Abstract:
... The global land area devoted to rubber plantations has now reached 13 million hectares, and the further expansion of these rubber plantations at the expense of tropical forests will have significant adverse effects on the ecological environment. Rubber-based agroforestry systems are considered a preferable approach for ameliorating the ecological environment. Many researchers have focused on the p ...

Abstract:
... Forest biomass and carbon are critical for ecological monitoring, and yet poorly modelled in complex ecosystems such as the tropical rainforests. To overcome this challenge incurred due to the complex biophysical properties of tropical forests, Airborne and Terrestrial LiDAR (Light Detection and Ranging) technologies have been used combinedly. Airborne LiDAR data ‘from above’ are largely restricte ...

Abstract:
... We report on phyllostomid assemblages just after a wildfire and again three months later across burned and unburned forest patches. We recorded 10 species throughout the fire disturbance gradient, mainly determined by changes in the understory. Burned patches presented high abundance of predator bats right after fire, including gleaning insectivorous, carnivorous, and sanguivorous. Three months la ...

Abstract:
... Seed dispersal by ants is an important interaction in North American eastern deciduous forests, where 30–40% of understory plants are myrmecochores, with seeds that possess lipid‐rich appendages (elaiosomes) that attract seed‐dispersing ants. Contemporary forests are fragmented and have regenerated from being previously cleared (secondary forests). In secondary forests, and especially along edges, ...

In this study, we describe a new low‐cost technique to collect plant‐inhabiting arthropods at a height of up to 10 m without the need for specialized and complicated methods such as rope climbing or fogging. We present a model to build and apply the technique in a tropical forest understory. This technique is important because it is not only efficient for arthropod collection, it also enables a va ...

Abstract:
... Climate warming impacts biological systems profoundly. Climatologists deliver predictions about warming amplitude at coarse scales. Nevertheless, insects are small, and it remains unclear how much of the warming at coarse scales appears in the microclimates where they live. We propose a simple method for determining the pertinent spatial scale of insect microclimates. Recent studies have quantifie ...

Abstract:
... Birds use social as well as environmental cues to inform their habitat selection decisions. By manipulating social cues with song playbacks, biologists can influence where individuals search for breeding territories, which could be useful for conservation. Yet before we can predict how birds will respond to playback treatments, we must first understand how they integrate social cues with informati ...

Abstract:
... The principle of acoustic allometry—the larger the animal, the lower its calls' fundamental frequency—is generally observed across terrestrial mammals. Moreover, according to the Acoustic Adaptation Hypothesis, open habitats favor the propagation of high-frequency calls compared to habitats with complex vegetational structures. We carried out playback experiments in which the calls of the Guizhou ...

... Glyphosate-based herbicides are highly effective, non-selective, and broad-spectrum herbicides that have been used in British Columbia’s forest industry since the early 1980’s. Over this time, long-term persistence of glyphosate has not been measured, largely due to the inability to analyze glyphosate at low concentrations. Given the advancements in analytical techniques that are now available, we ...
