Livelihood gains and ecological costs of non-timber forest product dependence: assessing the roles of dependence, ecological knowledge and market structure in three contrasting human and ecological
Non-timber forest products (NTFPs) constitute the single largest determinant of livelihoods for scores of forest fringe communities and poor people in the tropics. In India over 50 million people are
Impact of the invasive plant, Lantana camara, on bird assemblages at Malé Mahadeshwara Reserve Forest, South India
TLDR
It is suggested that Lantana affects the structure of the bird community by decreasing diversity, and that Lantsana affects certain guilds more than others, including canopy birds and foraging guilds.
A natural history of web decorations in the St Andrew’s Cross spider (Argiope keyserlingi)
A long-running debate in the spider literature concerns the function of the extra silk decorations in some spider webs. These decorations are appended to the web and constitute a highly visible
The aggregating behaviour of Argiope radon, with special reference to web decorations
TLDR
The results show that A. radon aggregates facultatively and that the main benefit of aggregation that the authors could identify is enhanced mating potential, and suggest that solitary individuals with longer and more frequent decorations may offset the foraging advantage of being in aggregations.
The effect of irradiation and mass rearing on the anti-predator behaviour of the Mexican fruit fly, Anastrepha ludens (Diptera: Tephritidae)
TLDR
Although all flies performed a supination display to their predator, wild flies were more likely to perform a display and were significantly more successful in avoiding attack than mass-reared flies.
Spider diversity in epiphytes: Can shade coffee plantations promote the conservation of cloud forest assemblages?
TLDR
A diversity assay of spiders living in epiphytes in cloud forest fragments and SC plantations is conducted, to test the hypothesis that SC plantations function as refugia for spider fauna from the surrounding cloud Forest fragments.
Characterisation of Predator‐Directed Displays in Tephritid Flies
TLDR
The results suggest that tephritid flies deter attacks because of their display and not their appearance, and that the presence or absence of bands does not alter the possibility of attack.
Experimental Evidence for the Amelioration of Shadow Competition in an Orb‐Web Spider Through the ‘Ricochet’ Effect
TLDR
This study shows experimentally that a spider that builds its web close to a conspecific’s web suffers very little cost in terms of lost prey interception, and the degree of overlap between the webs significantly influences both the number of prey intercepted as well as thenumber of ricochets.
Reverse positional orientation in a neotropical orb-web spider, Verrucosa arenata
TLDR
It is shown that reverse orientation does not imply reverse web asymmetry in Verrucosa arenata, a neotropical orb-web spider that faces upwards in the web, and that V. arenata spiders captured more prey in the lower part of the web but more prey per area on the upper part.
