Agricultural management and the landscape surrounding farms impact biological diversity and ecosystem services, such as predation, in agroecosystems. Diversified coffee agroecosystems harbor biodiversity, and maintain ecosystem services, especially when in complex landscapes, and when diversity of organisms providing services is maintained. But few have examined whether biological diversity, per se, or the local and landscape habitat features are stronger drivers of the services provided. We studied the relationships between local characteristics associated with agricultural management (vegetation complexity and agrochemical use), landscape surroundings of farms, abundance and richness of ants, and predation services provided by ants in a tropical coffee landscape. Specifically, we tested whether: (1) ants remove prey items and prey removal differs in the wet and dry season, (2) ant prey removal differs in farms that vary in vegetation complexity and agrochemical use, (3) ant prey removal differs with changes in ant abundance and species richness, and (4) ant prey removal differs with changes in local and landscape characteristics. We established sites across a range of coffee management systems, at varying distances to forest fragments, and in forest fragments and examined prey removal by ants on the ground, coffee branches, and shade tree trunks in the wet and dry season. Prey removal did not differ with season. Prey removal on the ground increased within increases in ant abundance and richness, and number of hollow coffee twigs.

Prey removal on coffee plants decreased with vegetation complexity, but increased with ant abundance and richness, coffee density (a local factor), and rustic coffee within 200 m (a landscape factor). Prey removal on trees declined with vegetation complexity, but increased with abundance and richness of ants. Characteristics of the ant community were consistent predictors of prey removal, whereas local and landscape habitat features were less important, and only three habitat features correlated with prey removal. Our results demonstrate the positive effects of ant diversity for predatory function, and that promoting pest control services within coffee agroecosystems may be best accomplished by manipulating ant abundance and richness, or vegetation factors that correlate with ants.

Resumen en inglés

Arthropods in several orders use traps to capture prey. Such trap-building predators expend most of their foraging energy prior to any prey contact. Nevertheless, relative investments in trap construction and actual prey capture may vary among trap builders, and they are likely to face a trade-off between building very effective but energetically costly traps and building less effective traps requiring faster reaction times when attacking prey. We analysed this trade-off in a field experiment by comparing the prey capture behaviour of four different sympatric web-building spiders (Araneae: Araneidae, Nephilidae, Tetragnathidae, Theridiidae) with the retention times of five different prey types in the webs of these spiders. Retention times differed greatly among webs and among prey types. The vertical orb webs retained prey longer than the horizontal orb web and the sheet web, and active prey escaped more quickly than less active prey. Among spiders with orb webs, the spider with the web that retained prey for the shortest time was the fastest to capture prey, thus confirming the expected trade-off between building long-retaining webs and attacking slowly versus building short-retaining webs and attacking more rapidly. The sheet web, however, neither retained prey for an appreciable period of time nor facilitated rapid prey capture. We suggest that this low capture effectiveness of sheet webs is compensated by their lower maintenance costs.

Resumen en frances

L'utilisation de pièges pour capturer des proies est assez répandue chez les arthropodes. Ces prédateurs dépensent la majeure partie de leur énergie de recherche de nourriture dans la construction du piège avant tout contact avec la proie. Cependant la quantité relative d'énergie investie pour la construction du piège et celle investie dans la capture de la proie peuvent varier suivant les prédateurs qui peuvent construire un piège très efficace et coûteux ou un piège moins efficace et moins coûteux, mais qui demande des réactions plus rapides au moment de la capture de la proie. Nous avons analysé ce choix stratégique en comparant les comportements de capture des proies de quatre araignées tisseuses de toiles sympatriques (Araneae : Araneidae, Nephilidae, Tetragnathidae, Theridiidae) en fonction de la durée de la rétention sur la toile de cinq types différents de proies. Les durées de rétention diffèrent grandement suivant les différentes toiles et les types de proies. Les toiles orbitèles verticales retiennent plus longuement les proies que les toiles orbitèles horizontales ou les toiles en nappe. Les proies les plus actives s'échappent plus rapidement de la toile. Chez les araignées tisseuses de toiles orbitèles, celle qui possède la toile avec le temps de rétention le plus court a la réaction de capture la plus rapide; ce résultat confirme l'existence d'un compromis entre les pièges très efficaces mais avec un moindre investissement du côté du comportement de capture et les des pièges moins efficaces mais avec un comportement de capture plus rapide. La toile en nappe ne retient cependant pas les proies longuement et ne permet pas une capture rapide de la proie. Nous suggérons que la faible efficacité de ces toiles en nappe est compensée par leur coût d'entretien faible.

Resumen en inglés

We tested the hypothesis that coffee systems with organic management have higher spider diversity by comparing a control (rainforest area) and two coffee systems, one with organic and the other with conventional management. Spiders were sampled every two weeks over three months during the dry season and three months during the rainy season in 2000. Spider alpha diversity was analyzed using Shannon and Simpson indices. We also used the Cody index for beta diversity and cluster analysis for analyzing changes in species abundance hierarchies. 2261 individuals were collected (including juveniles and adults) representing 20 families, 56 genera and 97 species. In most cases the alpha diversity indices showed no relation between management gradient and spider diversity. When compared across seasons, spider diversity differed significantly only in organic management. Species turnover among the three sites (Cody index) was highest between the two coffee farms but not so clearly in the dry vs. rainy season; the conventional management shared the fewest species with the forest. Cluster analysis showed changes in abundance hierarchy related to management type. Our results did not support the proposed hypothesis of a direct positive correlation between management gradient and alpha spider diversity. In contrast, beta diversity showed that management and seasons influenced species composition. Keywords: Araneae, agroecosystems, management gradient, species composition

Resumen en inglés

The distribution of female Leucauge venusta (Walckenaer 1841) in a coffee plantation in southern Mexico was studied in order to determine the vertical distribution of this spider. Principal component analysis clearly identified the presence of three distinct groups of L. venusta webs, based on the number of spirals/web and principally on the height at which the webs were located; most L. venusta webs (63/100) were close to the ground. Spiders on high webs (153.8 + 3.6 cm above ground, mean t S.E.) were significantly larger and heavier than spiders on lower webs. Large spiders had significantly larger, better developed ovaries, than smaller conspecifics, presumably indicative of sexual maturity. Significantly more insects were captured by sticky traps placed at 50 cm height than in the traps placed at 150 cm height; the most numerous captures were Diptera. However, insects caught at 150 cm were significantly larger than those caught at 50 cm above ground. We concluded that as sexual development proceeds, the spider increases the height at which the web is constructed. This vertical migration is associated with changes in web construction and the type of prey captured. These results are discussed in terms of intraspecific competition, predation risks and sexual selection.

Resumen en inglés

The role of Azteca sp. ants as potential biological control agents was studied in an organic coffee farm in Chiapas, Mexico. Individual larvae of Pieris rapae were placed on trees with artificially enhanced ant activity and both time to disappearance of the larvae and ant activity were recorded. There was a general negative relationship between time to disappearance and ant activity. A census of spiders was made of coffee bushes with and without foraging Azteca, encountering a negative relationship between ants and spiders. These results indicate that Azteca ants have potential as pests through their positive effect on scale insects, but also have potential as biological control agents, through their negative effect on potential herbivores. Furthermore, the correlation between ant and spider densities suggests a complicated relationship between these two predatory organisms, implying a more complicated food web structure than simply ants, homoptera and other herbivores.
