Ant parasitoidism has been reported in seven of the 26 recognized species of the mite genus Macrodinychus (Machrodynichidae). Macrodynichus sellnicki, previously reported as a parasitoid of the invasive ant Nylanderia fulva in Colombia, is now reported, in the same region, as attacking a native host, Ectatomma sp. 2 (E. ruidum complex). The mite develops within the protective silk cocoon of an Ectatomma pupa and waits for the emergence of the young ant before leaving the cocoon, unmolested. Overall nest prevalence was relatively high (34.6% of the 52 nests containing cocoons) but pupae prevalence was low (4.0%, n=1401 cocoons). Mite life-history (parasite or parasitoid) was context dependent, shifting according to the intensity of the attack on a same host. Contrary to the strictly parasitoidic association of M. sellnicki with N. fulva, single mite attacks against E. ruidum did not result in host killing and solitary M. sellnicki (78.6% of the cases) behaved as parasites. However, in 21.4% of the attacks (0.9% of all available host pupae) more than one mite was involved and behaved as parasitoids, draining the host of its internal fuids and killing it. This is the frst association of a macrodinychid mite with a species of the subfamily Ectatomminae, and the frst ant associated mite for which such a context dependent life-style shift is described.

The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Eucharitidae are parasitoids that use immature stages of ants for their development. Kapala Cameron is the genus most frequently collected in the Neotropics, but little is known about the biology and behavior of any of the species of this genus. We aimed to evaluate the effect of habitat type on eucharitid parasitism and to contribute to the knowledge of the host-parasite relationship between Kapala sp. and the poneromorph ant Ectatomma ruidum (Roger) in Colombia. Twenty E. ruidum colonies were extracted from two different habitat types (woodland and grassland), and larvae and cocoons (pupae) were examined in search for parasitoids in different stages of development. Globally, 60% of the colonies were parasitized, with 1.3% of larvae and 4% of pupae parasitized. Planidia (first-instar larvae), pupae, and adults of the parasitoid were observed. All of the pupae and adult parasitoids belonged to Kapala iridicolor Cameron. All the colonies collected in the woodlands were parasitized and contained more parasitized larvae (2%) and parasitized cocoons (8%) than those collected in grasslands (4/12 parasitized colonies, 0.5% parasitized larvae, 0.8% parasitized cocoons). The relationship observed between habitat type and parasitism prevalence is a novel aspect of the study of eucharitid impact on ant host populations.

Resumen en inglés

Ectatomma ruidum is a common ground-dwelling ant species in the Neotropics which has been reported as a potential biocontrol agent in maize and coffee-cocoa agroecosystems in Mexico and Nicaragua. Its spatial distribution and food preferences were evaluated between February and May 2007, both in shaded (with tree cover) and sunny (open) cattle pastures in the Pescador and El Palmar regions of southwestern Colombia. Two sunny and two shaded cattle pasture plots were selected at each region. Twenty consecutive, equilateral 25 m2 parcels were established at each plot. Nest locations were found by following trails from 20 equidistant tuna baits per parcel. The procedure was repeated during the wet and dry seasons with a total of 16 plot records. For determining food preferences, a paper disk providing five live ticks, five honey droplets and five Passiflora ligularis seeds was placed 30 cm away from the nest entrance, at one nest for each of 15 parcels per plot.

Nest distribution was aggregated in shaded pastures, with an average nest density of 568 nests/ha, whereas it was mainly random in sunny pastures, with an average nest density of 1945 nests/ha. Whatever the season, E. ruidum nested preferentially in open places in both regions, apparently avoiding soil surfaces under the tree canopy cover in shaded pastures. This could explain the aggregated pattern recorded in these pastures despite some intraspecific competition. Foragers demonstrated a high capacity as seed dispersers, the myrmecochoric P. ligularis seeds representing 74.7% of the total weight of all food items removed. Comparatively, they were significantly less attracted by honey and ticks which were retrieved in similar quantities (14.3% and 11.0% of the total weight removed, respectively). In the course of this study, individual workers were observed carrying in their mandibles wild, natural ticks, captured in the field. This is the first report of ants naturally preying on ticks in Colombia. Our data confirm the status of E. ruidum as an important natural biocontrol agent which could be properly managed for ecological services in Neotropical agroecosystems.

Resumen en español

Diversos estudios han documentado las pérdidas de biodiversidad debido a la intensificación del manejo de café (disminución de la riqueza y complejidad del dosel). Sin embargo, persisten preguntas sobre la sensibilidad relativa de diferentes taxa, especialistas de hábitat y grupos funcionales, y sí las implicaciones para la conservación de la biodiversidad varían entre regiones. Revisamos cuantitativamente los datos de estudios de biodiversidad de hormigas, aves y árboles en agroecosistemas de café para abordar las siguientes preguntas: ¿La riqueza de especies declina con la intensificación o con las características individuales de la vegetación?¿Hay pérdidas significativas de riqueza de especies en los sistemas cafetaleros en comparación con los bosques?¿Es mayor la pérdida en especies de bosque o en grupos funcionales particulares? y ¿Las aves o las hormigas son más afectadas por la intensificación? En los estudios revisados, la riqueza de hormigas y aves declinó con la intensificación del manejo y con los cambios de vegetación. La riqueza de especies de todas las hormigas y aves y la de especies de hormigas y aves de bosque fue menor en la mayoría de los agroecosistemas cafetaleros que en los bosques, pero el café rústico (cultivado bajo dosel de bosque nativo) sustentó la mayor pérdida de especies, y la pérdida de especies de hormigas, aves y árboles de bosque aumentó con la intensificación del manejo.

Las pérdidas de especies de hormigas y aves fueron similares, aunque las pérdidas de hormigas de bosque fueron más drásticas en el café rústico. La riqueza de especies de aves migratorias y de aves que forrajean en varios estratos de vegetación fueron menos afectadas por la intensificación que las especies residentes de dosel y de sotobosque. Las fincas rústicas protegieron más especies que otros sistemas cafetaleros, y la pérdida de especies dependió mayormente de la especialización de hábitat y de los atributos funcionales. Recomendamos que el bosque sea protegido, se promueva el café rústico y se restauren las fincas intensivas mediante el incremento de la densidad y riqueza de árboles nativos y permitiendo el crecimiento de epífitas. También recomendamos que las futuras investigaciones enfoquen las compensaciones potenciales entre la conservación de la biodiversidad y la forma de vida de los campesinos que producen café.

Resumen en inglés

Studies have documented biodiversity losses due to intensification of coffee management (reduction in canopy richness and complexity). Nevertheless, questions remain regarding relative sensitivity of different taxa, habitat specialists, and functional groups, and whether implications for biodiversity conservation vary across regions.We quantitatively reviewed data from ant, bird, and tree biodiversity studies in coffee agroecosystems to address the following questions: Does species richness decline with intensification or with individual vegetation characteristics? Are there significant losses of species richness in coffee-management systems compared with forests? Is species loss greater for forest species or for particular functional groups?and Are ants or birds more strongly affected by intensification? Across studies, ant and bird richness declined with management intensification and with changes in vegetation. Species richness of all ants and birds and of forest ant and bird species was lower in most coffee agroecosystems than in forests, but rustic coffee (grown under native forest canopies) had equal or greater ant and bird richness than nearby forests.

Sun coffee(grown without canopy trees) sustained the highest species losses, and species loss of forest ant, bird, and tree species increased with management intensity. Losses of ant and bird species were similar, although losses of forest ants were more drastic in rustic coffee. Richness of migratory birds and of birds that forage across vegetation strata was less affected by intensification than richness of resident, canopy, and understory bird species. Rustic farms protected more species than other coffee systems, and loss of species depended greatly on habitat specialization and functional traits. We recommend that forest be protected, rustic coffee be promoted,and intensive coffee farms be restored by augmenting native tree density and richness and allowing growth of epiphytes. We also recommend that future research focus on potential trade-offs between biodiversity conservation and farmer livelihoods stemming from coffee production.

Resumen en inglés

Most native forests in Latin America are highly fragmented. In the mid elevation areas of Northern Latin America, the agricultural matrix is frequently composed of coffee. In this region, coffee has been traditionally cultivated under the diverse canopy of shade trees, representing a high quality matrix that can contribute to the social and ecological stability of the region. This agroforestry system has been proven to be important for biodiversity conservation. Studies over the last fifteen years have shown that shaded coffee plantations maintain a high diversity of vertebrates, invertebrates and plants. These organisms play an important role in the functioning of coffee agroecosystems. Shaded coffee plantations promote a high abundance and diversity of natural enemies that help to regulate herbivores, weeds and diseases. Shaded plantations also harbor a higher diversity of native pollinators which have been shown to contribute to higher coffee yields. Likewise, the diverse shade-tree component contributes to soil fertility and soil conservation and has been shown to contribute significantly to carbon sequestration.

As a matrix, coffee agroforests also contribute to the conservation of biodiversity withinforest fragments by promoting migration among fragments and facilitating a metapopulation structure. Three “sustainable” coffee certification programs have been developed to help farmers cope with the vagaries of the market: organic, fair-trade and biodiversity-friendly (or shade-grown). Although certified coffees still represent a small niche market, they have the potential to promote conservation and benefit the livelihoods of small producers. Especially under conditions of low international coffee prices, as those experienced in the first years of this century, these certification programs have contributed to the ecological and socio-economic stability of the coffee growing regions of northern Latin America.
