A total of 432 snails were collected in 2020, with a prevalence of 77%, well explained by the host width frequency. Monthly prevalence varied from 54% to 90%, and the mean intensity was 1.4 +/- 0.5 crabs per host. The sex ratio of snails was 1:1, and the crab did not prefer to infest males or females. The sex ratio of the crabs was positively skewed towards females. Crabs infested both small and large snails; however, most infested snails ranged between 20 and 40 mm in width. Prevalence increased with the host size: with hosts smaller than 30 mm experiencing an average of 53% infestation, while those from 30 mm to 52 mm averaged 93% infestation. The number of crabs by host varied from 1 to 3; solitary females and males were dominant (51%), followed by heterosexual couples (24%) and other combinations that included homosexual couples and triads, which barely represented 2%. Although there are many heterosexual couples, monogamy is ruled out due to the higher number of solitary males and females and the lower number of heterosexual couples compared to those statistically expected.

However, many of these wetlands face threats of disappearance and degradation, with potential consequences for the species inhabiting them. Here, we carried out a detailed study of the breeding biology of this species and examined variables that influence daily nest survival rates (DSR). We described nest site features, nest morphometry, breeding parameters, estimated the growth curves of nestlings, and recorded the causes of nest failure. We evaluated the effects of nest site features, nest morphometry, nest age and timing of breeding season on the DSR of Chestnut-capped Blackbirds. We expected that DSR would increase with greater nests and higher nest concealment at the beginning of the breeding season. Additionally, we predicted that larger nests would have higher nest survival. We studied the breeding performance of 138 nests in a wetland in central Argentina over three consecutive breeding seasons. Nests were placed 80 ± 21.53 cm above the water. The clutch size was 2.75 ± 0.67 eggs (<i>n</i> = 84 nests), and the brood size was 2.28 ± 0.79 nestlings (<i>n</i> = 49 nests). The most frequent cause of nest failures was predation (60%). The daily nest survival rate (DSR) was 0.96, and the cumulative probability of nest survival in a 29-day breeding cycle was 0.31 (<i>n</i> = 85 nests). As expected, we found a positive association between nest height above the water and DSR, suggesting that nests built further away from the water have increased survival rates.

In this study we analyzed a) the seasonal variations in abundance and richness of dung beetle assemblages in two contrasting habitats within a ranch in Uruguay, and their relationship with environmental factors; b) the influence of the habitat on the daily patterns of flight activity of dung beetles, as well as seasonal and daily changes species composition; and c) the seasonal variations of daily activity patterns of the most abundant species. We sampled dung beetles every two weeks for a year with pitfall traps baited with carrion and cow and horse excrements in an open grazed pasture and a <i>Eucalyptus</i> plantation, used as a shelter for livestock. Each 24-hour sampling was divided into 5 intervals: morning, noon, afternoon, evening, and night. The seasonal variations of abundance and species richness of Scarabaeidae in both habitats were similar from midspring to mid-autumn, without activity in the winter season; temperature influenced these patterns. Diurnal dung beetles were more abundant than crepuscular and nocturnal in the open habitat but not clearly in the <i>Eucalyptus</i> plantation. However, the abundance and richness of nocturnal species were similar in both habitats. The daily activity period significantly influenced the segregation of dung beetles in both habitats. Species composition differed markedly between diurnal and crepuscular/nocturnal species without changes across seasons. Scarabaeinae species were mostly diurnal in grassland, while a nocturnal species was predominant in <i>Eucalyptus</i> plantation. Aphodiinae species were mainly active at dusk and night.

This research examined the zooplankton community dynamics in the western Gulf of Mexico during three seasons: July 2010 (summer), January 2011 (winter), and October-November 2012 (fall), and the possible effect of the warm eddy called Jumbo, released from the Loop Current in the middle of 2012 and that approached the western side of the gulf at the end of the year. We hypothesized shifts in the composition and/or biomass of the zooplankton fauna collected during the fall period due to the transport of organisms from elsewhere or because of a rapid response of zooplankton to warmer environmental conditions. This could result in a greater similarity of the fall season to the summer rather than to the winter. Zooplankton samples were taken onboard the oceanographic vessel Justo Sierra and a total of 82 oceanographic stations were sampled with a Bongo net; at each sampling station, temperature and salinity were measured with a CTD profiler. Both environmental and zooplankton data were treated through a Principal Coordinate Analysis (PCO) to explore their relationship. Fourteen zooplankton groups were recognized in all three sampling periods, with seasonal variations in biomass. The PCO showed that July was characterized by high-temperature values (~27°C), low chlorophyll concentration (< 1 mg/m³), the dominance of copepods, chaetognaths, and luciferids, as well as high biomass values of crustacean larvae (decapods stomatopods), signaling this season as the reproductive period. January was characterized by higher chlorophyll concentration (1-1.3 mg/m³), lower temperatures (18-22°C), and a high biomass of amphipods, ostracods, and jellyfishes; October-November registered similar environmental conditions to July, but the PCO and the associated distance among centroids indicated that the zooplankton community structure was more similar to January. The occurrence of the 14 groups in all the seasons, reveals no shifts in the composition in the study area. Besides, the similarity of the fall to the winter in the zooplankton structure discarded the hypothesis.

Live grounded birds were rescued and released when possible, or euthanized. Groundings were mapped at the scales of both Grande Terre and Nouméa, the main city. Negative binomial regression was used to analyze the effects of light intensity and proximity to shore on the number of groundings. Of the 523 grounded seabirds recorded between 2007 and 2009, 80.2% were wedge-tailed shearwaters (<i>Ardenna pacifica</i>), 14.2% were Gould's petrels (Pterodroma leucoptera), and 5.4% were Tahiti petrels (<i>Pseudobulweria rostrata</i>). Combining all three species, an estimated 64.9% of grounded individuals were fledglings. Groundings of Gould's petrels and wedge-tailed shearwaters peaked during their respective fledging seasons (April and May). The number of lights and the proximity to shore were identified as highly significant positive factors explaining the number of groundings.
