* Animals often use colours to hide from predators (crypsis) or advertise defences (aposematism), but there is little evidence for colour-based defence in plants. Here, we test whether ontogenetic changes leaf colour of lancewood (Pseudopanax crassifolius) may have been part a defensive strategy against flightless browsing birds called moa, which were once the only large herbivores New Zealand. We tested this hypothesis by conducting spectrographic measurements on different-sized plants...
Controlling pest birds is a complex problem, especially for large areas, compared to individual homes. This study presents new perspective on plaguing semiconductor factory. We evaluated the efficacy of nine bird deterrent methods: alarm and distress calls broadcasted from portable speaker, sound frequencies ranged (i) 24.5 kHz–45.5 kHz; (ii) 13.5 kHz together with flashing lights emitted sonic device, methyl anthranilate (MA), moving static predator models, reflective compact discs, high...
The color of many animals matches that their preferred habitats, making them difficult for predators to locate. However, quantitative examples crypsis in plants are comparatively rare. We conducted morphometric and spectrographic analyses a heteroblastic tree species is endemic New Zealand (Elaeocarpus hookerianus Raoul) test whether it cryptic appearance from the perspective birds, who were once dominant browsers Zealand. leaves smaller, juvenile highly variable size shape mottled brown...
Discarded cigarette butts (DCB) waste occurs worldwide, pollutes landscapes, is unsightly, and results in added debris removal costs. There is, therefore, a great deal of current interest making use DCBs beneficial ways. Despite evidence that are harmful to water fleas (Daphnia magna), which breed aquatic environments as do mosquito larvae, their impact on dengue vectors unknown. We examined whether Aedes albopictus alters its ovipositional responses, larval eclosion, development response...
Viable biocontrol agents for mosquito control are quite rare, therefore improving the efficacy of existing biological is an important study. We need to have a better understanding predation-risk behavioral responses toward prey. This research examined prey choices by Toxorhynchites splendens monitoring Aedes aegypti, albopictus, and Anopheles sinensis larvae when exposed predator. The results show that Tx. prefers consume Ae. aegypti larvae. exhibited different was present which suggest...
Calamus castaneus is a common rattan palm species in the tropical forests of Peninsular Malaysia and noticeable by yellow-based spines that cover stems. This study aimed to determine prevalence fungal endophytes within C. whether they inhibit growth pathogens. Twenty-one genera with 40 were isolated identified from spines. Based on molecular identification, most isolates recovered Colletotrichum (n = 19) Diaporthe spp. 18), followed Phyllosticta spp., Xylaria sp., Trichoderma...
Mating is a physiological process of crucial importance underlying the size and maintenance mosquito populations. In sterile incompatible insect technologies (SIT IIT), mating essential for mass production, persistence, success released individuals, central parameter judging effectiveness SIT/IIT programs. Some mosquitoes have an enormous reproductive potential both themselves pathogens may contribute to persistence infection in nature. As Aedes albopictus can transmit flaviviruses sexually...
Species identification is an essential ability in every conservation initiative. An efficient and robust computer vision method was attested with available online tool Google's Teachable Machine. This pilot study on developing a species recognition app to create evaluate the usability accuracy of using Machine for at Teluk Air Tawar, Kuala Muda (TAT-KM), Malaysia. The created models evaluated compared training images based web-mining (Google Images Repository) actual photos taken same site....
Plant derived insecticides have considerable potential for mosquito control because these products are safer than conventional insecticides. This study aimed to investigate sublethal activities of Ipomoea carica or railway creeper crude acethonilic extract against life history trait dengue vectors, Aedes albopictus and aegypti. The late third instar larvae Ae. aegypti were exposed a dose at LC50 that survived further cultured. Overall, Ipomea cairica extracts affected the whole both species....
Abstract In this paper, we emphasize the importance of understanding nesting ecology and behaviour green marine turtles ( Chelonia mydas ). Data were collected from 2007 until 2012 beaches at Setiu Terengganu, Malaysia. We focused on one beaches, Telaga Papan, based data in 2012. recorded distribution areas, emergence hour correlation between successful attempts false crawls. Papan had a significantly higher turtle compared with other five ANOVA , F 5,42 = 8.874, P < 0.01, mean 36.750 ±...
Nocturnal mammals constitute a crucial component of tropical faunal diversity, but not much is known about the effects anthropogenic disturbance on habitat use and detectability these species. We investigated which environmental variables impact non-volant nocturnal arboreal across varying types at two islands with different levels development in Malaysia. conducted night transect line point count surveys following pre-existing paths Penang Island Langkawi between 2019 2020. used head torch...
Paederus fuscipes, a vector of dermatitis in most tropical and subtropical countries the world have high prevalence human dwellings due to their positively phototaxic behaviour which has caused tremendous impact on health. In this paper, P. fuscipes dispersal flights were studied for two seasons rice cultivation phases residential premises built close field areas (≈32-60 m 164 m) mainland Penang, Malaysia. We examined effects different light illuminance, building floor level association with...
To evaluate the current knowledge level and information on Aedes mosquitoes dengue among Penang resident in urban (Sungai Dua) sub-urban areas (Batu Maung). The questionnaire comprises of twenty-three questions, surveyed 202 respondents regarding socio-demographic, observation general Aedes' mosquito behaviour, infection threat, preventive measures against lifestyle (on usage artificial light) changing behaviour mosquitoes. Batu Maung showed less as compared to Sungai Dua. There was a...
Macaranga bancana is considered as a successful pioneer plant species. Usually found in disturbed and open areas, most of the current research focused on its relations with ants. One unique feature plants that seedling leaves are red, resembling almost matching background. Using portable spectrometer, we measured color reflectance M. seedlings (less than 20 cm height). We also leaf litter reflectance, adult several other species vicinity seedlings. The reflectances very similar to suggest...
We conducted several aviary experiments to investigate the influence of colours in quantity judgments two species birds; house crow (Corvus splendens) and common myna (Acridotheres tristis). Different (in seven different food proportions) mealworms were presented nonsequentially all birds using artificially coloured red mealworms, for experiment 1, green 2. Both have no significant effect on crow's (red:F6,30 = 1.748, p 0.144; green:F6,30= 1.085, 0.394). Common myna, however, showed a strong...
The population of bats has declined from year to caused by human activities such as logging and hunting activities. Since the factor is linked issues decline in many animal species, a community-based conservation strategy that involved local communities needed. We conducted face-to-face surveys among residents Penang Island assess knowledge awareness level toward efforts. collected demographic values age, gender, education, length residency well their monthly income, since different group...
The presence of predators can have dramatic consequences on prey communities, not only by the direct effects consumption but also through sublethal effects. We investigated survival rate and subsequent life history mosquito Culex pervigilans Bergroth under influence its major predator, backswimmer Anisops wakefieldi White. established a field experiment with various treatments: 1) control without predators, 2) free-roaming A. (with one, three, or nine per container), 3) caged (empty cage in...
