and the insect defense strategies, centered around three infection stages: (1) Early infection stage: involving the pre-contact detection and avoidance behavior of EPF in insects, along with the induction of behavioral responses upon contact with the host cuticle; (2) Penetration and intra-hemolymph growth stage: involving the initiation of intricate cellular and humoral immune functions in insects, while symbiotic microbes can further contribute to host resistance; (3) Host insect's death stage: involving the ultimate confrontation between pathogens and insects. Infected insects strive to separate themselves from the healthy population, while pathogens rely on the infected insects to spread to new hosts. Also, we discuss a novel pest management strategy underlying the cooperation between EPF infection and disturbing the insect immune system. By enhancing our understanding of the intricate interplay between EPF and the insect, this review provides novel perspectives for EPF-mediated pest management and developing effective fungal insecticides.

Review of Herbal Medicinal Plants Used in the Management of Cancers in the East Africa Region from 2019 to 2023.

In the East African region, herbal plants are essential in the treatment and control of cancer. Given the diverse ecological and cultural makeup of the regional states, it is likely that different ethnic groups will use the same or different plants for the same or different diseases. However, since 2019, this has not been compiled into a single study. The study aimed to compile and record the medicinal plants utilized in East Africa from April 2019 to June 2023 to treat various cancer types. The study examined 13 original studies that included ethnobotanical research conducted in East Africa. They were retrieved from several internet databases, including Google Scholar, Scopus, PubMed/Medline, Science Direct, and Research for Life. The study retrieved databases on plant families and species, plant parts used, preparation methods and routes of administration, and the country where the ethnobotanical field surveys were conducted. Graphs were produced using the GraphPad Prism 8.125 program (GraphPad Software, Inc., San Diego, CA). Tables and figures were used to present the data, which had been condensed into percentages and frequencies. A total of 105 different plant species from 45 different plant families were identified, including Asteraceae (14), Euphorbiaceae (12), Musaceae (8), and Apocynaceae (7). Uganda registered the highest proportion (46% of the medicinal plants used). The most commonly mentioned medicinal plant species in cancer management was Prunus africana. Herbs (32%), trees and shrubs (28%), and leaves (45%) constituted the majority of herbal remedies. Most herbal remedies were prepared by boiling (decoction) and taken orally (57%). East Africa is home to a wide variety of medicinal plant species that local populations and herbalists, or TMP, frequently use in the treatment of various types of cancer. The most frequently used families are Asteraceae and Euphorbiaceae, with the majority of species being found in Uganda. The most frequently utilized plant species is Prunus africana. Studies on the effectiveness of Prunus africana against other malignancies besides prostate cancer are required.
