Seed consumption by small fish follows peak seed availability in a tropical dry forest river
<p>Seed consumption and dispersal by fish has been more extensively described in natural Neotropical large river systems of Amazonia, where ichthyochory follows a seasonal gradient associated with a floodpulse that creates long-lasting seasonally flood zones. It has been shown that it is relevant in maintaining the plant community structure of wetlands, but its effects on plant communities in seasonal dry forests are largely unknown. The Amacuzac hydrological system, which runs through one of the most extensive seasonal tropical dry forests of Central Mexico, shows a marked climatic seasonality, which in turn determines a transient increase in river flow and its potential to overflow, resulting in a drag effect on banks, and in the river carrying three times more seeds in the rainy than in the dry season. Another characteristic of the system is the coexistence of native and non-native fish species, due to the fact that the middle part of the river receives discharges from four tributaries that cross important urban, industrial, and agricultural districts as well as an extensive network of ornamental fish farms. Therefore, we hypothesize that rates of seed consumption by fish would correspondingly increase during rainy seasons, and that both native and non-native fish would consume seeds in similar proportions. We evaluated seed consumption by fish by (a) identifying and estimating the frequency and number of fish species whose stomachs contained seeds, and determining the percentage of each fishes' diet corresponding to seeds with respect to total food items, and (b) by evaluating if there were seasonal differences in the consumption of intact seeds by fish and between native vs. non-native species. We found two native species - <i>Astyanax aeneus</i> and <i>Notropis moralesi</i>, and two non-native species - <i>Aequidens rivulatus</i> and <i>Amatitlania nigrofasciata </i>containing seeds in their stomachs. The number of individuals with seeds was significantly higher in the rainy season than in the dry season, with a higher proportion of non-native fishes carrying seeds, but only in the rainy season. We found significant differences between the fish species in the proportion of seeds consumed. Fishes follow the peak of seed availability after a flood pulse released them from the soil seed banks. Thus, fishes consume fruits/seeds on a seasonal basis, however in this case it is explained by a different mechanism other than the timing of seed production by trees. As with hydrochory in tropical dry forests, seed consumption/dispersal by fish inhabiting rivers within this ecosystem has been overlooked in the ecology and conservation literature. This evidence is relevant for tropical dry forest ecosystem dynamics and management strategies in riparian corridors.</p> <p> </p>

Seed dispersal by carnivores in temperate and tropical dry forests
<p>The seed dispersal mechanisms and regeneration of various forest ecosystems can benefit from the actions of carnivores via endozoochory. This study aims to evaluate the role of carnivores in endozoochory and diploendozoochory, as well as their effect on seed viability, scarification, and germination in two forest ecosystems: temperate and tropical dry forest. We collected carnivore scat in the Protected Natural Area of Sierra Fría in Aguascalientes, Mexico, for two years to determine the abundance and richness of seeds dispersed by each carnivore species, through scat analysis. We assessed seed viability through optical densitometry using X-rays, analyzed seed scarification by measuring seed coat thickness using a scanning electron microscope, and evaluated seed germination in an experiment as the percentage of seeds germinated per carnivore disperser, plant species, and forest type. In the temperate forest, four plant species (but mainly <i>Arctostaphylos pungens</i>) were dispersed by four mammal species. The gray fox dispersed the highest average number of seeds per scat (66.8 seeds). Bobcat dispersed seeds through diploendozoochory, which was inferred from rabbit (<i>Sylvilagus floridanus</i>) hair detected in their scats. The tropical dry forest presented higher abundance of seeds and richness of dispersed plant species (four species) than in the temperate forest, and the coati dispersed the highest number of seeds (8639 seeds). Endozoochory and diploendozoochory did not affect viability in thick testas seeds in temperate forest and thin testas seeds in tropical dry forest. Endozoochory improved the selective germination of seeds. Nine plant species were dispersed by endozoochory, but only one species (<i>Juniperus sp</i>.) by diploendozoochory. These results suggest that carnivores can perform an important ecological function by dispersing a great abundance of seeds, scarifying these seeds causing the formation of holes and cracks in the testas without affecting viability and promoting the selective germination of seeds.</p>
