Over the past 15 years, disease ecology has become a discipline in its own right. It is fundamentally based on training and evolution, with solid theoretical foundations skills computational biology statistics, it differs from medical approach to interpretation of disease. concerned how species interactions, including host–pathogen relationships environmental conditions (e.g. temperature rainfall), affect patterns processes presence spread, pathogens impact host individuals, populations, communities, ultimately ecosystem function (Ostfeld et al. 2008). Initially rooted parasite ecology, particularly among researchers working transmission cycles host–disease population dynamics, mainly focuses parasitic infectious diseases but not exclusive them 2018). A booming subfield currently concerns research linking different areas such as transmission, agriculture development, development aid policies, notably world's poorest countries (Ngonghala 2014). Unlike ecologists, ecologists focus understanding causes consequences maintenance animal species, humans, plants, communities species. much more widespread studies wild also their contacts domestic e.g. livestock, interactions human less so plant which some respects are plant-pathology molecular-orientated (Guégan 2023a).

Anthropogenic Pressures on Gorillas: A Case of Grauer’s Gorillas in Maiko National Park, the Democratic Republic of Congo

Diversity, Journal Year: 2024, Volume and Issue: 16(4), P. 236 - 236

Published: April 16, 2024

Anthropogenic activities put biodiversity under pressure, adversely affecting the forest ecosystem and wildlife habitats. Habitat disturbance modification are among main threats to animal populations in tropical forests. In Democratic Republic of Congo (DRC), Grauer’s gorillas (Gorilla beringei graueri) continuously threatened through encroachment for agricultural expansion, human settlements, new refugee camps, illegal logging, mining across country. Moreover, poaching bushmeat trafficking threaten gorillas’ existence. These drivers increase proximity humans risk disease transmission. The emerging existing zoonotic diseases, including Ebola, impacting lives. All these pressures combined disrupting natural behavior patterns leading decline population. Therefore, this review scrutinizes findings on anthropogenic habitats survival gorillas. Also, it is important engage with people shared conservation role ecotourism support habitats, particularly Maiko National Park DRC.

Published: March 31, 2024

Hama dan penyakit tanaman jagung berpotensi menimbulkan gagal panen. Kurangnya informasi pengetahuan mengenai serangan hama serta terbatasnya penyuluh lapangan menyebabkan kesalahan dalam diagnosa jenis jagung. Hal ini berakibat pada pengelolaan yang kurang tepat sehingga produksi menurun. Oleh karena itu, petani membutuhkan sebuah alat bantu untuk mendeteksi melalui gejala fisik terlihat di lapangan. Penelitian bertujuan menghasilkan Sistem Informasi Pertanian (SIP) yaitu sistem pakar berbasis android Metode digunakan adalah perangkat lunak dengan prototyping mendapatkan gambaran aplikasi akan dibangun rancangan prototype kemudian dievaluasi oleh user. Tahapan penelitian meliputi ; pengumpulan kebutuhan, membangun prototype, evaluasi protoype, pengkodean system, menguji penggunaan system.

Spatiotemporal dynamics of land use and land cover change around Volcanoes National Park and their implications for biodiversity conservation

Biodiversity, Journal Year: 2024, Volume and Issue: 25(3), P. 263 - 281

Published: July 2, 2024

This study comprehensively analyses spatiotemporal land use/land cover (LULC) dynamics within a 10-km buffer zone surrounding Volcanoes National Park (VNP), Rwanda, from 2000 to 2019, integrating biophysical and socio-economic drivers. It aims quantify LULC change extent, rate, type around VNP inside the park; identify socio-economic, demographic, policy drivers of change; evaluate impact changes on VNP's biodiversity via habitat fragmentation, connectivity, species diversity. Employing remote sensing, spatial modelling, field data, we reveal profound transformations park's periphery. Forests woodlots have significantly declined, replaced by agriculture, grasslands, built-up areas, particularly in 5.1–10 km belt (92.29% forest loss). While reforestation efforts exist, they are outpaced deforestation, creating stark deforestation-to-reforestation ratio 12:1 5.1 10 6:1 0–5 belt. alarming trend threatens as resource dependent communities continue extract firewood, construction materials, beanpoles park. To mitigate these impacts, propose integrated strategies encompassing strengthened law enforcement, sustainable management practices, community-based conservation initiatives, alternative livelihood development.

Abstract Aquilaria (Thymelaeaceae), a tropical and subtropical plant, is one of the main genera that can produce agarwood. sinensis yunnanensis are native Chinese tree species, A. China's agarwood source. Agarwood nontimber forest product with high economic medicinal value. First‐grade sold as much $100 000 per kilogram. There has been little research on saprobic fungi associated , only 11 records having reported. In present study, 10 terrestrial were collected in China. Based morphological phylogenetic studies, these collections introduced herein new genus ( Aquilariomyces ), nine species – aquilariae Corynespora Melomastia maomingensis Nigrograna Parathyridariella Peroneutypa Phaeoseptum Pseudothyridariella Triangularia known Camarographium clematidis ).
