Basic morphometric and demographic data was collected for the spiny lobster, Panulirus interruptus, around the west end of Santa Catalina Island from Spring 2003-Spring 2005. This region includes two marine protected areas, many popular sport fishing and diving sites, and a continuous stretch of coastline that is commercially fished. Lobsters were caught using commercial lobster traps without juvenile escape ports and mackerel as bait. Traps were set on the first day at randomly selected sites within a blocked sampling scheme and allowed to sit overnight. On the second day, traps were collected and all lobsters within were evaluated on a number of parameters including (but not limited to) carapace length, weight, gender, and fertility state. Animals were marked with either a uropod punch code, colored cable tie, or floy tag to determine movement patterns and growth rates in the event of recapture.

Data were collected every year in spring and fall from 1994 to 2007 at Bird Rock and Little Harbor in replicated fixed plots. Percent cover of target species and associated core species was assessed by point-contacts from photographs (photoplots) and in-situ (transects). The purpose of the data was to evaluate seasonal and long-term abundance trends for comparison among over 80 other regional sites throughout California associated with the Multi-Agency Rocky Intertidal Network.

Comprehensive demographic dataset for Catalina, Santa Fe, NM, US including population statistics, household income, housing units, education levels, employment data, and transportation with year-over-year changes.

Data were collected annually in spring from 1984 to 2007 at WMSC seawater intake pipes and Bird Rock along fixed band transects (3m by 60m) at 3 depths (5m, 10m, 15m). Seastars Pisaster giganteus and Patiria miniata were counted and measured in each transect. The purpose of the data is to evaluate long-term abundance trends, particularly with relation to seastar wasting disease outbreaks.

The Census Bureau (https://www.census.gov/) maintains geographic boundaries for the analysis and mapping of demographic information across the United States. Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution. The Census Bureau releases the results of this county as demographic data with geographic identifiers so that maps and analysis can be performed on the US population.

In this study, we examined the prevalence, pathology, and epidemiology of tumors in free-ranging island foxes occurring on three islands in the California Channel Islands, USA. We found a remarkably high prevalence of ceruminous gland tumors in endangered foxes (Urocyon littoralis catalinae) occurring on Santa Catalina Island (SCA) - 48.9% of the dead foxes examined from 2001-2008 had tumors in their ears, and tumors were found in 52.2% of randomly-selected mature (≥ 4 years) foxes captured in 2007-2008, representing one of the highest prevalences of tumors ever documented in a wildlife population. In contrast, no tumors were detected in foxes from San Nicolas Island or San Clemente Island, although ear mites (Otodectes cynotis), a predisposing factor for ceruminous gland tumors in dogs and cats, were highly prevalent on all three islands. On SCA, otitis externa secondary to ear mite infection was highly correlated with ceruminous gland hyperplasia (CGH), and tumors were significantly ...

Allen's Hummingbird comprises two subspecies, one migratory (Selasphorus sasin sasin) and one non-migratory (S. s. sedentarius). The non-migratory subspecies, previously endemic to the California Channel Islands, apparently colonized the California mainland on the Palos Verdes Peninsula some time before 1970, and now breeds throughout coastal southern California. We sequenced and compared populations of mainland non-migratory Allen's Hummingbird to Channel Island populations from Santa Catalina, San Clemente, and Santa Cruz Island. We found no evidence of founder effects on the mainland population. Values of nucleotide diversity on the Channel Islands were lower than those on the mainland. There were low levels of divergence between the Channel Islands and the mainland, although Santa Cruz Island was the most genetically distinct. Ecological niche models showed that rainfall and temperature variables on the Channel Islands are similar in the Los Angeles basin, and predicted continued ex...

Understanding the spatial scale at which selection acts upon adaptive genetic variation in natural populations is fundamental to our understanding of evolutionary ecology, and has important ramifications for conservation. The environmental factors to which individuals of a population are exposed can vary at fine spatial scales, potentially generating localized patterns of adaptation. Here, we compared patterns of neutral and major histocompatibility complex (MHC) variation within an island population of Berthelot's pipit (Anthus berthelotii) to assess whether landscape-level differences in pathogen-mediated selection generate fine-scale spatial structuring in these immune genes. Specifically, we tested for spatial associations between the distribution of avian malaria, and the factors previously shown to influence that distribution, and MHC variation within resident individuals. Although we found no overall genetic structure across the population for either neutral or MHC loci, we did find localized associations between environmental factors and MHC variation. One MHC class I allele (ANBE48) was directly associated with malaria infection risk, while the presence of the ANBE48 and ANBE38 alleles within individuals correlated (positively and negatively, respectively) with distance to the nearest poultry farm, an anthropogenic factor previously shown to be an important determinant of disease distribution in the study population. Our findings highlight the importance of considering small spatial scales when studying the patterns and processes involved in evolution at adaptive loci.

Catalonia's population has been growing since 1981, when it had about six million inhabitants. By the first half of 2024, over eight million people lived in Catalonia. Of these, more than four million were women and around 3.9 million men.
