Anthropogenic disturbance of natural environments has negative impacts on biodiversity. Amphibians are especially sensitive to deforestation, and there is a high rate this phenomenon in the Democratic Republic Congo. We studied effects modification forest ecosystems diversity amphibians Yoko Forest Reserve. During twenty-four field sampling campaigns organized over period twelve months, were collected from nocturnal surveys supported by three techniques: visual spotting using headlamp, systematic searching habitats acoustic hearing vocalizations. Twelve sites chosen, explored at each site. Of these habitats, one undisturbed habitat (primary forest), two disturbed (fallow field). Amphibian abundance, species richness, diversity, evenness density compared between types habitat. A total 4443 10 families, 17 genera 33 recorded throughout study area. Abundance, richness relative significantly higher non-disturbed than habitats. On other hand, primary less diverse fallow, but not significantly. It is, however, more field. The also characterized lower with which it shares low similarities. Amnirana albolabris, Phrynobatrachus auritus, Leptopelis notatus, millsoni, Xenopus pygmaeus, Hyperolius platyceps, calcaratus, christyi, ocellatus, Arthroleptis tuberosus, Ptychadena perreti, Amietia nutti, variabilis, Cardioglossa leucomystax, perpalmatus Chiromantis rufescens recognized, order importance, as indicators according results study. All differences statuses (undisturbed disturbed) confirm alteration amphibians.

Predator-prey interactions are among the most common and crucial ecological phenomena in nature. Over course of long-term evolution, prey populations have developed various anti-predation strategies to cope with threat predators, population dispersal being one strategies. In traditional models, is typically constrained by direct predation. However, an increasing body empirical evidence suggests that fear effect from predator significantly alters physiological behavior prey, leading a decrease reproduction rate increase mortality rate. this paper, we investigate predator-prey system incorporating asymmetric effect, which influences birth death rates species. We rigorously establish existence local stability equilibrium points, derive sufficient conditions for global stability, prove occurrence transcritical bifurcation at boundary equilibrium. Our analysis reveals optimal maximizes density; beyond threshold, increased drives both extinction. Furthermore, its maximum cost exhibit significant negative impacts on abundance, though they do not alter or existence. These findings provide critical insights designing habitat corridors endangered species conservation underscore pivotal role shaping dynamics.

Abstract Age and growth‐related data are basic biological parameters, essential in population ecology, evolution, conservation biology. There is a growing body of published information on reptile demography derived from sclerochronology, technique based counting the growth layers deposited bones (skeletochronology) other hard structures. Since not always easily available, we compiled existing data, described current status knowledge, synthetized conclusions disparate studies, identified patterns research gaps, prioritizing needs for future research. Our database includes results 468 studies covering 236 species 41 families. These represent less than 2% total number known extant species. Turtles crocodiles proportionally better studied, while snakes least examined group. The distribution does reflect needs; found an important geographic bias, with overrepresentation Northern temperate Only 23% checked assumption periodicity marks deposition, method was to be reliable or adequate 79% cases. Overall, obtained through sclerochronology can considered robust, especially if validation methods employed, since general goal characterize trends, dynamics, rather determining exact age any specimen particular.

Mountain ecosystems offer valuable opportunities to study species distribution and diversity along altitudinal gradients, particularly for amphibians. This research examined amphibian distribution, diversity, conservation across an elevational gradient in the Tangjiahe National Nature Reserve, part of Hengduan Mountains southwestern China. A total 25 species, encompassing 8 families 2 orders, were documented, including three newly recorded species: Fejervarya kawamurai, Polypedates braueri, Boulenophrys minor. Among these, eight designated as “threatened” under IUCN criteria are listed on China’s Biodiversity Red List. Caijiaba exhibited highest whereas Shuichiping had lowest. Fourteen found terrestrial-farmland aquatic-lotic habitats, which supported greatest richness. The pattern showed peaks richness at 900–1100 m 1900–2100 elevation bands, with higher elevations displaying reduced These findings highlighted spatial characteristics ranges Reserve provide insights formulating policies adaptive habitat management strategies.

Abstract This study explores the vegetation composition along various tram line sections in Bydgoszcz, Poland, with a focus on understanding impact of usage, maintenance, and historical development urban dynamics. addresses this knowledge gap by investigating how these factors influence plant species composition, leading to variations prevalence native non‐native species. The aim is contribute ecological inform management strategies. investigation centers five sites representing different usage maintenance scenarios: Unused line, New Loop rec, old, Old line. Through phytocoenological relevés conducted 2020 2021, we measured taxa coverage. Detrended Correspondence Analysis (DCA) Canonical (CCA) revealed relationships between sites. results indicated presence 107 taxa, graphical representations highlighting prevalent each section. Older showed higher representation species, whereas new exhibited dominance. Moisture‐indicative values suggest an affinity for soils average moisture content. CCA provides insights into site variants offers valuable implications conservation novelty lies its holistic approach multiple interact shape vegetation. By illuminating dynamics informing decision‐making processes, contributes planning, ecology, biodiversity conservation. Additionally, fills providing unique lines environments.

Research efforts to protect Philippine biodiversity have increased significantly. However, there is an imbalance in the distribution of published studies, with specific territories receiving more attention than others. Mindanao, a southern group islands, known for its high levels endemism amphibians and reptiles. Despite this, research on these groups remains scattered. To address this gap, we conducted literature review focusing reptiles Mindanao faunal region. We found increasing effort towards herpetofauna over two decades, yet clear bias compared Furthermore, that significantly higher species threat index all other vertebrate groups, regardless conservation status. Yet, threatened those facing greater threats are poorly studied general. Understanding factors driving biases Philippines essential allow us redirect most needed areas, particularly understudied neglected taxa Mindanao.
