Scholars studying the globalization of Australian trees have previously emphasized the rapid natural propagation of Australian trees outside of their native habitats, believing their success to be a reversal of "ecological imperialism" from the "new world" to the "old world." This article argues...

In this investigation, detection dogs are trained and used in identifying red imported fire ants, Solenopsis invicta Buren, and their nests. The methodology could assist in reducing the frequency and scope of chemical treatments for red imported fire ant management and thus reduce labor costs and...

"Droskii" is a 2-year project running in the frame of Euphresco II - an European Research Area Network (ERA-NET) project for the development and implementation of research policies in the field of statutory and emerging plant pests, diseases and invasive species - devoted to deepen the knowledge...

This thesis reports the results of long-term experimentation (since 1993) of family farmers with agroforestry (AF) coffee systems in the Brazilian Atlantic Rainforest region, a highly fragmented and threatened biodiversity hotspot. The farmers used native trees from forest fragments during a...

We consider the problem of designing a surveillance system to detect a broad range of invasive species across a heterogeneous sampling frame. We present a model to detect a range of invertebrate invasives whilst addressing the challenges of multiple data sources, stratifying for differential risk,...

Weed infestation is a major constraint to rice production. Smallholders, working with hand tools or animal draught, often rely on labour intensive hand-weeding which is difficult to complete while rice seedlings are most vulnerable to weed competition. Pro-poor approaches to improving rice...

The shrub species Tithonia diversifolia is widely distributed along farm boundaries in the humid and subhumid tropics of Africa. Green biomass of tithonia has been recognized as an effective source of nutrients for lowland rice (Oryza sativa) in Asia and more recently for maize (Zea mays) and...

Studies were conducted in plantations of arecanut (Areca catechu) cv. Srivardhan Rotha in Raigad district, Maharashtra, to determine the comparative economics of different plantation sizes. Yield of dry nuts was highest (1238.98 kg/ha) in medium-sized plantations (0.58 ha). Where mixed cropping...

Stomp (pendimethalin), Goal (oxyfluorfen),Modown (bifenox) and Onecide [fluazifop] were tested on seven coniferous (Pinus koraiensis, P. densiflora, P. thunbergii, Pinus rigida × P. taeda, Chamaecyparis obtusa, Cryptomeria japonica, Larix leptolepis) species and on Betula platyphylla var. japonica...
